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.

Exhibit

Refer to the exhibit.
```
{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Parameters": {
    "Environment": {
      "Type": "String",
      "AllowedValues": ["dev", "prod"]
    }
  },
  "Conditions": {
    "IsProd": {"Fn::Equals": [{"Ref": "Environment"}, "prod"]}
  },
  "Resources": {
    "MyBucket": {
      "Type": "AWS::S3::Bucket",
      "DeletionPolicy": {"Fn::If": ["IsProd", "Retain", "Delete"]}
    }
  }
}
```

A CloudFormation stack is created with the template above and the parameter Environment set to 'dev'. Later, the stack is deleted. What happens to the S3 bucket?

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

✓

The bucket is deleted.

Option C is correct. By default, CloudFormation uses a `DeletionPolicy` of `Delete` for S3 buckets. When the stack is deleted, CloudFormation attempts to delete the bucket. If the bucket is empty, the deletion succeeds. If the bucket contains objects, the deletion fails and the bucket is retained. The question does not specify that the bucket contains objects, so the correct answer is that the bucket is deleted. The template is not provided, but assuming no custom `DeletionPolicy` is set, this default behavior applies.

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.

  • ✗

    The bucket is retained only if it contains objects.

    Why it's wrong here

    DeletionPolicy does not depend on content.

  • ✗

    The bucket is retained.

    Why it's wrong here

    DeletionPolicy is Delete for dev.

  • ✓

    The bucket is deleted.

    Why this is correct

    DeletionPolicy evaluates to Delete.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    The bucket is deleted but the objects are retained.

    Why it's wrong here

    Bucket is deleted with objects.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap is that candidates may think CloudFormation automatically handles object deletion for non-empty buckets, or that the default action is to retain the bucket. In reality, the default `DeletionPolicy` is `Delete`, which only works if the bucket is empty. If the bucket contains objects, the delete operation fails, causing the stack deletion to fail as well.

Detailed technical explanation

How to think about this question

Under the hood, CloudFormation uses the S3 API `DeleteBucket` which fails if the bucket is not empty. If the bucket contains objects, the stack deletion will fail and roll back, leaving the bucket intact. This behavior is controlled by the `DeletionPolicy` attribute: `Delete` (default) attempts deletion, `Retain` preserves the bucket, and `Snapshot` (for supported resources) creates a snapshot before deletion. In real-world scenarios, forgetting to set `DeletionPolicy: Retain` for critical data buckets can lead to accidental data loss during stack teardowns.

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 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.
