Essential Interview Questions and Answers

Network troubleshooting is a crucial skill for IT professionals. Here are some top interview questions and answers to help you prepare for a job in network support.

What is a Network Repeater?

A network repeater is a device that receives a digital signal on an electromagnetic or optical transmission medium, amplifies it, and then retransmits it. This allows for the extension of the transmission range of the signal by increasing its power.

Additionally, when setting up networks that require PoE, or Power over Ethernet, it’s essential to understand the components and technologies involved. For instance, understanding how a Meraki PoE switch enables you to power devices like IP cameras and phones directly over the network cable can be critical in designing efficient network infrastructure.

Diagnosing Network Issues

One of the key challenges in network troubleshooting is identifying the root cause of network slowdowns or outages. Tools like network analyzers and protocol analyzers can be essential in diagnosing these issues.
