Correct answer & explanation
✓
Enable DHCP snooping globally
DHCP snooping begins by enabling the feature globally with 'ip dhcp snooping'. Then, the feature is enabled on specific VLANs. Trusted interfaces (typically uplinks to DHCP servers) are configured with 'ip dhcp snooping trust'. The switch then intercepts DHCP messages, building the DHCP snooping binding database from valid server responses. Finally, any DHCP server messages received on untrusted interfaces are dropped to prevent rogue server attacks.
