This SSCP practice question tests your understanding of risk identification, monitoring and analysis. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Exposure of bucket contents to the public
The S3 bucket policy grants public access via a Principal of '*' and an Effect of 'Allow' for the 's3:GetObject' and 's3:ListBucket' actions. This means any unauthenticated user on the internet can list the objects in the bucket and read their contents, directly exposing the bucket contents to the public, making option D correct.
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.
✗
Unauthorized deletion of objects
Why it's wrong here
No delete actions are granted.
✗
Lack of encryption at rest
Why it's wrong here
The policy does not address encryption; it's a separate control.
✗
Inability to audit access
Why it's wrong here
CloudTrail can still log access; the policy doesn't prevent auditing.
✓
Exposure of bucket contents to the public
Why this is correct
The ListBucket action with Principal "*" allows anyone to enumerate objects.

Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the distinction between read access (GetObject) and list access (ListBucket). Here, the policy grants both, allowing public enumeration and reading. Candidates may mistakenly think only read is possible, but both actions are permitted, increasing the exposure risk.
Detailed technical explanation
How to think about this question
An S3 bucket policy with 'Principal': '*' and 'Action': 's3:GetObject' effectively makes the bucket publicly readable, which is a common misconfiguration leading to data breaches. AWS S3 evaluates bucket policies along with IAM policies and ACLs; a public bucket policy overrides any private ACL settings, so even if the bucket ACL is set to private, the policy grants anonymous access. Real-world incidents like the 2017 Verizon data leak occurred due to such overly permissive bucket policies.

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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
