Topic #: 1
[All DES-2T13 Questions]

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.

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.
You are designing a private cloud to use VLANs to support compute-to-compute connectivity. The IT team has added a requirement to simplify the configuration management within the infrastructure.
What is a limitation related to VLANs for this requirement?

  • 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

Correction Configuration Management: After configuring VLANs, adding new VLANs to the environment requires configuration changes throughout the stack. Although it is possible to automate this process, it becomes hard to support and is not a fast process in a large infrastructure. Unless you reconfigure a virtual machine instance, mobility of that instance is limited to hosts that have access to the same VLANs

Limited Networks: Though a VLAN identifier is a 4-byte tag field in the original Ethernet frame, but the actual VLAN address portion in it is 12 bits. Because of this limitation of address bits defined in the 802.1Q standard, VLANs can only support up to 4094 virtual networks. Since, cloud requires many network segments to support various services or tenants, this number could be a limiting factor Correct B
