DVA-C02 Development with AWS Services Practice Question
This DVA-C02 practice question tests your understanding of development with aws services. 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.
Consider the following CloudFormation template snippet:
Resources:
MyBucket:
Type: AWS::S3::Bucket
Properties:
BucketName: my-unique-bucket-12345
VersioningConfiguration:
Status: Enabled
MyLambdaFunction:
Type: AWS::Lambda::Function
Properties:
Handler: index.handler
Role: !GetAtt LambdaExecutionRole.Arn
Code:
S3Bucket: !Ref MyBucket
S3Key: function.zip
Runtime: nodejs18.x
A developer is reviewing a CloudFormation template that creates an S3 bucket and a Lambda function. The Lambda function's code is stored in the S3 bucket. What is a potential issue with this template?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Lambda function depends on the S3 bucket, but there is no DependsOn clause to ensure the bucket is created first.
Option B is correct because CloudFormation tries to create both resources in parallel, but the Lambda function needs the S3 bucket to exist first to retrieve the code. Additionally, the bucket must have the code uploaded before stack creation. Option A is wrong because the reference is valid. Option C is wrong because versioning is not required. Option D is wrong because the role reference is correct.
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 Lambda function's role is referenced incorrectly; it should be 'Ref' instead of 'GetAtt'.
Why it's wrong here
GetAtt is used to get the Arn attribute.
✓
The Lambda function depends on the S3 bucket, but there is no DependsOn clause to ensure the bucket is created first.
Why this is correct
CloudFormation may attempt to create the Lambda function before the bucket exists, causing failure.
Related concept
Read the scenario before looking for a memorised answer.
✗
The bucket name 'my-unique-bucket-12345' is not globally unique.
Why it's wrong here
The bucket name appears unique, but the main issue is dependency.
✗
The bucket must have versioning enabled to store Lambda code.
Why it's wrong here
Versioning is not required for storing Lambda code.
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 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.
