3-D rendering is a graphics-intensive workload, and minimum hardware checks for this type of software commonly fail due to GPU capability (including dedicated vs. integrated GPU support) and VRAM requirements. Quentin Docter explains that application “Display” requirements can include “a graphics processing unit (GPU). A specific GPU may be required if the application will process video or graphics.” He also notes that “VRAM requirements are typically related to applications that are graphic intensive, such as gaming,” which aligns strongly with 3-D rendering workloads.

Mike Meyers’ Lab Manual reinforces that “graphically demanding applications… state specific graphics requirements,” and that CompTIA focuses on “dedicated graphics cards versus integrated ones,” because integrated GPUs are often less capable for demanding graphics tasks. It also reminds that systems with integrated GPUs share RAM with graphics, which can matter when software checks VRAM.

Therefore, the first thing to verify is GPU requirements (B), not USB/NIC/PSU.

SSO issues are often related to cached session data, cookies, or browser artifacts. The fact that the user can access the company portal but not one specific SaaS tool suggests a session or token problem. Using a private/incognito browsing window allows a clean session to be initiated, which often resolves SSO conflicts.

A. Reenrolling MFA is not related unless access issues stem from failed multifactor authentication.

C. Bypassing SSO may not be possible depending on the SaaS tool and company policies.

D. Factory resetting a device is a last resort and unnecessary in this case.

Once the system is cleaned, the next priority is toeducate the useron safe practices to prevent recurrence.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Post-malware remediation should include user education to prevent reinfection and identify how the malware was introduced.”

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.

The su (substitute user) command is used in Linux to switch to another user account, most commonly to escalate privileges by switching to the root (administrator) account. It allows administrative tasks to be performed in a terminal session.

A. runas is a Windows command for executing a program under another user ' s context.

B. cmcl is not a valid Linux or administrative command.

C. net user is a Windows command for managing local user accounts.

These symptoms strongly indicatemalware infectionor a malicious app running in the background. The first action should be torun a malware scanto identify and remove malicious components.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“If a mobile device is overheating and the battery drains rapidly after installing an app, this could point to malware. Begin by scanning the device with a mobile anti-malware application.”

The wrist strap is an ESD (electrostatic discharge) prevention tool used to keep the technician and the computer at the same electrical potential so static electricity doesn’t discharge into sensitive components like RAM. Quentin Docter explains that with an antistatic (ESD) wrist strap, you “attach one end to an earth ground… or the computer case and wrap the other end around your wrist. This strap grounds your body and keeps it at a zero charge.” This directly matches option C.

Mike Meyers’ Lab Manual reinforces the same concept: “The secret to avoiding ESD is to keep you and the parts of the computer you touch at the same electrical potential, otherwise known as grounding yourself to the computing device. You can accomplish this by connecting yourself to the computer via… an ESD strap.” In practical terms, RAM and CPU chips are especially ESD-sensitive, so grounding prevents intermittent or catastrophic failures that might occur after installation. Therefore, the purpose of the wrist strap is to ground electrostatic charge.

When a system begins randomly crashing after a hardware change (installing a GPU) and the correct vendor driver update does not resolve it, the best next troubleshooting step is to collect evidence about what is failing. Windows records crash details, driver faults, and unexpected shutdowns in Event Viewer (System/Application logs) and related reliability tools. Quentin Docter specifically states that Event Viewer should be the first place you look when the solution is not evident because applications and the OS often create log entries that help verify operation and diagnose problems. These logs can reveal whether the crash is tied to a display driver fault, power/kernel events, or another subsystem. Docter also notes you can often find more information about application crashes by reviewing the Application log, and for instability/shutdown patterns you “start combing through the logs” in Event Viewer to determine whether the system lost power or crashed. Mike Meyers adds that Event Viewer is the tool used to read and understand Windows logs (Application/System/Setup/Security) for diagnosing what’s happening on a system.

Because the employee needs graphical interface (GUI) access to Linux servers, the best option is VNC (Virtual Network Computing). VNC is specifically designed for remote control and sharing of desktops, meaning it can present the full graphical desktop of the Linux server to the remote user and allow interaction as if they were sitting at the machine. Quentin Docter describes VNC as “a remote control tool for the sharing of desktops,” typically using TCP port 5900, and notes it is similar to RDP but is an open-source protocol; it can support encryption via plug-ins (important for secure remote use). Mike Meyers’ Lab Manual reinforces the key distinction: SSH provides command-line access, but “when you need remote access to the full graphical desktop, you need a remote desktop application,” and many of those use VNC (or RDP).

By contrast, SSH and Telnet are primarily text-console tools (Telnet is also unencrypted/insecure), and WinRM is Windows-focused remote management rather than the standard way to provide GUI access to Linux desktops.

The combination of extreme slowness , browser redirection to unknown sites , outdated antivirus , and blocked access to security settings strongly indicates a malware infection localized to that device (especially since other workstations and network diagnostics are normal). Quentin Docter lists browser redirection as a common security symptom (“Your browser is redirected to websites”) and stresses that if you experience even one of these security symptoms, you should “immediately rectify the security issue or quarantine the system .”

In malware removal best practices, the first operational containment step after verifying symptoms is to isolate/quarantine the infected system to prevent spread, credential theft, or further compromise. Disconnecting the device from the network accomplishes this containment so investigation (logs, scans, offline tools, safe mode, etc.) can be done without risking other systems. Clearing cache (B) is too narrow and doesn’t address blocked security settings/outdated AV. Firewall checks (A) and raising settings (D) don’t contain the threat and may be prevented by the malware itself. Therefore, the next step is to disconnect and investigate .
