220-1202 Practice Test 10 — 10 Questions

Question 1

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)?

Choose an answer to begin — your selection is scored in the full session.

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 2

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

bootrec /rebuildbcd. The bootrec tool is specifically designed to repair BCD and boot sector issues. Running bootrec /rebuildbcd scans for Windows installations and rebuilds the BCD store.

Answer

chkdsk /f

Answer

sfc /scannow

Answer

diskpart

Question 3

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 4

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

Question 5

A user reports that their browser frequently redirects to a different search engine, and a new toolbar has appeared. After checking the browser settings, you find the homepage has been changed and there are unknown extensions enabled. What is the most likely cause of this issue?

Accepted Answer

A browser hijacker installed via a malicious extension. This scenario describes classic symptoms of a browser hijacker, a type of malware that modifies browser settings without user consent. The correct answer is to remove the malicious extensions and reset the browser settings. This reinforces the importance of managing browser extensions and understanding common malware behaviors.

Answer

A corrupted browser cache

Answer

An outdated browser version

Answer

A misconfigured proxy server

Question 6

A user reports that their computer is displaying a message claiming their files are encrypted and they must pay 0.5 Bitcoin to a specific address to regain access. The user cannot open any documents or photos. What is the first step the technician should take to respond to this incident?

Accepted Answer

Disconnect the computer from the network.. The first step in a ransomware incident is to isolate the infected system from the network to prevent the malware from spreading to other devices. Attempting to decrypt without tools or paying the ransom are not recommended initial actions.

Answer

Pay the ransom to recover the files immediately.

Answer

Run a full antivirus scan to remove the malware.

Answer

Reboot the computer into Safe Mode.

Question 7

A company's security policy requires that all laptops returned by employees be sanitized before redeployment. A technician uses a degausser on a laptop's SSD. What is the likely outcome?

Accepted Answer

The SSD is physically destroyed and unusable.. A degausser generates a powerful magnetic field to erase data from magnetic media. SSDs (Solid State Drives) store data in NAND flash memory cells, which are not magnetic. The intense magnetic field from a degausser induces high currents in the SSD's internal circuitry, physically destroying the controller and memory chips, rendering the drive completely unusable.

Answer

The SSD is completely erased and ready for reuse.

Answer

The SSD is unaffected and still contains data.

Answer

The laptop's BIOS is reset.

Question 8

A user reports that their Windows 10 laptop will not boot and displays the error 'Bootmgr is missing'. They have a valid Windows installation USB. Which steps should you take to repair the boot manager?

Accepted Answer

Boot from the USB, go to Troubleshoot > Advanced Options > Command Prompt, and run 'bootrec /rebuildbcd' and 'bootrec /fixmbr'.. The 'Bootmgr is missing' error indicates that the Boot Manager (bootmgr) is either corrupted or missing, or the BCD (Boot Configuration Data) store is damaged. Booting from a Windows installation USB and using the Command Prompt via Troubleshoot > Advanced Options allows you to run 'bootrec /rebuildbcd' to scan for Windows installations and rebuild the BCD store, and 'bootrec /fixmbr' to repair the Master Boot Record (MBR) on the system partition. This directly addresses the boot manager issue by restoring the boot configuration and ensuring the MBR points to the correct boot sector.

Answer

Boot from the USB and select 'Repair your computer' > 'Startup Repair'.

Answer

Boot from the USB and run 'sfc /scannow' from the Command Prompt.

Answer

Boot from the USB and perform a system restore to a previous point.

Question 9

A small business wants to ensure that only authorized personnel can access the server room. The budget is limited, and they need a simple, cost-effective solution. Which logical security control should they implement first?

Accepted Answer

Require a smart card or key fob to unlock the door.. A smart card or key fob provides a simple, cost-effective logical access control for the server room door. It authenticates users via a physical token and a PIN or proximity reader, which is far cheaper than biometric systems and more reliable than a password policy that doesn't control physical entry. This directly restricts physical access to authorized personnel without ongoing costs like a security guard.

Answer

Install a biometric fingerprint scanner on the door.

Answer

Implement a strong password policy for all user accounts.

Answer

Hire a security guard to check IDs at the entrance.

Question 10

A security audit reveals that a company's remote access solution uses a VPN with pre-shared keys (PSK) for authentication. The auditor recommends upgrading to certificate-based authentication. Which of the following is the primary security advantage of certificate-based authentication over PSK?

Accepted Answer

Certificates provide mutual authentication and are unique per device, reducing the risk of a single compromised key affecting all users.. Certificate-based authentication provides mutual authentication, meaning both the VPN client and server verify each other's identity using digital certificates issued by a trusted Certificate Authority (CA). Unlike PSK, which is a shared secret that can be leaked and reused across all devices, each certificate is unique per device, so compromise of one certificate does not expose the entire VPN infrastructure. This significantly reduces the blast radius of a security breach and aligns with the principle of least privilege.

Answer

Certificates are easier to configure and manage than PSK.

Answer

Certificates eliminate the need for a VPN server.

Answer

Certificates are faster than PSK for establishing VPN connections.
