FC-AL shares the loop and only one device can perform I/O operations at a time. Because each device in a loop must wait for its turn to process an I/O request, overall performance in FC-AL environment is low.

Answer D: requires one connectivity device as they are implemented using Star or ring topology as a loop. it can support only 126 nodes, due to the topology devices cannot be removed dynamically, no address reservation for FC-SW port.

Above comments are wrong apologies.
Answer is A: One address is reserved for optionally connecting the loop to an FC switch port out of 127 valid addresses.

Answer is A.
ISMv2 pg138/Module 5 pg16
”
FC-AL uses 8-bit addressing and allows the assignment of 127 valid addresses to the ports. Hence, it can support up to 127 devices on a loop. One address is reserved for optionally connecting the loop to an FC switch port. Therefore, up to 126 nodes can be connected to the loop.”
