NCCER 33108 Limited-Energy Cabling Practice Test

The main idea is recognizing which Ethernet standard is defined by using thick coax cable at a 10 Mbps rate. Thicknet, or 10BASE-5, is the standard that uses thick coax cable for a 10 Mbps Ethernet bus. It uses a relatively sturdy coax (RG-8/RG-11), a bus topology with BNC connectors and vampire taps, and requires terminators at both ends to prevent signal reflections. This distinguishes it from Thinnet (10BASE-2), which uses thinner coax, and from terms like Ethernet or coaxial that are too broad and don’t specify the cable type or speed.
