Question 21
A user connects their laptop to a projector in a conference room. Once connected, the userreports the screen is smaller at the bottom than at the top. The user tries restarting the laptop and then disconnecting and reconnecting the cable to the projector. Which of the following should a technician do to resolve the issue?
Replace the HDMI cable.
Power cycle the projector.
Adjust the keystone
Increase the resolution.
Comprehensive and Detailed Explanation From Exact Extract:
A distorted image where the screen is not symmetrical (wider at the top or bottom) is typically due to keystone distortion. Adjusting the projector's keystone settings corrects this trapezoidal effect caused by an angled projection.

Question 22
A user is having issues when charging a device with a Lightning cable. The cable is not recognized when it is plugged into the device. This issue is usually resolved by flipping the cable over. This issue does not occur with other devices of the same type. Which of the following would most likely cause the issue?
The device needs to be restarted.
The battery may be swelling and needs inspection.
The cable is failing and needs to be replaced
The charging port is dirty or damaged
Comprehensive and Detailed Explanation From Exact Extract:
When a Lightning cable works only when flipped a certain way or doesn't function consistently, it is typically due to debris or damage in the charging port. Cleaning the port or inspecting it for wear resolves the issue.

Question 23
A customer is able to print most documents with their USB inkjet printer, but the system is unresponsive when printing a certain report from a custom application. Nothing will print until the computer is restarted and the printer is power cycled. A technician remotes into the PC and confirms that the spooler stops working when this report is sent. After cleaning the spooler and reinstalling the drivers from the manufacturer's website, the issue persists. No other sites using the application report similar issues. Which of the following is most likely causing the issue?
The manufacturer is curating content before it reaches the device to preserve ink.
The application has a bug that the developer needs to address.
The system is using the PostScript language instead of the PCL.
Personal preferences have changed and documents with graphics are now online-only
Comprehensive and Detailed Explanation From Exact Extract:
If a print spooler crashes specifically with one application and no issue occurs on other systems, the most likely root cause is a bug within that specific application. Restarting the spooler and reinstalling drivers resolves system-wide or hardware-related issues---not app-specific failures. This indicates the application may be sending malformed print data.

Question 24
A technician is troubleshooting a desktop PC that is plugged into a UPS. The PC loses the system date/time after every power outage. Which of the following should the technician do to resolve the issue? (Select two).
Run a BIOS update.
Swap out the RAM.
Disable NTP in the OS.
Repair the backup power source.
Replace the CMOS battery
Install a surge protector.
Comprehensive and Detailed Explanation From Exact Extract:
The system date/time is maintained by the CMOS battery when the PC is powered off. If this battery fails, time resets will occur. Additionally, since the system is connected to a UPS, ensuring the UPS is functioning correctly (i.e., the backup power source) is essential.
Reference: 'CompTIA A+ Complete Study Guide' by Quentin Docter -- Chapter 1, page 40.
Question 25
Which of the following is the best to use when testing a file for potential malware?
Multitenancy
Test development
Cross-platform virtualization
Sandbox
Comprehensive and Detailed Explanation From Exact Extract:
A sandbox is a secure, isolated environment used to test potentially harmful software or code. It prevents the software from affecting the main system, allowing safe malware testing. Thismethod is standard in cybersecurity best practices.

Question 26
A systems administrator deploys BitLocker to all devices. However, one of the desktop PCs is not able to encrypt the boot drive. Which of the following should the administrator check?
TPM
CPU
RAM
HDD
Comprehensive and Detailed Explanation From Exact Extract:
BitLocker Drive Encryption in Windows requires aTrusted Platform Module (TPM)to encrypt the boot drive securely. The TPM is a dedicated microcontroller designed to secure hardware through integrated cryptographic keys. It validates system integrity during boot and securely stores the encryption keys. If BitLocker cannot find a TPM or it is disabled in BIOS/UEFI, drive encryption cannot proceed.
BitLocker can function without TPM using a USB startup key, but this compromises some security and is not recommended for managed enterprise environments.

Question 27
Users working with large files back up the files to external hard drives. One user's files take longer to back up than other users' files. The user has tried backing up the files to other users' drives with the same results. Which of the following steps should the technician take first to correct this issue?
Replace the hard drive's USB cable.
Defragment the user's external hard drive.
Update the storage drivers on the user's system.
Instruct the user to compress the files.
If a hard drive is heavily fragmented, file read/write operations can take significantly longer, causing slow backup speeds. Defragmenting the drive organizes the data for more efficient access.
Why Not A (Replace the hard drive's USB cable): A faulty cable would typically cause disconnections or errors, not just slower speeds.
Why Not C (Update the storage drivers): This might help if the issue is with system drivers, but the described symptoms point to a fragmentation issue.
Why Not D (Compress the files): Compression reduces file size but does not address the root cause of the slow backups.
