NEW QUESTION # 18
Which AppDynamics Controller port(s) does the EUM Server require access to in a configuration where the EUM Server and Controller are on separate hosts (split-host configuration)?
- A. GlassFish administration port
- B. Controller database and HTTP(s) ports
- C. dedicated EUM HTTP(s) ports
- D. Controller primary HTTP{s) port
Answer: D
Explanation:
Explanation
In a split-host configuration, where the EUM Server and Controller are on separate hosts, the EUM Server requires access to the Controller primary HTTP(s) port. This is because the EUM Server needs to communicate with the Controller API server to send data and receive configuration information. The default primary HTTP port for the Controller is 8090 and the default primary HTTPS port is 81811. The dedicated EUM HTTP(s) ports are used by the EUM agents to send data to the EUM Server, not by the EUM Server to access the Controller2. The GlassFish administration port is used to access the Controller Admin Console, not by the EUM Server3. The Controller database port is used by the Controller to connect to the MySQL database, not by the EUM Server4.

NEW QUESTION # 19
The user under which the JVM runs must have write privileges to the_________ directories in the Java Agent home. (Choose the correct option to complete the sentence.)
- A. conf and lib
- B. conf and logs
- C. lib and logs
- D. bin and logs
Answer: B
Explanation:
Explanation
The user under which the JVM runs must have write privileges to the conf and logs directories in the Java Agent home. This is because the conf directory contains the agent configuration files, such as controller-info.xml and agent-config.xml, which may need to be modified or updated by the user. The logs directory contains the agent log files, such as agent.log and agent-errors.log, which are generated by the agent and may need to be accessed or rotated by the user. The user can install the agent as the same user that owns the JVM or as an administrator on the host machine. The user can restrict the remaining contents of the agent directory, such as the lib and bin directories, to read-only access12. References: Install the Java Agent, Java Agent fails to start
NEW QUESTION # 20
Which type of Alert and Respond action is available only on an on-premises Controller?
- A. Diagnostic action
- B. Cloud auto-scaling
- C. Remediation action
- D. Custom action
Answer: D
Explanation:
Explanation
A custom action is a type of Alert and Respond action that allows you to integrate AppDynamics notifications with your own alerting or ticketing system. You can create a custom action by writing an executable script and an XML file that describe how to pass information from AppDynamics to your system. A custom action can be triggered by a policy based on a health rule violation or an event. A custom action is available only on an on-premises Controller, because it requires access to the Controller file system and the ability to execute scripts on the Controller host machine. For a SaaS Controller, you can use HTTP request templates instead of custom actions to integrate with external systems. References: Build a Custom Action, Alert and Respond, Actions, Custom Actions
NEW QUESTION # 21
What are two advantages of using an Events Service cluster? (Choose two.)
- A. Clusters are easier to maintain than single-node instances.
- B. Clusters allow data replication across multiple nodes.
- C. Clusters reduce the load on the AppDynamics Controller.
- D. Clusters are horizontally scalable by adding nodes.
- E. Clusters expose multiple channels for simultaneous queries.
Answer: B,D
Explanation:
Explanation
An Events Service cluster is a group of two or more Events Service nodes that work together to store and process unstructured data generated by AppDynamics components such as Application Analytics, Database Visibility, and End User Monitoring1. Using an Events Service cluster has two main advantages over a single-node instance12:
Clusters allow data replication across multiple nodes. This means that the data is duplicated and distributed among the nodes in the cluster, providing data redundancy and protection against data loss in case of a node failure. Data replication also improves data availability and query performance, as the cluster can handle concurrent requests from multiple clients.
Clusters are horizontally scalable by adding nodes. This means that the cluster can grow in size and capacity by adding more nodes to the cluster, without affecting the existing nodes or data. Horizontal scaling allows the cluster to handle increasing data volumes and performance demands, as well as balance the workload among the nodes. References: Events Service Deployment, What are the Benefits of Server Clustering?
NEW QUESTION # 22
Which two user accounts are created by the AppDynamies Controller during installation? (Choose two.)
- A. Elastic search root user
- B. OS user that will run the controller
- C. REST API user
- D. GlassFish asadmin user
- E. MySQL appd admin user
- F. Customer-specified Controller administrator account
Answer: D,F
NEW QUESTION # 23
The AppDynamics Controller is instrumented by an internal, out-of-the-box, AppDynamics Java agent. Which account and user name are used to connectto the Controller to view theinformation provided by the internal AppDynamics agent?
- A. The account is 'system' and the user is "root.
- B. The account is 'customer!' and the user is 'root'.
- C. The account is 'root' and the user is 'admin'.
- D. The account is internal' and the user is 'admin'.
Answer: A
Explanation:
Explanation
The AppDynamics Controller is instrumented by an internal, out-of-the-box, AppDynamics Java agent that monitors the performance and health of the Controller itself1. To access the information provided by the internal agent, you need to log in to the Controller UI with the following credentials2:
Account = system
Username = root
Password = <root_user_password>
The system account is a special account that is used only for internal monitoring and troubleshooting purposes. It is not visible in the normal Controller UI and requires a special URL to access it2. The root user is the default administrator user for the system account and has the same password as the admin user for the customer1 account3. References: Controller Self-Monitoring, Monitoring a Controller Using the Internal Monitoring Agent, Controller Accounts
NEW QUESTION # 24
Which data is unavailable in a hybrid deployment of AppDynamics where the AppDynamics Controller and Events Service are installed on-premises and the EUM Server is hosted inAppDynamics' SaaS cloud?
- A. End-User Monitoring browser snapshots
- B. Analytics metrics for End-User Monitoring data sets
- C. End-User Monitoring resource loading times
- D. End-User Monitoring session information
Answer: B
Explanation:
Explanation
In a hybrid deployment of AppDynamics, where the AppDynamics Controller and Events Service are installed on-premises and the EUM Server is hosted in AppDynamics' SaaS cloud, the data that is unavailable is the analytics metrics for End-User Monitoring data sets. This is because the analytics metrics require the Events Service to store and process the unstructured data generated by the EUM agents. However, in a hybrid deployment, the EUM Server and the Events Service are not connected, and the EUM Server does not send the EUM data to the Events Service. Therefore, the analytics metrics for EUM data sets, such as browser records, mobile snapshots, network requests, and custom events, are not available in the Controller UI or the Analytics UI1. The other data, such as resource loading times, session information, and browser snapshots, are available in the EUM Server UI, as they are stored and displayed by the EUM Server itself2. References: Hybrid Deployment and EUM Data Sets in the AppDynamics documentation.
NEW QUESTION # 25
What are three requirements to set up AppDynamics Controllers as a high availability pair? (Choose three.)
- A. A unique high availability license file is required for each Controller server.
- B. Both servers must have the Controller software installed prior to setting up high availability.
- C. Both servers must have identical directory structures for the Controller installation.
- D. The replicate sh script can be run only once.
- E. Passwordless SSH must be configured between the two Controller servers.
- F. The Controller MySQL database must be installed on a shared location.
Answer: B,C,E
Explanation:
Explanation
To set up AppDynamics Controllers as a high availability pair, you need to meet the following requirements1:
Passwordless SSH must be configured between the two Controller servers. This allows the Enterprise Console to automate the configuration and administration tasks associated with a highly available deployment on Linux systems.
Both servers must have the Controller software installed prior to setting up high availability. The Controllers in an HA pair must be equivalent versions, and be in the same data center.
Both servers must have identical directory structures for the Controller installation. The individual machines in the Controller HA pair need to have an equivalent amount of disk space. References: Prerequisites for High Availability
NEW QUESTION # 26
Which two statements are true about instrumenting standalone Windows services with NET Agent? (Choose two.)
- A. AppDynamics.NET Agent automatically discovers all the Windows services to be instrumented.
- B. AppDynamics.NET Agent requires that the Windows services is running under the "App.pool identity user" account.
- C. AppDynamics .NET Agent does NOT support instrumenting process running multiple App domains.
- D. AppDynamics .NET Agent supports instrumentation of multiple instances of the same application.
- E. AppDynamics.NET Agent can instrument both 32-bit as well 64-bit processes.
Answer: D,E
Explanation:
Explanation
The AppDynamics .NET Agent can instrument both 32-bit and 64-bit processes, as long as they are running on a supported .NET Framework version and operating system. The agent automatically detects the process architecture and loads the appropriate profiler DLL. You can also specify the process architecture manually in the agent configuration file1. The AppDynamics .NET Agent also supports instrumentation of multiple instances of the same application, such as Windows services or standalone applications. You can configure the agent to assign different tier and node names for each instance, based on the process name, process ID, or command line arguments. This allows you to monitor the performance and health of each instance separately2.
The other statements are false because:
A: AppDynamics .NET Agent does support instrumenting processes running multiple App domains. The agent can monitor multiple App domains within a single process, as long as they are running the same
.NET Framework version. The agent can also monitor multiple applications within a single App domain, by using the Standalone Applications element in the agent configuration file3.
B: AppDynamics .NET Agent does not automatically discover all the Windows services to be instrumented. The agent automatically instruments IIS applications only. For Windows services or standalone applications, you need to manually configure the agent by editing the agent configuration file and adding the Windows Services or Standalone Applications element. You also need to provide the executable name, tier name, and node name for each service or application4.
D: AppDynamics .NET Agent does not require that the Windows services are running under the
"App.pool identity user" account. The agent can instrument Windows services running under any user account, as long as the account has sufficient permissions to load the agent profiler DLL and access the agent configuration and log files. The "App.pool identity user" account is only required for IIS applications that run in an application pool5.

NEW QUESTION # 27
Which URL retrieves all AppDynamics business transactions from an application using the AppDynamics Rest API?
- A. http(s)://<controller-host>:<port>/controller/rest/applications/<application_name=>/business-transactions
- B. httpis)://<controller-host>:<port>/controller/applications/<application_name=>/allbis
- C. http(s)://<controller-host>:<port>/controller/applications/<application_name>/business-transactions
- D. http(s)://<controller-host>:<port=/controller/rest/applications/<application_name>/allbts
Answer: A
Explanation:
Explanation
The AppDynamics Rest API to retrieve business transactions allows you to get a list of all business transactions in a business application, along with their key metrics and properties1. The correct URL format for this API is1:
http(s)
://<controller-host>:<port>/controller/rest/applications/<application_name>/business-transactions The other options are incorrect because12:
Option A uses an invalid endpoint /allbts, which does not exist in the API.
Option C uses an incorrect base URL /controller/applications, which is used for the Controller UI, not the Rest API.
Option D uses a misspelled endpoint /allbis, which does not exist in the API. References: Retrieve All Business Transactions in a Business Application, AppDynamics APIs
NEW QUESTION # 28
What is the correct method to perform a NET Agent upgrade?
- A. Perform the agent upgrade on the application server host by running the MSI Installer Package.
- B. Perform the agent upgrade on the application server host by running the Agent Configuration Utility.
- C. Perform the agent upgrade on a remote server host by using the AppDynamics Controller REST API.
- D. Perform the agent upgrade via the AppDynamics Controller Ul.
Answer: A
Explanation:
Explanation
According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the correct method to perform a NET Agent upgrade is to perform the agent upgrade on the application server host by running the MSI Installer Package12. This method will install updated agent files and maintain legacy configurations. You do not need to uninstall the old agent first when you upgrade from the NET Agent >= 3.9, except for patch releases. You need to stop IIS, instrumented Windows services, and instrumented standalone applications before running the MSI Installer Package. You also need to launch an elevated command prompt with full administrator privileges and specify youraccount access key for single-tenant Controller accounts. After the installation, you need to restart Windows services and standalone applications.
The incorrect options are:
Perform the agent upgrade on a remote server host by using the AppDynamics Controller REST API.
(B) This is not a valid method for upgrading the NET Agent, because the AppDynamics Controller REST API does not provide any endpoint for agent installation or upgrade. The REST API is mainly used for retrieving or updating configuration data, metrics, events, snapshots, and other information from the Controller3.
Perform the agent upgrade on the application server host by running the Agent Configuration Utility.
This is not a valid method for upgrading the NET Agent, because the Agent Configuration Utility is a tool for modifying the agent configuration after installation, not for installing or upgrading the agent. The Agent Configuration Utility allows you to change the Controller connection settings, the agent logging level, the proxy settings, and other advanced options4.
Perform the agent upgrade via the AppDynamics Controller UI. (D) This is not a valid method for upgrading the NET Agent, because the AppDynamics Controller UI does not provide any feature for agent installation or upgrade. The Controller UI is mainly used for monitoring, analyzing, and troubleshooting the performance of the applications, business transactions, tiers, nodes, and other entities that are instrumented by the agents5.

NEW QUESTION # 29
Which two methods are available to define JVM options for an AppDynamics Controller so that the JWM options are retained across upgrades of the Controller? (Choose two.)
- A. Pass JVM options to the Controller via java -javaagent:"options jar".
- B. Use the modifyJvmOptions utility provided by AppDynamics.
- C. Define JVM options manually in the domain. xmi file.
- D. Use the controller.sh script provided by AppDynamics.
- E. Define JVM options on the Controller Settings page of the Enterprise Console.
Answer: B,E
Explanation:
Explanation
According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the two methods that are available to define JVM options for an AppDynamics Controller so that the JVM options are retained across upgrades of the Controller are:
Use the modifyJvmOptions utility provided by AppDynamics. (A) This is a valid method because the modifyJvmOptions utility is a script that allows you to add, remove, or list the JVM options for the Controller without manually editing any files. The utility also validates the syntax and format of the JVM options and creates a backup of the original configuration. The utility is located in the
<controller_home>/bin directory and can be run on Linux or Windows platforms. The utility updates the
<controller_home>/appserver/glassfish/domains/domain1/config/domain.xml file with the specified JVM options, which are preserved during the Controller upgrade12.
Define JVM options on the Controller Settings page of the Enterprise Console. (B) This is a valid method because the Controller Settings page of the Enterprise Console is a graphical user interface that allows you to configure various settings for the Controller, including the JVM options. The Enterprise Console is a web-based application that provides a centralized way to manage the AppDynamics platform components, such as the Controller, the Events Service, and the EUM Server. The Enterprise Console also handles the Controller upgrade process and preserves the JVM options that are defined on the Controller Settings page34.
The incorrect options are:
Pass JVM options to the Controller via java -javaagent:"options jar". This is not a valid method because the java -javaagent option is used to specify the path to the AppDynamics agent jar file, not the JVM options for the Controller. The agent jar file is used to instrumentthe Java applications that are monitored by the AppDynamics platform, not the Controller itself. The agent jar file also contains the agent configuration properties, such as the Controller host, port, account name, access key, and application name. Passing JVM options to the Controller via this option will not have any effect on the Controller performance or behavior5.
Use the controller.sh script provided by AppDynamics. (D) This is not a valid method because the controller.sh script is used to start, stop, or restart the Controller, not to define the JVM options for the Controller. The controller.sh script is located in the <controller_home>/bin directory and can be run on Linux platforms. The controller.sh script does not accept any arguments or parameters for the JVM options, and does not update any configuration files with the JVM options. Using this script to define the JVM options for the Controller will not have any effect on the Controller performance or behavior6.
Define JVM options manually in the domain. xmi file. (E) This is not a valid method because the domain. xmi file is not a configuration file for the JVM options for the Controller, but a configuration file for the WebSphere Application Server. The WebSphere Application Server is a Java EE application server that can be used to host the Java applications that are monitored by the AppDynamics platform, not the Controller itself. The domain. xmi file contains the settings for the WebSphere Application Server, such as the server name, port, security, data sources, and class loaders. Defining JVM options manually in this file will not have any effect on the Controller performance or behavior, and may cause errors or conflicts with the WebSphere Application Server configuration7.

NEW QUESTION # 30
If using SSL for agent communication with an AppDynamics Controller, it is recommended that agent SSL traffic
- A. is encrypted with a 64-bit encryption key
- B. is decrypted and then encrypted again at the firewall
- C. terminates at the Controller
- D. terminates at a reverse proxy or a load balancer in front of the Controller
Answer: D
Explanation:
Explanation
AppDynamics recommends that you terminate SSL connections from agents at a reverse proxy or a load balancer in front of the Controller, rather than at the Controller itself. This improves the performance and scalability of the Controller by offloading the SSL processing to the proxy or load balancer. It also simplifies the configuration and management of SSL certificates and truststores. To enable this option, you need to configure the proxy or load balancer to accept SSL connections from agents and forward them to the Controller using HTTP. You also need to configure the agents to use SSL and point to the proxy or load balancer host and port. See Enable SSL for the Java Agent for an example. References: Agent-to-Controller Connections and Enable SSL and SSH for Database Agent Communications in the AppDynamics documentation.
NEW QUESTION # 31
Which AppDynamics Controller port(s) does the EUM Server require access to in a configuration where the EUM Server and Controller are on separate hosts (split-host configuration)?
- A. GlassFish administration port
- B. Controller database and HTTP(s) ports
- C. dedicated EUM HTTP(s) ports
- D. Controller primary HTTP{s) port
Answer: D
NEW QUESTION # 32
What are three valid reasons to use the AppDynamics REST API to retrieve metrics? (Choose three.)
- A. to calculate a new metric based on two existing metrics
- B. to archive 1-minute granularity data
- C. to evaluate health rules
- D. to retrieve health rule violations
- E. to create a custom report to be run monthly to show average node availability
- F. to create an alert using a baseline to send to an internal ticketing system
Answer: A,B,D
Explanation:
Explanation
The AppDynamics REST API to retrieve metrics allows you to get values generated for metrics by specifying the path of the metric and the time frame for the data1. Some of the valid reasons to use this API are12:
To archive 1-minute granularity data. The AppDynamics Controller stores metric data at different levels of granularity depending on the retention period. For example, it stores 1-minute granularity data for 8 days, 10-minute granularity data for 32 days, and 1-hour granularity data for 365 days. If you want to archive the 1-minute granularity data for longer than 8 days, you can use the API to retrieve and store the data in an external database or file system.
To calculate a new metric based on two existing metrics. The AppDynamics Controller provides some built-in metrics such as average response time, calls per minute, errors per minute, etc. However, you may want to calculate a new metric that is not available in the Controller, such as the ratio of errors to calls, or the percentage of slow transactions. You can use the API to retrieve the values of the existing metrics and perform the calculation using your own logic or formula.
To retrieve health rule violations. Health rules are the rules that define the performance and availability thresholds for your application components. When a health rule is violated, the AppDynamics Controller generates an event and optionally triggers a policy action. You can use the API to retrieve the list of health rule violations for a given application, time range, and severity level. This can help you monitor and troubleshoot the health of your application and take corrective actions if needed. References: Retrieve Metric Data, Health Rule API
NEW QUESTION # 33
Which two user accounts are created by the AppDynamies Controller during installation? (Choose two.)
- A. Elastic search root user
- B. OS user that will run the controller
- C. REST API user
- D. GlassFish asadmin user
- E. MySQL appd admin user
- F. Customer-specified Controller administrator account
Answer: D,F
Explanation:
Explanation
The AppDynamics Controller is a Java web application that runs on a GlassFish application server and uses a MySQL database. During the installation of the Controller, two user accounts are created by default:
The GlassFish asadmin user is the administrative user for the GlassFish server. This user has the authority to start, stop, and configure the GlassFish server and its domains. The default username for this user is admin and the default password is appdynamics. You can change the password for this user after the installation by using the asadmin command-line tool1.
The customer-specified Controller administrator account is the user account that you provide during the installation wizard. This is the account that you use to access the AppDynamics User Interface (UI) for the first time and perform various tasks such as creating applications, configuring agents, managing users and groups, and so on. You can choose any username and password for this account, but AppDynamics recommends using only ASCII characters. You can also create additional user accounts in the Controller UI after the installation2.
The other options are not user accounts that are created by the Controller installation. The Elastic search root user, the REST API user, and the MySQL appd admin user are user accounts that are used internally by the Controller components and are not exposed to the end user. The OS user that will run the controller is a user account that you need to create on the host machine before the installation, and it is not created by the Controller installation3. References: Controller Installation, Manage Users and Groups, and Update the Root User and Glassfish Admin Passwords in the AppDynamics documentation.
NEW QUESTION # 34
What are two settings that an administrator can configure from the AppDynamics Controller Admin Console?
(Choose two.)
- A. Metrics baseline calculation
- B. Retention periods
- C. Controller heap size
- D. Controller log file rotation
- E. License allocation
Answer: B,E
Explanation:
Explanation
The AppDynamics Controller Admin Console lets you configure certain global settings for the Controller, such as metric retention periods, UI notification triggers, tenancy mode, and accounts in multi-tenancy mode1.
Two of the settings that an administrator can configure from the AppDynamics Controller Admin Console are:
License allocation: This setting allows you to view and manage the license usage and availability for your Controller. You can see the total number of licenses, the number of licenses in use, the number of licenses available, and the license expiration date for each agent type. You can also allocate licenses to specific applications or accounts, and set license limits and alerts2.
Retention periods: This setting allows you to specify how long the Controller retains the metric data and the event data for your monitored applications. You can configure the retention periods for different types of data, such as minute-level metrics, hour-level metrics, day-level metrics, transaction snapshots, and events. You can also configure the data purge schedule and the data backup schedule3.

NEW QUESTION # 35
Which two preparatory tasks are required prior to installing an AppDynamics Controller on Linux? (Choose two.)
- A. Install SSH.
- B. Verify that sufficient temporary (tmp) space is available (at least 1 GB).
- C. Install JRE.
- D. Ensure that MySQL port (3388) is opened.
- E. Install libaio.
Answer: B,E
Explanation:
Explanation
Before installing an AppDynamics Controller on Linux, you need to perform some preparatory tasks to ensure the system meets the requirements and the installation runs smoothly. Two of these tasks are:
Install libaio on the host machine if it does not already have it installed. This library facilitates asynchronous I/O operations on the system, which are required by the Controller. You can use the package manager of your Linux distribution to install libaio, such as yum or apt-get. For example, on CentOS, you can run yum install libaio1.
Verify that you have enough temporary (tmp) space available on the system, at least 1 GB. The Controller installation uses the tmp space to extract and install the software components. You can check the tmp space by running df -h /tmp2. If the tmp space is insufficient, you can either free up some space by deleting unnecessary files, or specify a different temporary directory for the installation by passing the -Djava.io.tmpdir parameter to the installer3.
Other preparatory tasks include verifying the user account permissions, configuring the virus scanners, installing the netstat network utility, and setting the file descriptor limit2. References: Prepare Linux for the Controller, Install the Controller on Linux, and [Controller System Requirements] in the AppDynamics documentation.
NEW QUESTION # 36
What are two reasons that would require an administrator to install the Events Service cluster manually?
(Choose two.)
- A. Security concerns with passwordless SSH
- B. Installation on Windows
- C. Security requirements to install using a non-root user account
- D. Installation on SUSE Linux
Answer: A,C
Explanation:
Explanation
According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the two reasons that would require an administrator to install the Events Service cluster manually are:
Security concerns with passwordless SSH (B): This is a valid reason because the automated installation of the Events Service cluster requires passwordless SSH access to the target hosts. Passwordless SSH allows the Enterprise Console to execute commands on the remote hosts without prompting for a password. However, some organizations may have security policies that prohibit passwordless SSH access, as it may pose a risk of unauthorized access or malicious attacks. In such cases, the administrator can install the Events Service cluster manually, by following the steps described in the Manual Installation of the Events Service Cluster document1.
Security requirements to install using a non-root user account : This is a valid reason because the automated installation of the Events Service cluster requires root privileges on the target hosts. Root privileges allow the Enterprise Console to create directories, change permissions, and install packages on the remote hosts. However, some organizations may have security policies that restrict root access, as it may pose a risk of accidental or intentional damage to the system. In such cases, the administrator can install the Events Service cluster manually, by following the steps described in the Manual Installation of the Events Service Cluster document1. The administrator can use a non-root user account that has sudo privileges to perform the manual installation.
The incorrect options are:
Installation on SUSE Linux (A): This is not a valid reason for manual installation, because the automated installation of the Events Service cluster supports SUSE Linux as one of the compatible operating systems. The Enterprise Console can install the Events Service cluster on SUSE Linux hosts using the automated installation process, as long as the hosts meet the prerequisites described in the Events Service Requirements document2.
Installation on Windows (D): This is not a valid reason for manual installation, because the Events Service cluster does not support Windows as an operating system. The Events Service cluster can only run on Linux hosts, as it is based on Apache Cassandra, which is a Linux-based distributed database. The Events Service cluster cannot be installed on Windows hosts, either manually or automatically2.

NEW QUESTION # 37
The application server was restarted after an upgrade. What are two valid ways to confirm that the upgraded Java Agent is running successfully? (Choose two.)
- A. Verify the Java Agent Version metric for that node in the Metric Browser.
- B. Verify that the application log contains a message indicating success.
- C. Verify that the node within the Controller Ul indicates the app agent is reporting.
- D. Verify that the Java Agent log contains a message indicating the agent started successfully.
Answer: A,C
Explanation:
Explanation
According to the Cisco AppDynamics Professional Implementer (CAPI) documents, the two valid ways to confirm that the upgraded Java Agent is running successfully are:
Verify that the node within the Controller UI indicates the app agent is reporting. (B) This is a valid way because the Controller UI is a web-based application that allows users to monitor and manage the performance of the applications, tiers, nodes, and other entities that are instrumented by the AppDynamics agents. The Controller UI displays the status of the nodes within each tier, and indicates whether the app agent is reporting or not. If the app agent is reporting, the node icon is green and shows the agent version. If the app agent is not reporting, the node icon is gray and shows the last time the agent reported. The user can also hover over the node icon to see more details, such as the agent type, the agent version,the agent runtime directory, and the agent properties file. The user can verify that the upgraded Java Agent is running successfully by checking that the node icon is green and shows the latest agent version12.
Verify the Java Agent Version metric for that node in the Metric Browser. This is a valid way because the Metric Browser is a feature of the Controller UI that allows users to view and analyze the metrics collected by the AppDynamics agents. The Metric Browser displays the metrics in a hierarchical tree structure, where each node represents a metric category, a metric name, or a metric value. The user can expand or collapse the nodes, and select or deselect the metrics to view them in a chart. The user can also apply filters, time ranges, baselines, and other options to customize the chart. The user can verify that the upgraded Java Agent is running successfully by navigating to the Java Agent Version metric for that node in the Metric Browser. The Java Agent Version metric shows the version number of the Java Agent that is running on the node. The user can compare the metric value with the expected agent version, and check that the metric is updated after the upgrade34.
The incorrect options are:
Verify that the application log contains a message indicating success. (A) This is not a valid way because the application log does not contain any message indicating the success of the Java Agent upgrade. The application log is a file that records the events and messages that occur in the application server, such as the startup, shutdown, errors, warnings, and debug information. The application log does not record the events and messages that occur in the Java Agent, such as the installation, upgrade, configuration, or reporting. The Java Agent has its own log file, which is located in the
<agent_home>/logs directory, and which contains the messages indicating the success or failure of the Java Agent upgrade .
Verify that the Java Agent log contains a message indicating the agent started successfully. (D) This is not a valid way because the Java Agent log does not contain any message indicating the agent started successfully after the upgrade. The Java Agent log is a file that records the events and messages that occur in the Java Agent, such as the installation, upgrade, configuration, or reporting. The Java Agent log contains a message indicating the agent started successfully when the application server is started, not when the Java Agent is upgraded. The Java Agent log does not contain any message indicating the success or failure of the Java Agent upgrade. The Java Agent log is located in the <agent_home>/logs directory, and the message indicating the agent started successfully is "Agent Startup Complete" .

NEW QUESTION # 38
Which implementation mode should be used when deploying an EUM Server with reverse proxy from a security and performance standpoint in a production environment?
- A. Install the EUM Server on a separate host from the Controller, in front of the reverse proxy.
- B. Install the EUM Server on a separate host from the Controller, behind the reverse proxy.
- C. Install the EUM Server on the same host as the Controller, behind the reverse proxy.
- D. Install the EUM Server on the same host as the Controller, in front of the reverse proxy.
Answer: B
Explanation:
Explanation
The EUM Server is the on-premises version of the EUM Cloud that receives, processes, and stores data from EUM agents. For production installation, AppDynamics recommends that the EUM Server and the Controller sit on different hosts, and the EUM Server hosts its own MySQL instance. This improves the scalability and performance of both components. Moreover, AppDynamics strongly recommends that SSL traffic from agents to the EUM Server is terminated at a reverse proxy that sits in front of the EUM Server in the network path, and forwards connections to the EUM Server using HTTP. This relieves the SSL processing load from the EUM Server, simplifies the certificate management, and enhances the security by isolating the EUM Server from the external Internet. Therefore, the best implementation mode for deploying an EUM Server with reverse proxy in a production environment is option D.
