A. Boost signal strength
B. Organize and manage cable connections
, C. Encrypt network traffic
D. Provide power over Ethernet
Correct Answer: B
A patch panel helps organize and manage multiple network cable
connections.
9. Which tool is used to remove the outer jacket of a cable?
A. Punch down tool
B. Cable stripper
C. Crimp tool
D. Wire tester
Correct Answer: B
A cable stripper safely removes the outer insulation without damaging
internal wires.
10. What does UTP stand for?
A. Unified Transmission Protocol
B. Unshielded Twisted Pair
C. Universal Transfer Port
D. Ultra Thin Pair
