What interface allows for the remote management of a Layer 2 switch?

The choice of "Switch virtual interface" (SVI) is correct because it serves as a virtual interface associated with a VLAN on a Layer 2 switch, allowing for remote management and communication. In a typical switch configuration, an SVI is created for the purpose of management. When a VLAN is defined and an IP address is assigned to its SVI, it allows network administrators to manage the switch remotely using protocols like SSH or Telnet.

An SVI acts as a gateway for devices within that VLAN and provides a means for devices in different VLANs to communicate, which is essential for managing Layer 2 switches across a network. This approach utilizes Layer 3 capabilities (like IP addressing) on a device primarily operating at Layer 2.

The other options lack the specific functionality required for remote management. A VLAN interface could be a reference to the same concept but lacks the specific naming convention that emphasizes its role in routing or management. An Ethernet interface generally refers to physical interfaces on the switch rather than a virtual layer, while a port channel interface is related to link aggregation and not specifically designed for remote management. Hence, the SVI is the most appropriate and recognized method for remote management of a Layer 2 switch.
