All DVA-C02 questions

DVA-C02 Question 1

Select 3

You are developing a serverless web application on AWS that allows users to upload images. The application requires the following:

  1. The uploaded images should be stored securely.
  2. The application should trigger image processing as soon as an image is uploaded.
  3. Processed images should be stored in another location for retrieval.

Which combination of AWS services and features should you use to meet these requirements?

  1. A

    Amazon S3 with S3 Event Notifications to trigger an AWS Lambda function for image processing

  2. B

    Amazon DynamoDB to store the uploaded images and use DynamoDB Streams to trigger image processing

  3. C

    AWS Lambda to process the uploaded images and store the processed images in another S3 bucket

  4. D

    Amazon SQS to handle image processing requests and Amazon RDS to store the images

  5. E

    Amazon S3 with versioning enabled for secure storage of both uploaded and processed images

Show answer and explanation

Correct answers: A, C, E

Explanation

To meet the requirements, Amazon S3 is used to securely store uploaded images. S3 Event Notifications can automatically trigger an AWS Lambda function for image processing. The Lambda function processes the image and stores the processed version in another S3 bucket. Enabling S3 versioning ensures secure storage and prevents accidental overwrites or deletions. This combination of services ensures a serverless, scalable, and secure architecture.

  • A. Correct.

    Amazon S3 with S3 Event Notifications allows you to trigger an AWS Lambda function when an object is uploaded to a bucket, which is suitable for this use case.

  • B. Incorrect.

    Amazon DynamoDB is not suitable for storing images because it is a NoSQL database designed for structured data, not binary files such as images.

  • C. Correct.

    AWS Lambda can be used to process the images (e.g., resizing or applying filters) and store the processed images in another S3 bucket.

  • D. Incorrect.

    Amazon SQS and Amazon RDS are not ideal for this use case. SQS is primarily for decoupling components, and RDS is a relational database, not designed to store images.

  • E. Correct.

    Amazon S3 with versioning enabled enhances the security and durability of stored images by keeping multiple versions of objects, ensuring data is not lost.

DVA-C02 Question 2

Single answer

You are developing a serverless application that processes images uploaded to an S3 bucket. When a new image is uploaded, metadata about the image needs to be stored in a DynamoDB table. The solution should scale automatically and ensure that no images are missed. Which of the following is the most appropriate architecture for this requirement?

  1. A

    Set up an Amazon S3 event notification to trigger an AWS Lambda function that processes the image metadata and stores it in DynamoDB.

  2. B

    Use Amazon S3 Transfer Acceleration to send image metadata directly to DynamoDB.

  3. C

    Set up an Amazon S3 event notification to send the image metadata to an Amazon SQS queue, and then create an EC2 instance to process the metadata and store it in DynamoDB.

  4. D

    Create a CloudWatch Events rule to monitor the S3 bucket for new image uploads and trigger a Lambda function to process and store the metadata in DynamoDB.

Show answer and explanation

Correct answer: A

Explanation

The most appropriate solution leverages S3 event notifications to directly trigger an AWS Lambda function. This architecture is serverless, scalable, and simplifies the processing of image metadata. Lambda integrates seamlessly with both S3 and DynamoDB, making it the ideal choice for this requirement.

  • A. Correct.

    This is the correct option. S3 event notifications can directly trigger a Lambda function, which is well-suited for serverless event-driven architectures. The Lambda function can process the image metadata and store it in DynamoDB, ensuring scalability and reliability.

  • B. Incorrect.

    This is incorrect. Amazon S3 Transfer Acceleration is used to accelerate data transfers to S3, not to process or transfer metadata to DynamoDB.

  • C. Incorrect.

    This is incorrect. While SQS could be used as an intermediary, setting up an EC2 instance to process the metadata is not a cost-effective or scalable solution compared to a serverless approach using Lambda.

  • D. Incorrect.

    This is incorrect. CloudWatch Events is not designed to monitor S3 bucket events for object uploads. S3 event notifications are the correct mechanism for this use case.

DVA-C02 Question 3

Single answer

You are developing a serverless web application using AWS Lambda, Amazon API Gateway, and Amazon DynamoDB. The application requires secure, temporary access to write data to the DynamoDB table from the Lambda function. How should you configure this access?

  1. A

    Attach an inline policy with write permissions to the Lambda function's execution role.

  2. B

    Hardcode AWS credentials as environment variables in the Lambda function.

  3. C

    Create an IAM user with write permissions to DynamoDB and use its access keys in the Lambda function.

  4. D

    Grant write permissions to the DynamoDB table for all users in the account.

Show answer and explanation

Correct answer: A

Explanation

The best practice for granting access to AWS services, such as DynamoDB, from a Lambda function is to use the Lambda function's execution role. You can attach an inline policy to the execution role with the necessary permissions, such as the write permissions required in this scenario. This approach ensures that temporary credentials are securely and automatically provided to the Lambda function, adhering to the principle of least privilege.

  • A. Correct.

    Correct. Attaching an inline policy with write permissions to the Lambda function's execution role ensures secure, temporary access to the DynamoDB table. This is the recommended practice for assigning permissions in AWS serverless architectures.

  • B. Incorrect.

    Incorrect. Hardcoding AWS credentials in the Lambda function's environment variables is a security risk and violates best practices. AWS credentials should never be hardcoded.

  • C. Incorrect.

    Incorrect. Creating an IAM user and using its access keys in the Lambda function is not a secure or scalable solution, and it doesn't leverage temporary credentials provided by the execution role.

  • D. Incorrect.

    Incorrect. Granting write permissions to all users in the account creates a security vulnerability by over-provisioning access to the DynamoDB table.

Study tips

Hands-On Practice

  • Build at least 3-5 complete applications using multiple AWS services
  • Use AWS Free Tier extensively - theoretical knowledge alone is insufficient
  • Practice with AWS CLI and at least one SDK (Python boto3, JavaScript, or Java)
  • Deploy sample applications using different deployment methods (CloudFormation, SAM, Elastic Beanstalk)
  • Break things intentionally and practice troubleshooting with CloudWatch and X-Ray

Service-Specific Focus

  • Lambda: Master all invocation models (synchronous, asynchronous, stream-based), environment variables, layers, and versions
  • DynamoDB: Practice queries vs scans, GSI vs LSI, capacity modes, and streams
  • API Gateway: Understand integration types, stages, canary deployments, and caching
  • IAM: Write policies from scratch, understand policy evaluation logic and boundaries
  • CodePipeline: Build complete CI/CD pipelines including build, test, and deploy stages

Exam-Specific Strategies

  • The exam emphasizes serverless architectures - expect 40% of questions on Lambda, API Gateway, and related services
  • Understand the 'AWS Way' - know when AWS recommends managed services over self-managed solutions
  • Learn to eliminate obviously wrong answers first - usually 2 choices can be quickly eliminated
  • Time management: 2 minutes per question average, flag difficult questions and return later
  • Watch for trick questions about service limits, pricing models, and regional availability

Common Pitfalls to Avoid

  • Don't confuse CloudWatch Logs with CloudTrail - know which service tracks what
  • Understand the difference between SQS standard vs FIFO queues and when to use each
  • Know Lambda limitations: 15-minute timeout, 10GB memory max, /tmp storage limits
  • Remember that S3 is eventually consistent for overwrite PUTS and DELETES in certain scenarios
  • Don't overlook Step Functions - it appears more frequently in DVA-C02 than previous versions

Practice Test Strategy

  • Take your first practice test after week 6 to identify weak areas
  • Complete at least 4-5 full-length practice exams before the actual test
  • Review every incorrect answer thoroughly, understanding why it's wrong
  • Take practice tests under timed conditions to build exam stamina
  • Aim for consistent 85%+ scores on practice tests before scheduling the exam

Documentation Deep Dives

  • Read the Developer Guide (not just API reference) for Lambda, DynamoDB, and API Gateway
  • Study AWS SDK error handling patterns and retry strategies
  • Review CloudFormation resource properties for commonly used services
  • Understand CloudWatch Logs Insights query syntax and common query patterns
  • Memorize important service quotas and limits that affect application design

Exam day checklist

  • Arrive 30 minutes early if testing at a center, or start your system check 30 minutes before for online proctoring
  • Read each question carefully - AWS often includes extra information as distractors
  • Use the 'Mark for Review' feature liberally - don't get stuck on difficult questions
  • Watch for keywords: 'most cost-effective', 'least operational overhead', 'most secure', 'highest performance'
  • If two answers seem correct, choose the one that's more 'serverless' or 'managed' - AWS prefers these approaches
  • Remember that Lambda cold starts, DynamoDB capacity modes, and IAM policy evaluation are frequently tested
  • For scenario-based questions, identify the main requirement first, then eliminate solutions that don't meet it
  • Budget your time: aim to complete first pass through all questions with 30-40 minutes remaining for review
  • Don't second-guess yourself too much - your first instinct is often correct if you've studied thoroughly
  • Stay calm and confident - the exam tests practical knowledge, and if you've built real applications, you'll recognize scenarios
