On a multilayer switch, a switch needs to be configured to perform DHCP Snooping on some Layer 2 ports in VLAN 3. Which command may or may not be needed depending on whether the switch also acts as a DHCP relay agent?
- no ip dhcp snooping information option
- ip dhcp snooping limit rate 5
- errdisable recovery cause dhcp-rate-limit
- ip dhcp snooping vlan 3
Explanation: All the answers list commands with correct syntax that are useful for DHCP Snooping; however, the correct answer, no ip dhcp snooping information, disables DHCP Snooping’s feature of adding DHCP Option 82 fields to DHCP messages. This setting is useful if the switch does not act as a DHCP relay agent. The opposite setting (without the no to begin the command) works when the multilayer switch acts as a DHCP relay agent.
