Final answer:
To configure a new Cisco switch for remote management, an administrator needs to configure an IP address, vty lines for remote CLI sessions, and a default gateway to allow communication with external networks.
Step-by-step explanation:
To configure a new Cisco switch for remote management access, a network administrator must set up several key items. Three essential configurations required for remote access are:
- IP address: This is necessary for the switch to participate in a network and to be accessible over the network. It is the identifier for the switch on the network.
- vty lines: Virtual teletype lines are used for remote access protocols like SSH and Telnet. Configuring vty lines enables the administration of the switch remotely through command-line interface sessions.
- default gateway: The default gateway allows the switch to send traffic to destinations outside of its local network, which is necessary when managing the switch from a non-local network.
- Settings such as the VTP domain, default VLAN, and loopback address are not mandatory for remote access, but they could play a role in other network configurations and management tasks.
