Drag and drop the steps of Cisco DHCP snooping binding table population into the correct order, from first to last.

Correct answer & explanation
✓
Switch receives DHCPACK from trusted server port
DHCP snooping first validates DHCP server messages on trusted ports, then creates a binding entry from the DHCPACK, stores the entry with MAC/IP/port/VLAN, updates the table on lease renewal, and finally removes the entry on lease expiry or DHCPRELEASE.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Drag and drop the steps of Cisco DHCP snooping binding table population into the correct order, from first to last.
medium- ✓ A.Enable DHCP snooping globally on the switch
- ✓ B.Enable DHCP snooping on specific VLANs
- ✓ C.Configure trusted ports for DHCP server connections
- ✓ D.Switch intercepts DHCPACK from server
- ✓ E.Populate binding table with MAC, IP, VLAN, port, lease
Why A: DHCP snooping builds the binding table by first enabling snooping globally, then on specific VLANs, and designating trusted ports. The switch intercepts DHCP messages, extracts client info from ACK packets, and populates the binding table with the lease information.
