VMware vSphere 6.5 Foundations (VCP6.5-DCV) — Question 37

A vSphere Administrator notices that sometimes they receive poor network throughput for multiple port groups that reside on a vSwitch with multiple physical uplinks (vmnics). The configuration on the ESXi host is identical to other hosts that are working properly in the same cluster.
What should be done next?

Answer options

• A. Restart Management agents in ESXi Using Direct Console User Interface (DCUI).
• B. Add additional port groups to the vSwitch.
• C. Alter the failover order of the vmnics until a bad vmnic is found.
• D. Add additional resources to the virtual machines that are powered on.

Correct answer: A

Explanation

Restarting the Management agents in ESXi using the DCUI can resolve issues with network throughput as it refreshes the networking stack and can correct misconfigurations. Adding port groups or resources won't address the underlying network performance issue, and altering the failover order may only temporarily mask the problem without identifying the root cause.
