Availability reporting, risk level, regulations, security requirements D. Risk level, assessment date, regulations, security requirements

Correct Answer: D

Question 4

As part of a VDC design, you configured a number of virtual machine OS clusters. Each cluster must have a non-routable network to accommodate system heartbeats. However, some of the clusters house sensitive data that should not be accessible by any other cluster. For fault tolerance purposes, the cluster nodes will never be hosted on the same hypervisor.
How should you instruct the administrator to configure the Private VLANs?

A. Configure the Primary and Isolated VLANs on both the hypervisor virtual switches and access layer switches. B. Configure the Primary and Community VLANs on the hypervisor virtual switches. C. Configure the Primary and Community VLANs on both the hypervisor virtual switches and access layer switches. D. Configure the Primary and Isolated VLANs on the hypervisor virtual switches.

Correct Answer: C

Question 5

A small college asks you to design a VDC that will span four data centers located within a campus environment. They want to have the VLANs stretched across all four locations. They also require stretched clusters spanning pairs of data centers.
Which distance networking technology would most cost effectively address their requirements?

A. CWDM B. Dark Fiber C. DWDM D. MPLS

Correct Answer: B

Question 6

You have decided to pursue a "scale-up" approach instead of a "scale-out" approach to storage.
What is the fundamental tradeoff that you have made?

A. Simplicity of management versus improved scalability B. Higher application throughput versus degraded response time C. Ease of storage tiering versus poor resource utilization D. Improved availability versus limited scalability

Correct Answer: A

Question 7

What are the two common factors that drive a company to institute a company-wide compliance program?
