Configure vCenter Server High Availability in Different Data Centers

B.

The correct answer is B. Network latency between the nodes must be less than 10 milliseconds.

Explanation:

vCenter Server High Availability (vCenter HA) is a feature that ensures high availability and business continuity for vCenter Server. In a vCenter HA configuration, there are three vCenter Server instances: one active node and two passive nodes. The passive nodes are always in sync with the active node, and in the event of a failure, one of the passive nodes takes over as the active node. The passive nodes are also known as secondary nodes.

For a vCenter HA configuration where each node is located in a different data center, it is important to ensure that the network latency between the nodes is less than 10 milliseconds. This is because the vCenter HA nodes communicate with each other over the network, and a high network latency can cause synchronization issues between the nodes. If the network latency is too high, vCenter HA may not function correctly, and failover may not occur in the event of a failure.

Option A is incorrect because the number of network adapters is not a requirement for configuring vCenter HA.

Option C is incorrect because the nodes do not need to be located on a vSAN datastore. However, it is recommended to use a shared storage solution for the vCenter HA configuration.

Option D is incorrect because vCenter HA is a feature included with the vCenter Server license, and a separate license is not required for each node in the configuration.
