Question 1:

Which of the following is not considered a system component that can be found inside a computer?

A) CPU

B) RAM

C) PCIe graphics adapter

D) Motherboard

Explanation: Correct Answer is C. System components are essential for the basic functionality of a computer system. Many of the landmarks found on the motherboard can be considered system components, even expansion slots to a degree. What you plug into those slots, however, must be considered peripheral to the basic operation of the system.

Question 2:

Which of the following is a physical memory format installed directly in today’s desktop computer systems?

A) DIMM

B) HDD

C) SSD

D) eMMC

Explanation: Correct Answer is A. Except for DIMMs, all options represent some form of secondary storage.

Question 3:

Which of the following are components that can commonly be found on a motherboard? (Choose all that apply.)

A) Headers

B) Fan connectors

C) Gyroscope

D) Scanner

E) HDD

Explanation: Correct Answer is A, B. Motherboards commonly have headers for lights and buttons and for powering cooling fans. Gyroscopes are most commonly found in mobile devices. Scanners are external devices. Although there might be one or more types of HDD interfaces built into the motherboard, the HDD itself is not.

Question 4:

You are buying optical discs and need to ensure they have large capacity. What suffix indicates that the capacity of an optical disc is roughly twice that of its standard counterpart?

A) DL

B) R

C) RW

D) RE

Explanation: Correct Answer is A. DL stands for double or dual layer. With DVDs, the capacity almost doubles, but with Blu-ray discs, it actually does. R means recordable, and RW and RE are used to designate rewritable or re-recordable.

Question 5:

You are replacing a power supply with a new one. What is the primary characteristic you should look for to ensure all internal components can be supported?

A) Amperage rating

B) 20-pin to 24-pin motherboard adapter

Explanation: Correct Answer is C. Wattage is the unit of output for power supplies. Make sure that the power supply has enough wattage to support all components.

Question 6:

A user has asked you to install a RAID array. Except in the case of RAID 0, which do all types of RAID offer? (Choose two.)

A) Faster read speeds

B) Faster write speeds

C) Redundancy

D) Fault tolerance

E) Ability to restore automatically from tape after a drive failure

Explanation: Correct Answer is C, D. Except for RAID 0, all implementations of RAID offer a way to recover from the failure of at least one drive, which is an example of fault tolerance, through the implementation of some mechanism that stores redundant information for that purpose. Some RAID types offer faster read and/or write performance. RAID 1, for instance, does not guarantee either.

Question 7:

Which of the following types of connectors would you expect to see on the end of a serial cable?

A) DB-9

Question 15:

Which of the following cable types is made with a plastic coating that does not produce toxic fumes when it burns?

A) Plenum

B) Fiber

C) Coaxial

D) UTP

Explanation: Correct Answer is A. The plenum is an air space within buildings used to circulate breathable air for occupants of a building. Fiber, coaxial, and UTP cables are normally enclosed with a PVC plastic coating, which produces toxic fumes if burned. For air ventilation spaces, plenum grade cable is required. All cable types have plenum-rated versions.

Question 24:

Google Docs is an example of what type of cloud service?

A) SaaS

B) IaaS

C) PaaS

D) GaaS

Explanation: Correct Answer is A. Google Docs is software, so it is an example of software as a service (SaaS). IaaS is infrastructure as a service. PaaS is platform as a service. GaaS is not a test objective and is not currently a cloud service type.
