Exam 220-1101 topic 1 question 354 discussion

A A network tap is a device that can be used to monitor and analyze the traffic and data that pass through a network. A network tap can be inserted between two network devices, such as a switch and a router, and capture the packets that flow in both directions. A network tap can then send a copy of the packets to another device, such as a laptop or a server, for inspection and troubleshooting. A network tap can help diagnose and resolve network issues, such as performance, security, or configuration problems.

B IT IS

The correct answer is B. Cable tester. A cable tester is a tool that allows a technician to quickly and non-intrusively test the status of a network cable and the device it's connected to, without disrupting the network or other devices. It's a simple, handheld tool that can detect issues like cable faults, connectivity problems, or device status. Here's why the other options are not the best choice: A. A network tap is a passive device that copies network traffic for monitoring purposes, but it's not designed for troubleshooting local network devices. C. A multimeter is a tool used to measure electrical properties like voltage, current, and resistance, but it's not suitable for troubleshooting network devices. D. A tone generator is a tool used to trace cables and identify wiring issues, but it's not designed to check the status of a local network device. By using a cable tester, the technician can quickly and non-intrusively check the status of the local network device, minimizing disruption to the network and other devices.

A network tap is a passive device that doesn't disrupt network traffic. It simply copies the traffic passing through it to another device, like a monitoring tool or an intrusion detection system. This allows the technician to check the status of the local network device without disrupting normal network operations.

A. Network tap To check the status of a local network device in the least disruptive manner, a technician should use a network tap. A network tap allows the technician to monitor network traffic without interrupting or disrupting the normal operation of the network.

B. Cable tester A cable tester is a tool used to check the connectivity and continuity of network cables without disrupting the network. It can verify that the cables are properly terminated and help identify issues such as breaks or miswiring. Using a cable tester allows the technician to troubleshoot the network issue without causing disruption to the network itself.

A network tap is the least disruptive tool for checking the status of a local network device, because it does not interfere with the normal operation of the network. A network tap does not alter or block the packets that it captures, and it does not introduce any latency or noise to the network.

The correct is B
