- A
Enable automatic key rotation for the KMS key to ensure that even if the key is deleted, the data remains encrypted.
Why wrong: Key rotation does not prevent deletion.
- B
Add a statement to the KMS key policy that denies 'kms:ScheduleKeyDeletion' for all principals except the root user.
This prevents any IAM user or role from scheduling key deletion.
- C
Attach an IAM policy to the Redshift cluster role that denies 'kms:ScheduleKeyDeletion'.
Why wrong: The key policy controls access to the key; an IAM policy alone may not be sufficient if the key policy allows deletion.
- D
Set up a CloudTrail trail to monitor for 'ScheduleKeyDeletion' events and send an alert to the security team.
Why wrong: This detects deletion but does not prevent it.

DEA-C01 Data Security and Governance Practice Question
This DEA-C01 practice question tests your understanding of data security and governance. 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 gaming company uses Amazon Redshift for analytics. The Redshift cluster stores user data that must be encrypted at rest using a customer-managed KMS key. The company has enabled audit logging using AWS CloudTrail. The security team wants to ensure that any attempt to disable or delete the KMS key is immediately detected and triggers an automated response. They have set up a CloudWatch Events rule that triggers an SNS notification when the KMS key is scheduled for deletion. However, they also want to prevent the key from being deleted accidentally. What should they do?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"immediately / without restart"Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
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
✓
Add a statement to the KMS key policy that denies 'kms:ScheduleKeyDeletion' for all principals except the root user.
Option B is correct because adding a statement to the KMS key policy that denies 'kms:ScheduleKeyDeletion' for all principals except the root user explicitly prevents any user (including IAM users with full admin permissions) from scheduling deletion of the key. This is the most direct and authoritative control to prevent accidental deletion. Option A is incorrect because automatic key rotation does not prevent the key from being deleted; it only changes the backing key material. Option C is incorrect because an IAM policy attached to the Redshift cluster role does not affect permissions on the KMS key; the key policy is the authoritative control for actions on a customer-managed key. Option D is incorrect because CloudTrail monitoring only detects deletion events but does not prevent the deletion itself.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
