An administrator would like to combine several ISLs into a single virtual connection. Which of the following technologies should be implemented to accomplish this?

LUN Masking is a security feature that controls which hosts can access specific Logical Unit Numbers (LUNs) on a storage array, unrelated to combining ISLs.

In Fibre Channel networks, Trunking (often called ISL Trunking or Port Channeling) allows multiple physical ISLs between two Fibre Channel switches to be bundled together. This creates a single logical link with increased aggregate bandwidth and provides fault tolerance, as traffic can be load-balanced and redirected if one physical link fails.

Flow Control is a mechanism to regulate data transmission between devices to prevent receiver overload, not for bundling links.

VLAN Trunking is an Ethernet technology used to carry traffic for multiple Virtual LANs (VLANs) over a single physical link, not for Fibre Channel ISLs.
