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?
Ans B, enable cross region snapshots. That will improve durability. Multi-AZ is not supported with RedShift.
https://aws.amazon.com/about-aws/whats-new/2019/10/amazon-redshift-improves-performance-of-inter-region-snapshot-transfers/
Performance enhancements have been made that allow Amazon Redshift to copy snapshots across regions much faster, allowing customers to support much more aggressive Recovery Time Objective (RTO) and Recovery Point Objective (RPO) Disaster Recovery (DR) policies
Agreed with B. Cross-region snapshots can also be enabled, which will copy incremental changes to a secondary/DR region, allowing for a Redshift cluster to be recovered in another region. Depending upon the snapshot policy configured on the primary cluster, the snapshot updates can either be scheduled, or based upon data change, and then any updates automatically replicated to the secondary/DR region automatically.
I guess the answer is: B - https://aws.amazon.com/blogs/aws/automated-cross-region-snapshot-copy-for-amazon-redshift/
A - NO - because it's about performance
C - NO - there is no option to do this
D - NO - cause each cluster is independent
D. Deploy Amazon Redshift in Multi-AZ.
Amazon Redshift Multi-AZ deployment enhances data durability by replicating the cluster's data to another Availability Zone (AZ) within the same AWS Region. This replication provides high availability and fault tolerance, ensuring that data remains accessible even in the event of an AZ failure. Therefore, Multi-AZ deployment is the appropriate choice to ensure high durability for the data warehouse in case of component failure.
B is answer
Does Amazon Redshift support Multi-AZ Deployments?
Currently, Amazon Redshift only supports Single-Region deployments. To set up a disaster recovery (DR) configuration, you can enable cross-Region snapshot copy on your cluster. This will replicate all snapshots from your cluster to another AWS Region. In the event of a DR event, the snapshots in the replica Region can be restored to create a new cluster. Amazon Redshift also supports cross-Region data sharing, where a consumer cluster can access live data in a producer cluster in another region. This is supported only with Amazon Redshift Serverless and RA3..
This question came to my exam. About 60% of the questions was from here (exactly like here). 25% was from here but the question were asked a bit differently and the other 15% were new to me.
I answered B
Thank you all for your comments. They really helped me understand the concepts better.
thank you for this feedback, im currently going through the questions but ive not come across a comment that remarks about the questions from this site. Thanks again. You didnt say but I hoped you passed you exam.
