Which of the following test devices are used to verify the pin-to-pin connectivity between two ends of a cable?
  1. TDR
  2. Wiremap
  3. Multimeter
  4. Tone generator
Explanation
Answer - B - Wiremap is used to verify the pin-to-pin connectivity between two ends of a cable.

Key Takeaway: Wiremap is a test to ensure that the two ends have been terminated pin for pin. This means pin 1 at the patch panel goes to pin 1 at the outlet, and pin 2 goes to pin 2. Wiremap also checks for continuity, shorts, crossed pairs, reversed pairs, and split pairs.
