An airport authority must stop rogue IPv6 Router Advertisements from appearing on access ports serving passenger and staff devices. Which feature is designed for that threat?
Select an answer to reveal the explanation.
Short Explanation
RA Guard is the ‘authorized routers only’ sign for IPv6. Access ports can’t spew fake Router Advertisements that yank hosts toward a rogue gateway.
Full Explanation
IPv6 Router Advertisement Guard filters RAs so only trusted ports (or properly role-classified ports) may forward them, protecting hosts from malicious prefix and gateway information. IPv4 DHCP snooping, multicast RP design, and storm control on hellos do not replace RA Guard for this first-hop IPv6 threat.
