Answer: C - To complete the installation of an IDF or MDF, you will most likely need the Punch-Down tool.

Key Takeaway: A punch down tool punches individual wires into the patch panel of an RJ45 jack for termination-this usually looks like a large cabinet with hundreds of small wires running throughout it. Since the Main Distribution Facility (MDF) and Intermediate Distribution Facility (IDF) are where these drops are terminated, using a punch down tool will be necessary. A Stripper and Crimper are used to create the actual cable, and a cable tester will be used to test its functionality.
