Which TWO of the following are common types of network cables used in wired Ethernet networks?
⚠ Common exam trap
Test-takers frequently confuse coaxial cable's historical use in Ethernet (e.g., 10BASE2) with modern wired Ethernet standards, forgetting that today's common Ethernet deployments use twisted-pair (Cat5e/Cat6) or fiber, not coax.

Correct answer & explanation
✓
Cat5e
Cat5e (Category 5 enhanced) is a twisted-pair copper cable standard that supports Gigabit Ethernet (1000BASE-T) up to 100 meters. It is one of the most common cable types for wired Ethernet networks because it provides sufficient bandwidth (up to 1000 Mbps) and is backward compatible with older 10/100 Mbps standards.
