What is a characteristic of the FortiManager high availability (HA) feature?

The characteristic of the FortiManager high availability (HA) feature is that the primary unit synchronizes all configuration revisions with the secondary units. This ensures that all devices in the HA cluster are up-to-date with the same configurations, providing redundancy and failover capabilities.

Options A, C, and D are incorrect because:

Arefers to a specific port number (5199), but FortiManager does not specifically use TCP port 5199 to update managed devices when a secondary unit is removed.

Cis incorrect as secondary units do not necessarily have to be in the same network as the primary unit; they just need to be able to communicate with each other.

Dis incorrect because HA upgrades can be automated and do not require manual upgrading, starting with the primary unit.
