Quick Answer
The answer is AWS Config, as it is the best-suited service for checking S3 bucket versioning compliance across an entire AWS account. AWS Config provides a managed rule called s3-bucket-versioning-enabled that continuously evaluates each S3 bucket against the desired configuration state and reports noncompliant resources, making it ideal for automated compliance auditing. On the AWS Certified Security Specialty SCS-C02 exam, this question tests your ability to distinguish between monitoring services: CloudTrail logs API actions but does not assess configuration state, IAM Access Analyzer focuses on resource-based policy analysis, and Trusted Advisor offers limited checks that may not cover all buckets or provide granular compliance reporting. A common trap is confusing AWS Config with CloudTrail, but remember that Config evaluates the current state of resources, while CloudTrail records who did what. Memory tip: think of Config as the “compliance cop” that checks the rulebook, not the “camera” that records the action.
This SCS-C02 practice question tests your understanding of management and security 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 security engineer is tasked with ensuring that all S3 buckets in an AWS account have versioning enabled. The engineer needs to identify buckets that do not have versioning enabled. Which AWS service is BEST suited for this task?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
AWS Trusted Advisor
Why wrong: Trusted Advisor checks a limited set of best practices but may not include versioning for all buckets.
AWS CloudTrail
Why wrong: CloudTrail records API calls, not configuration state.
IAM Access Analyzer
Why wrong: Access Analyzer focuses on resource policies, not bucket features.
AWS Config
Config has managed rules to evaluate bucket versioning status.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS Config
AWS Config has a managed rule (s3-bucket-versioning-enabled) that can evaluate S3 buckets and report compliance. Option A (CloudTrail) logs API calls. Option B (IAM Access Analyzer) analyzes policies. Option C (Trusted Advisor) has limited checks and may not cover all buckets.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
