QUESTION: 1

A company is implementing an application on Amazon EC2 instances. The application needs to process incoming transactions. When the application detects a transaction that is not valid, the application must send a chat message to the company's support team. To send the message, the application needs to retrieve the access token to authenticate by using the chat API.
A developer needs to implement a solution to store the access token. The access token must be encrypted at rest and in transit. The access token must also be accessible from other AWS accounts.
Which solution will meet these requirements with the LEAST management overhead?

Use an AWS Systems Manager Parameter Store SecureString parameter that uses an AWS Key Management Service (AWS KMS) AWS managed key to store the access token. Add a resource-based policy to the parameter to allow access from other accounts. Update the IAM role of the EC2 instances with permissions to access Parameter Store. Retrieve the token from Parameter Store with the decrypt flag enabled. Use the decrypted access token to send the message to the chat.
Encrypt the access token by using an AWS Key Management Service (AWS KMS) customer managed key. Store the access token in an Amazon DynamoDB table. Update the IAM role of the EC2 instances with permissions to access DynamoDB and AWS KMS. Retrieve the token from DynamoDDecrypt the token by using AWS KMS on the EC2 instances. Use the decrypted access token to send the message to the chat.
Use AWS Secrets Manager with an AWS Key Management Service (AWS KMS) customer managed key to store the access token. Add a resource-based policy to the secret to allow access from other accounts. Update the IAM role of the EC2 instances with permissions to access Secrets Manager. Retrieve the token from Secrets Manager. Use the decrypted access token to send the message to the chat.
Encrypt the access token by using an AWS Key Management Service (AWS KMS) AWS managed key. Store the access token in an Amazon S3 bucket. Add a bucket policy to the S3 bucket to allow access from other accounts. Update the IAM role of the EC2 instances with permissions to access Amazon S3 and AWS KMS. Retrieve the token from the S3 bucket. Decrypt the token by using AWS KMS on the EC2 instances. Use the decrypted access token to send the massage to the chat.

QUESTION: 2

A company is running Amazon EC2 instances in multiple AWS accounts. A developer needs to implement an application that collects all the lifecycle events of the EC2 instances. The application needs to store the lifecycle events in a single Amazon Simple Queue Service (Amazon SQS) queue in the company's main AWS account for further processing.
Which solution will meet these requirements?

Configure Amazon EC2 to deliver the EC2 instance lifecycle events from all accounts to the Amazon EventBridge event bus of the main account. Add an EventBridge rule to the event bus of the main account that matches all EC2 instance lifecycle events. Add the SQS queue as a target of the rule.
Use the resource policies of the SQS queue in the main account to give each account permissions to write to that SQS queue. Add to the Amazon EventBridge event bus of each account an EventBridge rule that matches all EC2 instance lifecycle events. Add the SQS queue in the main account as a target of the rule.
Write an AWS Lambda function that scans through all EC2 instances in the company accounts to detect EC2 instance lifecycle changes. Configure the Lambda function to write a notification message to the SQS queue in the main account if the function detects an EC2 instance lifecycle change. Add an Amazon EventBridge scheduled rule that invokes the Lambda function every minute.
Configure the permissions on the main account event bus to receive events from all accounts. Create an Amazon EventBridge rule in each account to send all the EC2 instance lifecycle events to the main account event bus. Add an EventBridge rule to the main account event bus that matches all EC2 instance lifecycle events. Set the SQS queue as a target for the rule.

QUESTION: 3

An application is using Amazon Cognito user pools and identity pools for secure access. A developer wants to integrate the user-specific file upload and download features in the application with Amazon S3. The developer must ensure that the files are saved and retrieved in a secure manner and that users can access only their own files. The file sizes range from 3 KB to 300 MB.
Which option will meet these requirements with the HIGHEST level of security?

Use S3 Event Notifications to validate the file upload and download requests and update the user interface (UI).
Save the details of the uploaded files in a separate Amazon DynamoDB table. Filter the list of files in the user interface (UI) by comparing the current user ID with the user ID associated with the file in the table.
Use Amazon API Gateway and an AWS Lambda function to upload and download files. Validate each request in the Lambda function before performing the requested operation.
Use an IAM policy within the Amazon Cognito identity prefix to restrict users to use their own folders in Amazon S3.

QUESTION: 5

A developer has created an AWS Lambda function that is written in Python. The Lambda function reads data from objects in Amazon S3 and writes data to an Amazon DynamoDB table. The function is successfully invoked from an S3 event notification when an object is created. However, the function fails when it attempts to write to the DynamoDB table.
What is the MOST likely cause of this issue?

The Lambda function's concurrency limit has been exceeded.
DynamoDB table requires a global secondary index (GSI) to support writes.
The Lambda function does not have IAM permissions to write to DynamoDB.
The DynamoDB table is not running in the same Availability Zone as the Lambda function.

Amazon DVA-C01: Skills Tested, Job Roles, and Study Tips

The AWS Certified Developer - Associate DVA-C01 certification validates the technical expertise of professionals who design, develop, and maintain cloud-based applications on the Amazon Web Services platform. This certification is primarily intended for individuals in software developer or cloud engineer roles who possess at least one year of hands-on experience developing and maintaining applications on AWS. Employers across the technology sector value this credential because it demonstrates a candidate's ability to write code that optimizes the performance of AWS services and effectively integrates them into a cohesive architecture. By achieving this Amazon certification, professionals prove they can utilize software development kits and command-line interfaces to interact with cloud resources securely and efficiently. Organizations often require this validation to ensure their development teams can navigate the complexities of cloud-native application lifecycles without compromising system integrity.

What the DVA-C01 Exam Covers

The exam content focuses on four primary domains that reflect the daily responsibilities of a cloud developer. Candidates must demonstrate proficiency in Development with AWS Services, which involves writing code that interacts with services like Amazon DynamoDB, Amazon S3, and AWS Lambda. The Security domain tests your ability to implement identity and access management policies, encryption, and secure application configurations. Deployment strategies are equally critical, requiring knowledge of CI/CD pipelines, AWS Elastic Beanstalk, and AWS CloudFormation to automate the release process. Finally, Troubleshooting and Optimization requires candidates to analyze application performance, identify bottlenecks, and resolve issues using monitoring tools like Amazon CloudWatch. Our practice questions are designed to mirror these specific domains, ensuring that your study time is aligned with the actual requirements of the certification exam.

The Troubleshooting and Optimization domain is often cited as the most technically demanding section because it requires a deep understanding of how various services interact under load. Candidates must move beyond basic service knowledge to diagnose complex latency issues, memory leaks, or configuration errors that impact application availability. This section tests your ability to interpret logs, metrics, and traces to pinpoint the root cause of performance degradation in a distributed system. Success in this area requires a strong grasp of how to optimize code for cost and efficiency, which is a core competency for any developer working in a production cloud environment.
