Amazon AWS Certified Developer - Associate Sample Questions (Q47-Q52):

NEW QUESTION # 47
A developer is using an AWS account to build an application that stores files in an Amazon S3 bucket. Files must be encrypted at rest by AWS KMS keys. A second AWS account must have access to read files from the bucket.
The developer wants to minimize operational overhead for the application.
Which combination of solutions will meet these requirements? (Select TWO.)

A. Create a gateway endpoint for the S3 bucket. Modify the endpoint policy to grant s3:GetObject permissions to the second AWS account.
B. Use a customer managed key to encrypt the files. Create a key policy that grants kms: Decrypt permissions to the second AWS account.
C. Use an AWS managed key to encrypt the files. Create a key policy that grants kms:Decrypt permissions to the second AWS account.
D. Create a service control policy (SCP) that grants s3:GetObject permissions to the second AWS account.
E. Create a bucket policy for the S3 bucket that grants s3:GetObject permissions to the second AWS account.

Answer: B,E

Explanation:
Step-by-Step Breakdown:
Requirement Summary:
* Encrypt S3 objects usingKMS keys
* Cross-account read accessto another AWS account
* Minimize operational overhead
Option A: Use a customer managed key + key policy granting kms:Decrypt to second account
* #Correct: Customer managed keys allow full control ofkey policy.
* You can add a statement to allowcross-account accessusing the second account's IAM principal.
Option B: Use AWS managed key + key policy granting access to second account
* #Incorrect: AWS-managed KMS keys (aws/s3)cannot be modifiedto add cross-account access in key policies.
Option C: SCP that grants s3:GetObject to second account
* #Incorrect: SCPs are used torestrict or allow permissions across AWS Organizations, not togrant S3 or KMS accessdirectly.
Option D: Create a bucket policy granting s3:GetObject to second account
* #Correct: Bucket policies can grantcross-account accessto specific IAM users or roles in the second account.
Option E: Gateway endpoint for S3 with cross-account access
* #Incorrect: Gateway endpoints only applywithin the same VPC/account. Cross-account use with endpoint policies is not the correct pattern for this use case.
* Cross-account S3 access with KMS:https://docs.aws.amazon.com/AmazonS3/latest/userguide/example- walkthroughs-managing-access-example2.html
