CompTIA 220-1102 Online Questions & Answers

• Question 211:

  A technician thinks that a computer on the network has been infected with malware. The technician attempts several times to use a malware removal tool, but the issue persists.

  Which of the following should the technician do next?

  A. Restore the computer from the last known-good backup
  B. Reboot the computer into safe mode
  C. Purchase a new endpoint protection tool
  D. Use system recovery to prevent further infection
  B. Reboot the computer into safe mode

  ---

  Explanation

  Rebooting the computer into safe mode (Option B) limits the processes and services that run, which can help in isolating and removing persistent malware that might be hiding in normal mode. Safe mode provides a cleaner environment to

  troubleshoot and remove malware. Restoring from a backup (Option A) may work but should be considered after attempts to clean the infection. Purchasing a new endpoint protection tool (Option C) is unnecessary at this stage since existing

  tools can be run in safe mode. Using system recovery (Option D) could potentially remove the infection, but it's a more drastic step that may not be necessary yet.

• Question 212:

  An employee lost a smartphone and reported the loss to the help desk. The employee is concerned about the possibility of a breach of private data.

  Which of the following is the best way for a technician to protect the data on the phone?

  A. Remote lockBRemote wipe
  B. Remote access
  C. Remote encrypt
  B. Remote access

  ---

  Explanation

  When a smartphone is lost, especially one that might contain sensitive or private data, the primary concern is to ensure that any data on the device cannot be accessed by unauthorized persons. Among the options provided:

  Remote lock: This option will lock the device remotely, preventing access. However, it does not remove the data and might not be effective if the device is powered off or reset. Remote wipe: This is the best option as it allows the technician to

  erase all data from the device remotely, ensuring that sensitive information is not accessible to anyone who finds or steals the device. Remote access: This option would allow a technician to access the device remotely, but it would not

  directly prevent unauthorized access or data breaches.

  Remote encrypt: Encrypting the device remotely might not be possible if the device is not accessible or turned on, and it does not remove existing data which could be at risk.

• Question 213:

  Which of the following is the most secure screen lock?

  A. Face
  B. Swipe
  C. Password
  D. Fingerprint
  C. Password

  ---

  Explanation

  Passwords provide the highest level of security because they cannot be bypassed using biometric spoofing techniques.

  Option A: Face, Can be fooled with 2D images (on some devices).

  Option B: Swipe, Very weak security.

  Option D: Fingerprint, More secure than face/swipe but can still be faked.

• Question 214:

  A user is having issues with document-processing software on a Windows workstation. Other users that log in to the same device do not have the same issue. Which of the following should a technician do to remediate the issue?

  A. Roll back the updates.
  B. Increase the page file.
  C. Update the drivers.
  D. Rebuild the profile.
  D. Rebuild the profile.

  ---

  Explanation

  The issue is specific to the user's profile, so the technician should rebuild the profile. Rebuilding the profile will create a new profile and transfer the user's data to the new profile

• Question 215:

  A user is unable to access the internet but can still print to network printers. Other users are not experiencing this issue. Which of the following steps should the technician take first to diagnose the issue?

  A. Validate physical connectivity.
  B. Reboot the router.
  C. Disable IPv6.
  D. Check the DNS settings.
  A. Validate physical connectivity.

  ---

  Explanation

  When a single user is experiencing network issues while others are unaffected, the first step should always be to check the physical connectivity. This includes verifying that the Ethernet cable is plugged in properly, the NIC is enabled, and

  the link lights are active.

  Option B (Reboot the router): Affects all users and is not necessary since others are not experiencing the issue.

  Option C (Disable IPv6): Unlikely to resolve the problem unless you're troubleshooting a specific IPv6-related issue.

  Option D (Check the DNS settings): A valid step if internet access is limited to name resolution problems, but start with physical connectivity first.

• Question 216:

  A user's Windows 10 workstation with an HDD is running really slowly. The user has opened, closed, and saved many large files over the past week. Which of the following tools should a technician use to remediate the issue?

  A. Disk Defragment
  B. Registry Editor
  C. System Information
  D. Disk Cleanup
  A. Disk Defragment

  ---

  Explanation

  Over time, especially with frequent opening, modification, and saving of large files, a hard disk drive (HDD) can become fragmented. Fragmentation occurs when pieces of individual files are scattered across the disk, leading to longer read and write times, which can significantly slow down the computer. Disk defragmentation reorganizes these fragmented files, placing the pieces closer together on the drive, which improves access time and overall system performance. Disk Defragment: Using the Disk Defragment tool on a Windows 10 system with an HDD will help in reorganizing the data more efficiently, thus potentially remedying the slow performance issue. The Registry Editor (B) is a tool that allows for the viewing and editing of the Windows registry and is generally not used for performance improvement but rather for system settings and configuration adjustments. System Information (C) provides a detailed look at the computer's hardware and system details but does not offer tools for performance improvement. Disk Cleanup (D) can help free up space on the hard drive by removing temporary files and system files that are no longer needed, which can indirectly improve performance but is not the primary tool for addressing fragmentation.

• Question 217:

  A technician is setting up a backup method on a workstation that only requires two sets of tapes to restore. Which of the following would BEST accomplish this task?

  A. Differential backup
  B. Off-site backup
  C. Incremental backup
  D. Full backup
  A. Differential backup

  ---

  Explanation

  Differential should be since 2 backups are needed to restore thus (Differential before incremental)

• Question 218:

  Which of the following protocols supports fast roaming between networks?

  A. WEP
  B. WPA
  C. WPA2
  D. LEAP
  E. PEAP
  C. WPA2

  ---

  Explanation

  WPA2 is the only protocol among the options that supports fast roaming between networks. Fast roaming, also known as IEEE 802.11r or Fast BSS Transition (FT), enables a client device to roam quickly in environments implementing WPA2

  Enterprise security, by ensuring that the client device does not need to re-authenticate to the RADIUS server every time it roams from one access point to another1. WEP, WPA, LEAP, and PEAP do not support fast roaming and require the

  client device to perform the full authentication process every time it roams, which can cause delays and interruptions in the network service.

• Question 219:

  A wireless network is set up, but it is experiencing some interference from other nearby SSIDs. Which of the following can BEST resolve the interference?

  A. Changing channels
  B. Modifying the wireless security
  C. Disabling the SSIO broadcast
  D. Changing the access point name
  A. Changing channels

  ---

  Explanation

  Changing channels can best resolve interference from other nearby SSIDs. Wireless networks operate on different channels, and changing the channel can help to avoid interference from other nearby networks.

• Question 220:

  A user contacts the help desk to request assistance with a program feature. The user is in a different building but on the same network as the help desk technician. Which of the following should the technician use to assist the user?

  A. AAA
  B. SSH
  C. RDP
  D. VPN
  C. RDP
