Explanation
Storage tiering delivers all three listed benefits simultaneously. First, it reduces costs because the majority of data (typically 70–80% is 'cold' or infrequently accessed) can reside on less expensive secondary storage (e.g., SATA, tape, or cloud) instead of costly high-performance primary storage. Second, it allows IT to focus high-performance Tier-1 resources on business-critical data, enabling more aggressive RTO/RPO targets for that data. Third, since secondary-tier data is accessed less frequently, backup windows for that tier can be longer or less intensive without impacting SLAs. Because all three individual statements are valid, 'All of the above' is the correct answer.
