Which two (2) are advantages of ISL over-subscription? (Choose two.)

ISL over-subscription optimizes bandwidth usage by allowing the aggregate bandwidth of connected devices to exceed the ISL's physical bandwidth, assuming that not all devices will simultaneously demand full bandwidth. This leads to more efficient utilization of the costly ISL resources.

ISL over-subscription is a configuration strategy for existing ports and does not inherently lower the initial cost-per-port of the switch hardware.

Over-subscription does not increase the performance of a single ISL; it allows more aggregate traffic to pass through, but can lead to congestion if traffic exceeds the ISL's actual capacity.

ISL over-subscription is unrelated to zoning configuration; zoning complexity depends on the number of initiators and targets, not ISL bandwidth management.

By over-subscribing ISLs, a Fibre Channel switch can dedicate more of its physical ports to connecting end devices (hosts, storage arrays) as F_Ports, rather than reserving them for potential full-speed ISLs, thus making more F_Ports available.
