Q
  1. You are troubleshooting the startup of a system that seems to need you to enter the date and time every time the system boots up. What should you do?

(A) Ensure memory modules are seated properly
(B) Ensure the video card is seated properly.
(C) Replace the CMOS battery
(D) Flash the BIOS

A

(C) Replace the CMOS battery

When you boot a computer that prompts for the date and time, this is a great indication that the computer is forgetting the information stored in CMOS. This is most likely due to the battery needing to be replaced on the motherboard.

Q
  1. You are the lead consultant at your company. Your customer is looking to improve the performance of one of the video editing systems by installing a new graphics card. Which of the following video cards would be the better performing video card to purchase?

(A) PCI
(B) PCIe x16
(C) AGP x8

A

(B) PCIe x16

PCIe is the newer bus architecture that has the better transfer rates and should be used if PCIe slots are available. PCIe in this case has a transfer rate of 4 GBps (16 x 250 MBps), while AGP 8x would have a transfer rate of 2 GBps.

Q
  1. Your office has some older Pentium class systems that contain AGP slots. Your manager asks about the benefit of AGP. How would you respond?

(A) AGP slots have a direct path to the processor to help increase performance of AGP devices
(B) AGP cards run at 33 MHz
(C) AGP runs at 66 MHz and gets access to the processor through the PCI bus
(D) AGP stands for Advanced Graphics Port and is used to install additional video memory

A

(A) AGP slots have a direct path to the processor to help increase performance of AGP devices

The AGP slot runs at 66 MHz and has a direct between the slot and the processor so that information will not have to travel through one of the slower buses. AGP stands for Advanced Graphics Port, and is used to install a video card, not video memory.
