NSE 4 – FortiGate 6.2 — Question 68

An administrator observes that the port1 inteface cannot be configured with an IP address.
What are three possible reasons for this? (Choose three.)

Answer options

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

Correct answer: A, B, D

Explanation

The correct answers are A, B, and D. In transparent mode (A), interfaces do not require IP addresses. If the interface is part of a virtual wire pair (B), it cannot have an IP address assigned. A one-arm sniffer configuration (D) also does not allow for IP address assignment. Options C and E do not prevent IP configuration; a member of a zone can still have an IP, and enabling a captive portal does not restrict IP address configuration.
