Amazon Exam DAS-C01 Topic 7 Question 89 Discussion

Actual exam question for Amazon's DAS-C01 exam

Question #: 89
Topic #: 7

A company is using an AWS Lambda function to run Amazon Athena queries against a cross-account AWS Glue Data Catalog. A query returns the following error:

HIVE METASTORE ERROR

The error message states that the response payload size exceeds the maximum allowed payload size. The queried table is already partitioned, and the data is stored in an

Amazon S3 bucket in the Apache Hive partition format.

Which solution will resolve this error?

AModify the Lambda function to upload the query response payload as an object into the S3 bucket. Include an S3 object presigned URL as the payload in the Lambda function response.

BRun the MSCK REPAIR TABLE command on the queried table.

CCreate a separate folder in the S3 bucket. Move the data files that need to be queried into that folder. Create an AWS Glue crawler that points to the folder instead of the S3 bucket.

DCheck the schema of the queried table for any characters that Athena does not support. Replace any unsupported characters with characters that Athena supports.

Hmm, it sounds like the table is already partitioned, so that's good. But the payload size issue is a real head-scratcher. I'm leaning towards option A, since uploading the response to S3 and returning a pre-signed URL seems like a clever way to work around the payload size limit. But I'd love to hear what the others think.

Whoa, this question seems pretty tricky! A 'HIVE METASTORE ERROR' due to a response payload size exceeding the maximum allowed? That's a pretty specific issue. I'm not sure I'd know where to start, but I'm definitely curious to see what the other candidates think.
