Amazon Web Services DVA-C02 Exam With Confidence Using Practice Dumps

Secrets Management: AWS Secrets Manager is designed specifically for storing and managing sensitive credentials.

Built-in Rotation: Secrets Manager provides automatic secret rotation functionality, enhancing security posture significantly.

IAM Integration: IAM policies and roles grant fine-grained access to ECS Fargate, ensuring the principle of least privilege.

Reduced Overhead: This solution centralizes secrets management and automates rotation, reducing operational overhead compared to the other options.

AWS CodeArtifact emits events when repository actions occur, such as publishing a new package. AWS documentation recommends Amazon EventBridge as the native service for routing AWS service events to targets with minimal configuration and no infrastructure to manage.

By creating an EventBridge rule that matches CodeArtifact package publication events and routing those events directly to an Amazon SNS topic , the developer can notify the team immediately. SNS provides built-in email subscriptions, retries, and delivery guarantees without custom code.

Option C is the most operationally efficient because it uses fully managed, serverless services and requires no custom compute, code maintenance, or orchestration. EventBridge directly supports SNS as a target, making the configuration straightforward.

Option A is invalid because CodeArtifact does not directly publish notifications to SNS topics. Options B and D introduce unnecessary complexity by adding Lambda or Step Functions and Amazon SES, increasing operational overhead without added value.

Therefore, using EventBridge to route CodeArtifact events to SNS is the AWS-recommended and simplest solution.

The correct answer is C. Use an AWS Lambda function that is invoked by an Amazon EventBridge scheduled event.

C. Use an AWS Lambda function that is invoked by an Amazon EventBridge scheduled event. This is correct. AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers. Lambda runs your code on a high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, and logging1. Amazon EventBridge is a serverless event bus service that enables you to connect your applications with data from a variety of sources2. EventBridge can create rules that run on a schedule, either at regular intervals or at specific times and dates, and invoke targets such as Lambda functions3. This solution meets the requirements of creating a small application that makes the same API call once each day at a designated time, without requiring any infrastructure in the AWS Cloud or any operational overhead.

A. Use a Kubernetes cron job that runs on Amazon Elastic Kubernetes Service (Amazon EKS). This is incorrect. Amazon EKS is a fully managed Kubernetes service that allows you to run containerized applications on AWS4. Kubernetes cron jobs are tasks that run periodically on a given schedule5. This solution could meet the functional requirements of creating a small application that makes the same API call once each day at a designated time, but it would not be the most operationally efficient manner. The company would need to provision and manage an EKS cluster, which would incur additional costs and complexity.

B. Use an Amazon Linux crontab scheduled job that runs on Amazon EC2. This is incorrect. Amazon EC2 is a web service that provides secure, resizable compute capacity in the cloud6. Crontab is a Linux utility that allows you to schedule commands or scripts to run automatically at a specified time or date7. This solution could meet the functional requirements of creating a small application that makes the same API call once each day at a designated time, but it would not be the most operationally efficient manner. The company would need to provision and manage an EC2 instance, which would incur additional costs and complexity.

D. Use an AWS Batch job that is submitted to an AWS Batch job queue. This is incorrect. AWS Batch enables you to run batch computing workloads on the AWS Cloud8. Batch jobs are units of work that can be submitted to job queues, where they are executed in parallel or sequentially on compute environments9. This solution could meet the functional requirements of creating a small application that makes the same API call once each day at a designated time, but it would not be the most operationally efficient manner. The company would need to configure and manage an AWS Batch environment, which would incur additional costs and complexity.
