D. Configure the system to use dual channel memory.

A

A.

19
Q

You are in the process of configuring a new computer. The motherboard has four memory slots and supports dual-channel memory. You install two memory modules. When you boot the computer, the BIOS recognizes both modules, but the memory is not configured to run in dual-channel mode.

What should you do?
A. Add continuity modules to unused memory slots.
B. Change the CAS latency to a higher setting.
C. Replace the memory with dual-channel capable memory.
D. Move the modules to the correct motherboard slots.

A

21
Q

If a computer cannot connect to the network, what is the first step in troubleshooting?

A

Check the network cable first. Make sure the RJ45 plug has a solid connection.

22
Q

How many wires does an RJ45 cable contain?

A

8

23
Q

How many wires does an RJ11 cable contain

A

11

24
Q

A standard twisted-pair patch cable that you would use to connect a computer to a switch or RJ45 jack is wired for 568B on each end. That makes it a straight-through cable. What would you need to do in order to connect directly to another computer?

A

if you wanted to connect a computer directly to another computer, you would need to use a crossover cable.

This type of cable is wired for 568B on one end and 568A on the other.

25
Q

What is UTP?

A

Unshielded twisted pair used in RJ45 (CAT-5 - CAT-7)

26
Q

What are some disadvantages of UTP?

A

Max length is 100 meters before signal attenuation occurs.

Outer jacket is made of plastic and has no shielding making it susceptible to interference and wiretapping.

27
Q

True or False

To meet fire code, use plenum-rated cable above drop ceilings and anywhere else necessary.

A

True

28
Q

What is STP?

A

Shielded twisted pair

29
Q

What are Pros and Cons of STP

A

Pros:
Shielded to prevent interference, (EMI) and wiretapping.

Cons:
Higher cost
Must be grounded

30
Q

What is RG-6?

A

Common type of coaxial cable used in a wide variety of residential and commercial applications.

31
Q

What are advantages of Cable over RJ45?

A

Cable is less susceptible to interference. Can be ran longer than RJ45 (CAT-5) before the signal degrades.

32
Q

What are some advantages of Fiber over RJ-6?

A

Fiber can run signals much faster and longer than cable (RJ-6) and RJ45 (CAT-5). No EMI (Interference)
and more secure because it’s difficult to splice.
In addition Fiber can run at speed greater than 1000-Mbps

33
Q

What is the approximate maximum distance for Multimode Fiber cables?

A

600 meters

34
Q

What is the approximate maximum distance for Single-mode Fiber cables?

A

Up to 1000 kilometers
