CompTIA Updated 220-1102 Exam Questions and Answers by curtis

The correct answer is C. Full Backup.

A Full Backup creates a complete copy of all selected data every time it runs. This method ensures the fastest possible recovery time because all the necessary data is contained in a single backup file.

Since storage space is not a concern, full backups are ideal because they avoid the need to restore multiple incremental or differential backups.

Recovery Time Objective (RTO) is minimized, making full backups the best choice for quick restoration.

Why Other Options Are Incorrect:

A. Differential Backup – Backs up only the data that has changed since the last full backup. While faster to restore than an incremental backup, it still requires both the last full backup and the most recent differential backup for restoration.

B. Synthetic Backup – A synthetic full backup is created by combining previous full and incremental backups without needing to back up data again from the source. While efficient in terms of backup creation, restoration can be slower compared to a traditional full backup.

D. Incremental Backup – Backs up only data that has changed since the last backup (whether full or incremental). While efficient in storage, restoring from incremental backups can be slow because multiple backups must be restored in sequence.

Journaling is a feature that helps maintain the integrity of the filesystem by keeping a record of changes not yet committed to the main file system. This feature is supported by various filesystems, but not all.

Option A: NTFSNTFS (New Technology File System) is a filesystem used by Windows that supports journaling. This makes it resilient to corruption from unexpected shutdowns or crashes by keeping a log of file changes.

Option B: exFATexFAT (Extended File Allocation Table) does not support journaling. It is optimized for flash drives and large files but lacks advanced features like journaling.

Option C: HFSHFS (Hierarchical File System) is an older filesystem used by Apple. HFS+ (also known as Mac OS Extended) supports journaling, but HFS itself does not.

Option D: ext2ext2 (Second Extended File System) is a filesystem for Linux that does not support journaling. Its successor, ext3, introduced journaling.

For an inexpensive file server to share photos and videos while avoiding complicated licensing, the technician should recommend:

Linux: Linux is a free and open-source operating system that is ideal for setting up a file server. It offers robust file-sharing capabilities with minimal licensing complications.

Chrome OS: Designed primarily for lightweight, web-based tasks and not ideal for a file server.

macOS: Requires Apple hardware and involves more complex licensing compared to Linux.

Windows: While capable of being a file server, Windows may involve licensing fees, particularly for server editions.

Network drives can be automatically mapped for users based on Group Policy configuration using log-in scripts. Here’s how it works:

Log-in scripts: These are scripts executed when a user logs in to a domain. They can be configured through Group Policy in Active Directory to map network drives automatically. The scripts can use commands like net use to map drives.

Access control lists (ACLs): While ACLs control permissions for files and folders, they do not automatically map network drives.

Organizational units (OUs): OUs are used to organize users and computers in a directory structure but do not map drives.

Folder redirection: This redirects the path of a folder to a new location, typically on a network share, but it does not automatically map drives.
