You are using the Performance Monitor on a Windows 7 Professional workstation and make note of the following counters: Memory: Pages/sec 80; Processor: %utilization 90; Physical disk: % disk time 85. Which of the following solutions would overcome the bottleneck indicated by these results?
a) Add a SCSI hard disk drive.
b) Upgrade to a faster processor.
c) Add a second CPU
d) Add RAM
Answer & Explanation: These measurements from Performance Monitor are indicating overuse of virtual memory. Note the heavy paging per second, hard drive usage, and the CPU usage. Adding RAM is the right solution. Answer: Add RAM.
1) A Windows 7 Professional computer is having boot problems. You investigate and decide that the problem may be related to a process being initiated by Internet Explorer. Which one of the following Advanced Options would you choose to correct the problem?
a) Safe Mode with Networking.
b) Safe Mode with Command Prompt.
c) Safe Mode.
d) Enable Boot Logging.
Answer & Explanation: Remember, Safe Mode prevents startup files and most of the drivers from loading. This simplification of the system can give you the chance to troubleshoot and detect needed fixes. Safe Mode with networking will permit internet access. Answer: Safe Mode with Networking.
1) Which device should not be plugged into a UPS?
a) A monitor
b) A laser printer
c) A scanner
d) A modem
Answer & Explanation: UPS devices contain batteries with enough power to run your PC for a few minutes so you can shut it down safely. They are not equipped to handle the power requirements of a laser printer or other high voltage devices, which will exhaust their charge very quickly. Answer: A laser printer
You are evaluating smartphones to be supplied to key employees in your company. You have the selection narrowed down to two models. They are equivalent in all areas except one uses a stylus as opposed to simple touch. Which of the following statements are true? (Choose all that apply.)
a) The stylus based screen uses capacitive technology
b) The touch based screen uses resistive technology
c) The stylus based screen uses resistive technology
d) The touch based screen uses capacitive technology
e) Capacitive screens are preferable if you wear rubber gloves when using them
f) Resistive screens are generally faster and clearer
The correct answer is at the very bottom of this page.
EXPLANATION: The capacitive technology is used in touch based screens. They use the conductive properties of human skin to recognize input. The conductivity makes them more suitable for multi-touch operations like “pinch” object resizing. Their screen is sharper in appearance. If you frequently wear gloves you should opt for the resistive screen as the electrical input is not supplied to a capacitive screen. The resistive screen uses two thin layers separated by micro spacers. This reduces the clarity of the display to a degree as you are viewing through an additional layer. Input is recognized when pressure causes the two layers to make contact. The input pressure can be recognized by touch, but is more accurate with the stylus. They are fractionally slower because of the physical nature of the input and the multi-touch operations are more complicated. However, if you cannot make direct skin to screen contact they will appear non-responsive. Just don’t forget and use a pen as a stylus or you’ll write all over your screen. If you lose the stylus use a toothpick or even your fingernail.
The correct answers are: C) The stylus based screen uses resistive technology, and D) The touch based screen uses capacitive technology.
A POST card:
a) Is used for troubleshooting computer startup problems
b) Terminates the SCSI chain
c) Allows for testing connector pins on the NIC port
d) Is used in biometric authentication
Answer: a
Is used for troubleshooting computer startup problems
A recent Microsoft update is causing any machine that uses the GeForce chipset to display diagonal lines. Your company’s last major PC purchase all use this chipset. You have been on the phone dealing with the customers and walking them through the driver rollback process which takes about 10 min. This has been going on all morning. It is now approaching your lunch hour and the phone rings. What should you do?
a) Let it go to voicemail, this is your lunch hour.
b) Answer and set up a time with the user for after your lunch hour.
c) Advise the customer that everyone is having the problem and therefore call volume is such that they will be handled in order.
d) Listen to the issue as described by the user, then walk him through the process at his pace.
EXPLANATION: For a user there is never a good time to have a computer problem. The fact that there is a problem at all is enough to get a user agitated. Your role here may include pacifying the user then help them work through the problem. Make sure they know that you care and explain as much about the process as you feel is prudent without using slang and jargon. Since it is not yet your lunch hour, handle the call even if you risk cutting a little into your lunch time. Although you have been handling several calls, nothing in the question indicates that you have a back-log and that is why neither B nor C are applicable to the situation as described.
The correct answer is: D) Listen to the issue as described by the user, then walk him through the process at his pace.
