CCNA 3 Networking Basics (Version 3.1)

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.

-
Refer to the exhibit. Which answer correctly identifies the pinout of the UTP cables labeled Cable A, Cable B, and Cable C?

  -A=straight, B=rollover, C=crossover
  -A=rollover, B=crossover, C=straight
  -A=crossover, B=straight, C=straight
  *•*A=crossover, B=straight, C=rollover
  -A=straight, B=crossover, C=rollover
  -A=rollover, B=straight, C=crossover
