EMC Virtualized Data Center and Cloud Infrastructure Design Specialist Sample Questions:
1. You are meeting with the CIO to discuss your VDC design. They the amount of capital that is being invested in iSCSI adapters. They state that, because of the number of adapters required, it is more cost-effective to purchase 10 Gigabit Ethernet NICs and use the integrated hypervisor software stack.
How should you justify the increased cost of the iSCSI Adapters?
A) iSCSI adapters can encrypt iSCSI frames, preventing unauthorized access to the data. The hypervisor software stack cannot encrypt iSCSI frames, leaving the data vulnerable.
B) iSCSI adapters can use Jumbo Frames, providing improved performance for storage traffic. The hypervisor software stack cannot use Jumbo Frames, resulting in poorer performance.
C) Using NICs and the software stack will require additional NICs for each hypervisor to deliver the same throughput. To obtain the additional PCIe slots for the NICs, larger form-factor servers will be required, increasing hardware costs.
D) Using NICs and the software stack will increase CPU load on each hypervisor, requiring more hypervisors to deliver the same performance levels. This will result in additional hardware and licensing costs.
2. An application development team of a stock trading firm requires a very complex testing environment that has to be re-deployed with each code revision. It usually takes a system administrator at least a day to rebuild the environment using imaging software.
How would virtualization benefit this firm?
A) Measured service
B) On-demand self-service
C) Resource pooling
D) Simplified provisioning
3. 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) Application consistency
B) Eventual consistency
C) Crash consistency
D) Full consistency
4. What is a benefit of client-side application virtualization?
A) The same management tools used for standard application management can be used to manage virtualized client-side applications
B) All applications can be virtualized, providing flexibility and management control of client-side applications
C) Reduced overall complexity in the application and desktop environment is achieved
D) Simplification and standardization of patch management is achieved
5. What are two important Privacy by Design in Practice principles of an ILM strategy?
A) Minimizing the data collected and role separation
