Show Suggested Answer Hide Answer
Suggested Answer: A, D

When configuring vCenter High Availability (HA), two of the requirements for the active, passive, and witness nodes are that network latency must be less than 10 milliseconds, which ensures reliable communication between them; and they must have a minimum of a 1 Gbps network adapter, which provides sufficient bandwidth for data replication.

D makes sense too. 1 Gbps is a standard for HA setups.

Wait, E) Network latency must be more than 10 milliseconds? That can't be right!

I thought they could work with 1 Gbps, isn't that enough?

I’m pretty sure the latency must be less than 10 milliseconds, but I’m confused about the network adapter requirements. Was it 1 Gbps or 10 Gbps?

I feel like the WAN support was a requirement too, but I can't remember if it was specifically for the witness node or all of them.

I think they mentioned needing a minimum of a 1 Gbps adapter in practice questions, but I can't recall if that was for all nodes or just the active one.

I remember something about network latency needing to be under 10 milliseconds, but I'm not sure if it's both nodes or just one.
