Videoconferencingplatforms allow real-time face-to-face communication and are ideal for collaborative training sessions involving remote employees.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Videoconferencing tools such as Zoom or Microsoft Teams are specifically designed for real-time communication and training, making them ideal for executive or large-group meetings.”

Keychainis the built-in macOS utility that manages and stores credentials, including passwords and certificates.

According toQuentin Docter – CompTIA A+ Complete Study Guide:

“Keychain Access in macOS is used for managing and storing passwords securely, similar to credential managers in Windows.”

Comprehensive and Detailed Explanation From Exact Extract:

After containment and remediation, one of the final steps in incident response is user education. Since the root cause was a phishing attack, it is essential to educate users about identifying phishing attempts, safe browsing practices, and how to handle suspicious communications. This improves overall security posture and helps prevent future incidents.

A. Installing additional tools may be helpful but is a long-term step.

C. Flashing router firmware is not warranted unless the network hardware is known to be compromised.

D. Suggesting more advanced tools might be excessive given that the EDR successfully contained the incident.

Azero-day vulnerabilitydemands an emergency change to quickly secure the system, even if downtime is needed.

FromMike Meyers' Lab Manual:

“Emergency changes bypass standard scheduling to quickly address critical vulnerabilities that pose immediate risks.” .

Comprehensive and Detailed Explanation From Exact Extract:

A Potentially Unwanted Program (PUP) is software that a user may not have knowingly installed. It often gets bundled with legitimate software and installs without full disclosure. PUPs can affect performance, change system settings, or display unwanted ads but are not necessarily malicious like viruses or ransomware.

A. Viruses replicate and spread; they are generally more harmful and not "bundled" in the same way.

B. Ransomware encrypts files for payment and is deliberately malicious.

D. A Trojan disguises itself as legitimate software to perform malicious actions but is not typically pre-bundled by legitimate publishers.

Event Viewer is the best tool to analyze the root cause of service failures in Windows. It provides detailed logs from system processes, including errors, warnings, and crash reports related to services and applications. When a service starts and stops unexpectedly, Event Viewer will often record the cause, such as dependency failures or access violations.

B. Task Manager shows active processes but doesn't retain logs or causes of failure.

C. Internet Options is used for configuring browser settings, not troubleshooting services.

D. Process Explorer is powerful but more suited for live monitoring and detailed process trees, not post-failure log analysis.

Comprehensive and Detailed Explanation From Exact Extract:

Resource Monitor provides real-time monitoring of system performance and resource usage, including CPU, memory, disk, and network usage. It helps technicians identify performance bottlenecks (e.g., high memory or CPU usage) that can cause slowdowns in applications over time without producing crash errors.

A. Reliability history logs application crashes or errors — not helpful if the app doesn’t crash.

B. Computer Management is a broad utility with limited real-time monitoring capability.

D. Disk is too vague — tools like CHKDSK can help with disk errors but not general performance degradation.

An MSDS providessafety and emergency procedures, such as what to do if a battery leaks or catches fire. It is not a technical or setup guide.

FromTravis Everett – CompTIA A+ All-in-One Exam Guide:

“An MSDS contains safety information, including handling, storage, and emergency procedures related to potentially hazardous components like UPS batteries.”

ApplicationsandLibraryare core system directories in macOS. TheApplicationsfolder contains installed applications. TheLibraryfolder contains support files, preferences, and other system-related files.

From theQuentin Docter – CompTIA A+ Complete Study Guide:

“macOS organizes system and user files into several key folders. Among them, Applications and Library are standard system folders where apps and related files are stored.”

Comprehensive and Detailed Explanation From Exact Extract:

Standard Operating Procedures (SOPs)guide technicians through consistent and complete processes, including documentation.

FromTravis Everett – All-in-One Exam Guide:

“SOPs ensure that all required steps—such as data collection and issue description—are followed in every support interaction.”
