Answer options

• B. used in service provider deployments to protect DDoS attacks
• C. requires that validate prefix be enabled
• D. requires IPv6 snooping on Layer 2 access or trunk ports
• E. recovers missing binding table entries

Correct answer: A, D

Explanation

Option A is correct because IPv6 Source Guard relies on the configuration of static bindings to function properly.
