Same concept, more angles
2 more ways this is tested on DBS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company is using Amazon RDS for MySQL and needs to monitor for slow queries. Which TWO AWS services can be used to capture and analyze slow query logs? (Choose TWO.)
medium- A.Amazon S3
- ✓ B.Amazon RDS Performance Insights
- C.AWS Config
- D.AWS CloudTrail
- ✓ E.Amazon CloudWatch Logs
Why B: Amazon RDS Performance Insights (Option B) provides database performance analysis and can help identify slow queries by visualizing database load. Amazon CloudWatch Logs (Option E) can ingest and analyze RDS slow query logs by streaming them from RDS. Amazon S3 (Option A) is an object storage service, not a monitoring or analysis service. AWS Config (Option C) is for recording configuration changes, not database logs. AWS CloudTrail (Option D) records API calls for governance, not database-level query logs.
Variation 2. A company is using Amazon Redshift and notices that queries are running slowly. Which TWO system views should be used to identify the cause of the slow queries? (Choose TWO.)
medium- A.STV_TBL_PERM
- B.PG_TABLE_DEF
- ✓ C.STL_QUERY
- D.STL_LOAD_COMMITS
- ✓ E.SVV_QUERY_STATE
Why C: The correct answers are C and E. STL_QUERY contains detailed logs of all queries, including execution times, enabling identification of slow queries after execution. SVV_QUERY_STATE shows currently running queries, helping identify those that are running slowly. Option A (STV_TBL_PERM) is for table permissions, not performance. Option B (PG_TABLE_DEF) shows table definitions. Option D (STL_LOAD_COMMITS) shows load commit information.
