DOP-C02 SDLC Automation Practice Question

This DOP-C02 practice question tests your understanding of sdlc automation. 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.

A DevOps team is designing a CI/CD pipeline for a microservices application. Each microservice has its own CodeCommit repository and must be built and deployed independently. The team wants to minimize manual configuration and ensure that adding a new microservice automatically creates the corresponding pipeline stages. Which approach should the team use?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.

Full question →

A
Create a separate AWS CodePipeline for each microservice manually using the AWS Management Console.
Why wrong: Manual creation is not scalable.
B
Use the AWS Cloud Development Kit (CDK) to define a pipeline that dynamically discovers repositories.
Why wrong: CDK can be used but does not automatically discover new repos without custom code.
C
Use a single AWS CodePipeline with multiple stages, each triggered by a different branch of the same repository.
Why wrong: This would require all microservices in one repo, contradicting independent repos.
D
Define a CloudFormation template that creates a pipeline for a given repository and invoke it automatically when a new repository is created using EventBridge and Lambda.
This approach automates pipeline creation via event-driven infrastructure as code.

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

✓

Define a CloudFormation template that creates a pipeline for a given repository and invoke it automatically when a new repository is created using EventBridge and Lambda.

Option D is correct because AWS CloudFormation can define the pipeline infrastructure as code, and using nested stacks or a template that parameterizes the repository name allows for easy replication. Option A is wrong because manually updating a single pipeline is error-prone and not scalable. Option B is wrong because creating separate pipelines manually defeats automation. Option C is wrong because the AWS CDK can define infrastructure but requires separate stacks per service unless using loops or constructs.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.

What to study next

Got this wrong? Here's your next step.

Identify which DOP-C02 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
