CCNA Routing and Switching (legacy) — Question 63

A network administrator needs to configure port security on a switch. Which two statements are true? (Choose two.)

Answer options

• A. The network administrator can apply port security to dynamic access ports.
• B. The network administrator can apply port security to EtherChannels.
• C. The sticky learning feature allows the addition of dynamically learned addresses to the running configuration.
• D. When dynamic MAC address learning is enabled on an interface, the switch can learn new addresses, up to the maximum defined.
• E. The network administrator can configure static secure or sticky secure MAC addresses in the voice VLAN.

Correct answer: C, D

Explanation

Option C is correct because the sticky learning feature allows dynamically learned MAC addresses to be saved in the running configuration, enhancing security. Option D is also correct as it confirms that the switch can learn new MAC addresses dynamically, respecting the configured limits. Options A, B, and E are incorrect; they do not accurately reflect the capabilities of port security in the context given.
