Lesson 2
Ethernet Standards and Cable Types

The CCNA Exam will Hammer You with Questions About Ethernet… so this course breaks down everything you need to know about cable types. this is also crucial for setting up and running a network in the real world.

* The Need For And Operation of CSMA/CD
* Ethernet Types And Standards
* Pins And Transmissions
* Crosstalk
* Cable Types
* Ethernet Addressing

1. 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

2. 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

3. 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.

4. 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

5. 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.

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

7. 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

8. 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

9. 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

10. What type of cable is used to make an Ethernet connection between a host and a LAN switch?
• console
• rollover
• crossover
• straight-through

11. 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

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. 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
• decimal encoded data transmission

Refer to the exhibit. What type of cable connects the two routers together without any intermediary device?
• console
• rollover
• crossover
• straight-through

15. 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
