What two statements are true about VMware Aria Operations Manager high availability (HA)?

To enable HA, you must deploy at least 3 data nodes, plus the primary node.

If the primary node fails, the replica node can take over all functions of the primary node.

With HA. data stored in the primary node is partially backed up on the replica node.

Data collection must be restarted from the administrative interface when the primary node fails.

Upon failure of the primary node, failoverto the replica is automatic.
