Which interface allows remote management of a Layer 2 switch?

• A. AUX interface
• B. The console port interface
• C. The switch virtual interface
• D. The first Ethernet port interface

Answer: (C)

Remote management of a Layer 2 switch is possible when the switch has an IP address reachable over the network, which is provided by a Switch Virtual Interface tied to a management VLAN. This virtual interface gives the switch a management IP that you can reach with SSH, Telnet, or SNMP from other devices. The console port is for local, direct access with a console cable, and the AUX port is typically used for out-of-band dial-in; the regular Ethernet ports are for data traffic, not for management. So the interface that enables remote management is the Switch Virtual Interface.
