Hi jgofaws,
Thank you for your valuable feedback. We understand your concern regarding the statement, “sensitive information is anonymized prior to landing in a NoSQL database,” and how it might make Option 1 seem valid since Amazon S3 is not a NoSQL database, and data is anonymized before reaching Amazon DynamoDB. After reviewing your query, we agree that the wording could be more precise, which might cause confusion.
The intent of the original question was to ensure that no unanonymized PII is stored in any system, including S3, before it is anonymized. In Option 1, PII is stored in S3 before the anonymization process in Lambda, which does not meet this goal. To improve clarity, we will update the statement to: “sensitive information is anonymized prior to landing in any storage system before being stored in a NoSQL database.” We will also revise the explanation to better clarify why Option 1 is incorrect due to storing PII in S3 first.
We appreciate your input and are committed to providing clear and accurate questions. The updated version will be reflected soon. If you have further questions, feel free to reach out!
Best regards,
Irene @ Tutorials Dojo
