NEW QUESTION # 26
A Network Operator is troubleshooting a connectivity issue where a host (10.10.10.50) cannot communicate with its default gateway (10.10.10.1). When the operator checks the ARP table on the gateway, the entry for 10.10.10.50 is "Incomplete".
What is the function of the Address Resolution Protocol (ARP) in this scenario?
- A. To translate the private IP address of the host to a public IP address.
- B. To determine the Layer 3 route the host should use to reach the gateway.
- C. To assign a dynamic IP address to the host.
- D. To discover the MAC address of the host associated with the IP address 10.10.10.50.
Answer: D
NEW QUESTION # 27
A Network Operator has just configured a new LACP-based Link Aggregation Group (LAG) between an access switch and a core switch. The LAG, `lag 1`, is composed of ports 1/1/47 and
1/1/48. The operator needs to validate that both physical links have successfully joined the aggregation and that LACP negotiation is complete.
The operator needs to answer the following questions:
* Is LACP enabled on the LAG?
* Are both member ports (1/1/47 and 1/1/48) successfully bundled?
* What is the operational state of the local and partner ports?
Which of the following validation commands provides the most direct and detailed output to answer all these questions?
- A. `show running-config interface lag 1`
- B. `show interface lag 1`
- C. `show mac-address-table interface lag 1`
- D. `show lacp interfaces`
Answer: D
NEW QUESTION # 28
A Network Technician is configuring an access layer switch (ALS) to connect to a core switch.
The connection uses two physical links that need to be bundled into a Link Aggregation Group (LAG) for increased bandwidth and redundancy. The LAG will function as a VLAN trunk to carry both Staff (VLAN 100) and Guest (VLAN 200) traffic. The technician must also enable RSTP for loop prevention.
Initial State:
* The switch is in its factory default state, connected via the console.
* The physical links are on ports 1/1/47 and 1/1/48.
Required Configuration:
* Create VLAN 100 and VLAN 200.
* Enable Rapid Spanning Tree Protocol (RSTP).
* Create LAG interface `lag 1`.
* Configure `lag 1` to use LACP (active mode).
* Add ports 1/1/47 and 1/1/48 to `lag 1`.
* Configure `lag 1` as a VLAN trunk, allowing VLANs 100 and 200.
* Enable the physical ports and the LAG interface.
Which configuration set correctly implements all the specified Layer 2 requirements?
- A. spanning-tree mode mstp
vlan 100,200
interface lag 1
no shutdown
vlan access 100
vlan trunk allowed 200
interface 1/1/47-1/1/48
no shutdown
lag 1 - B. spanning-tree
vlan 100,200
interface 1/1/47-1/1/48
no shutdown
lacp group 1 mode active
interface lag 1
no shutdown
vlan trunk allowed 100,200 - C. vlan 100
vlan 200
interface lag 1
no shutdown
vlan trunk allowed 100,200
interface 1/1/47-1/1/48
no shutdown
lag 1 - D. spanning-tree mode rstp
vlan 100,200
interface lag 1
no shutdown
vlan trunk allowed 100,200
lacp mode active
interface 1/1/47-1/1/48

NEW QUESTION # 31
A customer has configured a CX 6200F VSF stack already in use. You are given the following information on the setup:
What steps are required to add a new member to the solution?
- A. A link between members 1 and 3 needs to be disconnected.
- B. The VSF link 2 on member 1 must be reconfigured to support new members.
- C. The new member needs to be pre-provisioned as a standby.
- D. The topology of the configuration needs to be set to chain.
Answer: C

To add a new member to an existing CX 6200F VSF stack, the new switch must be pre- provisioned as a standby member. This ensures it can correctly join the existing VSF topology and integrate into the stack without disrupting current operations.
NEW QUESTION # 32
A Solutions Architect is investigating a complex, intermittent issue in a multi-tier campus network.
Users are reporting that access to a critical internal application server (10.100.1.50) is periodically slow or times out. The network consists of multiple AOS-CX switches. The architect suspects a routing problem or a silent packet drop at one of the intermediate Layer 3 hops. The goal is to non-disruptively trace the path and identify the point of failure.
Which general troubleshooting tool should the architect use from the user's gateway switch to identify every Layer 3 hop on the path to the application server and measure the latency to each hop?
- A. `show arp`
- B. `traceroute 10.100.1.50`
- C. `show ip route`
- D. `ping 10.100.1.50`
Answer: B
NEW QUESTION # 33
A Network Technician is troubleshooting a connectivity issue where a user on port 1/1/10 cannot reach the internet. The technician needs to verify the user's Layer 1 and Layer 2 connectivity and see if the switch is learning the user's MAC address.

* Is the port physically connected and up?
* What VLAN is the port assigned to?
* Is the switch learning any MAC addresses on that port?
* What is the speed and duplex of the link?
Which of the following validation commands provides the most comprehensive output to answer all these questions at once?
- A. `show mac-address-table interface 1/1/10`
- B. `show vlan port 1/1/10`
- C. `show running-config interface 1/1/10`
- D. `show interface 1/1/10`
Answer: D
NEW QUESTION # 34
A network administrator is performing routine administrative tasks on an HPE Aruba Networking CX 6400 switch stack. They need to back up the current running configuration to a remote SFTP server for archival purposes. The administrator wants to follow best practices for file management.
Review the following command:
copy running-config sftp://[email protected]/configs/CX6400_backup.cfg vrf mgmt Which statement accurately describes the outcome of executing this command?
- A. The running configuration will be securely copied to the specified directory on the SFTP server using the management VRF.
- B. The command copies the startup configuration, not the running configuration, to the SFTP server.
- C. The command will fail because the `vrf mgmt` parameter is only used for TFTP transfers.
- D. The configuration will be copied in plain text, as SFTP only encrypts the authentication, not the data transfer itself.
Answer: A
NEW QUESTION # 35

NEW QUESTION # 36
Which statement is true when creating VLANs on an HPE Aruba Networking CX switch?
- A. A VLAN range can be created with a syntax of:
vlan 100-110 - B. A newly created VLAN needs to be enabled with a command:
vlan 100
enable - C. A newly created VLAN needs to be enabled with a command:
vlan 100
no shutdown - D. A VLAN range can be created with a syntax of:
vlan 100:110

Users report poor performance when uploading files to their document management server in the same subnet. You suspect packet loss is causing the problem. Which tool in HPE Aruba Networking Central can you use to confirm this?
- A. Network Check - Traceroute
- B. Device Check - Cable Test
- C. Network Check - Ping
- D. Commands - show interface error-statistics
Answer: C
Explanation:
Ping can be used to measure packet loss by sending multiple echo requests and analyzing lost responses, which helps confirm whether packet loss is occurring between clients and the server within the same subnet.

- A. The link will successfully negotiate to 100Mbps, full-duplex.
- B. The switch will operate at 1000Mbps, and the server will drop most packets.
- C. The link will operate at 100Mbps, but performance will be extremely poor due to collisions and errors.
- D. The link will fail to come up, and no traffic will pass.
Answer: C
NEW QUESTION # 40
When multiple routes exist to the same destination, which would be installed in the routing table?
- A. Static route.
- B. Lowest administrative distance.
- C. Highest administrative distance.
- D. Default route.
Answer: B
