To view VLAN pruning status in a network with Cisco devices, the command that provides this information is indeed related to the VLAN Trunking Protocol (VTP). Using the command that shows the VTP status allows you to see details such as whether VTP pruning is enabled or disabled. When VTP pruning is enabled, it helps to optimize bandwidth by not sending unnecessary VLAN traffic across trunk links. The command provides critical information about the configuration of the VTP domain, including the pruning capability, which affects how VLAN traffic is managed. Understanding VTP and VLAN pruning is key for maintaining efficient network performance, especially in larger environments where multiple VLANs may be in use. Other commands listed do not directly provide VLAN pruning status. For instance, the command to show VLANs focuses on the VLANs defined on the switch rather than pruning information, while the command for showing IP interface brief mainly lists interface status without addressing VLANs. Lastly, the command for an interface would give details about that specific interface but would not indicate whether VLAN pruning is active. Therefore, checking the VTP status is the most relevant and accurate method for assessing VLAN pruning in a Cisco network environment.
