When attaching a new host to the fabric, which of the following is created on the switch to easily manage the host?

An Inter-Switch Link (ISL) connects two Fibre Channel switches to expand the fabric, not a host to a switch for management.

An alias, specifically a device alias, is a user-defined name assigned to a World Wide Port Name (WWPN) or a set of WWPNs on a Fibre Channel switch. This allows administrators to use an easily recognizable name instead of a long hexadecimal WWPN when configuring zoning and other fabric services, making management intuitive.

A DNS record maps hostnames to IP addresses, which is relevant for IP networks and not directly for Fibre Channel fabric management on the switch.

A trunk in Fibre Channel refers to bundling multiple ISLs to increase bandwidth and redundancy between switches, not to manage a single host connection.
