A moderate mix of ETL design, event-driven ingestion, and troubleshooting around S3 event notifications. The scenarios stayed concrete without drifting into vague theory.
The practice set leans heavily on Athena queries, IAM roles, and data pipeline troubleshooting. It was useful, though a couple of explanations felt brief.
Good spread of AWS Glue catalog work, Kinesis ingestion, and Redshift loading patterns. Some items took a second read, especially around partitioning and schema evolution.
Covers S3, Glue jobs, and basic Lake Formation permissions in a way that feels practical. A few questions were worded more tightly than I expected, but the topics were on target.

65 multiple choice and multiple response questions in 130 minutes. 15 of them are unscored. You take it at a test center or online with a proctor.

Three years.
Take a test, then read the explanation for every question you miss. Many questions ask for the option with the least operational overhead, so learn which services are serverless and managed.
