Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 27

Which configuration do you apply to an interface so that it uses port security to learn and commit the first MAC address?

Answer options

• A. Configure the switchport switch-port security violation restrict 1 command.
• B. Enable the sticky MAC addresses feature.
• C. Enable the static secure MAC addresses feature.
• D. Configure the switch for port-security aging type inactivity command.
• E. Configure the switchport port-security maximum 1 command.
• F. Disable the sticky MAC addresses feature.

Correct answer: E

Explanation

The correct answer is E because configuring the switchport port-security maximum 1 command allows the interface to learn and commit the first MAC address by limiting the number of MAC addresses to one. Options A, B, C, D, and F do not specifically address the requirement of learning and committing a single MAC address, thus they are not correct in this context.
