A projector has been shutting down after 30 minutes of use, and it has a strange smell The technician confirms the power source is not the cause of the issue Which of the following steps should the technician take next to resolve this issue?
Correct Answer:
C
Reasoning: Projectors have air filters that prevent dust from entering the internal components. A clogged filter can cause the projector to overheat, resulting in shutdowns and even strange smells due to overheating components. Cleaning the filter is a standard
troubleshooting step when projectors exhibit overheating symptoms.
Why the Other Options Are Incorrect:
* A. Replace the bulb:
While a failing bulb may eventually cause issues, it would not typically result in a strange smell or repeated shutdowns after a fixed period. Bulb issues usually manifest as dim or flickering images.
* B. Check the projector configuration:
Configuration settings, such as resolution or input options, would not cause overheating or shutdowns. This option does not address the described symptoms.
* D. Adjust the gamma settings:
Gamma settings affect display brightness and contrast but have no impact on overheating or strange smells.
Practical Example:
Dust accumulation in projectors is a common issue, especially in environments with poor air circulation. A clogged filter causes restricted airflow, leading to overheating and automatic shutdowns to protect internal components. Cleaning the filter typically resolves this issue.

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?
Correct Answer:
A
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.

A user is experiencing multiple issues with an in-place upgrade of a laptop's operating system. The built-in camera is unresponsive, and the user is unable to pair the device with any Bluetooth accessories. Which of the following ate most likely causing three issues? (Select two).
Correct Answer:
CE
Outdated drivers: Device functionality issues after an OS upgrade are often caused by incompatible or outdated drivers.
Disabled settings: Some features may be disabled during the upgrade process, requiring re-enablement.
Why Not A (Incorrect configuration): This is unlikely given the issues arose only after the upgrade.
Why Not B (OS and device incompatibility): Upgrades check for compatibility before installation.
Why Not D (Full storage): Storage issues typically prevent installation, not device functionality.
Why Not F (Corrupted registry entries): While possible, this is less common than the selected answers.
CompTIA A+ Exam Reference: Core 1 (220-1201), Section 3.5, troubleshooting OS upgrades.

A technician is troubleshooting stylus issues on identical, company-provided tablets. Users can purchase their own accessories. Some users have no issues, but others report that their styluses charge intermittently and die frequently. Which of the following is the most likely cause of this issue?
Correct Answer:
A
Comprehensive and Detailed In-Depth Explanation:
The most likely cause isthird-party or ill-fitting casesobstructing the contact between the stylus and the tablet charging mechanism. Some cases may not be designed with stylus charging in mind, particularly if users are purchasing their own accessories.
✑ Option B:A software update might fix OS-related issues, but would not typically
affect physical charging.
✑ Option C:If some devices had defects, the issue would likely be consistent, not isolated to some users.
✑ Option D:Firmware issues could be a factor but are less likely than physical obstructions when users are using different accessories.

A technician needs to select PC components with a minimal number of visible internal cables. Which of the following should the technician use?
Correct Answer:
C
Comprehensive and Detailed In-Depth Explanation:
Amodular power supplyallows a technician toconnect only the power cables that are needed, reducing clutter and improving airflow. This is ideal when aiming for a clean build withminimal visible internal cables.
✑ Option A (SATA drive connections):Still require both power and data cables,
adding to cable count.
✑ Option B (Liquid cooling):May reduce some bulk from large air coolers, but adds tubing and still needs cabling.
✑ Option D (Wireless NIC):Adds wireless capability but has no relation to internal cabling cleanliness.
