Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Identity and Access Management (IAM).
AWS Identity and Access Management (IAM) is the service used to manage access control for DynamoDB tables by creating policies that grant or deny permissions. Option A (CloudHSM) provides hardware security modules for encryption keys, not access control. Option B (KMS) manages encryption keys but does not handle access control. Option C (VPC security groups) control network traffic at the instance level, not database-level access control.
