What are three factors to consider when purchasing a replacement motherboard?
The new motherboard must come from the same manufacturer as the existing motherboard.
The socket and chipset on the new motherboard must match the existing CPU.
The new motherboard must support the same UEFI BIOS as the previous motherboard.
Which factor can limit the amount of data that the CPU can receive and process at one time?
the size of the CPU cache memory
Which type of optical drive supports the greatest amount of storage and is able to read and write CDs, DVDs, and Blu-Ray media?
DVD-RW
Give a probable cause to the computer or peripherial problem:
The monitor is blank after installing a PCle video card.
The computer runs more slowly after installing a dual-core CPU.
Network shared drives are no longer accessible.
The computer does not start and no beeps are heard.
The computer time must be reset after each reboot.
The card may require auxiliary power. — The monitor is blank after installing a PCle video card.
The BIOS firmware needs to be updated. — The computer runs more slowly after installing a dual-core CPU.
The built-in NIC may have failed. — Network shared drives are no longer accessible.
The POST process is not executing on startup. — The computer does not start and no beeps are heard.
The CMOS battery may be loose or drained. — The computer time must be reset after each reboot.
A help desk technician receives a call from a user describing an issue with a computer. The user states that the computer will not power on, that it only makes a beeping sound. Why does the technician ask the user to restart the system and count how many beeps the computer makes?
Different numbers of beeps can indicate different types of hardware issues discovered during POST.
What is an example of an active cooling solution for a desktop PC?
installing case and CPU cooling fans
What is a consequence of a computer not having enough RAM memory installed?
Data may be swapped between the RAM and the slower hard drive more frequently.
Which type of power supply is the most commonly used and provides a separate power connection in order to directly power the CPU?
ATX12V
Which function is incorporated into some Intel CPUs that enables a single CPU to perform as though two CPUs are installed?
Hyper-Threading (Various CPU manufacturers complement their CPU with performance-enhancing features. For instance, Intel incorporates Hyper-Threading to enhance the performance of some of their CPUs. With Hyper-Threading, multiple pieces of code (threads) are executed simultaneously in the CPU. To an operating system, a single CPU with Hyper-Threading performs as though there are two CPUs when multiple threads are being processed. AMD processors use HyperTransport to enhance CPU performance. HyperTransport is a high-speed connection between the CPU and the Northbridge chip.)
Which three types of external ports can be used to connect an external storage device to a computer?
Thunderbolt
USB
eSATA
Which three computer components require separate cabling for power?
video graphics cards
internal SATA hard drives
case and CPU fans
Which member of the DDR SDRAM family has the fastest clock rate and consumes the least amount of power?
DDR4 SDRAM
What is one function that the user can accomplish with the UEFI/BIOS
set passwords to allow for access to the BIOS
How can a hard drive that is using an MBR be partitioned in order to support additional logical drives?
Make one primary partition an extended partition to contain the logical drives.
A company purchases 15 USB flash drives to use for data analysis training for company accountants. The data analysis training requires that actual company data be stored on the drives, so a secure method of erasing the data is needed before the flash drives can be reused for other training classes. What method should the IT technicians use to ensure that the data on the USB flash drives cannot be recovered?
a quick formatting utility to overwrite the data
