CompTIA A+ Practice Test (220-1102)

System file checker (SFC) differs from Windows repair in that it can be used to fix certain system files.It can perform a scan to find corrupted files and fix those that need to be repaired. Windows repair replaces all system files.

BitLocker provides disk encryption, which helps to protect data by encrypting the entire drive. This ensures that unauthorized users cannot access the data without the proper authorization. It is not related to internet protection, firewall settings, or application installations directly.

To restore the server to its most recent state after a crash on Thursday morning, you need the full backup from Sunday and the differential backup from Monday. Differential backups capture all changes since the last full backup, so the Monday differential includes all changes made up to and including Monday.

The full backup from Sunday and the differential backup from Wednesday is incorrect, as the question states the available backups are from Sunday and Monday, not Wednesday.

Upgrading the workstations with dedicated graphics cards that have at least 2GB of VRAM is necessary to meet the application's system requirement for graphic performance. Integrated graphics share memory with the CPU and typically do not provide the same level of performance as a dedicated graphics card, which has its own memory (VRAM).

Ensuring the antivirus definitions are up to date is critical because new malware variants are constantly being created, and up-to-date definitions are required to identify and remove them. Running a scan without updated definitions might not catch the latest threats. Restoring to a known good backup does not prevent future infections and might reintroduce the same malware if the backup is compromised. Disabling the antivirus might be performed during troubleshooting but is not a preventive measure. Completely reinstalling the operating system would eliminate current malware but does not prevent future infections and is an extreme measure that should only be taken if all other options fail.

This statement is True.

This is because a blue screen of death (BSOD) is a well-known indicator of critical problems within the Windows operating system, often caused by hardware or driver issues. Sluggish performance may also occur but does not specifically correlate to the extreme error that a BSOD represents.

The correct answer is 'To copy files and directories from one location to another with advanced options'. Robocopy, short for 'Robust File Copy', is designed to handle file replication with several options like copying file permissions, attributes, and mirroring directory structures, which makes it more capable than simple copy commands.

The Real-Time Clock (RTC) ensures the computer is able to keep time even when powered off, typically using a small battery like the CMOS battery.

The correct command for displaying IP configuration details, including the subnet mask and default gateway, is 'ipconfig'. This command provides essential network information for troubleshooting and configuration.

The other options, while related to networking, do not provide the specific details required for this task. For instance, 'ping' tests connectivity to another device but doesn't display IP settings, and 'netstat' shows active connections, which is unrelated to retrieving IP configuration.

General Data Protection Regulation (GDPR) is a governmental regulation that applies to companies that conduct business in the European Union.

The principle of least privilege ensures that users have only the permissions they need to complete their tasks, reducing the risk of accidental or intentional misuse of resources.

Other options involve more general access controls, which do not focus on minimizing permissions.

This statement is True.

The net use command is used to connect to shared network resources, such as shared folders or printers, by mapping them to a local drive letter. This allows the user to access the resource as if it were a local drive.

Enabling developer mode on a mobile device can expose the device to security risks because it allows the user to access advanced development-related settings that can alter the device's functionality. These settings, if misconfigured, can make the device vulnerable to malicious attacks or unintentionally introduce security weaknesses.

The purpose document should describe why the change is needed and has been requested, for example to patch a known security vulnerability or to fix a bug or issue.

Checking the IP configuration is important because resolving an IP address conflict or ensuring correct settings is crucial for network access. Invalid or conflicting IP configurations can prevent a device from accessing the network. The other options are less immediate in tackling network access issues directly, as certificate problems usually affect specific services and the laptop already has Wi-Fi enabled.
