- A
Configure caching in the SAM template using the CacheClusterEnabled property and use CloudFormation conditions to enable it only in the dev stage.
Using conditions is the most efficient approach. The SAM template can include a condition that evaluates to true for the dev stage, enabling caching.
- B
Create two separate SAM templates, one for dev with caching and one for prod without.
Why wrong: Maintaining two templates is more work and error-prone. The same template can handle both environments with conditions.
- C
Enable caching in the API Gateway console after each deployment for the dev stage.
Why wrong: Manual intervention is inefficient and not part of an automated CI/CD pipeline.
- D
Use a custom CloudFormation resource to toggle caching based on a parameter.
Why wrong: This adds unnecessary complexity. The built-in CacheClusterEnabled property with conditions achieves the goal more simply.
DVA-C02 Development with AWS Services Practice Question
This DVA-C02 practice question tests your understanding of development with aws services. 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.
A developer is building a serverless application using AWS SAM. The application includes an Amazon API Gateway endpoint with a Lambda function that processes user uploads. The developer wants to enable API caching in the development stage to speed up repeated requests, but disable caching in the production stage. What is the most efficient way to achieve this?
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
Configure caching in the SAM template using the CacheClusterEnabled property and use CloudFormation conditions to enable it only in the dev stage.
Option A is correct because AWS SAM extends AWS CloudFormation, allowing you to use CloudFormation conditions to conditionally enable the `CacheClusterEnabled` property on the `AWS::ApiGateway::Stage` resource. By defining a condition that evaluates to true only for the dev stage (e.g., based on a parameter like `StageName`), you can enable caching in dev and disable it in prod within a single SAM template, avoiding duplication and manual steps.
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 think caching must be configured per-deployment manually (Option C) or that separate templates are required (Option B), missing the power of CloudFormation conditions to conditionally enable features within a single SAM template.
Detailed technical explanation
How to think about this question
Under the hood, the `CacheClusterEnabled` property on an `AWS::ApiGateway::Stage` resource provisions a dedicated API Gateway cache cluster (e.g., 0.5GB to 237GB) that caches responses based on the stage's cache key settings. CloudFormation conditions evaluate at deploy time using intrinsic functions like `Fn::Equals` or `Fn::If`, allowing you to conditionally set properties without separate templates. A real-world scenario is a multi-environment pipeline where dev benefits from caching to reduce latency and costs, while prod avoids stale data or cache invalidation complexity.
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.
