In this lesson
Prepare for the SAA-C03 exam (AWS Certified Solutions Architect – Associate). In this lesson: RTO and RPO, the four DR strategies, from backup and restore to pilot light, warm standby, and multi-site active-active, durable replicated data with S3 replication, DynamoDB global tables, Aurora Global Database, and AWS Backup, automation and service quotas, and visibility with CloudWatch and X-Ray. Includes three original practice questions.
Preview the topics
- The tracking platform must recover in another Region within about thirty minutes, with low standby costs and no application servers running there. Which strategy fits?
- During a DR test, the standby Region failed to scale out, because the account’s EC2 limits there were still at their defaults. What should the architect have done?
- Tracking requests became two seconds slower, somewhere between API Gateway, three Lambda functions, and DynamoDB, and the team cannot tell which component causes it. What should the architect use?
