NSE 4 – FortiGate 6.0 — Question 89

An administrator observes that the port1 interface cannot be configured with an IP address. What can be the reasons for that? (Choose three.)

Answer options

• A. The interface has been configured for one-arm sniffer.
• B. The interface is a member of a virtual wire pair.
• C. The operation mode is transparent.
• D. The interface is a member of a zone.
• E. Captive portal is enabled in the interface.

Correct answer: A, B, C

Explanation

The correct answers are A, B, and C because these configurations prevent the assignment of an IP address to the interface. Specifically, one-arm sniffer mode and virtual wire pairs do not allow IP configuration, and a transparent mode operation also restricts IP address assignments. Options D and E do not inherently prevent IP address configuration.
