RJ45 Connector: Pinout, Types, Uses and Ethernet Wiring ⋆ IpCisco

Please sign up for the course before taking this quiz.

1. Which RJ45 connector type is generally more appropriate for an environment with significant electromagnetic interference (EMI)?
1
- RJ11
- Shielded RJ45
- Standard telephone connector
- Unshielded RJ45
2. Why are crossover Ethernet cables less commonly required with modern network devices?
1
- Modern Ethernet uses only four wires
- Fiber optic cables replaced them completely
- T568A is no longer supported
- Auto-MDI/MDIX can automatically handle transmit and receive pair orientation
3. What should you use after crimping an RJ45 connector to check the cable for common wiring problems?
1
- SFP transceiver
- Wireless controller
- Multilayer switch
- Cable tester
4. How many positions and contacts does the connector commonly called RJ45 use in Ethernet cabling?
1
- 10P8C
- 6P4C
- 4P4C
- 8P8C
5. In the T568B wiring standard, which color is used on Pin 1?
1
- White/Orange
- Green
- White/Green
- Blue
6. Which statement about RJ45 and SFP is correct?
1
- SFP ports always use RJ45 connectors
- RJ45 is a modular transceiver and SFP is an Ethernet cable
- RJ45 is commonly used with twisted-pair copper Ethernet, while SFP can support fiber or copper depending on the transceiver
- Both can only be used with fiber optic cables
7. Which wiring standards are commonly used for terminating RJ45 Ethernet connectors?
1
- T568A and T568B
- T568C and T568D
- Cat6 and Cat6A
- IEEE 802.1Q and 802.1X
8. What is the main difference between T568A and T568B?
1
- T568A uses only four conductors
- The blue and brown pairs are reversed
- The orange and green pairs swap positions
- T568B supports higher Ethernet speeds
