CompTIA A+ 220-801 Practice Exam Question 15

CompTIA A+ 220-801 Practice Exam Question 15
Where would you go to start, stop, or restart services?

A. Computer Management
B.
Task Manager
C. Performance Monitor
D. MMC

Answers: B
Explanations

The PC air intakes are probably clogged with cement dust. This will stop fresh, cool air from entering the PC and cause the CPU to overheat. That’s why the system won’t reboot immediately because the CPU needs some time to cool down. You should install a filter in front of the PC air intake and instruct the customer to clean the filter often. While you are working on the computer, you should clean out the inside of the system and vacuum out the exhaust of the power supply (without opening the power supply of course). If the PC had a virus, that might cause it to lock up or shut down, but you would be able to reboot the computer right away. Plus, there would probably be other indicators of a virus. The CPU heat sink could be an issue and could cause the same results, but it is less likely. Companies often buy computers from popular manufacturers such as Dell and HP; these computer manufacturers spend a lot of time designing their heat sink/fan combinations to work with the CPU. If the power supply was underrated, it would cause intermittent shutdowns, but not lockups. Nothing in the scenario would lead you to believe that the computer uses so many powerful components as to make the power supply underrated.

CompTIA A+ 220-801 Practice Exam Question 5
Windows service packs are ___________.

A. A new version of the operating system
B. Resource Kit utilities
C. Compilations of software updates and patches
D. Driver updates

Answers: A
Explanations:
Internet Explorer (or any other web browser) is normally used to configure a router. It’s sometimes referred to as romming into the router because the configuration program is stored in the ROM chip of the router. You can type the IP address of the router into the Windows Explorer address bar, but that will simply open an IE (or other browser) tab. The Device Manager is where you enable and disable devices and install, update, and roll back drivers for devices. Msconfig is used to modify how the computer boots and to enable/disable programs and services.
