Using Amazon Athena to Query AWS Cost & Usage Reports

Correct Answer: C.

While creating a Table in Amazon Athena, you can specify the path of data to be read using the LOCATION property.

This path is specified as “s3://bucketname/prefix/”

Amazon Athena reads all data stored in this path.

Option A is incorrect.

While specifying location for data in the S3 bucket, a full HTTP path is not required.

Option B is incorrect as Amazon Athena reads all data from the S3 bucket specified & specifying a wildcard * is not required to be added in the LOCATION property.

Option D is incorrect.

While specifying location for data in the S3 bucket, ARN is not required.

Sure, I'd be happy to explain.

To use Amazon Athena to query AWS Cost & Usage reports saved in an S3 bucket in CSV format, you need to specify the S3 bucket path.

The correct format for specifying the S3 bucket path in Amazon Athena is the S3 URI format, which follows the syntax:

s3://bucketname/prefix/

• s3 - specifies the S3 protocol
• bucketname - the name of the S3 bucket where the reports are saved
• prefix - the folder or directory in the bucket where the reports are saved

Option C: s3://bucketname/prefix/ is the correct answer because it follows the correct S3 URI format.

Option A: s3.amazon.com/bucketname/prefix/ is incorrect because it doesn't follow the correct S3 URI format.

Option B: s3://bucketname/prefix/* is incorrect because the * character is a wildcard and is not needed in this case.

Option D: arn:aws:s3:::bucketname/prefix/ is incorrect because it's an Amazon Resource Name (ARN) format and not the correct S3 URI format needed for Amazon Athena.

I hope this explanation helps!
