The correct answer is that the DynamoDBReadPolicy template grants read access to a DynamoDB table, and SAM policy templates are managed policies that can be applied in the Globals section. These templates simplify attaching AWS managed IAM policies to Lambda functions by abstracting common permission sets—like DynamoDBReadPolicy for read actions—so you don’t have to write raw IAM documents. On the AWS Certified Developer Associate DVA-C02 exam, this concept tests your ability to configure minimal permissions in a serverless application using AWS SAM policy templates, often appearing in scenario-based questions where you must choose the correct template for a given resource. A common trap is assuming policy templates support custom resources or fine-grained resource-level permissions, but they are designed only for predefined, common use cases like DynamoDB read or write access. Memory tip: think “SAM templates = shortcut for common IAM policies, not custom or granular.”
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.
A developer is deploying a serverless application using AWS SAM. The application includes an Amazon DynamoDB table and a Lambda function that reads from the table. The developer wants to ensure that the Lambda function has the minimum required permissions to read from the table. Which THREE statements about SAM policy templates are correct? (Choose THREE.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SAM policy templates are AWS-managed policies that can be applied to Lambda function roles
Options A, D, and E are correct. SAM policy templates provide managed policies, can be used in the Globals section, and DynamoDBReadPolicy grants read access. Option B is incorrect because policy templates do not support custom resources. Option C is incorrect because templates are for common use cases, not fine-grained resource-level permissions.
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
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
