Why each option
Fibre Channel defines three standard topologies: Point-to-Point, Arbitrated Loop, and Switched Fabric.
Spine and leaf is an IP/Ethernet data center architecture topology, not a defined Fibre Channel topology.
Point-to-Point (port-to-port) is one of the three official FC topologies, directly connecting two N_Ports for dedicated bandwidth between a single pair of devices.
Port-to-multipoint is not a recognized Fibre Channel topology; multi-device FC connectivity is achieved through Switched Fabric, not a multipoint topology.
Star topology is a generic networking term and is not one of the three formally defined Fibre Channel topologies in the FC standards.
Arbitrated Loop (FC-AL) is another official FC topology where up to 127 devices share a loop, with only one device communicating at a time after winning loop arbitration.
