Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 130

In which two circumstances does a port security violation occur? (Choose two.)

Answer options

• A. when sticky MAC address learning is enabled and the port has a link-down condition
• B. when a port with a secure MAC address attempts to use a different port in the same VLAN
• C. when the same MAC addresses enters a port more than once
• D. when the CAM table overflows with dynamically learned MAC addresses
• E. when the port has received more MAC addresses than allowed

Correct answer: B, E

Explanation

Option B is correct because a violation occurs if a port with a secure MAC address attempts to utilize a different port in the same VLAN. Option E is also correct as it indicates the port has received an excessive number of MAC addresses, exceeding its configured limit. The other options do not lead to port security violations under the defined criteria.
