Turbo replication on dual-region buckets
Brackenridge Broadcasting stores newly recorded programs in a Cloud Storage bucket and needs every new object copied to a second region within 15 minutes so that a regional outage loses at most 15 minutes of recordings. Which bucket configuration meets this target?
- A.A dual-region bucket with turbo replication enabled
- B.A multi-region bucket with default replication
- C.A regional bucket with Object Versioning
- D.A regional bucket copied nightly to another region by Storage Transfer Service
Show answer and explanation
Correct answer: A. A dual-region bucket with turbo replication enabled
Why: Turbo replication is offered on dual-region buckets and targets replicating 100% of newly written objects to both regions within 15 minutes. Default replication runs asynchronously and does not have a 15-minute target. Object Versioning keeps older versions in the same region, and a nightly copy could lose up to a day of recordings.
