CompTIA 220-1102 Online Questions & Answers

• Question 311:

  Which of the following often uses an SMS or third-party application as a secondary method to access a system?

  A. MFA
  B. WPA2
  C. AES
  D. RADIUS
  A. MFA

  ---

  Explanation

  MFA (Multi-Factor Authentication) is a security measure that often uses an SMS or third-party application as a secondary method to access a system. MFA requires the user to provide two or more pieces of evidence to prove their identity, such as something they know (e.g., password), something they have (e.g., phone), or something they are (e.g., fingerprint)2. WPA2 (Wi-Fi Protected Access 2) is a security protocol for wireless networks that does not use SMS or third-party applications. AES (Advanced Encryption Standard) is a symmetric encryption algorithm that does not use SMS or third-party applications. RADIUS (Remote Authentication Dial-In User Service) is a network protocol that provides centralized authentication and authorization for remote access clients, but does not use SMS or third-party applications.

• Question 312:

  A user is unable to log in to a workstation. The user reports an error message about the date being incorrect. A technician reviews the date and verifies it is correct, but the system clock is an hour behind. The technician also determines this workstation is the only one affected.

  Which of the following is the most likely issue?

  A. Time drift
  B. NTP failure
  C. Windows Update
  D. CMOS battery
  A. Time drift

  ---

  Explanation

  Time drift occurs when the internal clock of a computer is not properly synchronized, often leading to discrepancies like being an hour behind. In this case, the workstation is the only device affected, indicating that it's likely a local issue. Time

  drift can happen if the system clock isn't syncing properly with an NTP (Network Time Protocol) server or if automatic daylight savings adjustments aren't enabled. It's less likely to be a CMOS battery issue since the technician has already

  verified the correct date and the system clock isn't completely reset (which is what happens when the CMOS battery fails).

• Question 313:

  A technician is troubleshooting an issue on a PC that has low disk space. Which of the following Control Panel utilities should the technician most likely use to investigate and remediate the issue?

  A. Internet Options
  B. System
  C. Programs and Features
  D. Device Manager
  C. Programs and Features

  ---

  Explanation

  The Programs and Features utility allows users to view, modify, or uninstall applications that may be consuming excessive disk space. This is the best option when addressing low disk space issues.

  Option A: Internet Options, Incorrect. This controls browser settings and has no impact on disk space.

  Option B: System, Incorrect. System settings provide general system information but do not manage disk space.

  Option D: Device Manager, Incorrect. Device Manager is used for managing hardware devices, not disk space.

  Additional Troubleshooting Steps:

  Use Disk Cleanup to remove temporary files.

  Check the Downloads folder and delete unused files.

  Move data to external or cloud storage.

• Question 314:

  A user reports an issue when connecting a mobile device to Bluetooth. The user states the mobile device's Bluetooth is turned on. Which of the following steps should the technician take NEXT to resolve the issue?

  A. Restart the mobile device.
  B. Turn on airplane mode.
  C. Check that the accessory is ready to pair.
  D. Clear all devices from the phone's Bluetooth settings.
  C. Check that the accessory is ready to pair.

  ---

  Explanation

  The first step in troubleshooting a Bluetooth connection issue is to check that the accessory is ready to pair with the mobile device. Some accessories may have a button or a switch that needs to be pressed or turned on to initiate pairing mode. If the accessory is not ready to pair, the mobile device will not be able to detect it.

• Question 315:

  Which of the following filesystem types does macOS use?

  A. ext4
  B. exFAT
  C. NTFS
  D. APFS
  D. APFS

• Question 316:

  Which of the following is MOST likely used to run .vbs files on Windows devices?

  A. winmgmt.exe
  B. powershell.exe
  C. cscript.exe
  D. explorer.exe
  C. cscript.exe

  ---

  Explanation

  A .vbs file is a Virtual Basic script written in the VBScript scripting language. It contains code that can be executed within Windows via the Windows-based script host (Wscript.exe), to perform certain admin and processing functions.

  Cscript.exe is a command-line version of the Windows Script Host that provides command-line options for setting script properties. Therefore, cscript.exe is most likely used to run .vbs files on Windows devices.

• Question 317:

  A SOHO has had several issues with various unauthorized devices consuming the network's bandwidth. There are only four network devices that are authorized to access the Internet as well as the local LAN's resources. Which of the following security implementations would MOST likely help disable network access to the unauthorized devices?

  A. Using complex passwords
  B. Disabling the use of static IP addresses
  C. Disabling ports
  D. MAC filtering
  D. MAC filtering

• Question 318:

  A client recently upgraded their Windows 10 machine to Windows 11. The client reports the following message displays when turning the computer on: "Error loading operating system." Which of the following should a technician do first to troubleshoot this issue?

  A. Disable the Secure Boot feature.
  B. Use the automated startup recovery.
  C. Format the drive.
  D. Resize the boot partition.
  B. Use the automated startup recovery.

  ---

  Explanation

  The "Error loading operating system" message in Windows typically indicates a problem with the boot process. This could be due to corrupted system files, boot configuration data (BCD) errors, or issues with the hard drive. Windows has a

  built-in automated startup recovery tool designed to diagnose and fix these types of problems. It attempts to automatically find and repair issues that are preventing Windows from starting correctly.

  Here's why the other options are not the best first step:

  Option A: Disable the Secure Boot feature: Secure Boot is a security feature that helps prevent malware from loading during startup. While it can sometimes cause issues with incompatible hardware or software, it's unlikely to be the primary

  cause of this error after a Windows upgrade.

  Option C: Format the drive: Formatting the drive should be a last resort as it will erase all data on the hard drive.

  Option D: Resize the boot partition: Resizing the boot partition is a complex task and not usually necessary to fix a boot error.

  Troubleshooting Steps:

  Use the automated startup recovery:

  If automated repair fails, try other options from the Advanced Startup Options menu:

• Question 319:

  A support specialist needs to decide whether to install a 32-bit or 64-bit OS architecture on a new computer. Which of the following specifications will help the specialist determine which OS architecture to use?

  A. 16GB RAM
  B. Intel i7 CPU
  C. 500GB HDD
  D. 1Gbps Ethernet
  A. 16GB RAM

  ---

  Explanation

  The amount of RAM is the key factor in choosing a 32-bit vs. 64-bit OS:

  A 32-bit OS can only address up to 4GB of RAM.

  A 64-bit OS is required for 16GB RAM or more to fully utilize the memory.

  Option B: Intel i7 CPU, Incorrect. Most modern CPUs support both 32-bit and 64-bit OS.

  Option C: 500GB HDD, Incorrect. Hard drive size does not determine OS architecture.

  Option D: 1Gbps Ethernet, Incorrect. Network speed has no relation to OS architecture.

• Question 320:

  An application is not performing well and will occasionally shut down with no error provided.

  Which of the following Task Manager tabs should be used to troubleshoot the application while it is active?

  A. Users
  B. Services
  C. Performance
  D. Startup
  C. Performance

  ---

  Explanation

  When troubleshooting an application that is not performing well and occasionally shuts down with no error, the "Performance" tab in Task Manager is the most appropriate tool to use. This tab provides real-time data on CPU, memory, disk,

  and network usage, which can help identify resource bottlenecks or spikes that could be causing the application to malfunction. Monitoring these metrics while the application is running can offer insights into whether the issue is related to

  system resources. Users tab shows which users are currently logged into the system and their resource usage but does not provide detailed performance metrics for troubleshooting application issues. Services tab shows the status of

  background services but does not provide direct information about the application's performance.

  Startup tab manages which applications start with Windows and their impact on startup time but is not useful for monitoring active application performance.
