Windows Hello provides biometric authentication options, including facial recognition, fingerprint scanning, and iris scanning, aligning with the company's requirement for biometric identification.
Why Not A (BitLocker): BitLocker is for encrypting data, not biometric authentication.
Why Not C (Defender): Windows Defender provides antivirus and security features, not biometric functionality.
Why Not D (Trusted Platform Module): TPM is a hardware feature for secure cryptographic operations, not biometric authentication.

The tool that the technician should use to see all drives is Diskmgmt. Diskmgmt is a Windows utility that allows you to manage disk drives and partitions on your computer. It can be used to view all drives, including USB drives, that are connected to the computer12.

The user should check the display settings on the computer and set them to extend/duplicate. This will allow the computer to send the video signal to both the laptop screen and the projector. If the display settings are set to only show on one screen, then the projector may not detect any source. According to the CompTIA Core1 objectives, one of the common display issues is no image on screen. A troubleshooting guide for projectors also suggests checking the display settings as a possible solution for no source found error.

If an application was previously running in a virtualized environment and is not launching after being installed directly on the base operating system, it's possible that the technician did not account for dependencies or configurations specific to the virtualized environment that are not present or are incompatible with the base operating system. This mismatch can prevent the application from launching properly.

Display burn-in occurs when a static image is left on a screen for a long time, causing the pixels to wear out unevenly and retain a ghost image even when new content is displayed. This issue can result in double images, where the "burned-in" stationary image persists alongside new, live content. This problem is more common in older displays or those used for static signage. Replacing the display cable or adjusting color settings would not address the underlying cause of uneven pixel wear, and burned-out bulbs would likely result in a loss of image clarity or brightness, not double images.
