The answer is to use an AWS Lambda function to copy images to a bucket in the desired region and invoke Rekognition there. This is correct because Amazon Rekognition processes images only in the AWS region where the API call is made, so by first copying the image data to an S3 bucket in the target region and then calling Rekognition from that same region, you guarantee that no image data ever leaves the specified geographic boundary. On the AWS Certified AI Practitioner AIF-C01 exam, this question tests your understanding of data residency controls and the fact that Rekognition does not automatically move data between regions—a common trap is assuming that S3 Cross-Region Replication alone satisfies residency, but that only copies the object without controlling where the Rekognition API call executes. Remember the memory tip: “Copy first, then call—keep the data local to the wall.”
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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 uses Amazon Rekognition to analyze images for a user-generated content platform. To comply with data residency requirements, they must ensure that images are not processed outside a specific AWS region. What should the company do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use an AWS Lambda function to copy images to a bucket in the desired region and invoke Rekognition there.
Option B is correct because it directly addresses the data residency requirement by using a Lambda function to copy images to an S3 bucket in the desired region and then invoking Rekognition in that same region. This ensures that image data never leaves the specified AWS region, as Rekognition processes images only in the region where the API call is made. The other options either do not prevent cross-region processing or are not applicable to Rekognition's data handling.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable Amazon Rekognition VPC endpoints.
Why it's wrong here
VPC endpoints are for private connectivity, not region restriction.
✓
Use an AWS Lambda function to copy images to a bucket in the desired region and invoke Rekognition there.
Why this is correct
This ensures data is processed only in the specified region.
Related concept
Read the scenario before looking for a memorised answer.
✗
Configure an AWS WAF rule to block cross-region processing.
Why it's wrong here
WAF does not control regional processing of Rekognition.
✗
Set up AWS Organizations to restrict the Rekognition service to one region.
Why it's wrong here
Organizations cannot restrict service usage to a single region.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse VPC endpoints or WAF with data residency controls, not realizing that Rekognition processes data in the region of the API call, and that network-level or application-layer controls do not enforce regional data processing boundaries.
Detailed technical explanation
How to think about this question
Amazon Rekognition processes images in the region where the API request is made, and the image data is not transferred across regions unless explicitly copied. By using a Lambda function to copy images to a bucket in the desired region and invoking Rekognition there, you guarantee that the image bytes are processed only in that region. This approach also avoids potential latency and cost issues from cross-region data transfer, and it aligns with data residency compliance by keeping data within jurisdictional boundaries.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
