Question
A company uses an Amazon Redshift cluster that runs on RA3 nodes. The company wants to scale read and write capacity to meet demand. A data engineer needs to identify a solution that will turn on concurrency scaling.
Which solution will meet this requirement?
- A. Turn on concurrency scaling in workload management (WLM) for Redshift Serverless workgroups.
- B. Turn on concurrency scaling at the workload management (WLM) queue level in the Redshift cluster. Correct
- C. Turn on concurrency scaling in the settings during the creation of any new Redshift cluster.
- D. Turn on concurrency scaling for the daily usage quota for the Redshift cluster.
Explanation
According to AWS documentation, concurrency scaling can be enabled at the workload management (WLM) queue level within a Redshift cluster. This allows additional clusters to be spun up automatically to handle increased query loads without affecting the original cluster's performance.
