Comprehensive and Detailed Explanation From Exact Extract:

Once a malware incident has been confirmed, the immediate next step is to contain the threat. Quarantining infected systems prevents the malware from spreading to other devices and isolates the malicious code for further analysis or remediation.

B. Educating end users is important but occurs later in the incident response process.

C. Disabling System Restore is part of cleanup, not containment.

D. Updating and scanning should occur after the system is quarantined to prevent further infection or spread.

If unauthorized or non-standard applications are appearing on systems and users are receiving licensing prompts, it’s likely users are installing software themselves. Removing users from the local administrators group will prevent them from installing software without approval and reduce the likelihood of introducing unapproved or malicious programs.

A. Deploying a PKI helps with secure communications but doesn’t address user software installation rights.

C. Blocking suspicious websites is helpful but doesn’t prevent local installations.

D. Stricter UAC may add prompts but can still be bypassed by admin users.

The first step in the IT change management process is to identify and propose the change. In this case, the technician notices a need (end-of-life network switches), so the appropriate action is toformally propose a change. This proposal would be documented and submitted for approval before any planning or implementation occurs.

According to the CompTIA A+ 220-1102 objectives under Operational Procedures (Domain 4.0), the change management process follows these typical steps:

Submit a change request (Propose the change)

Review and approval (Approve the change)

Planning and scheduling (Schedule the change)

Implementation

Documentation and review

Therefore, proposing the change is the correct first step in accordance with standard ITIL-based change management practices.

Credential managers or password vaults (e.g., Windows Credential Manager, KeePass, or LastPass) store passwords securely. The integrity of such tools heavily depends on the strength of the master password protecting the vault. If compromised, all saved credentials could be exposed. Therefore, setting a secure master password is crucial.

A. Login time restrictions are general user account settings, not specific to credential managers.

C. TPM is used more commonly for full disk encryption, not specifically required for password managers.

D. The lock screen protects general access but does not protect stored credentials alone.

Aclean installensures all malware is eliminated by completely wiping and reinstalling the OS. System restore or repair may leave traces.

FromQUENTIN DOCTER - COMPTIA A+ COMPLETE study GUIDE:

“If malware cannot be completely removed, perform a clean installation of the operating system. This ensures no remnants remain on the machine.”

Comprehensive and Detailed Explanation From Exact Extract:

BitLocker To Go is a Microsoft encryption feature specifically designed for removable drives such as USB flash drives and external hard drives. It allows users to protect the data on these devices by requiring a password to decrypt the contents, thereby preventing unauthorized access in the event the device is lost or stolen.

A is correct because BitLocker To Go is directly tied to password-protecting removable media.

B and C are unrelated to BitLocker To Go; Secure Boot and VPN encryption are entirely different security layers.

D applies to BitLocker (not BitLocker To Go) and full disk encryption on internal drives using TPM.

Comprehensive and Detailed Explanation From Exact Extract:

In the context of artificial intelligence, "hallucinations" refer to instances where an AI system generates information that is plausible-sounding but factually incorrect or entirely fabricated. This is a known limitation of large language models, including generative AI tools.

A. Data privacy refers to the protection of personal or sensitive data, not content accuracy.

C. Appropriate use relates to ethical and policy-based concerns, not factual correctness.

D. Plagiarism involves presenting someone else's work as your own — this situation is about accuracy, not ownership.

Comprehensive and Detailed Explanation From Exact Extract:

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.

Cloud-based software often enforcesdevice limitsper license. Before reinstallation or switching software, checking license allocations is the most logical first step.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Many cloud apps enforce user or device count restrictions. When an install fails, check licensing before troubleshooting other areas.”

Comprehensive and Detailed Explanation From Exact Extract:

RAM is an electrostatic-sensitive component. When removing or transporting RAM modules, they should be stored in antistatic bags to protect against electrostatic discharge (ESD), which can damage the memory. This is a standard best practice in hardware handling.

A. Demagnetization is not applicable to RAM.

C. Plugging in power to ground is not safe or recommended for static protection.

D. Installing identical memory pairs is applicable for dual-channel configuration, but not directly related to transporting or handling RAM.
