Which of the following steps should a technician take next? (Select two).
- A . Isolate the computer from the network
- B . Enable the firewall service.
- C . Update the endpoint protection software
- D . Use System Restore to undo changes.
- E . Delete the browser cookies
- F . Run sfc /scannow.
A

Following a recent power outage, several computers have been receiving errors when booting. The technician suspects file corruption has occurred.
Which of the following steps should the technician try FIRST to correct the issue?
- A . Rebuild the Windows profiles.
- B . Restore the computers from backup.
- C . Reimage the computers.
- D . Run the System File Checker.
D
Explanation:
The technician should run the System File Checker (SFC) first to correct file corruption errors on computers after a power outage. SFC is a command-line utility that scans for and repairs corrupted system files. It can be run from the command prompt or from the Windows Recovery Environment. Rebuilding the Windows profiles, restoring the computers from backup, and reimaging the computers are more drastic measures that should be taken only if SFC fails to correct the issue1
A technician is troubleshooting a Windows 10 PC that is unable to start the GUI. A new SSD and a new copy of Windows were recently installed on the PC.
Which of the following is the most appropriate command to use to fix the issue?
- A . msconfig
- B . chkdsk
- C . sfc
- D . diskpart
- E . mstsc
C
Explanation:
The sfc command is a tool for scanning and repairing system files that are corrupted or missing on Windows operating systems12. System files are essential files that are required for the proper functioning of the operating system, such as the GUI, drivers, services, and applications. If system files are damaged or deleted, the operating system may fail to start or run properly, causing errors, crashes, or blue screens.
The sfc command can be used to fix the issue of the PC that is unable to start the GUI, assuming that the problem is caused by corrupted or missing system files. The sfc command can be run from the command prompt, which can be accessed by booting the PC from the installation media, choosing the repair option, and selecting the command prompt option3. The sfc command can be used with different switches, such as /scannow, /verifyonly, /scanfile, or /offbootdir, depending on the situation and the desired action4. The most common switch is /scannow, which scans all the system files and repairs any problems that are found5. The syntax of the sfc command with the /scannow switch is: sfc /scannow
The sfc command will then scan and repair the system files, and display the results on the screen. If the sfc command is able to fix the system files, the PC should be able to start the GUI normally after rebooting. If the sfc command is unable to fix the system files, the PC may need further troubleshooting or a clean installation of Windows.

- A . PIN code
- B . OS updates
- C . Antivirus software
- D . BYOD policy
A
Explanation:
A PIN code is a numeric password that protects a mobile device against unwanted access when it is left unattended. It requires the user to enter the correct code before unlocking the device. OS updates, antivirus software and BYOD policy are other security measures for mobile devices, but they do not prevent unauthorized access when the device is left unattended.

After a recent mobile OS upgrade to a smartphone, a user attempts to access their corporate email, but the application does not open. A technician restarts the smartphone, but the issue persists.
Which of the following is the most likely way to resolve the issue?
- A . Updating the failed software
- B . Registering the smartphone with an MDM solution
- C . Installing a third-party client
- D . Clearing the cache partition
A
Explanation:
Comprehensive and Detailed In-Depth
When a mobile OS is updated, some applications may become incompatible or corrupted due to changes in system files. The best solution is to update the failed software, as the app developer may have released a patch to resolve compatibility issues.
B. Registering the smartphone with an MDM solution C Incorrect. MDM (Mobile Device Management) helps with security policies but does not fix application compatibility issues.
C. Installing a third-party client C Incorrect. Using a different app may work but does not resolve the root cause of the issue.
D. Clearing the cache partition C While clearing the cache can help with performance, it is unlikely to resolve an application not opening due to an OS update.
