Whalingis a form of phishing that targets high-profile individuals or involves pretending to be them (e.g., CEOs) to trick lower-level employees into transferring funds or sensitive data.
FromQuentin Docter - CompTIA A+ Study Guide:
"Whaling is a phishing tactic targeting executives or masquerading as one. The attacker crafts emails that exploit authority and urgency to manipulate recipients."

The requirement is graphical interface access to Linux servers. SSH is excellent for secure command-line access, but it is not a GUI remote desktop by default. Mike Meyers explains this distinction clearly: "The kind of remote command-line access you can get with SSH is great... When you need remote access to the full graphical desktop, you need a remote desktop application. " He then notes that most remote desktop tools use "either the Remote Desktop Protocol (RDP) or Virtual Network Computing (VNC) ," and that TightVNC is cross-platform.
The All-in-One guide repeats the same point: for a full graphical desktop, remote desktop applications commonly use RDP or VNC , and VNC solutions are cross-platform. Since the servers are Linux and the employee needs GUI access, VNC is the best answer among the choices. Telnet is insecure (clear-text credentials), and WinRM is Windows-focused management. Therefore, choose VNC (B) .

The correct answer is B. Task Manager, because Task Manager allows technicians to view, manage, and terminate running processes, including those that are frozen or unresponsive. If an application process is already running but not responding, launching it again will fail until the existing process is stopped.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, Task Manager is the primary Windows tool for troubleshooting application hangs, excessive resource usage, and nonresponsive programs.
Technicians can end the task and relaunch the application cleanly.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that Resource Monitor provides detailed performance metrics but is not optimized for quickly terminating frozen applications. Event Viewer logs errors but does not resolve active process issues.
The Mike Meyers / Mark Soper Lab Manual reinforces that Registry Editor should never be used for live application troubleshooting due to the risk of system instability.
Because the issue involves an unresponsive background process, Task Manager is the fastest and safest tool to resolve the problem, making B the correct answer.

The correct answer is C. man, which stands for manual. The man command is used in Linux and UNIX-based operating systems to display the official documentation for commands, configuration files, and system calls.
This documentation includes descriptions, syntax, available options, and usage examples.
The Quentin Docter - CompTIA A+ Complete Study Guide explains that Linux relies heavily on built-in documentation accessible from the command line. The man pages are considered the authoritative reference for how a command works and what options it supports. For example, running man cp displays documentation for the file copy command.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide emphasizes that learning to use man is essential for Linux administration and troubleshooting. Unlike graphical help systems, man pages are always available locally and do not require internet access.
The Mike Meyers / Mark Soper Lab Manual clarifies that chmod changes file permissions, cat displays file contents, and sudo allows commands to be run with elevated privileges. None of these commands provide documentation about other commands.
Because the question specifically asks about reading another command's documentation, the Linux command designed for that exact purpose is man, making C the correct answer.

The best option is to create a lower-security network exclusively for the console. Many retro or legacy gaming consoles only support older Wi-Fi security standards such as WPA or even WEP, and they cannot connect to modern WPA2 or WPA3 networks. Downgrading the entire primary network would significantly weaken overall security, which is not recommended in any environment.
The Quentin Docter - CompTIA A+ Complete Study Guide explains that legacy devices often lack firmware support for modern encryption standards and should be isolated rather than integrated directly into secure networks. Creating a separate SSID with reduced security limits exposure while still allowing connectivity for the unsupported device.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide emphasizes that lowering security settings on a primary router-even temporarily-introduces unnecessary risk. Switching encryption modes back and forth can also cause configuration instability and expose the network during the downgrade window.
The Mike Meyers / Mark Soper Lab Manual further reinforces the concept of network segmentation as a best practice. By creating a dedicated network for legacy or insecure devices, administrators reduce the attack surface and prevent lateral movement to sensitive systems.
Using a wired Ethernet adapter may not be supported by the console, and adding an older router introduces unmanaged vulnerabilities. Therefore, isolating the console on a separate, lower-security wireless network is the safest and most practical solution.
