AIF-C01 Practice Question: Using Amazon Comprehend to extract entities from…
A company is using Amazon Comprehend to extract entities from customer support tickets. The compliance team requires that the text sent to Comprehend be encrypted in transit and that Comprehend does not store any data beyond the processing time. How should the company configure the API call?
⚠ Common exam trap
Many exam-takers confuse encryption in transit with encryption at rest or data retention controls, leading them to overcomplicate the solution with KMS, SSE, or VPC endpoints when the simple use of HTTPS and the stateless nature of the API already meet the requirements.

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
✓
Use the HTTPS endpoint for the DetectEntities API and rely on Comprehend's stateless design
Amazon Comprehend's DetectEntities API is inherently stateless—it does not store any text or results beyond the processing time required to generate the response. By using the HTTPS endpoint, the company ensures encryption in transit via TLS, satisfying the compliance requirement without additional configuration. Comprehend does not persist data from synchronous API calls, so no data is retained after the response is returned.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Encrypt the text using AWS KMS before sending it to Comprehend
Why it's wrong here
Comprehend cannot process encrypted text; it requires plaintext input.
- ✗
Use the AWS SDK with server-side encryption enabled for the API call
Why it's wrong here
Server-side encryption applies to data at rest, not in transit; the API call payload is plaintext.
- ✗
Create a VPC endpoint for Comprehend and send requests over the private network
Why it's wrong here
VPC endpoint provides private connectivity but does not inherently encrypt the payload; HTTPS should be used.
- ✓
Use the HTTPS endpoint for the DetectEntities API and rely on Comprehend's stateless design
Why this is correct
HTTPS provides encryption in transit; Comprehend does not store data after processing.
