SG0-001 · Question #171

Which of the following ports is MOST commonly used with FC-AL?

The correct answer is C. NL-port. The NL-port is the specific Fibre Channel port type used by end devices, such as HBAs, to connect to a Fibre Channel Arbitrated Loop (FC-AL).

Why each option

The NL-port is the specific Fibre Channel port type used by end devices, such as HBAs, to connect to a Fibre Channel Arbitrated Loop (FC-AL).

AF-port

An F-port (Fabric port) is a switch port that connects to an N-port on a node in a switched Fibre Channel fabric topology, not directly to an FC-AL end device.

BN-port

An N-port (Node port) is an end device port that connects to an F-port on a Fibre Channel switch, not typically used for direct connection to an FC-AL.

CNL-portCorrect

An NL-port (Node Loop port) is designed for devices that connect to a Fibre Channel Arbitrated Loop (FC-AL), allowing the device to participate in the loop topology. This is the correct port type for end devices in an FC-AL environment.

DTE-port

A TE-port (Trunking Expansion port) is not a standard Fibre Channel port type primarily associated with FC-AL; it's typically related to inter-switch link (ISL) trunking.
