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

An interface configured for one-arm sniffer mode requires an IP address for management and for the sniffer to function and collect traffic.

An interface configured as part of a virtual wire pair operates at Layer 2 and does not carry an IP address, as the FortiGate functions transparently like a bridge.

When the FortiGate is operating in transparent mode, most interfaces function as Layer 2 bridges and therefore do not have their own IP addresses configured.

If an interface is a member of a software switch or hardware switch (which logically group interfaces for Layer 2 functionality, akin to a zone), the IP address is configured on the switch interface itself, not on the individual member interfaces.

Enabling a captive portal on an interface requires that interface to have an IP address to redirect user traffic and present the portal page.
