VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 51

A customer defines a requirement to minimize the vMotion migration time during a maintenance period. The servers being used are equipped with eight 1 GbE network adapters.
Per the defined logical network configuration, there are two network adapters each used for:
✑ Management traffic
✑ vMotion traffic
✑ iSCSI traffic
✑ Virtual machine traffic
Which design decision should the architect make to meet the customer requirement?

Answer options

• A. Use Network I/O Control to define a reservation for vMotion traffic.
• B. Implement Multi-NIC vMotion by adding additional vMotion VMkernels.
• C. Configure a dedicated TCP/IP stack for vMotion traffic.
• D. Combine vMotion and Management traffic to make use of four adapters.

Correct answer: B

Explanation

The correct answer is B because implementing Multi-NIC vMotion allows for increased bandwidth and faster migration times by using multiple network interfaces. Options A, C, and D do not effectively increase the migration speed; they either prioritize traffic without increasing throughput, isolate traffic without leveraging multiple paths, or combine traffic types which could lead to contention.
