An incident report documents key details such as the cause of the outage, steps taken to resolve it, and measures to prevent recurrence. It is a post-mortem analysis often shared with stakeholders to improve future response.
According to the Quentin Docter - CompTIA A+ Complete Study Guide:
"An incident report provides a summary of an event that disrupted normal operations and includes a timeline of what occurred, how the issue was diagnosed and fixed, and who was involved in the resolution".
This is reaffirmed in Travis Everett's All-in-One Guide:
"Documentation after an incident helps technical teams and management review the situation and learn from it. This is formalized in an incident report".

VPN clients often create virtual network adapters. If the software wasn't uninstalled properly or crashed during install, leftover (often hidden) virtual adapters can prevent reinstallation. The proper solution is to delete hidden network adapters using Device Manager (with "Show hidden devices" enabled).
A: OS updates won't fix a leftover driver or adapter issue.
B: Mapping an adapter to the software is not a standard or viable solution.
C: Firmware updates apply to physical adapters, not virtual VPN adapters.

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.

Event Viewer is the primary tool used to investigate system-level errors and logs, including BSODs. When a BSOD occurs, Windows logs the error codes and associated system behavior under "System" logs in Event Viewer. This allows the technician to review crash events, identify error codes (e.g., STOP codes), and pinpoint hardware or driver issues.
B). Performance Monitor is used for real-time performance tracking and trend analysis, not crash logs.
C). System Information displays system specs but not crash logs or events.
D). Device Manager shows device status and driver issues but doesn't retain error logs related to BSODs.

Device encryptionensures that even if someone bypasses biometrics or has physical access to the phone, they cannot read the stored data without the encryption key.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"Encryption is the most effective way to protect data at rest. Even if the device is lost or stolen, encryption ensures the data remains inaccessible without the correct key or passcode."
