220-1202 Exam Dumps - CompTIA A+ Questions and Answers

The correct answer is A. Hashing, because hashing is specifically designed to verify file integrity and detect whether a file has been altered after its original creation or distribution. A hash is a fixed-length value generated by running a file through a hashing algorithm such as SHA-256 or SHA-1. Even a single-bit change in the file will produce a completely different hash value.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, hashing is commonly used to validate downloaded software by comparing the calculated hash of the downloaded file with the hash published by the vendor. If the two values match, the technician can be confident that the file has not been modified or tampered with.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that hashing ensures integrity, not confidentiality or authentication. SSL certificates secure data in transit, but they do not validate files after download. Plug-ins and extensions provide additional browser functionality but have no role in verifying file integrity.

The Mike Meyers / Mark Soper Lab Manual reinforces that hashing is a standard best practice in secure software deployment and malware prevention. It allows technicians to confirm that files are exactly as the publisher intended.

Because the requirement is to confirm that files have not been modified, hashing is the correct and most reliable method, making A the correct answer.

In a domain environment, printers are typically deployed via a print server. Users can browse available printers on the server and install them directly.

All-in-One Exam Guidementions:

“In a corporate domain, printers are managed via a centralized print server. Users can select the desired printer from the server’s shared list.”

FromAll-in-One Exam Guide:

“Browser hijackers often install as extensions and change homepage settings. Removing these extensions and resetting the startup configuration typically resolves the issue.”

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.”

A zero-day vulnerability demands an emergency change to quickly secure the system, even if downtime is needed.

From Mike Meyers' Lab Manual:

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

The correct answer is A. Reinstalling the application, because the issue appears to be application-specific rather than system-wide. The problem only affects one game, the operating system is fully updated, and there are no storage constraints. These indicators strongly suggest corrupted application data or a faulty app installation.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, when a single application crashes repeatedly, the first recommended troubleshooting step is to remove and reinstall the app. This clears corrupted files, resets application settings, and ensures the latest compatible version is installed.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that factory resets should only be used as a last resort, as they are disruptive and erase user data. Disabling background applications may help performance issues but does not typically resolve persistent crashes tied to one specific app.

The Mike Meyers / Mark Soper Lab Manual further clarifies that date and time misconfiguration usually affects authentication or certificate validation, not game stability.

Because the symptoms are isolated to a single application and basic system factors have already been ruled out, reinstalling the application is the most appropriate first troubleshooting step, making A the correct answer.

Comprehensive and Detailed Explanation From Exact Extract:

Image deployment is the fastest and most efficient method for installing operating systems on multiple machines. It involves creating a pre-configured image of an OS and deploying it across systems using tools like Windows Deployment Services (WDS) or third-party imaging solutions. This method saves time and ensures consistency across all devices.

A. Physical media is slow and not scalable.

B. Mountable ISOs are useful but still require manual installation.

C. Manual installation is time-consuming and not suitable for large-scale deployment.

SSH (Secure Shell) allows encrypted console sessions to access and administer remote servers.

From Quentin Docter – Complete Study Guide:

“Secure Shell (SSH) provides an encrypted console session to manage Linux, UNIX, or network devices securely over TCP port 22.” .

Comprehensive and Detailed Explanation From Exact Extract:

Windows Helloprovides alternative sign-in options including facial recognition, fingerprint scans, and PINs, reducing dependence on passwords.

FromAll-in-One Exam Guide:

“Windows Hello offers a range of biometric and PIN-based login methods designed to simplify access while enhancing security.”

“It can be used in place of a password, ideal for users who frequently forget credentials.”

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.
