Which of the following prevents forced entry into a building?
Correct Answer:
D
Comprehensive and Detailed Explanation From Exact Extract:
A bollard is a sturdy physical barrier—often a steel or concrete post—designed to prevent
vehicles or unauthorized individuals from ramming into or entering secure areas of a building. It provides physical security and is commonly used outside entrances to prevent forced entry.
* A. PIV (Personal Identity Verification) cards are used for identity access control, not physical blocking.
* B. Motion lighting may deter activity but doesn??t physically prevent entry.
* C. Surveillance records activity but cannot stop a forced entry. Reference:

Which of the following is found in an MSDS sheet for a battery backup?
Correct Answer:
B
Comprehensive and Detailed Explanation From Exact Extract:
An MSDS (Material Safety Data Sheet), now commonly referred to as SDS (Safety Data Sheet), is a document that provides detailed information on the properties of a particular substance. It includes safety guidelines and emergency procedures related to handling, exposure, fire hazards, and first aid—not installation or configuration instructions.
For a battery backup (UPS device), the MSDS would include emergency procedures such as what to do in case of a chemical spill, exposure to battery acid, or fire hazard due to overheating or chemical leakage. This ensures the safety of personnel and complies with hazardous materials handling regulations.

An administrator received an email stating that the OS they are currently supporting will no longer be issued security updates and patches. Which of the following is most likely the reason the administrator received this message?
Correct Answer:
B
Comprehensive and Detailed Explanation From Exact Extract:
Operating systems periodically reach a status known as "end of life" (EOL), at which point the developer (e.g., Microsoft, Apple) ceases to provide security updates, patches, or technical support. When this happens, the OS becomes vulnerable and non-compliant with security best practices, which is why organizations typically receive advance notifications from vendors or support teams.
* A. Manufacturer support expiration only applies to hardware, not OS patching.
* C. Security software may be upgraded or removed, but that does not affect patching the OS itself.
* D. The release of a new version doesn??t automatically stop updates for the current version. Reference:
CompTIA A+ 220-1102 Objective 1.3: Given a scenario, use appropriate Microsoft operating system features and tools.

Which of the following methods involves requesting a user's approval via a push notification to verify the user's identity?
Correct Answer:
B
Comprehensive and Detailed Explanation From Exact Extract:
Authenticator apps (e.g., Microsoft Authenticator, Google Authenticator, Duo) often support push notifications. When the user logs in, the app sends a push to their mobile device, prompting the user to approve or deny the authentication request — a common and user- friendly form of multi-factor authentication (MFA).
* A. Phone call verification is a separate method involving voice-based confirmation.
* C. Hardware tokens generate one-time codes but do not send push notifications.
* D. SMS sends a text message with a code — again, no push mechanism. Reference:

An end user's laptop is having network drive connectivity issues in the office. The end user submits a help desk ticket, and a support technician is able to establish a remote connection and fix the issue. The following day, however, the network drive is disconnected again. Which of the following should the technician do next?
Correct Answer:
C
Comprehensive and Detailed Explanation From Exact Extract:
Since the issue has recurred after a temporary fix, it is likely a deeper or persistent configuration or server issue. Escalating the ticket to the next tier of support (e.g., network or system administrator) ensures further investigation and permanent resolution. Escalation is part of the standard support protocol when issues reoccur despite initial troubleshooting.
* A. Rechecking remotely may confirm the issue, but doesn??t resolve it long term.
* B. Providing documentation helps the user but doesn??t solve the root cause.
* D. Keeping the ticket open is passive and doesn??t address the recurring issue. Reference:
