   A technician is inspecting a projector that is displaying fuzzy images. Which of the following actions would provide the BEST solution?

   • AAdjusting the lens
   • BChanging the filter
   • CReplacing the video cable
   • DReseating the lamp

   Show answer

   Answer: A

   Explanation

   Based on the symptoms described, the BEST solution would be to reseat the lamp. Fuzzy images can be caused by a variety of issues, but a common cause is a lamp that is not securely seated or is nearing the end of its life. By reseating the lamp, the technician can ensure that it is properly connected and providing sufficient light to produce a clear image. Adjusting the lens might help if the image is out of focus, but if the image is fuzzy, it is likely that the lamp is the root cause of the issue. Changing the filter and replacing the video cable may help if those components are faulty, but they are less likely to be the cause of fuzzy images than an improperly seated or failing lamp.

   An end user discovered that the touch-screen features on a Windows device have stopped working. Which of the following should a technician check?

   • APerformance monitor
   • BTablet/PC settings
   • CSystem configuration
   • DDisplay settings

   Show answer

   Answer: B

   Explanation

   B. Tablet/PC settings A technician should check the tablet/PC settings as this is likely to be the cause of the touch-screen features not working. Windows devices have built-in settings for touch-screen features, such as the sensitivity and touch mode. Checking these settings can help determine if there are any configuration changes that could have resulted in the touch-screen features not working. The technician should go to the Control Panel and look for a section on the tablet/PC settings. Here, the technician can adjust the touch-screen settings and calibrate the touch screen, if necessary. If the touch-screen settings are correct, the technician may need to look into other issues, such as a hardware failure or software glitch.

4. Question 624 · 624 in bank

   A help desk technician has been tasked with installing an IP phone in a small office with an unmanaged switch. When connected to an RJ45 receptacle, the phone does not boot. Which of the following is the QUICKEST way to resolve this issue?

   • AUpgrade the Ethernet cable to the latest specification.
   • BReplace the phone.
   • CInstall a PoE injector.
   • DChange ports on the switch.

   Show answer

   Answer: C

   Explanation

   The question asks for the QUICKEST way to RESOLVE this issue. It is a unmanaged switch in a SOHO and IP phones need POE to boot. We do not know if the switch has other ports capable of POE, but due to the environment it is in and type of switch, it very well may not. Disregarding that fact, the only answer out of the given choices, that guarantees the QUICKIEST and RESOLUTION (resolves), is a POE injector. Changing ports does not guarantee it will actually RESOLVE the issue, but it does fulfill the QUICKIEST, but thats not what the question asks.
