200-301 Question #91: Real Exam Question with Answer & Explanation

The correct answer is C: CDP operates normally,but it cannot provide IP address information for that neighbor.

If the neighbor does not has an IP address then CDP still operates without any problem. But the IP address of that neighbor is not provided.
