Answer: A

Explanation:

DHCP snooping is a security feature that acts like a firewall between untrusted hosts and trusted DHCP servers. The DHCP snooping feature performs the following activities:

Validates DHCP messages received from untrusted sources and filters out invalid messages.

Rate-limits DHCP traffic from trusted and untrusted sources. ꞏ Builds and maintains the DHCP snooping binding database, which contains information about untrusted hosts with leased IP addresses.

Utilizes the DHCP snooping binding database to validate subsequent requests from untrusted hosts. Reference: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst6500/ios/12- 2SX/configuration/ guide/book/snoodhcp.pdf
