QID: AR316 has wrong answer - adilnasser3 - 04-20-2026 The correct answer for this question is IPv6 Snooping.  See validated result from chatgpt below: what is the correct answer to this question? The correct answer is: IPv6 Snooping Here’s why: IPv6 Snooping (ND Snooping) monitors and controls Neighbor Discovery (ND) traffic such as Neighbor Solicitations and Advertisements. It builds a binding table (IP ↔ MAC ↔ interface), which is essential for proper neighbor discovery operation and performance. It essentially ensures that the discovery process works correctly and securely by validating and tracking that traffic. Why the others are wrong: RA Throttling → only limits Router Advertisement rates, not overall neighbor discovery behavior Source/Destination Guard → filters traffic based on bindings, but doesn’t control discovery traffic itself ND Multicast Suppression → reduces multicast flooding for efficiency, but doesn’t manage correctness of discovery So your selected answer (ND Multicast Suppression) is close conceptually (performance-related), but the question is really about controlling and validating discovery traffic, which points directly to IPv6 Snooping. Please correct the answer for this question. Thanks, Adil
