CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 481:

  A remote user called the help desk to report a notification indicating there is limited or no connectivity. The user can access local file folders and other local machines but none of the organization's servers or network items. Web pages do not appear to function either. Which of the following is the MOST likely cause of the issue?

  A. The user's internet connection is down.

  B. The user's domain account is locked out.

  C. The user's switch has stopped working.

  D. The user's IP address needs to be renewed.

  Correct Answer: A

  Based on the information provided in the scenario, the most likely cause of the issue is that the user's internet connection is down (option A). This would explain why the user is unable to access any of the organization's servers or network items and why web pages are not functioning. However, since the user can still access local file folders and other local machines, it suggests that their local network is still functioning. The user can access local file folders and other local machines but none of the organization's servers or network items, indicating that the issue is with the user's internet connection, not with the user's domain account, switch, or IP address. When a user receives a notification indicating that there is limited or no connectivity, it means that their device is unable to establish a connection to the network. In this scenario, the user can access local file folders and other local machines but is unable to access any of the organization's servers or network items and web pages are not functioning. This suggests that the issue is with the user's internet connection. An internet connection allows a device to communicate with other devices and servers outside of its local network. If the internet connection is down or not functioning properly, the device will be unable to access any resources outside of its local network. This would explain why the user in this scenario can still access local resources but is unable to access any of the organization's servers or network items.

• Question 482:

  A user takes a tablet to a technician because the cursor on it keeps drifting. The technician notices the screen does not appear to be damaged.

  Which of the following is the MOST likely cause of the cursor issue?

  A. The screen is physically damaged.

  B. The screen rotation is incorrect.

  C. The touch-pen battery is depleted.

  D. The screen needs to be recalibrated.

  Correct Answer: D

  CompTIA: "On a laptop, if touchpad sensitivity is too high, typing can cause vibrations that move the cursor. Examples include the pointer drifting across the screen without any input or a 'ghost cursor' jumping about when typing. Install up-todate drivers and configure input options to suit the user. Many laptops now come with a Fn key to disable the touchpad.

  If you can rule out simple hardware causes, unresponsive or inaccurate touch input can be an indication of resources being inadequate (too many open apps) or badly written apps that hog memory or other resources. A soft reset will usually fix the problem in the short term."

• Question 483:

  A user failed to gain access to a building's entrance after security measures at the entrance were upgraded last week. The company implemented the 13.56MHz frequency short band, and users can now utilize their mobile devices to authenticate. Which of the following has to be enabled for the mobile device to authenticate?

  A. Bluetooth

  B. Biometrics

  C. NFC

  D. PIN

  Correct Answer: C

  NFC (Near Field Communication) is a technology used for short-range wireless communication between devices, typically used for contactless payments and authentication. In this scenario, the 13.56MHz frequency short band was implemented, and users can authenticate using their mobile devices, which requires NFC to be enabled on the device.

• Question 484:

  A technician needs to improve a workstation's overall response time for frequently used applications and data without removing the current hard drive. Which of the following storage devices should the technician install to BEST accomplish the objective?

  A. M.2

  B. SAS

  C. HDD

  D. SCSI

  Correct Answer: A

  Installing an M.2 SSD will improve a workstation's overall response time for frequently used applications and data without removing the current hard drive. M.2 drives are faster and more efficient than traditional hard drives, making them a good option for increasing overall performance.

• Question 485:

  A technician is setting up a device to use two-factor authentication. Which of the following meets this requirement?

  A. Thumbprint/retinal scan

  B. Password/password

  C. Password/thumbprint

  D. Password/PIN

  Correct Answer: C

  Two-factor authentication (2FA) is a security process that requires users to provide two different authentication factors to verify their identity. This means that in addition to providing something they know (such as a password or PIN), they

  must also provide something they have (such as a smart card or token) or something they are (such as a fingerprint or retinal scan).

  In this case, the correct answer would be C. Password/thumbprint. This option meets the requirement for two-factor authentication because it combines two different types of authentication factors: something the user knows (the password)

  and something the user is (the thumbprint). The other options do not meet the requirement for 2FA because they either use only one type of authentication factor (A and D) or use two instances of the same type of factor (B).

• Question 486:

  A technician goes to a classroom to troubleshoot a projector that occasionally powers off. The technician recreates the issue and notices the projector will not power back on until approximately 15 minutes have passed. After 15 minutes of being powered on. the projector shuts off again. Which of the following should the technician perform NEXT to resolve the issue?

  A. Clean the filter.

  B. Adjust the standby timeout.

  C. Check the power cable connection.

  D. Replace the bulb.

  Correct Answer: A

  Based on the given information, it seems that the projector is experiencing issues with overheating or a faulty power supply. The fact that it shuts off and cannot be turned back on until it has cooled down for 15 minutes suggests that the projector is overheating or there is a problem with the power supply. Therefore, the next logical step would be to clean the filter to ensure proper ventilation and airflow, as a dirty filter can cause overheating.

• Question 487:

  A user's computer is not receiving a network connection. The technician confirms that the connection seems to be down and looks for the user's port on the patch panel. The port and patch panel are not labeled. Which of the following network tools should the technician use to identify the port?

  A. Network tap

  B. Punchdown tool

  C. Toner probe

  D. Crimper

  Correct Answer: C

  Toner Probe Many cable testers also incorporate the function of a toner probe, which is used to identify a cable from within a bundle. This may be necessary when the cables have not been labeled properly. The tone generator is connected to the cable using an RJ45 jack and applies a continuous audio signal on the cable. The probe is used to detect the signal and follow the cable over ceilings and through ducts or identify it from within the rest of the bundle.
