Question 1
A user installed an app from a website instead of the official app store. Which security concern does this raise most?
- The app may be malicious or tampered
- The app cannot use the internet
- The app will always run faster than store apps
- The app cannot access storage
Show the answer
A. The app may be malicious or tampered — Apps from unofficial sources bypass store review and may contain malware.
Question 2
A domain user waits several minutes at 'Preparing Windows' each sign-in. The user's roaming profile is 30 GB. What would help most?
- Disable the user's account lockout policy at sign-in
- Turn off the Windows firewall
- Increase the screen saver timeout
- Use folder redirection to shrink the roaming profile
Show the answer
D. Use folder redirection to shrink the roaming profile — Large roaming profiles are copied at each sign-in; redirecting folders to the server reduces load time.
Question 3
A browser that used to be fast is now very slow and the CPU spikes when it is open. What is a likely cause?
- A dead CMOS battery
- An NTFS permission issue on the profile folder
- A malicious or resource-heavy extension
- A wrong subnet mask
Show the answer
C. A malicious or resource-heavy extension — Degraded browser performance often comes from extensions, including cryptomining scripts; test with extensions disabled.
Question 4
A technician needs to start Windows with only basic drivers and services to troubleshoot a problem. Which mode does this?
- Safe Mode
- Fast startup
- Airplane mode
- Hibernate
Show the answer
A. Safe Mode — Safe Mode loads a minimal set of drivers and services.
Question 5
A user's Windows profile appears corrupted: a temporary profile loads at each sign-in. What is a common fix?
- Rebuild the search index and reinstall printers
- Reinstall all printer drivers
- Disable the user's account
- Create a new profile and copy the user's data
Show the answer
D. Create a new profile and copy the user's data — Corrupted profiles are commonly fixed by creating a fresh profile and migrating data.
