Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 142

Which three functions does Dynamic ARP Inspection perform with invalid IP-to MAC address bindings?

Answer options

• A. deletes
• B. logs
• C. accepts
• D. intercepts
• E. discards
• F. bypasses

Correct answer: B, D, E

Explanation

The correct options are B, D, and E because Dynamic ARP Inspection logs the invalid bindings, intercepts the ARP requests, and discards those that do not match valid entries. Options A (deletes) and C (accepts) do not accurately describe the functions of Dynamic ARP Inspection, as it does not delete valid bindings or accept invalid ones.
