VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 61

An architect is tasked with designing a new VMware software-defined data center (SDDC) using VMware vSAN. The architect uses a storage assessment tool to determine the storage requirements for the new vSAN cluster. The new SDDC is going to be deployed into the existing data center and must be connected to a shared core network switch.
The architect decides to use vSAN ReadyNodes with the following configuration:
✑ Two disk groups with:
- Write Intensive NVMe 800 GB drive for cache
- Four 3.84 TB Mixed Use NVMe for capacity
✑ Four 10 GbE ports
Which element represents a risk that should be included in this design?

Answer options

• A. The number of 10 GbE capable ports in the vSAN ReadyNode
• B. The use of vSAN ReadyNodes
• C. The existing network is 10 GbE capable
• D. The use of NVMe drives for cache and capacity

Correct answer: C

Explanation

The correct answer is C because the existing network's capability to support 10 GbE may not adequately handle the increased traffic from the new SDDC, posing a risk of bottlenecks. Options A, B, and D do not represent inherent risks in the design as they pertain to the components being used rather than the overall network compatibility.
