CCNA: Cisco Certified Network Associate — Question 132

In a CDP environment, what happens when the CDP interface on an adjacent device is configured without an IP address?

Answer options

• A. CDP becomes inoperable on that neighbor
• B. CDP uses the IP address of another interface for that neighbor
• C. CDP operates normally, but it cannot provide IP address information for that neighbor
• D. CDP operates normally, but it cannot provide any information for that neighbor

Correct answer: C

Explanation

The correct answer is C because CDP can still operate even if the neighboring device's interface lacks an IP address, but it will not be able to convey IP address details. Options A and D are incorrect because CDP does not stop functioning entirely, and option B is incorrect as CDP cannot use another interface's IP address in this scenario.
