Full question →hardmultiple choiceObjective-mapped
A developer is storing an API secret for a third-party service in AWS Secrets Manager. The secret needs to be accessed by an AWS Lambda function that runs in a VPC. The Lambda function must have the minimum required permissions. Which IAM policy statement should the developer attach to the Lambda execution role?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
A policy that grants secretsmanager:GetSecretValue for the specific secret ARN and includes a condition for aws:SourceVpce to restrict access to the VPC endpoint
Correct. This provides least privilege and restricts access to requests coming through the VPC endpoint.
B
Distractor review
A policy that grants secretsmanager:GetSecretValue for all secrets in the account
This violates least privilege by granting access to all secrets.
C
Distractor review
A policy that grants secretsmanager:GetSecretValue for the secret and includes a condition for aws:SourceIp
The source IP for a Lambda function in a VPC is a private IP, which is not effective for restricting access via condition keys.
D
Distractor review
A policy that grants secretsmanager:GetSecretValue for the secret and includes a condition for ec2:Vpc
The ec2:Vpc condition key is not defined for Secrets Manager; the correct condition key for VPC endpoints is aws:SourceVpce.
Common exam trap
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.
Technical deep dive
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.

A developer is building a REST API using Amazon API Gateway that will serve static content from an Amazon S3 bucket. The API should cache responses for frequently accessed objects to reduce latency. Which API Gateway feature should the developer enable?
Question 2
A developer is running a web application on multiple Amazon EC2 instances behind an Application Load Balancer (ALB). The application needs to store user session state that must be available across all instances. The session data is small and temporary but must survive individual instance failures. Which AWS service should the developer use to store this session state?
Question 3
A developer has an AWS Lambda function that processes messages from an Amazon SQS standard queue. The function is idempotent and currently has a batch size of 10. The developer wants to increase throughput and increases the batch size to 100. After the change, CloudWatch metrics show a significant increase in throttles and the queue backlog is growing. The function's reserved concurrency is set to 10. What is the most effective action to resolve the throttling and improve throughput?
Question 4
A developer is managing an application running on Amazon EC2 instances behind an Application Load Balancer. Users report that the application becomes unresponsive after several hours, and restarting the instance temporarily fixes the issue. The developer suspects a memory leak but cannot add custom instrumentation. Which AWS service can collect memory utilization metrics and help identify the memory leak with minimal configuration?
Question 5
A developer is building a serverless web application using AWS Lambda and Amazon DynamoDB. The application needs to perform complex aggregations on data stored in DynamoDB. Which AWS service should the developer use to perform these aggregations efficiently without reading all the data into Lambda?
Question 6
A developer has an Amazon S3 bucket containing private user documents. The application must generate a time-limited URL for users to download their own documents without requiring the users to have AWS credentials. Which solution should the developer use?
FAQ
Questions learners often ask
What does this DVA-C02 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: A policy that grants secretsmanager:GetSecretValue for the specific secret ARN and includes a condition for aws:SourceVpce to restrict access to the VPC endpoint — To restrict access to the secret to only requests coming from within the VPC, the policy should include a condition using the VPC endpoint condition key (aws:SourceVpce). This ensures that only requests made through the specified VPC endpoint can retrieve the secret. Using aws:SourceIp is not appropriate because Lambda in a VPC uses private IP addresses. The ec2:Vpc condition key is not a standard AWS-wide condition. Granting access to all secrets is too broad.
