Q1323. A company uses Amazon Redshift for its data warehouse. The company wants to ensure high durability for its data in case of any component failure.What should a solutions architect recommend?

Correct Answer: B. Enable cross-Region snapshots.

Explanation

To ensure high durability for data in Amazon Redshift in case of component failures, the best recommendation is:Correct Answer:B. Enable cross-Region snapshots.Why This is the Best Solution?\1. Cross-Region Snapshots Provide Geographic RedundancyAmazon Redshift snapshots are point-in-time backups of your data warehouse. Cross-Region snapshots replicate these backups to another AWS Region, ensuring:Protection against Region-wide failures (e.g., natural disasters, data center outages). Compliance with disaster recovery (DR) requirements (e.g., financial regulations). Minimal RTO (Recovery Time Objective)--you can restore from a snapshot in another Region if needed.\2. Redshift Does Not Support Multi-AZ Deployments (Unlike RDS) D. Deploy Amazon Redshift in Multi-AZ is incorrect because:Redshift does not have a Multi-AZ option (unlike Amazon RDS). Redshift clusters are single-Region deployments with compute node redundancy (managed by AWS), but no automatic failover between Regions.\3. Other Options Do Not Directly Improve DurabilityA. Enable concurrency scaling Improves query performance under high concurrency but does not enhance durability.C. Increase the data retention period Keeps snapshots longer but does not protect against Region-wide failures (if snapshots are stored in the same Region).Best Practices for Redshift DurabilityEnable automated snapshots (default retention: 1 day, configurable up to 35 days). Configure cross-Region snapshot copying (manual or via AWS Backup). Test disaster recovery (DR) by restoring from a snapshot in another Region. Consider using AWS Backup for centralized management of Redshift snapshots across Regions.ConclusionThe best way to ensure high durability for Amazon Redshift data is:B. Enable cross-Region snapshots (geographic redundancy).Other options either do not improve durability (A, C) or are not supported (D).
