Which of the following commands can be used to review the status of VLANs on a switch?

• A. show version
• B. show vlan brief
• C. show ip interface
• D. show running-config

Answer: (B)

The command "show vlan brief" is specifically designed to provide a concise overview of VLANs on a switch. When executed, it displays details such as the VLAN ID, name, and status of all VLANs configured on the device. This information is vital for network administrators to quickly assess how VLANs are set up and to diagnose any issues related to VLAN configurations. The other commands serve different purposes. "show version" provides information about the switch's hardware and software version but does not include VLAN details. "show ip interface" displays the status and configuration of interfaces, including IP addressing, but does not focus on VLAN information. Lastly, "show running-config" presents the entire current configuration of the switch, which includes VLANs but in a far less concise way compared to "show vlan brief." This makes "show vlan brief" the most effective choice for reviewing VLAN status.
