CCSP Cloud Platform and Infrastructure Security Practice Question
This CCSP practice question tests your understanding of cloud platform and infrastructure security. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company uses AWS Organizations with multiple accounts. A security team wants to ensure that a specific S3 bucket in the production account cannot be deleted by anyone, including the root user of that account. Which control should be implemented?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply a service control policy (SCP) to deny s3:DeleteBucket on the production account.
Option D is correct because a service control policy (SCP) is an AWS Organizations policy that can be applied to an account (or OU) to restrict permissions for all IAM users, roles, and even the root user of that account. By attaching an SCP that denies the s3:DeleteBucket action, the security team ensures that no principal in the production account, including the root user, can delete the specified S3 bucket. This provides a preventive control that overrides any allow permissions within the account.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 S3 event notifications to alert when a delete is attempted.
Why it's wrong here
Notifications are reactive, not preventive.
✗
Enable S3 Versioning on the bucket.
Why it's wrong here
Versioning preserves objects but does not prevent bucket deletion.
✗
Enable AWS CloudTrail to log any deletion attempt.
Why it's wrong here
Logging does not prevent deletion.
✓
Apply a service control policy (SCP) to deny s3:DeleteBucket on the production account.
Why this is correct
SCPs apply to all principals including root, and cannot be overridden within the account.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the distinction between preventive controls (like SCPs) and detective/reactive controls (like CloudTrail or notifications), and the trap here is that candidates confuse logging or versioning with actual deletion prevention.
Detailed technical explanation
How to think about this question
SCPs are evaluated before any IAM or resource-based policies, and they use a deny-by-default model where an explicit deny in an SCP overrides any allow. Under the hood, SCPs are applied at the organization level and propagate to all accounts in the OU, effectively creating a guardrail that even the root user cannot bypass. A real-world scenario is a multi-account environment where a centralized security team must enforce immutable infrastructure, such as preventing deletion of critical logging or backup buckets across all accounts.

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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
