Topic 1 Question 242
You have designed an Apache Beam processing pipeline that reads from a Pub/Sub topic. The topic has a message retention duration of one day, and writes to a Cloud Storage bucket. You need to select a bucket location and processing strategy to prevent data loss in case of a regional outage with an RPO of 15 minutes. What should you do?
- 1. Use a dual-region Cloud Storage bucket.
  2. Monitor Dataflow metrics with Cloud Monitoring to determine when an outage occurs.
  3. Seek the subscription back in time by 15 minutes to recover the acknowledged messages.
  4. Start the Dataflow job in a secondary region.
- 1. Use a multi-regional Cloud Storage bucket.
  2. Monitor Dataflow metrics with Cloud Monitoring to determine when an outage occurs.
  3. Seek the subscription back in time by 60 minutes to recover the acknowledged messages.
  4. Start the Dataflow job in a secondary region.
- 1. Use a regional Cloud Storage bucket.
  2. Monitor Dataflow metrics with Cloud Monitoring to determine when an outage occurs.
  3. Seek the subscription back in time by one day to recover the acknowledged messages.
  4. Start the Dataflow job in a secondary region and write in a bucket in the same region.
- 1. Use a dual-region Cloud Storage bucket with turbo replication enabled.
  2. Monitor Dataflow metrics with Cloud Monitoring to determine when an outage occurs.
  3. Seek the subscription back in time by 60 minutes to recover the acknowledged messages.
  4. Start the Dataflow job in a secondary region.

  Low RPO: Dual-region buckets offer synchronous replication, ensuring data is immediately available in both regions, aligning with the 15-minute RPO.
  
  Turbo Replication: enabling turbo replication can further reduce replication latency to near-real-time for even stricter RPO requirements.
  
  Resilient Data Storage: Dual-region buckets ensure data availability even during regional outages, protecting processed data.
  
  Fast Recovery: Reprocessing from the last 15 minutes of acknowledged messages minimizes data loss and downtime.
