This CRISC practice question tests your understanding of it risk identification. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Unrestricted public read access to confidential data
The policy statement 'All S3 buckets must be private by default' directly addresses the risk of public read access to confidential data. If a bucket is misconfigured as public, anyone on the internet can read its objects without authentication, leading to a data breach. This is the primary risk because the policy explicitly targets preventing unauthorized public exposure.
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 may confuse the primary risk (public read access to data) with secondary risks like logging or encryption, but the policy's explicit focus on 'private by default' directly targets unauthorized public exposure.

Detailed technical explanation
How to think about this question
S3 bucket policies and ACLs control access; a public bucket has a policy like `{"Effect":"Allow","Principal":"*","Action":"s3:GetObject","Resource":"arn:aws:s3:::bucket/*"}`. Even if the bucket is private by default, a misconfigured bucket policy or ACL can override this, allowing anonymous read access. In a real-world scenario, a developer might accidentally set a bucket ACL to 'public-read' during testing, exposing sensitive customer data.

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 practitioner preparing for the CRISC exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
