Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It encrypts the query results stored in Amazon S3 at rest
The EncryptionConfiguration parameter in Athena specifies how the query results stored in S3 are encrypted at rest. SSE_S3 means server-side encryption with S3-managed keys. It does not encrypt the query itself, data in transit, or the source data.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It encrypts the query string in transit
Why it's wrong here
The CLI command uses HTTPS for transmission; this parameter is for at-rest encryption of results.
- ✗
It encrypts the data in the source table
Why it's wrong here
The source table encryption is independent of the query result encryption.
- ✗
It enables client-side encryption for the query output
Why it's wrong here
SSE_S3 is server-side encryption, not client-side.
- ✓
It encrypts the query results stored in Amazon S3 at rest
Why this is correct
The parameter defines encryption for the result set in S3.
