Spear phishingtargets a specific individual using personalized tactics, as seen in emails impersonating a CEO to deceive a secretary.
FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:
"Spear phishing targets specific individuals or roles within an organization using tailored messages to increase success rates."

The correct answer is D. Internal wiki, because an internal wiki is specifically designed to store, maintain, and centrally manage organizational knowledge, including deployment procedures, configuration standards, and troubleshooting documentation. Large-scale software deployments require accurate, up-to-date, and version-controlled instructions that can be accessed by multiple technicians.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, organizations commonly use internal knowledge bases or wikis to document standard operating procedures (SOPs), deployment guides, and escalation paths. These platforms allow content to be updated quickly as procedures evolve, which is essential for complex deployments.
The Travis Everett & Andrew Hutz - CompTIA A+ All-in-One Exam Guide emphasizes that internal wikis support collaboration and consistency. Unlike emails or files stored on individual systems, a wiki provides a single source of truth, reducing the risk of technicians following outdated or incorrect instructions.
The Mike Meyers / Mark Soper Lab Manual further explains that while file servers may store installation files and emails may contain announcements, neither is suitable for maintaining structured, searchable deployment documentation. A user's desktop is never an appropriate location for organizational procedures.
Because large-scale deployments require centralized, standardized, and continuously updated documentation, the most appropriate reference location is an internal wiki, making D the correct answer.

SSH (Secure Shell) allows encrypted console sessions to access and administer remote servers.
From Quentin Docter - Complete Study Guide:
"Secure Shell (SSH) provides an encrypted console session to manage Linux, UNIX, or network devices securely over TCP port 22." .

Hash values(like SHA256) are published by vendors to verify file integrity. A match confirms the file hasn't been tampered with.
FromTravis Everett - CompTIA A+ All-in-One Exam Guide:
"Use hash values to ensure downloaded software matches the vendor's published version and hasn ' t been modified."

The correct answer isVNC (Virtual Network Computing). VNC is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. It is platform- independent and widely supported on Linux, which makes it ideal for providinginteractive remote support for a Linux-based operating system. It allows the technician not only to view the remote desktop session but also tocontrol it, fulfilling the need to see and interact with the user's session.
A). VPN(Virtual Private Network) creates a secure tunnel to a network but doesnot provide desktop sharing or session controlby itself.
C). SSH(Secure Shell) provides secure command-line access to Unix/Linux systems but does not offergraphical desktop interaction, which is a requirement in this case.
D). RDP(Remote Desktop Protocol) is primarily a Microsoft protocol, and although it can be made to work on Linux, it isnot natively supported on legacy Linux systems, and thusless suitablethan VNC in this scenario.
CompTIA A+ 220-1102 Core 2 Objective Reference:
Objective 1.8 - Given a scenario, use features and tools of the operating system.
Under this objective, candidates are expected to be familiar with remote access technologies, includingRDP, SSH, and VNC, and understand their appropriate uses and limitations on different platforms such as Windows and Linux.
