Configuration Management and IaC →hardMultiple SelectObjective-mapped

Quick Answer

The correct approach combines a Service Control Policy, an AWS Config managed rule with automatic remediation, and CloudFormation StackSets to enforce S3 bucket versioning and encryption across all accounts. An SCP acts as a preventive guardrail by denying the creation of any S3 bucket that lacks SSE-S3 encryption, while AWS Config continuously evaluates existing buckets for versioning compliance and triggers an SSM Automation runbook to remediate non-compliant resources automatically. CloudFormation StackSets then deploy a baseline template to every account, ensuring consistent infrastructure as code. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your ability to layer preventive and detective controls at scale—a common trap is choosing manual or pipeline-only solutions, which fail to enforce policies across new or existing resources. Remember the three-legged stool: SCP to prevent, Config to detect and fix, StackSets to deploy.

DOP-C02 Configuration Management and IaC Practice Question

This DOP-C02 practice question tests your understanding of configuration management and iac. 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 company manages multiple AWS accounts using AWS Organizations. The DevOps team needs to enforce that all newly created S3 buckets in any account automatically have versioning enabled and are encrypted with SSE-S3. Which THREE steps should the team take to achieve this using Infrastructure as Code and policy-based controls?

Full question →

A
Create an SCP that denies s3:PutObject if the bucket does not have encryption enabled.
SCPs can restrict API calls across accounts, enforcing encryption at creation time.
B
Configure AWS CodePipeline to run a script that checks bucket configurations after creation.
Why wrong: CodePipeline is for CI/CD pipelines, not for proactive enforcement.
C
Manually configure each new bucket via the AWS Management Console.
Why wrong: Manual configuration is error-prone and does not scale.
D
Use AWS CloudFormation StackSets to deploy a template that creates S3 buckets with required settings in all accounts.
StackSets enable consistent resource deployment across multiple accounts.
E
Deploy an AWS Config managed rule to check that S3 buckets have versioning enabled, with automatic remediation using SSM Automation.
Config rules detect non-compliance and can trigger remediation.

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

✓

Create an SCP that denies s3:PutObject if the bucket does not have encryption enabled.

Using a Service Control Policy (SCP) (A) prevents creation of buckets without encryption. AWS Config Rules (B) can remediate non-compliant buckets. CloudFormation StackSets (D) deploy a baseline template to all accounts. Option C (manual) is not scalable; E (CodePipeline only) does not enforce policies.

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 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.
