DHCP snooping is a security feature that is used to prevent rogue DHCP servers from distributing incorrect IP addresses to network clients. The feature is used in conjunction with Dynamic Host Configuration Protocol (DHCP) to ensure that only authorized DHCP servers are used to assign IP addresses to clients on a network. The two benefits of DHCP snooping are as follows:

  1. It prevents the deployment of rogue DHCP servers: Rogue DHCP servers can be deployed on a network by an attacker or by an unsuspecting user who wants to set up their own DHCP server. This can lead to clients being assigned incorrect IP addresses, which can cause network connectivity problems. DHCP snooping helps prevent rogue DHCP servers by only allowing DHCP traffic from authorized servers on trusted ports. Untrusted ports are blocked, preventing rogue DHCP servers from distributing IP addresses.

  2. It simplifies the process of adding DHCP servers to the network: When adding a new DHCP server to a network, DHCP snooping can help simplify the process. DHCP snooping can automatically configure the switch to trust the new DHCP server and allow DHCP traffic on the appropriate ports. This can help save time and prevent configuration errors.

The other options listed in the question are incorrect. DHCP snooping does not prevent DHCP reservations or static reservations, nor does it track the location of hosts in the network.
