Which command allows a Cisco switch to operate in the static mode for VLAN configuration?

The command that allows a Cisco switch to operate in static mode for VLAN configuration is "switchport mode access." This command is used on switch interfaces to configure them as access ports, which means these ports will belong to a single VLAN and will not trunk multiple VLANs. When an interface is set to access mode, it will forward traffic for only the VLAN specified with the 'switchport access vlan' command. This is essential for the proper segmentation of network traffic based on VLAN membership.

Static VLAN configuration is fundamental for defining which devices are part of which VLAN, maintaining control over broadcast domains, and ensuring that network policies are consistently applied. In this way, using access mode enables the switch to function within a defined VLAN structure, operating as intended for typical end-user devices in a switched network.

Other options listed do not represent valid commands for configuring VLANs on a Cisco switch. Such commands may not exist or are misnamed, leading to confusion on how to properly set VLAN modes on switch interfaces.
