NSE4 Question #317: Real Exam Question with Answer & Explanation

Question

View the exhibit. What is the effect of the Disconnect Cluster Member operation as shown in the exhibit? (Choose two.)

Options

• AThe HA mode changes to standalone.
• BThe firewall policies are deleted on the disconnected member.
• CThe system hostname is set to the FortiGate serial number.
• DThe port3 is configured with an IP address for management access.

Explanation

Disconnecting a cluster member removes it from the High Availability (HA) cluster, causing it to revert to standalone mode and configure a default management IP on a specific port.

Common mistakes.

• B. Disconnecting a member from an HA cluster does not delete its firewall policies; instead, it retains its last synchronized configuration, including policies.
• C. While the hostname might be derived from the serial number by default, the "Disconnect Cluster Member" operation itself does not explicitly set the hostname; it primarily affects HA and interface configuration.
