Chapter 3: Hardware

3.1 Explain basic cable types and their connectors, features, and purposes

  1. The correct answer is A. Copper cables are subject to signal attenuation, which refers to the loss of signal strength over distance. Copper cables can be susceptible to electromagnetic interference. This will reduce speed but is not the main limitation. Bandwidth limitation primarily affects the overall capacity of the network but does not directly impact the speed of data transmission. Insulation-related issues are more likely to cause signal quality problems rather than limiting the speed of data transmission.
  2. The correct answer is A. An Optical Time Domain Reflectometer (OTDR) is a tool used for troubleshooting and testing fiber optic cables. It sends light pulses into the cable and measures the reflections to identify any issues, such as breaks or signal loss. Wire cutters are used for cutting wires and not troubleshooting fiber optic cables. An Ethernet cable tester is used...
