Exam SY0-701 topic 1 question 591 discussion

The correct answer is: A. Snapshots Here's why: A. Snapshots Snapshots are point-in-time copies of data on a file system or storage volume. Organizations use them to quickly restore files or entire systems to a previous state, minimizing data loss in the event of corruption, deletion, or failure. They’re commonly used for backup and recovery purposes. B. Journaling Journaling is a technique used by some file systems to keep track of changes not yet committed to the main file system. It helps prevent file system corruption, but it’s not designed for restoring lost data, just for maintaining file system integrity. C. Obfuscation Obfuscation refers to making data unclear or unreadable to unauthorized users. It’s a security/privacy technique, not a data recovery or backup method. D. Tokenization Tokenization replaces sensitive data with non-sensitive equivalents (tokens). It's used for data security and privacy, not for data recovery or minimizing loss.
