A corruptedMaster Boot Record (MBR)is a common issue after disk manipulation. Booting from installation media and using tools like bootrec to repair the MBR can resolve the problem.

Travis Everett – All-in-One Exam Guideexplains:

“A damaged MBR may result in the OS not loading. Booting from recovery or installation media and selecting startup repair or running bootrec commands can restore functionality.”

The correct answer is C. Disconnect the power , because safety is the first priority when working inside a computer case. Before opening the system, all power sources must be removed to prevent electrical shock and hardware damage.

According to the Quentin Docter – CompTIA A+ Complete Study Guide , technicians should always shut down the system and disconnect the power cable before opening a computer. Even powered-off systems can still carry electrical current if they remain plugged in.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide explains that unexpected noises are often caused by fans, loose cables, or failing hard drives. Opening the case while the system is powered can cause injury or damage sensitive components.

The Mike Meyers / Mark Soper Lab Manual reinforces the standard safety sequence: power off the system, unplug it, discharge residual power, and then apply grounding measures before touching internal components.

Because disconnecting power eliminates electrical hazards and protects both the technician and the equipment, C is the correct answer.

Virtualizationallows the legacy OS to be run in a virtual machine (VM) on top of the newer OS. This method provides backward compatibility without requiring outdated operating systems on physical hardware.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Using virtualization is a preferred method when legacy applications are needed after migrating to newer operating systems. It allows legacy environments to exist securely within a modern OS framework.”

To allow Remote Desktop Protocol (RDP) access, the firewall must be configured to allow inbound connections on TCP port 3389. If the Windows Firewall blocks RDP, users will not be able to connect remotely even if the feature is enabled in system settings.

B. Computer Management allows configuration of services and local users, but not network access.

C. User Accounts is for account setup and control, but enabling remote access requires firewall configuration.

D. Ease of Access is unrelated to remote connectivity—it’s for accessibility features.
