DOP-C02 Configuration Management and IaC Practice Question

This DOP-C02 practice question tests your understanding of configuration management and iac. 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 company uses AWS Elastic Beanstalk with a custom platform. They need to update the platform version to include a new security patch. Which approach should be used to create a new custom platform version?

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 a new platform version using the aws elasticbeanstalk create-platform-version command with an updated platform definition file.

Option D is correct because AWS Elastic Beanstalk custom platforms are defined using a platform definition file (a YAML or JSON file that specifies the AMI, Chef recipes, and other configuration). To create a new platform version with an updated security patch, you must update this platform definition file (e.g., to reference a new base AMI with the patch) and then run the `aws elasticbeanstalk create-platform-version` CLI command. This command packages the definition file and uploads it to Elastic Beanstalk, which then builds and registers the new platform version. The other options either bypass the custom platform framework or are not supported operations.

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.

  • ✗

    Use the Elastic Beanstalk CLI to rebuild the platform with the new AMI.

    Why it's wrong here

    The CLI does not rebuild platforms.

  • ✗

    Launch a new EC2 instance, apply the patch, and create an AMI, then update the platform version.

    Why it's wrong here

    You cannot update a platform version; you must create a new one.

  • ✗

    Modify the existing platform version's AMI ID using the Elastic Beanstalk console.

    Why it's wrong here

    Platform versions are immutable; you cannot modify them.

  • ✓

    Create a new platform version using the aws elasticbeanstalk create-platform-version command with an updated platform definition file.

    Why this is correct

    This creates a new custom platform version with the updated configuration.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates assume they can directly modify an existing platform version or use manual EC2 operations, but Elastic Beanstalk custom platforms require a formal versioning process through the platform definition file and the `create-platform-version` API.

Detailed technical explanation

How to think about this question

Under the hood, Elastic Beanstalk custom platforms use a Packer-based builder that reads the platform definition file to construct an AMI and then runs Chef recipes to configure the platform. The `create-platform-version` command triggers this build process in an AWS-managed environment, and the resulting platform version is assigned a unique version label. A real-world scenario is when a critical security patch (e.g., a kernel CVE) is released; you update the `ami_id` field in the platform definition file to point to a patched base AMI, then run the command to produce a new platform version without affecting existing 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.
