What is the flexible connection used to connect the equipment to the hardline?

• A. Tap
• B. Cable Tie
• C. Stub
• D. Jumper

Answer: (D)

This tests understanding of the flexible link used to bridge a rigid hardline to equipment. The correct term is a jumper. A jumper is a short, flexible connector—often a coaxial or other RF cable with connectors on both ends—that links the equipment to the hardline while accommodating movement, mounting, and easy disconnection for maintenance. It preserves the signal path with proper impedance, minimizing reflections when chosen and installed correctly.

Why the other options don’t fit: a tap is a device that extracts a portion of signal from the main line, not a flexible bridge to connect devices; a stub is a short length of line used for termination or tuning, not for connecting equipment to the hardline; a cable tie is merely a strap for securing cables, not an electrical connector.

So the flexible connection used to connect the equipment to the hardline is a jumper.
