Explanation:

Analyze the question requirements

The question asks to identify which of the listed tools can be used to determine if a network cable is good, with the instruction to "Choose all that apply."

Evaluate "Cable tester"

Using the Cable Testing Tools knowledge point
A cable tester is specifically designed to test the physical connections and continuity of a network cable to verify if it is good.

Evaluate "Crimper"

A crimper is a tool used to attach connectors (like RJ-45) to the ends of a cable. It does not test or verify the electrical integrity or quality of the cable.

Evaluate "Loopback plug"

Using the Loopback Plug knowledge point
A loopback plug is used to test the transmit and receive ports of a network interface card or port, not to test a standalone network cable's integrity.

Evaluate "Patch Panel"

A patch panel is a passive connection hub used to organize and route cabling runs. It has no diagnostic or testing capabilities to determine if a cable is good.

Answer:

• Cable tester (Correct answer)
• Crimper
• Loopback plug
• Patch Panel
