CCNA 1 Module 3 Exam Solutions

Cisco’s exams can be a lot of hard work- we know. But the worst thing you can do to yourself is to simply look up the answers to exam questions. Not only do you not learn anything- but you’re hurting your future in the process.

Instead, shouldn’t you get a helpful hint and get pointed in the right direction of where to look for an answer? That way, you can keep your dignity, hopes for the future, and of course your grade. The questions below are from the CCNA 1 module 3 exam- but instead of straight answers, we reason out why the answers are correct. If any type of math or decision making is involved, we leave that up to you (But we will of course give you the resources you need to complete the question.)


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

A) is stiffer than STP

B) is less expensive than fiber

C) is easier to install than coaxial

D) provides longer distances than coaxial provides

E) is less susceptible to outside noise sources than fiber is

More Info: A Brief Overview Of Networking Media

Explanation: A is incorrect, since we don’t ever recall the stiffness of a cable being a factor in cable advantages. B is true, since fiber is a newer technology, that likewise is more expensive to produce. C is also true, since coaxial can be a pain to install- unlike UTP cable. D and E are both untrue since coaxial provides longer distance, and fiber isn’t susceptible to most outside interference.


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

A) lower cost

B) easer to install

C) allows longer distances

D) less effected by external signals

E) easier to terminate the cable ends

More Info: A Brief Overview Of Networking Media

Explanation: A is incorrect, since fiber-optic media is still fairly expensive. And although it is fairly easy to install, UTP is much easier- B is also incorrect. C is true since we use modulated light waves to transmit data- which can travel vast distances as compared to copper media. D is also true for the same reason- we aren’t using electric signals in fiber optic media, which means no electro-magnetic interference. E is untrue, since UTP cable doesn’t need to be terminated at all.


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

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

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

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

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

E) 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.

More Info: (None)

Explanation: Since the type of NIC doesn’t necessarily dictate operation speed, A is not correct. B is also incorrect, since both use expansion slots. C is incorrect, since the NIC again does not necessarily dictate the network type. D is true, since we know that wireless signals need an access point, and Ethernet NICs connect to hubs/switches. Finally, E is incorrect since we aren’t limited to fiber optic media on Ethernet NICs.


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

A) 802.11

B) 802.11a

C) 802.11b

D) 802.11g

More Info: A Brief Overview Of Networking Media

Explanation: From reading the above article, we know that only one of the above standards operates at 5 GHZ. Click the above link to learn more.


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

A) No changes are required.

B) Each host will require a new IP address.

C) Each host will require an appropriate NIC or adapter.

D) Each host will require that the operating system be upgraded.

More Info: (None)

Explanation: A is incorrect since we will indeed need to change the NIC. B is incorrect since we don’t necessarily need to rearrange our IP addresses. C is correct, since we will need to obtain a wireless NIC as opposed to the Ethernet NIC. D is also incorrect since the operating system has no influence on the question at hand.


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

A) A=straight, B=rollover, C=crossover

B) A=rollover, B=crossover, C=straight

C) A=crossover, B=straight, C=straight

D) A=crossover, B=straight, C=rollover

E) A=straight, B=crossover, C=rollover

F) A=rollover, B=straight, C=crossover

More Info: The Difference Between Straight Through, Crossover, And Rollover Cables

Explanation: From reading the above article, we know that the above pinouts only match one of the listed answers. Read the above article for more information.


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

A) type of system bus

B) motherboard model

C) distance of cable run

D) speed of transmission

E) computer manufacturer

More Info: A Brief Overview Of Networking Media

Explanation: A and B are both incorrect since they do not relate to the wiring process of a network. C and D are both factors in the process, so they are correct. E is incorrect, for the same reason A and B were- it does not have a part in the wiring process.


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

A) 10BASE2

B) 10BASE5

C) 100BASE-T

D) 100BASE-FX

E) 1000BASE-CX

More Info: A Brief Overview Of Networking Media

Explanation: There is a handy diagram in the above article that will explain the distance implementations of the above choices. Click the above link for more information.


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

A) when configuring a router

B) when connecting a host to a host

C) when connecting a switch to a router

D) when connecting one switch to another switch

More Info: The Difference Between Straight Through, Crossover, And Rollover Cables

Explanation: The above article explains which instance a straight-through cable is used- refer to it for further information.


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

A) console

B) rollover

C) crossover

D) straight-through

More Info: The Difference Between Straight Through, Crossover, And Rollover Cables

Explanation: The above article explains which cable should be used in this instance- refer to it for further information.


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

A) light patterns

B) electrical voltages

C) controlled air pulses

D) mixed media impulses

E) magnetized fluid wave

F) modulated electromagnetic waves

More Info: A Brief Overview Of Networking Media

Explanation: The above article explains that light patterns, electrical voltages, and modulated electromagnetic waves are all used for communication. Thus, A, B, and F are correct.


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

A) shielding

B) magnetism

C) cancellation

D) insulation

E) properly grounded connections

F) RJ-45 connectors

More Info: A Brief Overview Of Networking Media

Explanation: We know from the above article that EMI and RFI can both be reduced via cancellation- particularly, in the twisting of the wires inside the cable.


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

A) twisted pair cable

B) T style connectors

C) baseband transmission

D) 10 gigabits per second data rate

E) 10 megabits per second data

F) decimal encoded data transmission

More Info: A Brief Overview Of Networking Media

Explanation: The above article explains that we can break down what a cable’s specifications are through its name. The 10 means that it may transmit 10 megabits per second- E is correct. The T means it is a twisted pair cable- A is correct. Base means that it is a baseband transmission- so C is also correct.


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

A) console

B) rollover

C) crossover

D) straight-through

More Info: The Difference Between Straight Through, Crossover, And Rollover Cables

A) RJ-11

B) RJ-12

C) RJ-45

D) DB-8

E) DB-9

F) DB-10

More Info: (None)

Explanation: Since the above is fairly basic terminology, we should know that RJ-45 and DB-9 are both correct. Thus, C and E are the correct choices.
