EMC Virtualized Data Center and Cloud Infrastructure Design Specialist Sample Questions:
Question 1
Which is a valid method for modifying an application environment to support more clients and increased data throughput?
A. Vertically scale by adding more nodes to support the application
B. Migrate the application from NL SAS to SAS storage
C. Horizontally scale by increasing system resources on the same number of nodes
D. Migrate the application from SSD to SAS storage
Question 2
You are designing a VDC that uses converged networking to support both LAN and SAN traffic. FCoE is used exclusively for storage access. The access and aggregation layer switches that have been chosen support both 10 and 40 Gigabit Ethernet and Data Center Bridging.
You have determined that the traffic between the access layer and aggregation layer switches is:
-
Average SAN (FCoE) - 60 Gb/s
-
Average LAN (Ethernet) - 100 Gb/s
-
Burst SAN (FCoE) - 80 Gb/s
-
Burst LAN (Ethernet) - 130 GB/s
Performance cannot be degraded due to a failure of a single switch.
Which port configuration would support the average traffic between the access and aggregation layer switches?
A. Three 40 Gb/s ports and six 10 Gb/s ports
B. Four 40 Gb/s ports
C. Four 40 Gb/s ports and eight 10 Gb/s ports
D. Three 40 Gb/s ports and four 10 Gb/s ports
Question 3
Which mode of IPSec encrypts the entire IP packet?
A. Transparent
B. Trusted
C. Tunnel
D. Transport
Question 4
As part of a VDC deployment, you are examining the existing storage configurations. On one storage system, you discover over fifty storage pools. The pools contain a single type of drive (SSD, SAS or NL SAS), but many of them contain only a few drives and share the same RAID configuration. The Storage Administrator admits that they have been creating separate pools for each application because they did not want the applications contending for the disks.
As part of the design, you propose to consolidate the existing pools into larger pools of mixed drive types and RAID configurations.
What technology will you need to implement to utilize the new pool design?
A. Caching Tier
B. Storage Tiering
C. Virtual Provisioning
D. Storage Virtualization
Question 5
What is a feature of the Cisco Unified Computing System (UCS)?
A. Server identity pools
B. Layer 3 routing optimization
C. Fabric reconfiguration services
D. CMDB maintenance utilities
