Exam CLO-002 topic 1 question 44 discussion

(D) Archiving is correct. RPO is a disaster recovery (DR) factor. Operational state replication, whether synchronous (AZs) or asynchronous (geo-redundancy) is NOT backup. We are fortunate when our DR can benefit from operational replicated data, but to rely on operational replication SOLELY as one’s DR backup-restore option is foolish at best and professional malpractice at worst. A straightforward example: as part of their operations, availability zones replicate data/resources among “nearby” data centers (DC) within the zone. A natural disaster may have expansive impact – clobber an entire zone – thus eliminating both the operational data and its replicated copy. For best practice DR, you must include archived backups.

Correct is B)

Yes, I’m sure that B. Replication is the correct answer, not D. Archiving. Explanation: • Replication: This involves creating real-time or near-real-time copies of data across multiple locations or systems. The primary goal of replication is to ensure data availability and to minimize data loss in the event of a failure, which directly impacts and reduces the Recovery Point Objective (RPO). RPO is about minimizing the amount of data loss during a disaster, and replication is the best method to achieve a lower RPO.

B is correct

B. Replication : Archiving refers to storing data for long-term retention (usually in COLD backup), typically for compliance or regulatory purposes, and may not necessarily improve the RPO Replication.

Replication: Data availability Locality: Location or proximity Backup: Disaster recovery
