Posted February 21st, 2007 by admin
1. RJ-45 connectors are used with ?
coax
Fiber-optic
1000Base-LX
10BASE-T
Correct answer: 10BASE-T
2. 10Base-2 is also reffered too as ?
Thicknet
Thinnet
unshielded twisted-pair
Category 3
Correct answer: Thinnet
3. 1000Base-SX is a Fiber-optic cable.
True False
Correct answer: True
4. A BNC barrel connector, is used to connect two cables together, and increase the signal strength.
True False
Correct answer: False
Explanation: It is better to use one continuous length of cable, as these connectors weaken the signal strength.
5. The following is an ?
BNC barrel connector
SC connector
ST connector
RJ-45 connector
Correct answer: ST connector
6. The following is an ?
RJ-45 connector
SC connector
ST connector
BNC connector
Correct answer: SC connector
7. Token Ring networks usually use coax cables.
True False
Correct answer: False
8. 1000Base-T is not a Category 5 cable.
True False
Correct answer: False
9. A BNC connector is for ?
coaxial
Fiber-optic
Category 5
10Base-T
Correct answer: coaxial
Explanation: A BNC connector for coaxial cables. These are either soldered, or crimped to the end of the cable.
10. SC and ST connectors can be used in the same network with the use of adapters or couplers.
True False
Correct answer: True
11. This is an ?
BNC connector
SC connector
ST connector
RJ-45 connector
Correct answer: BNC connector
12. The maximum segment length of 100Base-FX at half duplex is ?
200 meters
412 meters
1000 meters
2000 meters
Correct answer: 412 meters
13. The maximum transfer speed of 10Base-5 is ?
100 Mbps
2 Mbps
1 Gbps
10 Mbps
Correct answer: 10 Mbps
14. Fiber networks use what kind of connectors ?
SC
BNC
RJ-45
RJ-11
Correct answer: SC
Explanation: In the North America, most cables use a square SC connector that slides and locks into place when inserted into a node or connected to another fiber cable, Europeans use a round ST connector instead.
15. RJ-45 connectors resemble telephone RJ-11 connectors, but are larger and house 12 wires.
True False
Correct answer: False
Explanation: RJ-45 connectors are used with 10-100BaseT cables. These resemble telephone RJ-11 connectors, but are larger and house 8 wires while RJ-11 house 4 or 6 wires. They are connected to the cable by crimping.
16. Standard telephone cable connectors, usually have 4-6 wires.
True False
Correct answer: True
17. STP cable protects signals from cross signaling that can result from other, nearby cables.
True False
Correct answer: True
18. The maximum segment length of 10Base-5 is ?
500 m
100 m
2000 m
187 m
Correct answer: 500 m
19. SC and ST connectors offer the same features as far as distance and reliability.
True False
Correct answer: True
20. The following is an ?
BNC connector
SC connector
ST connector
RJ-45 connector
Correct answer: RJ-45 connector
