This Exam contains:

-Guarantee passing score -15 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation

Question 1: What is the IEEE?

Answer:

Institute of Electrical and Electronics Engineers

Question 2: Pros/Cons of UTP cabling

Answer:

-Lower cost than fiber-optic -Shorter maximum distance than fiber-optic -can be vulnerable to EMI (Electromagnetic interference) -RJ45 ports used with UTP are cheaper than SFP ports -Emit (leak) a faint signal outside of the cable, which can be copied (=security risk)

Question 3: What is an SFP?

Answer:

Small Form-factor Pluggable

Question 4: Ethernet standard speeds

Answer:

10mbps - Ethernet - 802.3i 10BASE-T 100m 100mbps - Fast Ethernet - 802.3u 100BASE-T 100m 1gbps - Gigabit Ethernet - 802.3ab 1000BASE-T 100m

10gbps - 10 Gig Ethernet - 802.3an 10GBase-T 100m

Question 5: Pros/Cons of Fibre Optic

Answer:

-Higher cost than UTP -Longer maximum distance than UTP -No vulnerability to EMI -SFP ports are more expensive than RJ45 ports (single-mode is more expensive than multimode) -Does not emit any signal outside of the cable (=no security risk)

Question 6: Single Mode Fiber

Answer:

-Long-range communication -Over 80 km without additional processing -Expensive light source (laser beams) -Allows longer cables than oth UTP and multimode fiber Question 7: Your company needs to connect many end hosts to a switch which is in a wiring cabinet on the same office floor as the hosts. What kind of cable should they use?

a) UTP

b) Single-mode fiber

c) Multimode fiber

Answer:

a) UTP

Question 8: IEEE Ethernet Standard?

Answer:

802.3 Question 9: A switch has the following indication over its network interfaces: 10/100/1000Base-T Ports (1-24)-Ports are Auto-MDIX 9 11 Link/Act-13-Spd* 15 What would happen if you connect it to an identical switch with a straight-through cable?

a) They would operate normally.

b) They would operate at a reduced speed.

c) They would be unable to communicate.

Answer:

a) They would operate normally.

Question 10: UTP Cables how many pairs?

Answer:

10BASE-T = 2 pairs (4 wires) 100BASE-T = 2 pairs (4 wires) 1000BASE-T = 4 pairs (8 wires) 10GBASE-T = 4 pairs (8 wires) Question 11: Your company wants to connect switches in two separate buildings that are about 150 meters apart. They want to keep costs down, if possible. What kind of cable should they use?

a) UTP

b) Single-mode fiber

c) Multimode fiber

Answer:

c) Multimode fiber

Question 12: Multi-mode fiber

Answer:

-Fiber for transmitting Multiple rays of regular light from LEDS.-Popular fiber type with larger diameter -slower -shorter distance -less expensive

Question 13: Your company wants to connect two offices that are about 3 kilometers apart. They want to keep costs down if possible. Which kind of cable should they use?

a) UTP

b) Single-mode fiber

c) Multimode fiber

Answer:

b) Single-mode fiber

Question 14: UTP cables use which type of connector?

Answer:

RJ-45 - protects against EMI Question 15: You connect two old routers together with a UTP cable, however data is not successfully sent and received between them. What could be the problem?

a) They are connected with a straight-through cable.

b) They are connected with a crossover cable.

c) They are operating in Auto MDI-X mode.

Answer:

a) They are connected with a straight-through cable.
