Straight-Through Cable — CompTIA Network+ (N10-009) Practice Questions

A straight-through cable uses the same wiring standard (T568A or T568B) on both ends and is used to connect unlike devices such as a host to a switch or a switch to a router. The N10-009 exam tests when to use a straight-through cable versus a crossover cable, which connects like devices. Modern switches support Auto-MDIX, which automatically negotiates the correct pair mapping regardless of cable type, but the exam still expects candidates to know the traditional rules. Understanding cable types is a common element of troubleshooting connectivity questions.
