An Apache Beam job reads from Pub/Sub (1-day retention) and writes to Cloud Storage. You need to prevent data loss for a regional outage with a 15-minute RPO. Choose bucket location and recovery strategy.

The correct option ensures data durability and recovery within the 15-minute RPO. A dual-region Cloud Storage bucket with turbo replication provides near real-time replication across two regions, protecting against regional outages. Monitoring Dataflow metrics helps detect outages promptly. Seeking the Pub/Sub subscription back by 60 minutes (or more, up to the 1-day retention) allows recovery of messages that were processed but not yet written to storage before the outage, exceeding the 15-minute RPO to provide a buffer. Starting the Dataflow job in a secondary region enables quick resumption of processing. Incorrect options: Using a multi-regional bucket doesn't guarantee the same RPO as dual-region with turbo replication. Seeking back only 15 minutes might not be enough to recover all uncommitted data, especially with potential processing delays. A regional bucket offers no protection against regional outages.
