DVA-C02 Deployment Practice Question

This DVA-C02 practice question tests your understanding of deployment. 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.

Refer to the exhibit. A CloudFormation template creates an S3 bucket with a 'Retain' deletion policy and an EC2 instance. If the stack is deleted, what happens to the S3 bucket?

A
The S3 bucket is deleted along with the stack.
Why wrong: 'Retain' prevents deletion.
B
The S3 bucket is moved to a different account.
Why wrong: No such behavior.
C
A snapshot of the S3 bucket is taken before deletion.
Why wrong: Snapshots are for EBS volumes, not S3.
D
The S3 bucket is retained and must be deleted manually.
The 'Retain' policy preserves the resource.

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 S3 bucket is retained and must be deleted manually.

Option D is correct because the 'Retain' deletion policy on the S3 bucket overrides the default stack deletion behavior. When a CloudFormation stack is deleted, any resource with a 'DeletionPolicy' set to 'Retain' is preserved in the AWS account, even though the resource is removed from the stack's template. The bucket continues to exist independently and must be manually deleted by the user via the AWS Management Console, CLI, or SDK.

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

The trap here is that candidates may assume all resources are automatically deleted when a stack is deleted, overlooking the 'DeletionPolicy' attribute that can override this default behavior for specific resources like S3 buckets.

Detailed technical explanation

How to think about this question

The 'DeletionPolicy' attribute in AWS CloudFormation can be set to 'Retain', 'Delete', or 'Snapshot' (for supported resources like RDS or EBS). For S3 buckets, only 'Retain' and 'Delete' are valid; 'Snapshot' is not supported. This policy is evaluated at stack deletion time, and if set to 'Retain', CloudFormation simply removes the logical resource from the stack template without calling the underlying API to delete the physical bucket. This is useful for preserving data that must outlive the stack, such as log archives or backup buckets.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
