Question
Which are four attributes of the Active vCenter HA node? (Choose four.)
Options
- AIt runs the active vCenter Server Appliance instance.
- BIt provides a quorum to protect against a split-brain situations.
- CIt uses a public IP address for the management interface.
- Dit constantly replicates vPostgres data with the Witness node.
- EIt uses the vCenter HA network for replication of data.
- FIt uses the vCenter HA network to communicate with the Witness node.
Explanation
The Active vCenter HA node runs the live vCenter Server instance, holds the management IP, and uses the dedicated HA network for both data replication to the Passive node and heartbeat communication with the Witness node.
Common mistakes.
- B. Providing quorum to prevent split-brain scenarios is the role of the Witness node, not the Active node - the Witness casts the deciding vote when the Active and Passive nodes cannot communicate with each other.
- D. vPostgres data is replicated between the Active node and the Passive node only - the Witness node stores no database data and participates only in quorum/heartbeat functions.
