Question
Two devices are in an HA cluster, the device hostnames are STUDENT and REMOTE. Exhibit A shows the command output of diagnose sys session stat for the STUDENT device. Exhibit B shows the command output of diagnose sys session stat for the REMOTE device. Exhibit A:

Given the information provided in the exhibits, which of the following statements are correct? (Choose two.)
Exhibits
Options
- ASTUDENT is likely to be the master device.
- BSession-pickup is likely to be enabled.
- CThe cluster mode is active-passive.
- DThere is not enough information to determine the cluster mode.

Why each option
This question asks to interpret FortiGate `diagnose sys session stat` output from two HA cluster members to determine their roles and cluster state.
The STUDENT device has 250 active sessions while the REMOTE device has 0 sessions, indicating that STUDENT is actively processing traffic and therefore is likely the master device in an active-passive setup.
While the question implies an HA cluster, the `diagnose sys session stat` output alone does not provide information about whether session-pickup is enabled or disabled.
Although STUDENT having sessions and REMOTE having none suggests active-passive, the `diagnose sys session stat` command output itself does not definitively state the cluster mode, as it only reports session counts.
The `diagnose sys session stat` output shows only current and maximum session counts for each device; it does not provide explicit information about the configured HA cluster mode (e.g., active-passive, active-active). Without additional commands or configuration details, the cluster mode cannot be definitively determined from this output alone.
