DBS-C01 Database Security Practice Question
A security engineer is designing access controls for an Amazon DynamoDB table containing customer data. Which TWO actions enforce least privilege access?
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
✓
Use IAM conditions to restrict access to specific attributes.
Options A and C are correct. Using IAM conditions to restrict access to specific attributes (A) and implementing fine-grained access control using IAM policy conditions (C) both enforce least privilege by limiting the data and actions a user can access. Option B violates least privilege by granting all actions to all users. Option D is incorrect because Amazon DynamoDB does not support resource-based policies; access is controlled via identity-based IAM policies. Option E is incorrect because a VPC endpoint policy allowing all actions does not restrict access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use IAM conditions to restrict access to specific attributes.
Why this is correct
Correct: IAM conditions can restrict access to specific DynamoDB attributes, enforcing least privilege.
- ✗
Grant dynamodb:* action to all users.
Why it's wrong here
Incorrect: Granting dynamodb:* to all users violates least privilege.
- ✓
Implement fine-grained access control using IAM policy conditions.
Why this is correct
Correct: Fine-grained access control using IAM policy conditions is the standard approach for attribute-level security in DynamoDB.
- ✗
Use a resource-based policy on the DynamoDB table.
Why it's wrong here
Incorrect: DynamoDB does not support resource-based policies; identity-based IAM policies are used instead.
- ✗
Attach a VPC endpoint policy that allows all actions.
Why it's wrong here
Incorrect: A VPC endpoint policy that allows all actions does not enforce least privilege.
