CompTIA 220-1202 - CompTIA A+ Core 2 (2026 Exam Update)

Before any change is implemented, it must bedocumentedas part of change management procedures. This ensures transparency, review, and tracking.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Documenting a change is the first step in change management. This includes defining the scope, purpose, impact, and implementation plan before approval or scheduling.”

Before you can accurately understand impact (what will break, what will change, what dependencies exist), you should validate the change in a controlled environment. Mike Meyers’ Lab Manual defines sandbox testing as using a safe place “where you can experiment without messing up the primary system,” typically a virtualized environment that isolates the test machine and enables restore from snapshots. It states sandbox testing “entails checking out new and updated applications without putting the systems and data you depend on at risk.”

The All-in-One guide mirrors this exact best practice for change management, emphasizing that you don’t roll changes into production for many users/systems without “thorough testing and analysis,” and highlights sandbox testing as a documented business process used to evaluate changes safely. In this scenario, the scope is known, so the next “first” practical procedure to evaluate effect is to test it in a sandbox so you can then measure and document impacts based on evidence. A rollback/backup plan is critical, but sandbox testing comes first to determine what safeguards are required.

The correct answer is C. In-place upgrades, because this migration method preserves existing user data, applications, and settings while upgrading the operating system to a newer version. Since a large percentage of users store documents locally, maintaining those files during the upgrade is a key requirement.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, an in-place upgrade replaces the operating system files while keeping user profiles, installed applications, and local data intact. This significantly reduces the risk of data loss and minimizes disruption to users.

The Travis Everett & Andrew Hutz – CompTIA A+ All-in-One Exam Guide explains that clean installs erase the existing OS and require data backup and restoration, which is time-consuming and risky when users store files locally. Zero-touch deployments are automated but typically rely on standardized images and centralized data storage, which does not align with this scenario.

The Mike Meyers / Mark Soper Lab Manual reinforces that in-place upgrades are ideal when preserving user environments is a priority and when systems already meet the requirements for the newer OS.

Because the goal is to upgrade Windows while retaining locally stored documents, in-place upgrades are the most appropriate solution, making C the correct answer.

The first step the CFO should take is to verify the VPN status. When working remotely, access to internal resources such as databases, file servers, and accounting systems typically requires a secure Virtual Private Network (VPN) connection. Without an active VPN tunnel, the application cannot reach internal database servers, resulting in connection errors.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, database connectivity issues during remote work are most commonly caused by missing or disconnected VPN sessions. Internal applications are often restricted to private IP ranges that are inaccessible over the public internet.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide highlights that VPNs are designed to extend the corporate network securely to remote users. If the VPN is disconnected, authentication to internal services will fail even if the application itself launches correctly.

The Mike Meyers / Mark Soper Lab Manual further explains that restarting the PC or updating the application does not resolve network-path issues. Returning to the office is unnecessary if secure remote access is functioning as designed.

Because the error specifically indicates an inability to connect to a database—and not a corrupted application—the most logical and efficient first troubleshooting step is to confirm that the VPN is connected and authenticated.

Whalingis a form of phishing that targets high-profile individuals or involves pretending to be them (e.g., CEOs) to trick lower-level employees into transferring funds or sensitive data.

FromQuentin Docter – CompTIA A+ Study Guide:

“Whaling is a phishing tactic targeting executives or masquerading as one. The attacker crafts emails that exploit authority and urgency to manipulate recipients.”

At large events such as music festivals, cellular towers may become congested due to the high volume of users attempting to connect simultaneously. This congestion causes slow or failed data connections, which explains the email application being unable to sync or connect. This is a common real-world mobile connectivity issue in crowded areas.

A. Lack of storage would prevent saving attachments, not prevent connection attempts.

B. Company firewalls usually don’t affect mobile access unless specific device restrictions are enforced.

D. Organizers do not have the ability to block the internet signal; only carriers manage mobile bandwidth.

UPS batteries are heavy and often located at the bottom of racks to maintain balance. Safe removal requires the use of correct lifting techniques to avoid injury. OSHA and workplace safety standards emphasize ergonomic handling when dealing with heavy equipment.

A. Fire suppression readiness is important for fire safety but not specifically relevant to battery removal.

C. Antistatic bags are for electronic components, not heavy battery modules.

D. A face mask is not generally necessary unless there is a chemical leak, which is not indicated here.

In Windows, accessibility tools such as speech recognition are found under the Ease of Access settings. This section includes options for users who require assistive technologies, including screen readers, magnifiers, and voice control interfaces like speech recognition. Setting up speech recognition allows users to control the system and input text using voice commands.

A. Time and Language is for setting regional preferences and language packs.

B. Personalization adjusts themes, backgrounds, and colors.

C. System includes display, storage, notifications, and power settings, but not accessibility tools.

When a Windows service suddenly stops and then fails to start manually, one of the first places to confirm why it cannot start is the service logon context. A very common root cause is that the account configured on the service cannot authenticate anymore—often because the password changed or the account is locked. Quentin Docter notes that if the service fails due to misconfiguration, “the most likely cause is the user account the service is configured to start with,” and you should ensure “the user account is not locked out.” This aligns with standard service troubleshooting: check Event Viewer (Service Control Manager events) for login failures, then validate the service’s Log On tab configuration and the account state.

The All-in-One guide also reinforces validating services via the Services console and correcting service settings when services fail to start.

Therefore, the best cause given the options is that the service account is locked out (C).
