To enable DHCP Snooping for a specific VLAN, it is essential to configure the command that specifically designates which VLANs will participate in DHCP Snooping. This is done with the command that includes the VLAN identifier, indicating the network segment that will have its DHCP messages monitored and controlled.

By using this specific command, DHCP Snooping is effectively activated for the designated VLAN, allowing the switch to filter incoming DHCP messages and protect the network from potential DHCP-related attacks, such as rogue DHCP servers. This selective approach is crucial because enabling DHCP Snooping globally without specifying the VLAN would not limit the protection to just the intended segment, potentially leaving other VLANs vulnerable.

In contrast, the other choices either lack the requirement of VLAN specificity or do not refer directly to the configuration needed to apply DHCP Snooping specifically to a VLAN. The command focusing on the VLAN identifier directly impacts how DHCP Snooping operates, ensuring that it only applies to the designated VLANs, thus forming a necessary component of the configuration process for maintaining network security and integrity.
