CCNA 1 Module 3 V3.1 Answers

1. What factors should be considered when selecting the appropriate cable for connecting a PC to a network? (Choose two.)

type of system bus

motherboard model

distance of cable run

speed of transmission

computer manufacturer

 

2. What are two advantages of using UTP cable in a networking environment? (Choose two.)

is stiffer than STP

is less expensive than fiber

is easier to install than coaxial

provides longer distances than coaxial provides

is less susceptible to outside noise sources than fiber is

 

3. A company is converting a cabled LAN to a wireless Ethernet LAN. What must be changed on every host on the network?

No changes are required.

Each host will require a new IP address.

Each host will require an appropriate NIC or adapter.

Each host will require that the operating system be upgraded.

 

4. What is the difference between a wireless NIC and an Ethernet NIC?

The Ethernet NIC operates at 100 Mbps, whereas a wireless NIC operates at 10 Mbps.

The Ethernet NIC uses a PCI expansion slot, and a wireless NIC cannot use an expansion slot.

The wireless NIC uses CSMA/CA, whereas a Ethernet NIC uses token passing as an access method.

The wireless NIC associates to an access point, and an Ethernet NIC attaches to a hub or switch using a cable.

The Ethernet NIC attaches to a hub or a switch using only fiber cabling, and a wireless NIC attaches to a wireless antenna using air as a network medium.

 

5. Select the characteristics specified by 10BaseT. (Choose three.)

twisted pair cable

T style connectors

baseband transmission

10 gigabits per second data rate

10 megabits per second data rate

decimal encoded data transmission

 

6. What type of cable is used to make an Ethernet connection between a host and a LAN switch?

console

rollover

crossover

straight-through

 

7. Which wireless standard operates in the 5 GHZ transmission range and is capable of 54 Mbps of data throughput?

802.11

802.11a

802.11b

802.11g

 

8. Which of the following are used for data communication signals? (Choose three.)

light patterns

electrical voltages

controlled air pulses

mixed media impulses

magnetized fluid wave

modulated electromagnetic waves

 

9. Which cable connectors are used to connect a cable from a router's console port to a PC? (Choose two.)

RJ-11

RJ-12

RJ-45

DB-8

DB-9

DB-10

 

10.

Refer to the exhibit. What type of cable connects the two routers together without any intermediary device?

console

rollover

crossover

straight-through

 

11. When is a straight-through cable used in a network?

when configuring a router

when connecting a host to a host

when connecting a switch to a router

when connecting one switch to another switch

 

12. What does UTP cable rely on to reduce signal degradation caused by EMI and RFI?

shielding

magnetism

cancellation

insulation

properly grounded connections

RJ-45 connectors

 

13. What are two advantages of using fiber-optic cabling instead of UTP? (Choose two.)

lower cost

easer to install

allows longer distances

less effected by external signals

easier to terminate the cable ends

 

14. Which Ethernet implementation requires the signal on the media to be boosted at a maximum distance of 100 meters?

10BASE2

10BASE5

100BASE-T

100BASE-FX

1000BASE-CX

 

15.
