The correct answer is C. net use, which is the Windows command-line utility used to display, create, and remove mapped network drives and SMB (Server Message Block) connections. When working remotely through command-line interfaces, technicians often rely on net use to quickly verify which network shares are currently connected.
The Quentin Docter - CompTIA A+ Complete Study Guide explains that SMB is the protocol Windows uses for file and printer sharing, and mapped drives are maintained through SMB sessions. The net use command lists all active connections, including the drive letter, remote UNC path, and connection status.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide highlights that net use is especially valuable for remote troubleshooting because it does not require a graphical interface. This makes it ideal when administering multiple systems via command prompt or remote shell.
The Mike Meyers / Mark Soper Lab Manual clarifies that systeminfo displays OS and hardware details, hostname only shows the system name, and nslookup is used for DNS queries. None of those commands provide information about mapped SMB shares.
Since the task is to verify existing SMB mappings, net use is the only command that directly fulfills this requirement, making C the correct answer.

BSOD after driver installation suggests a compatibility issue.Safe Mode allows rollback of driversthat may be causing the crash.
FromTravis Everett - CompTIA A+ All-in-One Exam Guide:
"If a BSOD occurs after a driver update, boot into Safe Mode and roll back to the previous driver version to restore system stability."

The correct answer is D. Connect a wrist strap to a metal frame, because this action directly prevents electrostatic discharge (ESD), which is one of the most common causes of accidental hardware damage during device disassembly. Even when a device is powered off, static electricity stored in the technician's body can discharge into sensitive components such as RAM, CPUs, and system boards.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, the most effective way to prevent ESD is to equalize electrical potential between the technician and the device. An ESD wrist strap, when connected to a grounded metal surface such as a computer chassis, safely dissipates static electricity before it can damage components.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that while antistatic mats and bags are useful, they are secondary controls. The wrist strap provides continuous grounding throughout the repair process, whereas mats and bags only protect components when they are placed on or inside them.
The Mike Meyers / Mark Soper Lab Manual reinforces that working on plastic surfaces does not guarantee grounding, and placing components in antistatic bags is something done after removal, not immediately after powering down.
Therefore, once the device is turned off, the next and most important step is to connect a wrist strap to a metal frame, making D the correct answer.

An Acceptable Use Policy (AUP) outlines the rules and guidelines for employees or users regarding the appropriate use of company systems, resources, and internet access. It defines permitted and prohibited activities, helping to mitigate security risks and establish clear behavioral expectations.
B: MNDA (Mutual Non-Disclosure Agreement) deals with confidentiality, not usage guidelines.
C: DRM (Digital Rights Management) controls access to copyrighted content.
D: EULA (End User License Agreement) pertains to software licensing, not internal policies.

The correct answer is D. Folder redirection, because folder redirection allows specific user folders-such as Documents, Desktop, and Downloads-to be stored on a network share rather than the local computer. This ensures centralized storage, easier backups, and improved data security.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, folder redirection is commonly used in domain environments to store user data on file servers. This prevents data loss if a workstation fails and allows users to access their files from multiple systems.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that folder redirection works seamlessly with roaming profiles and Group Policy, ensuring that users do not need to manually save files to network drives.
The Mike Meyers / Mark Soper Lab Manual clarifies that file attributes only affect file behavior, UAC controls privilege elevation, and security groups control access permissions-but none of these determine where user folders are stored.
Because the requirement is to store documents on a network location instead of locally, configuring folder redirection is the correct and intended solution, making D the correct answer.
