The answer is that no action is needed, because Amazon Comprehend automatically encrypts all data at rest using AES-256 by default. This means that every document you submit for analysis, along with any internally stored models or artifacts, is encrypted without requiring any configuration on your part. The service handles encryption transparently, so you do not need to enable a setting, upload a key, or manage any encryption infrastructure. On the AWS Certified AI Practitioner AIF-C01 exam, this concept tests your understanding of which AWS services offer built-in, default encryption versus those that require customer action. A common trap is assuming you must manually enable encryption or integrate AWS KMS, but for Comprehend, the default AES-256 is already active. Remember the memory tip: “Comprehend automatically comprehends encryption,” so you can focus on analysis, not setup.
AIF-C01 Practice Question: Security, Compliance and Governance for AI Solutions
This AIF-C01 practice question tests your understanding of security, compliance and governance for ai solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is using Amazon Comprehend to analyze customer feedback. They need to ensure that the documents are encrypted at rest. What should they do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
No action is needed; Amazon Comprehend automatically encrypts data at rest using AES-256
Amazon Comprehend automatically encrypts all data at rest using AES-256 encryption by default, with no additional configuration required. This encryption covers both the documents processed by the service and any models or artifacts stored internally. Therefore, no action is needed from the customer to enable encryption at rest.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

No action is needed; Amazon Comprehend automatically encrypts data at rest using AES-256
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume they need to manually enable encryption or use KMS, but Amazon Comprehend enforces encryption at rest automatically with no user action required, making 'No action needed' the correct answer.
Detailed technical explanation
How to think about this question
Amazon Comprehend uses server-side encryption with AES-256 for all data at rest, including input documents, output results, and any intermediate data stored in the service's internal data stores. This encryption is transparent to the user and cannot be disabled or customized; it is part of the service's security posture. In a real-world scenario, if a compliance audit requires customer-managed keys, Comprehend does not support KMS integration for at-rest encryption, so customers must rely on the default encryption or use client-side encryption before sending data.

Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
