- A
{ 'Effect': 'Allow', 'Action': 'secretsmanager:UpdateSecret', 'Resource': '*' }
Why wrong: Resource is too broad.
- B
{ 'Effect': 'Allow', 'Action': 'secretsmanager:*', 'Resource': '*' }
Why wrong: This grants full access to all secrets.
- C
{ 'Effect': 'Allow', 'Action': 'secretsmanager:PutSecretValue', 'Resource': 'arn:aws:secretsmanager:us-east-1:123456789012:secret:*' }
Why wrong: Resource is too broad.
- D
{ 'Effect': 'Allow', 'Action': 'secretsmanager:PutSecretValue', 'Resource': 'arn:aws:secretsmanager:us-east-1:123456789012:secret:db_secrets-??????' }
This restricts to the specific secret and allows PutSecretValue.
DBS-C01 Database Security Practice Question
This DBS-C01 practice question tests your understanding of database security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A security team needs to grant an IAM user permission to modify only the 'db_secrets' secret in AWS Secrets Manager. Which IAM policy statement is correct?
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
{ 'Effect': 'Allow', 'Action': 'secretsmanager:PutSecretValue', 'Resource': 'arn:aws:secretsmanager:us-east-1:123456789012:secret:db_secrets-??????' }
Option D is correct because it grants the specific `secretsmanager:PutSecretValue` action on the exact ARN of the `db_secrets` secret, including the required six-character random suffix (`-??????`) that AWS Secrets Manager appends to secret names. This ensures the IAM user can only modify that single secret, meeting the security requirement of least privilege.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often forget the mandatory six-character random suffix in Secrets Manager ARNs and use only the secret name, leading them to choose a wildcard resource like option C, which grants unintended access to multiple secrets.
Detailed technical explanation
How to think about this question
AWS Secrets Manager automatically appends a six-character random string to the end of each secret name when creating the ARN (e.g., `db_secrets-abc123`). This suffix is required in IAM policy resource ARNs to uniquely identify a secret, as the name alone is not unique across deletions and recreations. Using `-??????` in the ARN pattern matches exactly that six-character suffix, ensuring the policy applies only to the intended secret instance.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
