What should the developer do so that the company can meet the PII requirements while maintaining only one copy of the document?
Set up an S3 event notification that invokes the removePii function when an S3 GET request is made. Call Amazon S3 by using a GET request to access the object without PII.
Set up an S3 event notification that invokes the removePii function when an S3 PUT request is made. Call Amazon S3 by using a PUT request to access the object without PII.
Create an S3 Object Lambda access point from the S3 console. Select the removePii function. Use S3 Access Points to access the object without PII.
Create an S3 access point from the S3 console. Use the access point name to call the GetObjectLegalHold S3 API function. Pass in the removePii function name to access the object without PII.
Explanations:
S3 event notifications can trigger Lambda functions only for PUT, POST, COPY, or DELETE events, not for GET requests. This setup does not satisfy the requirement to modify the document on retrieval.
Triggering the Lambda function on a PUT request would modify the original document in S3, which conflicts with the requirement to maintain a single original, immutable document.
S3 Object Lambda access points allow for modifying object data on retrieval. By configuring the removePii function with an Object Lambda access point, PII can be removed on demand based on access context, without creating multiple copies of the document.
The GetObjectLegalHold API function does not support invoking a Lambda function or modifying the retrieved object, so it does not meet the requirement to return a version without PII.
I arrange that the answer is:
Create an S3 Object Lambda access point from the S3 console. Select the removePii function. Use S3 Access Points to access the object without PII.
In my experience, the answer is:
Create an S3 Object Lambda access point from the S3 console. Select the removePii function. Use S3 Access Points to access the object without PII.
