VMware Exam 5V0-21.21 Topic 3 Question 60 Discussion

Actual exam question for VMware's 5V0-21.21 exam
Question #: 60
Topic #: 3
[All 5V0-21.21 Questions]

As a part of a network hardware refresh project, all the network switches have been replaced with a newer, high-performance model. After the replacement, the company users started experiencing slowness on the applications hosted on their vSAN-backed VMs.

The vSAN administrator checked the vSAN Network Health status and noticed that the "Hosts large ping test" has failed.

What could be the cause of this performance degradation issue?

Ah, the old 'Hosts large ping test' failure. Classic vSAN performance issue. I bet the answer is in the VMware Compatibility Guide somewhere.

Aha! I knew it was the vDS switch. That's where all the magic happens, right? Now I just need to remember what the heck 'MTU 9K' means.

Wait, so we're supposed to configure the MTU on the ToR switch? I thought that was just for the vSAN vMKernel ports. Looks like I need to brush up on my vSAN networking knowledge.

I agree with Carey. If the MTU 9K is not configured on the vSAN vMKernel ports, it could definitely cause performance degradation.

I think the cause could be option A) MTU 9K is not configured on the hosts vSAN vMKernel ports.

Hmm, I bet the network admin was too busy playing ping pong to configure the MTU on the switches. Gotta keep those packets flowing, am I right?

Yeah, that could definitely cause performance degradation. They should check that first.

Maybe the MTU 9K is not configured on the hosts vSAN vMKernel ports.

Maybe the issue is with the MTU not being configured on the hosts vSAN vMKernel ports.
