DOP-C02 SDLC Automation Practice Question

This DOP-C02 practice question tests your understanding of sdlc automation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 team uses AWS CodeBuild to build a Node.js application. The buildspec.yml file is at the root of the repository. The build fails with 'Error: Cannot find module 'aws-sdk''. Which TWO actions could resolve the issue? (Choose TWO.)

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

Ensure 'aws-sdk' is listed in the 'dependencies' section of package.json.

Option A is correct because the 'aws-sdk' module must be declared in the 'dependencies' section of package.json for npm to install it during the build. Without this declaration, npm install will not download the module, causing the 'Cannot find module' error at runtime. Option D is correct because CodeBuild does not automatically run npm install; you must explicitly include an 'install' phase in buildspec.yml to execute 'npm install' and populate node_modules.

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.

  • Ensure 'aws-sdk' is listed in the 'dependencies' section of package.json.

    Why this is correct

    Without it, npm install will not install aws-sdk.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Specify a different Node.js runtime version in the buildspec.

    Why it's wrong here

    Runtime version does not affect module availability.

  • Add a 'pre_build' phase that runs 'npm test'.

    Why it's wrong here

    Testing does not install dependencies.

  • Add a 'install' phase that runs 'npm install'.

    Why this is correct

    Installs dependencies from package.json.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Add a 'build' phase command to compile the code.

    Why it's wrong here

    Compilation is not for installing modules.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates assume CodeBuild automatically runs 'npm install' or that the 'aws-sdk' is always available in the build environment, when in fact both the dependency declaration and explicit install phase are required.

Detailed technical explanation

How to think about this question

Under the hood, CodeBuild executes buildspec phases sequentially: 'install', 'pre_build', 'build', and 'post_build'. If no 'install' phase is defined, CodeBuild skips dependency installation entirely, leaving node_modules empty. The 'aws-sdk' module is a large dependency that must be explicitly listed in package.json; even if it were pre-installed in the CodeBuild environment, best practice is to declare it to ensure deterministic builds across environments.

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.

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 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.
