Sample CompTIA A+ Core 2 2024 questions

1. A Windows 11 workstation reports that System File Checker found corrupted files but could not repair some of them. Which command should a technician run next to repair the Windows component store before rerunning SFC?
  1. chkdsk C: /f
  2. DISM /Online /Cleanup-Image /RestoreHealth
  3. defrag C: /O
  4. format C: /FS:NTFS

Answer: B. DISM /Online /Cleanup-Image /RestoreHealth

DISM with RestoreHealth repairs the online Windows image/component store that SFC can use as a source for replacement files. CHKDSK checks the file system, while defragmentation and formatting do not repair the component store.

2. A macOS user reports that one application is consuming excessive CPU. The technician needs to identify the process and, if necessary, stop it. Which built-in utility is most appropriate?
  1. Disk Utility
  2. Keychain Access
  3. Activity Monitor
  4. System Information

Answer: C. Activity Monitor

Activity Monitor displays running processes and resource utilization and allows a process to be quit. Disk Utility manages storage, Keychain Access manages credentials, and System Information reports hardware and software details.

3. On a Linux system, a file should have read/write permission for its owner, read-only permission for its group, and no permissions for other users. Which chmod numeric value sets these permissions?
  1. 640
  2. 644
  3. 660
  4. 740

Answer: A. 640

The owner permissions rw- equal 6, the group permission r-- equals 4, and no permissions for others equals 0, giving 640. A value of 644 would also grant read permission to other users.

4. A Windows 11 user needs a shared folder from a file server to appear as a drive letter after every sign-in. Which action best meets this requirement?
  1. Add the share to the Recycle Bin
  2. Create a local user account with the same name as the server
  3. Pin the share's web address to Start
  4. Map the network drive and select Reconnect at sign-in

Answer: D. Map the network drive and select Reconnect at sign-in

Mapping the share assigns it a drive letter, and Reconnect at sign-in makes Windows restore the mapping for later sessions. Pinning a location does not create a persistent mapped drive.

5. An employee receives an unexpected push notification asking to approve a sign-in, even though the employee is not logging in. What should the employee do immediately?
  1. Approve it and change the password next week
  2. Disable multifactor authentication permanently
  3. Deny the request and report the unexpected prompt through the organization's security process
  4. Send the account password to the help desk by email

Answer: C. Deny the request and report the unexpected prompt through the organization's security process

Denying an unrequested MFA prompt prevents the user from approving a likely unauthorized attempt, and reporting it allows the organization to investigate. Approving it grants access, while disabling MFA or emailing a password creates additional risk.
