Exam SY0-701 topic 1 question 448 discussion

A hot site is a fully operational and continuously updated replica of the primary site, including servers, data, and applications. It allows for the quickest recovery (lowest RTO, Recovery Time Objective) and the least data loss (lowest RPO, Recovery Point Objective) because the data is synchronized in near real-time with the primary site. If the primary site fails, operations can resume almost immediately from the hot site

Journaling involves continuously logging all changes made to a database. This allows for near real-time recovery, which helps minimize both RTO (how quickly you can recover) and RPO (how much data can be lost). Since journal entries capture every transaction, you can recover to the exact point of failure with minimal data loss and downtime.

The correct answer is: C. Journaling Explanation: Journaling is a technique used to keep track of changes made to a database, which allows for the fastest recovery point and recovery time in case of failure. When a database is using journaling, the system records every transaction, so if there is an issue, the system can quickly roll back to the most recent state or recover up to the point of failure. This minimizes both RTO (Recovery Time Objective) and RPO (Recovery Point Objective), as you can quickly restore the system and minimize data loss.

Journaling provides the lowest RTO and RPO because it continuously records changes, ensuring minimal data loss and quick recovery.

Should be D. Hot site

Hot site: A hot site is a fully operational, synchronized duplicate of the primary site, including real-time replication of data. This setup ensures the lowest RTO (immediate switchover) and RPO (minimal to no data loss), making it the most effective for critical systems requiring high availability.
