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

1. You are using virtual (thin) provisioning to reduce the amount of physical storage that is initially required for an implementation.
On the storage array, you configure a pool that contains 10 TB of physical storage and then define several LUNs that total 50 TB. These LUNs are presented to several hypervisor clusters. Virtual Machines are subsequently created using a thick format for the virtual hard disks.
What is the maximum capacity that can be allocated for VM hard disks in this configuration?

A) 100 TB
B) 60 TB
C) 10 TB
D) 50 TB

2. A hypervisor running virtual servers fails with an unrecoverable error and at virtual server are restarted on another hypervisor. When the application restarts, some data has been lost.
Which type of consistency does this situation represent?

A) Eventual consistency
B) Full consistency
C) Application consistency
D) Crash consistency

3. Which is a poor candidate for migration to a VDC?

A) An enterprise-wide manufacturing application
B) An application requiring data isolation
C) An application with web-scale characteristics
D) An n-tier application that uses an open-source database

What should the administrator implement to provide this new subnet for the application servers in the least amount of time?

A) Add network cards to the hypervisor host
B) Add virtual switch to the hypervisor host
C) Add a new port group with an individual VLAN
D) Add ports to an existing port group

5. A large enterprise has virtualized heavily in their data center. All virtual machines in the enterprise are built from standardized baseline templates. Based on these image templates, they have set configuration best practices and implementation workflows.
Recently, the company has started to see performance issues on several production-critical virtual guests. In responding to the performance issues, the cause was found to be incorrectly configured vNIC parameters in the virtual guests.
Which service should be implemented to identify deviations in the deployed servers from the baseline templates, and to remediate any such deviations?

A) CMDB automation
B) Change management reporting
C) Policy-driven configuration management
