220-1202 Practice Test 4 — 25 Questions

Question 1

A user complains that their Android phone's battery drains extremely fast after a recent OS update. They have already tried restarting the device. What is the most likely cause and solution?

Accepted Answer

The device is performing background indexing; wait a day or two.. After a major OS update, Android devices often perform background indexing of files, media, and app data to optimize search and performance. This process is CPU- and I/O-intensive, causing increased battery drain for 24–48 hours. The correct solution is to wait a day or two for indexing to complete, as restarting alone does not stop this background task.

Answer

The update installed a malware app; perform a factory reset.

Answer

The update reset battery optimization settings; re-enable them.

Answer

The battery is failing due to the update; replace the battery.

Question 2

A technician is called to a user's desk for a 'printer issue.' Upon arrival, the user is on a phone call and waves dismissively at the technician. The technician waits for two minutes, but the user continues their call. What should the technician do?

Accepted Answer

Leave a note on the desk saying you were there and will return later, then check back in 15 minutes.. It demonstrates professional respect for the user's current activity while ensuring the issue is addressed. Leaving a note and returning in 15 minutes maintains a service-level commitment without disrupting the user's call, aligning with CompTIA's best practices for customer communication and time management in a support scenario.

Answer

Stand silently until the user finishes the call, even if it takes a long time.

Answer

Interrupt the call to say you'll come back later.

Answer

Close the ticket as 'user not available' and move on to the next task.

Question 3

A technician is troubleshooting a Windows 10 computer that exhibits strange behavior: system files are missing, and the computer fails to boot normally. A boot-time virus scan detects a virus that infected the Master Boot Record (MBR). Which tool should the technician use to repair the MBR?

Accepted Answer

Bootrec.exe /FixMbr. The Bootrec.exe /FixMbr command writes a new Master Boot Record (MBR) to the system partition, overwriting the infected boot code without affecting the existing partition table. This is the correct tool for repairing a virus-compromised MBR that prevents normal booting on Windows 10.

Answer

System Restore

Answer

SFC /Scannow

Answer

CHKDSK /F

Question 4

A technician is configuring a new Windows 10 workstation for a user who handles sensitive financial data. The company policy mandates that the screen lock after 5 minutes of inactivity and require a password on wake. Which settings should the technician configure?

Accepted Answer

Configure the screen saver to start after 5 minutes and check 'On resume, display logon screen.'. The screen saver settings in Windows include an option to 'On resume, display logon screen,' which locks the workstation after the screen saver activates. Setting the screen saver timeout to 5 minutes and enabling the logon screen requirement meets the policy.

Answer

Set the power plan to turn off the display after 5 minutes.

Answer

Enable the 'Require password on wakeup' setting in the power plan only.

Answer

Set the computer to sleep after 5 minutes and require a password on wake.

Question 5

An iOS user complains that their iPhone will not connect to a known Wi-Fi network, but other devices on the same network work fine. Which iOS-specific troubleshooting step should you perform first to resolve this issue without erasing any personal data?

Accepted Answer

Use the 'Reset Network Settings' option in Settings > General > Reset.. The correct step is to use the 'Reset Network Settings' option in iOS, which clears saved Wi-Fi networks, VPN configurations, and other network-related settings without affecting personal data like photos or contacts. This often resolves stubborn Wi-Fi connection issues. A full factory reset or iCloud restore would be excessive and data-destructive.

Answer

Reset All Settings from the General > Reset menu.

Answer

Erase All Content and Settings to start fresh.

Answer

Restore the iPhone from an iCloud backup.

Question 6

A user reports that their Android phone's screen is unresponsive to touch, but the buttons and notification LED still work. They have already performed a forced restart. What should the technician do NEXT?

Accepted Answer

Boot the phone into Safe Mode to check if the issue persists.. This scenario tests troubleshooting touchscreen issues. Since a forced restart didn't help, booting into Safe Mode can determine if a third-party app is causing the problem.

Answer

Replace the screen assembly.

Answer

Perform a factory reset from the recovery menu.

Answer

Update the phone's firmware using a computer.

Question 7

A technician is writing a batch script to automate the installation of a software package on multiple Windows workstations. The script needs to check if the software is already installed before attempting installation. Which scripting construct should the technician use?

Accepted Answer

An if statement. This tests knowledge of conditional logic in scripting. An 'if' statement allows the script to check a condition (e.g., existence of a registry key or file) and execute code only if the condition is true or false. Loops are for repetition, and variables store data, not control flow.

Answer

A for loop

Answer

A variable

Answer

A while loop

Question 8

A retail store wants to protect its point-of-sale (POS) terminals from unauthorized physical access during off-hours. The terminals are in an open area with no lockable cabinets. Which control should be prioritized?

Accepted Answer

Use tamper-evident seals on the terminal casings.. Tamper-evident seals provide a visible indicator if a device has been opened, deterring unauthorized physical access to internal components. This question tests understanding of physical security for unattended devices.

Answer

Install a privacy screen on each POS terminal.

Answer

Require a smart card to power on the terminal.

Answer

Enable a screensaver with a password.

Question 9

A user reports that their Windows 10 computer is infected with a virus that keeps reinstalling itself after removal. What should you do to remediate this persistent infection?

Accepted Answer

Boot from a rescue disc or USB and run an antivirus scan. A virus that reinstalls itself likely has a rootkit or persistent mechanism. Booting from trusted media and scanning the offline system ensures the malware cannot run, allowing complete removal.

Answer

Run a system restore to a previous restore point

Answer

Disable System Restore and then run an antivirus scan in normal mode

Answer

Reinstall Windows from the recovery partition

Question 10

After a security incident, a Windows 10 workstation is suspected of having malware that prevents the Task Manager and Command Prompt from opening. You need to run a system scan. Which tool can you use from the Windows Recovery Environment (WinRE) to perform an offline antivirus scan?

Accepted Answer

Microsoft Defender Offline Scan. Windows Defender Offline (now part of Microsoft Defender Antivirus) can be run from the Windows Recovery Environment to scan for malware without booting the infected OS. This bypasses malware that blocks security tools in the normal Windows environment. It is the appropriate tool for this scenario.

Answer

System File Checker (sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows)

Answer

Windows Memory Diagnostic

Answer

Diskpart

Question 11

A company requires that all remote access sessions be recorded for compliance purposes. The current VPN solution does not support session recording. Which of the following additional technologies can be integrated to capture and store remote desktop sessions?

Accepted Answer

Implement a Remote Desktop Gateway with session recording software. A Remote Desktop Gateway (RD Gateway) can be configured to broker and log RDP sessions, and when combined with a session recording solution, it can capture all activity. VPN alone does not provide session recording, and other methods like VNC or SSH typically lack built-in recording features.

Answer

Use SSH tunneling for all remote access

Answer

Configure the VPN to use PPTP instead of L2TP

Answer

Deploy a VNC server on each remote workstation

Question 12

A user complains that their Android phone's battery drains quickly after installing a new weather app. The phone is warm to the touch even when idle. What should you do to resolve this?

Accepted Answer

Check battery usage in Settings to see which app is consuming power.. Battery drain and overheating after app installation indicate a misbehaving app. The best first step is to check battery usage statistics to identify the culprit, then force stop or uninstall that app. This is a standard Android troubleshooting procedure.

Answer

Replace the battery immediately.

Answer

Perform a factory reset to remove all apps.

Answer

Update the phone's operating system to the latest version.

Question 13

A company is deploying new laptops to remote workers. They need to ensure that if a laptop is stolen, the data on it cannot be accessed. Which two physical security controls should be configured before shipment?

Accepted Answer

Full-disk encryption and a BIOS/UEFI password.. Full-disk encryption protects data at rest, and a BIOS/UEFI password prevents unauthorized booting or tampering with boot settings. This question tests the combination of controls needed for remote device security.

Answer

Cable lock and privacy filter.

Answer

Smart card reader and biometric scanner.

Answer

Asset tracking tag and a Kensington lock slot.

Question 14

A technician is configuring a new server room and needs to ensure that only authorized personnel can physically access it. The company wants a solution that does not require replacement of keys or cards if one is lost. Which access control method best meets this requirement?

Accepted Answer

Implement a biometric fingerprint reader. Biometric systems use unique physical traits (fingerprint, retina) that cannot be lost or easily duplicated. This eliminates the need to reissue credentials if a card or key is lost, though biometrics have their own management challenges.

Answer

Use a combination lock

Answer

Install a smart card system

Answer

Use a keypad with a PIN code

Question 15

A user reports that their cloud-synced files are not appearing on their laptop after a recent OS reinstall. The technician verifies that the cloud storage account is active and the internet connection works. Which of the following is the most likely reason for the missing files?

Accepted Answer

The local sync client is configured for selective sync and not downloading all folders. Cloud storage clients use a local cache to sync files. After an OS reinstall, the client must re-download files from the cloud, but if selective sync is enabled, only certain folders are synced. The user may need to adjust sync settings to restore all files. This tests understanding of cloud storage synchronization behavior.

Answer

The cloud storage provider has deleted the files due to inactivity

Answer

The user's account is not licensed for the cloud service

Answer

The laptop's hard drive is full

Question 16

A technician is troubleshooting a Windows 10 PC that fails to boot with a 'Bootmgr is missing' error. They need to repair the boot configuration. Which administrative tool should be used from the Windows Recovery Environment (WinRE)?

Accepted Answer

Command Prompt to run bootrec /rebuildbcd.. The Command Prompt in WinRE allows running bootrec.exe and bcdedit.exe to repair the boot configuration. System Restore and Startup Repair are also in WinRE but do not directly rebuild the BCD. The other options are not available in WinRE.

Answer

System Restore to revert to a previous restore point.

Answer

Device Manager to update the disk driver.

Answer

Local Security Policy to adjust boot options.

Question 17

A customer complains that their Windows 10 PC fails to boot and displays a 'Bootmgr is missing' error. You suspect the Boot Configuration Data (BCD) is corrupted. Which tool should you use to repair the BCD from the Windows Recovery Environment?

Accepted Answer

Question 18

A user reports that their iPad will not rotate the screen when they turn the device sideways. The rotation lock icon appears in the status bar. What is the most likely cause?

Accepted Answer

Rotation lock is enabled in Control Center or via the side switch.. The rotation lock icon indicates the feature is enabled. On an iPad, this can be controlled via the Control Center or a physical switch on the side. The technician should disable rotation lock before any other troubleshooting.

Answer

The accelerometer is faulty.

Answer

The app being used does not support rotation.

Answer

The device needs a software update to fix a rotation bug.

Question 19

A customer reports that their Windows 10 computer is running very slowly, and they see frequent pop-up ads even when no browser is open. They also notice a new toolbar in their browser that they did not install. What type of malware is most likely causing these symptoms?

Accepted Answer

Adware. Adware displays unwanted advertisements and often installs browser toolbars, slowing down the system. Unlike a virus or worm, adware does not self-replicate, and ransomware would demand payment rather than show ads.

Answer

Ransomware

Answer

Virus

Answer

Worm
