About This Quiz
CompTIA Network Plus Quizzes & Trivia

This part of the CompTIA Network+ Certification exam tests knowledge on various network connectors. It covers RJ-45 for twisted pair cables, BNC for co-axial cables, and ST and SC for fiber-optic cables, essential for anyone working in network setup and maintenance.

2.

What first name or nickname would you like us to use?

You may optionally provide this to label your report, leaderboard, or certificate.

6. You have two workstations each with a 100Base-T network card.  You want to connect the two workstation  directly without the use of a hub or switch.  Which cable would you use?

Explanation

Both workstation network interface cards (NICs) will be physically and electronically the same medium dependent interface (MDI), therefore, you need a crossover cable to connect the two together. 100Base-T has a transmission speed of up to 100 Mbps. The minimum twisted-pair, copper cable that can support these speeds is CAT5 cable.

Submit

7. The network you work on has a 100Base-T switch.  You need to add a new host to the network.  Which cable would you require?

Explanation

100Base-T uses twisted pair cable as indicated by the T in 100Base-T. 100Base-T has a transmission speed of up to 100 Mbps. The minimum twisted-pair, copper cable that can support these speeds is Category 5 cable.

Submit

8. Which of the following statements BEST describes CAT5 cable?

Explanation

CAT5 cable has four pairs of twisted copper wire with a throughput of 100 Mbps

Submit

9. Which of the following fiber-optic solutions uses the longest wavelength beams?

Explanation

10GBase-ER uses extra long wavelength beams of 1550 nm.

Submit

10. Which of the following would require a BNC connector?

Explanation

10Base-2, which is Thinnet, uses RG-58 co-axial cable with BNC connectors.

Submit

11. Which type of connector would be used for Thinnet?

Explanation

BNC connectors are used on RG-58 co-axial cable as used in Thinnet.

Submit

12. You work as a technician on a network with a 1000Base-SX backbone.  Which connectors can you use on the backbone?

Explanation

1000Base-SX uses fiber optic cable with the older SC connectors or the small form factor LC connectors.

Submit

13. What is the minimum UTP cable rating for a 10Base-T network?

Explanation

A 10Base-T network operates at up to 10 Mbps. The minimum cable rating that can support this speed is CAT3 cable, which is rated up to 16 Mbps while CAT2 cable is rated at a maximum 4 Mbps.

Submit

14. Which of the following supports the longest transmission distance?

Explanation

10GBase-ER has a maximum transmission distance of 40 kilometers, while 10GBase-SR has a maximum transmission distance of 300 meters, 1000Base-SX a maximum transmission distance of 550 meters, and 10GBase-LR a maximum transmission distance of 10 kilometers.

Submit

15. Your company has a routed network.  You need to extend the network by adding a second router.  What would you use to connect the two routers?

Explanation

The ports on the two routers will be physically and electronically the same medium dependent interface (MDI), therefore, you need a crossover cable to connect the two together.

Submit

16. You work as the network technician for a company that has acquired an adjacent building.  You need to connect the networks, laying the cable in the wiring duct between the two buildings.  Which cable would be most suitable?

Explanation

There could be electromagnetic interference (EMI) in the wiring duct. Fiber optic cable is immune to EMI and would be the best option.

Submit

17. Which of the following fiber-optic standards uses wavelength beams of 1550 nanometers?

Explanation

10GBase-ER uses extra long wavelength beams of 1550 nm.

Submit

18. Which of the following statements regarding 1000Base-TX is true?

Explanation

1000Base-TX uses a minimum of CAT5e UTP cable and has a maximum transmission speed of 1000 Mbps and a maximum transmission distance of 100 meters.

Submit

19. Which of the following fiber-optic standards use wavelength beams of 1310 nanometers?

Explanation

10GBase-LR uses long wavelength beams of 1310 nm.

Submit

20. A patch cable is used to connect which of the following in a token ring network?

Explanation

MAUs are like hubs in a token ring network. Two MAUs are interconnected with a patch cable.

Submit

21. Which of the following statements is true?

Explanation

10GBase-SR has a throughput of up to 10 Gbps while 1000Base-SX has a throughput of up to 1000 Mbps (1 Gbps). However, 10GBase-SR has a maximum transmission distance of up to 300 meters while 1000Base-SX has a maximum transmission distance of up to 550 meters.

Submit

22. Which cable would you need to connect a new host to a 10GBase-SR switch?

Explanation

10GBase-SR uses multimode fiber optic cable that has a maximum transmission distance of 300 meters.

Submit

23. You work on a 1000Base-TX network.  To make full use of the bandwidth offered by 1000Base-TX, which UTP cable should you use?

Explanation

A 1000Base-TX network operates at up to 1000 Mbps. The minimum cable rating that can support this bandwidth speed is CAT5e cable, which is rated at up to 1000 Mbps while CAT5 cable is limited to 100 Mbps.

Submit

24. Which of the following are the most common fiber-optic cable connectors?

Explanation

ST and SC connectors are used for fiber optic cable

Submit

25. You have purchased a new cable modem which was supplied without cables.  You need to connect the cable modem to a 100Base-T switch.  Which of the following cables would you require?

Explanation

You can connect a cable modem to a computer via a switch. However, the cable modem's Ethernet connection is physically and electronically the same as a medium dependent interface-crossover (MDI-X) port on the switch, therefore you need a crossover cable to connect the two. You would also need a RG-6 cable that the cable modem uses to receive its signals. This cable connects to the wall socket, which feeds into the cable from the cable provider.

Submit

26. You work with a 1000Base-SX network.  Which of the following connectors would you expect to find on the network?

Explanation

ST connectors are found on the older Gigabit Ethernet that uses fiber optic cable, such as 1000Base-FX and 1000Base-LX

Submit

27. You want to connect a cable modem to a switch.  Which of the following would you use?

Explanation

The cable modem's Ethernet connection is physically and electronically the same as a medium dependent interface-crossover (MDI-X) port on the switch, therefore, you need a crossover cable to connect the cable modem to the switch, and not a straight-through cable.

Submit

28. Which of the following statements is false?

Explanation

Multi-mode fiber is generally used for short transmission distances while single-mode fiber is used for longer transmission distances. 1000Base-LX with multi-mode fiber has a maximum transmission distance of 550 meters while 1000Base-LX with single-mode fiber has a maximum transmission distance of 2000 meters.

Submit

29. Which of the following connectors would you expect to find on a cable modem?

Explanation

Cable modems use RG-6 co-axial cable and F-Type connectors.

Submit

30. Which cable would you need to connect a new host to a 1000Base-SX switch?

Explanation

1000Base-SX uses single-mode fiber optic cable that has a maximum transmission distance of 550 meters.
