DEA-C01 Data Operations and Support Practice Question
A company runs a data pipeline on AWS Glue that processes streaming data from Amazon Kinesis Data Streams and writes results to an Amazon Redshift cluster. The pipeline has been running smoothly, but recently the Glue job started failing with 'ResourceNotFoundException' for the Redshift table. What should the data engineer check first?

Correct answer & explanation
✓
Verify that the target Redshift table exists and was not dropped or renamed.
The error indicates the table does not exist or was deleted. Option B is wrong because IAM role issues would cause Access Denied, not ResourceNotFoundException. Option C is wrong because network issues would cause timeout or connection refused. Option D is wrong because schema changes could cause type mismatch but not ResourceNotFoundException.
