VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 36

An architect is creating a network design for a new vSphere environment.
Based on customer requirements, the environment must support the following types of traffic:
✑ Management
✑ vMotion
✑ vSAN
✑ Fault Tolerance
✑ Virtual machine traffic, which cannot be impacted by other types of traffic
Which design recommendation can the architect make for a resilient infrastructure with vSphere network service tiering?

Answer options

• A. Use different logical networks to ensure traffic is isolated with separate VLANs
• B. Use Network I/O Control and ensure appropriate share value is defined for different types of traffic giving priority to the virtual machines traffic
• C. Use two dedicated virtual switches with a single adapter each, dedicating one virtual switch for Management, vMotion, vSAN and Fault Tolerance traffic, and the second one for virtual machine traffic
• D. Use a NIC teaming policy based on the physical NIC load

Correct answer: B

Explanation

Option B is correct because Network I/O Control allows for prioritization of traffic types, ensuring that virtual machine traffic has the highest priority and is not affected by other traffic. Option A does not ensure prioritization, merely isolation, while Option C may not provide the necessary prioritization for traffic types. Option D focuses on balancing the physical NIC load rather than managing the quality of service for different traffic types.
