Suggested answer: D

Explanation:

Incremental backups are backups that only copy the data that has changed since the last backup, whether it was a full or incremental backup. The main reason to use incremental backups is to minimize the backup time and resources, as they require less storage space and network bandwidth than full backups. Incremental backups can also improve key availability metrics, such as recovery point objective (RPO) and recovery time objective (RTO), but that is not their primary purpose. Reducing costs associated with backups and increasing backup resiliency and redundancy are possible benefits of incremental backups, but they depend on other factors, such as the backup frequency, retention policy, and media type.Reference:CISA Review Manual (Digital Version): Chapter 5 - Information Systems Operations and Business Resilience
