CompTIA Updated 220-1102 Exam Questions and Answers by margo

WPA2/AES (Wi-Fi Protected Access 2/Advanced Encryption Standard) is a wireless security standard that supports enterprise mode, which allows a user to use login credentials (username and password) to authenticate to available corporate SSIDs (service set identifiers). TACACS+ (Terminal Access Controller Access-Control System Plus) and Kerberos are network authentication protocols, but they are not wireless security features. Preshared key is another wireless security feature, but it does not use login credentials.

Over time, especially with frequent opening, modification, and saving of large files, a hard disk drive (HDD) can become fragmented. Fragmentation occurs when pieces of individual files are scattered across the disk, leading to longer read and write times, which can significantly slow down the computer. Disk defragmentation reorganizes these fragmented files, placing the pieces closer together on the drive, which improves access time and overall system performance.

• Disk Defragment: Using the Disk Defragment tool on a Windows 10 system with an HDD will help in reorganizing the data more efficiently, thus potentially remedying the slow performance issue.

The Registry Editor (B) is a tool that allows for the viewing and editing of the Windows registry and is generally not used for performance improvement but rather for system settings and configuration adjustments. System Information (C) provides a detailed look at the computer's hardware and system details but does not offer tools for performance improvement. Disk Cleanup (D) can help free up space on the hard drive by removing temporary files and system files that are no longer needed, which can indirectly improve performance but is not the primary tool for addressing fragmentation.

The inability to launch the expected security policy snap-in is likely because the computer is running Windows Home edition, which does not include the Group Policy Editor or certain other administrative tools available in Professional, Enterprise, and Education editions. The Home edition is designed for general consumer use and lacks some of the advanced security and management features found in higher editions.

For scripted network installations requiring new SSDs and keeping HDDs as backup, the necessary tools are: 'net use' to connect to network shares, 'robocopy' to copy files efficiently from the network share to the local drive, and 'diskpart' to manage disk partitions, including initializing and formatting the new SSD. The other options are not relevant to the installation process as described.
