220-1102 Exam Dumps - CompTIA A+ Certification Core 2 Exam

Comprehensive and Detailed In-Depth Explanation:In Windows, when a user changes the network type from private to public, network discovery and file sharing are disabled for security reasons. Public networks are treated as untrusted, and devices on the network are hidden from the user.

B. The Windows Firewall from on to off – Incorrect. Disabling the firewall does not block network visibility.

C. The UAC level to its highest level – Incorrect. User Account Control (UAC) settings control administrative privileges, not network visibility.

D. The file-sharing permissions – Incorrect. File-sharing permissions only affect access to shared folders, not network visibility.

Comprehensive and Detailed In-Depth Explanation:The top command in Linux provides real-time information about CPU usage, running processes, and memory usage. It is equivalent to the Task Manager in Windows.

B. ls – Incorrect. The ls command lists directory contents and does not display processor activity.

C. procmon – Incorrect. Process Monitor (procmon) is a Windows utility, not a Linux command.

D. taskmgr – Incorrect. taskmgr opens Task Manager in Windows but does not exist in Linux.

When a workstation has not received the latest policy changes, the gpupdate command is used to manually apply the latest group policies from the domain controller.

Option A: sfc /scannowThis command is used to scan and repair corrupted system files, not to update group policies.

Option B: gpupdate /forceThis command forces the workstation to reapply all group policies, ensuring that the latest policies are applied immediately.

Option C: chkdsk /yThis command checks the integrity of the file system and fixes logical file system errors, not to update group policies.

Option D: xcopy /ZpThis command is used for copying files and directories, not for updating group policies.

The best protection against physical threats, especially in a common area where the computer is publicly accessible, involves physically securing the hardware.

Option A: Using screen lockScreen locks are good for securing access temporarily but do not protect against physical tampering or theft.

Option B: Installing a privacy screenPrivacy screens prevent visual access but do not secure the hardware.

Option C: Implementing password complexityPassword complexity helps secure digital access but does not prevent physical threats.

Option D: Locking the computer casePhysically securing the case prevents unauthorized individuals from tampering with internal components or stealing the computer.

Option E: Enabling drive encryptionEncryption protects data but does not prevent physical access to the hardware itself.

The net use (Option D) command is used to manage network drives in Windows. It can be used to display and disconnect mapped network drives, making it the correct choice for removing unused network drives.

format (Option A) is used to format disks, not for managing network drives.

netstat (Option B) displays network connections but doesn't manage network drives.

diskpart (Option C) is used for disk partitioning, not network drive management.

rmdir (Option E) is used to remove directories, not network drives.

Comprehensive and Detailed In-Depth Explanation:To minimize costs and user disruption, the technician should:

B. Configure the backup to run after peak hours – This prevents slowdowns during working hours.

D. Use the built-in OS backup utility – This avoids additional licensing costs.

A. Configure the backup to run when the user logs in – Incorrect. This could slow down startup and affect productivity.

C. Use third-party licensed backup software – Incorrect. This would increase expenses.

E. Configure the backup job to run every hour – Incorrect. Frequent backups may slow down the system unnecessarily.

F. Use an external storage device – Incorrect. While useful, it may require additional costs and maintenance.

When dealing with sensitive information, it's crucial to adhere to company policies and procedures. These policies will outline the proper protocols for handling and transporting devices containing sensitive data.

Here's why the other options might not be the best course of action:

A. Remove the HDD and then send the computer for repair: While this might seem like a good way to protect the data, it might not be compliant with company policy. Some policies might require the entire device to be sent for security reasons or to ensure proper diagnosis and repair.

C. Delete the sensitive information before the computer leaves the building: Deleting the data might not be sufficient, as it could potentially be recovered. Also, it might violate data retention policies or hinder the repair process.

D. Get authorization from the manager: While getting manager approval is important, it's essential to first consult the company policies to understand the required procedures.

Recommended Steps:

Check corporate policies: Review the company's policies on data security, device handling, and off-site repairs.

Consult with IT security or management: If the policies are unclear or if you have any questions, seek guidance from the appropriate personnel.

Follow the prescribed procedures: This might involve data encryption, secure data wiping, obtaining necessary approvals, and using approved vendors for off-site repairs.

When dealing with a malware-infected system, isolating the system from the network and disabling System Restore are critical initial steps. The next step in the malware removal process should be:

Perform an antivirus scan: This helps to identify and remove the malware from the system. Running a thorough scan using updated antivirus software is essential to detect and clean any malicious files.

Run Windows updates: This is important for system security but should be done after the malware is removed to avoid further issues.

Reimage the system: This is a more drastic measure and should be considered if the antivirus scan cannot fully clean the system.

Enable System Restore: This should only be done after the system is confirmed to be clean.
