EMC Virtualized Data Center and Cloud Infrastructure Design Specialist Sample Questions:

1. As part of a VDC design, you configured a number of hypervisor clusters that require a nonroutable network to accommodate data transfers for online VM migrations and cluster heartbeats. However, some of the clusters contain sensitive data that should not be accessible by hypervisors in any other cluster. The design recommends using Private VLANs to isolate each cluster's private network traffic.
The network administrator has created a Primary VLAN, and asks you how the Private VLANs should be configured. How should you instruct the network administrator to proceed?

A) Configure an Isolated Private VLAN for each cluster.
B) Configure a Community Private VLAN for each cluster.
C) Configure an Isolated Private VLAN for each cluster, and configure the gateway port in the Primary VLAN.
D) Configure a Community Private VLAN for each cluster, and configure the gateway port in the Primary VLAN.

2. Your customer is primarily concerned with asset discovery and a reconciled view of all infrastructure components and the dependencies between them.
Which type of architecture would you recommend?

A) Change management system
B) Asset management system
C) CMDB
D) Federated CMDB

3. What is a key business driver for automation in the virtualized data center?

A) Change management policy
B) Technology integration
C) Service-level agreements
D) Service metric reporting

4. Refer to the exhibit.

You are expanding the compute layer of a VDC, and need to add more access layer switches to provide connectivity to the hypervisors. However, there are no available ports on the two aggregation layer switches to accommodate the uplink connections from the new access layer switches, and there is no available funding to purchase additional aggregation layer switches. The active uplinks are operating at 95% of capacity.
What can be done to expand the access layer and not impact the performance of the existing environment?

A) Aggregate the aggregation layer switches into a virtual switch.
Reduce the number of uplink connections from each access layer switch by 50%.
B) Aggregate the access layer switches into a virtual switch.
Reduce the number of uplink connections to each aggregation layer switch by 50%.
C) Aggregate the datacenter core switches.
Reduce the number of uplink connections from each aggregation layer switch by 50%.
D) Aggregate the datacenter core switches.
Reduce the number of uplink connections from each access layer switch by 50%.

5. When selecting multipathing software, which requirement would favor choosing PowerPath/VE instead of native multipathing?

A) Tight integration with, and optimization for, specific models of storage arrays
B) Support for active/passive storage arrays
C) A distinct set of base features for each supported hypervisor
D) A choice of several path selection algorithms for each supported storage array
