A network administrator configures DHCP snooping on VLAN 2. How does the switch handle DHCP traffic that arrives in this VLAN on an untrusted interface?

When DHCP snooping is configured on a VLAN, the switch differentiates between trusted and untrusted interfaces. Trusted interfaces are typically those connected to known DHCP servers, and untrusted interfaces are usually those connected to clients. The purpose of DHCP snooping is to prevent rogue DHCP servers from providing incorrect IP addresses. Therefore, the switch accepts DHCP client packets (such as Discover and Request messages) on untrusted interfaces, but it drops packets from DHCP servers (such as Offer and Acknowledgment messages) that arrive on untrusted interfaces to protect the network from rogue servers.
I think the answer is D.
Correct: D
only DHCP servers should send Offer and Acknowledgement packets, so if the switch detects these types of packets on an untrusted port, it immediately discards them. On the untrusted ports, the switch only accepts DHCP client packets Discover Request Decline Inform Release
Answer is D
Correct, D.
