SPECIAL INSTRUCTIONS REMINDER

The remaining questions are associated with two cases.

Each case has an introductory, descriptive passage (case text) that describes background information and requirements for a specific cloud based design. And each case has a set of six related, randomized questions. You will need to read the case text in order to answer the related questions correctly.

Given that there are two cases with six scored questions each, the total number of case-based scored questions is 12.

When you display each questions you can easily review the related case text in a pop-up window by clicking on the “Case” icon (shown below)

Case 4

Refer to the exhibit.

Question # 8

Your company is currently using a traditional SAN storage network. The server infrastructure is partially virtualized. There is a public cloud in place that is used to test development and application migration to cloud.

Business requirements:

    Consolidate the network, storage, and compute resources

    Simplify network management and storage provisioning

    Maintain application performance

    Need to share resources to reduce cost and improve efficiency

Other considerations:

    Monitoring of protection SLAs

    All transactions must be logged for auditing review

    Users are validated using internal credentials

Refer to Case 4.

What is a limitation related to VLANs for this requirement?

Options:

A.

VLANs require separate infrastructure and management traffic trunks


B.

VLANs can only support up to 4094 virtual networks


C.

Adding a new VLAN requires configuration changes throughput the stack


D.

Converged infrastructure limits which NICs can separate network traffic types
