Which Ethernet connector is commonly used for standard LANs and has 8 positions?

• A. Ethernet (RJ45)
• B. Ethernet (RJ11)
• C. Ethernet (Shielded Twisted Pair)
• D. Ethernet over Power

Answer: (A)

RJ45 is the connector most commonly used for standard LANs and it has eight positions, eight pins that mate with a matching jack on devices and wall outlets. This eight‑pin design is what supports the Ethernet signals carried over twisted-pair cables like Cat5e and Cat6. The other options don’t fit: RJ11 is smaller and designed for telephone lines with typically six positions; Shielded Twisted Pair describes a cable construction, not a connector type; Ethernet over Power uses adapters to send data over electrical outlets, not a specific connector.
