Packet filtering based on IP/port criteria
Limits MAC addresses per switchport
Prevents rogue DHCP server attacks
Validates ARP packets to prevent spoofing
Filters traffic based on IP/MAC binding
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Port Security: Limits the number of MAC addresses allowed on a port.
Port Security limits MAC addresses per port; DHCP Snooping filters DHCP messages and builds a binding database; Dynamic ARP Inspection validates ARP packets; IP Source Guard filters traffic based on binding table. Common confusions include mixing DHCP Snooping with DAI and Port Security with DHCP Snooping.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Port Security: Limits the number of MAC addresses allowed on a port.
Why this is correct
Port Security restricts the number of MAC addresses learned per port, preventing MAC flooding attacks.
Port Security: Filters DHCP messages to prevent rogue servers.
Why it's wrong here
Incorrect — this describes DHCP Snooping, not Port Security.
DHCP Snooping: Filters untrusted DHCP messages and builds a binding database.
Why this is correct
DHCP Snooping drops DHCP messages from untrusted sources and maintains a MAC-IP binding table.
DHCP Snooping: Validates ARP packets to prevent spoofing.
Why it's wrong here
Incorrect — this describes Dynamic ARP Inspection, not DHCP Snooping.
Dynamic ARP Inspection: Validates ARP packets to prevent spoofing.
Why this is correct
DAI inspects ARP packets against the DHCP snooping binding database to prevent man-in-the-middle attacks.
IP Source Guard: Filters IP traffic based on source IP and MAC from DHCP snooping.
Why this is correct
IP Source Guard uses the DHCP snooping database to filter traffic, allowing only valid source IP-MAC pairs.
