CCNA: Cisco Certified Network Associate — Question 22

Two switches are connected and using Cisco Dynamic Trunking Protocol. SW1 is set to Dynamic Auto and SW2 is set to Dynamic Desirable. What is the result of this configuration?

Answer options

• A. The link becomes an access port.
• B. The link is in an error disabled state.
• C. The link is in a down state.
• D. The link becomes a trunk port.

Correct answer: D

Explanation

In this configuration, SW1 in Dynamic Auto mode will respond to SW2, which is in Dynamic Desirable mode, and negotiate a trunk link. Therefore, the correct answer is D, as the link will successfully become a trunk port. Options A, B, and C are incorrect because they describe states that do not occur under these settings.
