Which two statements are true about the FGCP protocol? (Choose two.)

The FortiGate Cluster Protocol (FGCP) is the proprietary High Availability (HA) protocol used by FortiGate devices. A primary function of FGCP is to manage the cluster and elect one unit as the primary (or master) device. This election is based on factors like monitored interfaces, device uptime, and configured priority. All FGCP communication, which includes heartbeat packets, synchronization data, and election messages, is transmitted exclusively over the dedicated heartbeat link(s). This isolates HA traffic from regular data traffic, ensuring the stability and reliability of the cluster.

B. FGCP is fully supported and used when a FortiGate cluster is operating in either transparent mode or NAT/route mode.

D. FGCP operates only within a single HA group, defined by a common Group ID and password, to discover and communicate with members of the same cluster.

"How FGCP elects the primary unit".

"The FortiGate Cluster Protocol (FGCP) elects a primary FortiGate unit that is responsible for processing all traffic and for synchronizing the cluster." (Supports Answer A)

"Basic HA configuration".

"All FortiGates in the cluster must have the same Group ID." (This implies the scope of FGCP discovery is limited to the configured group

refuting Option D).
