what is the best tool to use if you suspect your nic has failed?

• loopback plug
• cable tester
• network multimeter
• toner probe

Explanation:

Identify the diagnostic target

The question asks for the best tool to test a suspected failed Network Interface Card (NIC).

Analyze the available options

• Loopback plug: Used to test the physical port of a NIC by routing the outgoing signal directly back into the receiving port to verify if the card can send and receive data.
• Cable tester: Used to test physical network cables for continuity, shorts, or wiring faults.
• Network multimeter: Used to measure electrical properties of network cables and ports, but is not the primary tool for testing NIC functionality.
• Toner probe: Used to locate and trace specific cables within a bundle or wall.

Determine the correct tool

A loopback plug is specifically designed to test the transmit and receive functions of a NIC to determine if the hardware itself has failed.

Answer:

• Loopback plug (Correct answer)
• Cable tester
• Network multimeter
• Toner probe
