Exam N10-008 topic 1 question 876 discussion

DHCP snooping is used to prevent unauthorized DHCP servers from assigning IP addresses and other configuration settings, such as DNS servers, to network hosts. By implementing DHCP snooping, you can protect against attacks where a rogue DHCP server provides malicious configuration information, such as a fake DNS server. The other options—port security, 802.1X authentication, and MAC filtering—address different types of security issues and do not specifically prevent unauthorized DHCP servers from affecting network configurations.
