QUESTION: 57

A company needs to harden its container images before the images are in a running state. The company's application uses Amazon Elastic Container Registry (Amazon ECR) as an image registry. Amazon Elastic Kubernetes Service (Amazon EKS) for compute, and an AWS CodePipeline pipeline that orchestrates a continuous integration and continuous delivery (CI/CD) workflow.
Dynamic application security testing occurs in the final stage of the pipeline after a new image is deployed to a development namespace in the EKS cluster. A developer needs to place an analysis stage before this deployment to analyze the container image earlier in the CI/CD pipeline.
Which solution will meet these requirements with the MOST operational efficiency?

Build the container image and run the docker scan command locally. Mitigate any findings before pushing changes to the source code repository. Write a pre-commit hook that enforces the use of this workflow before commit.
Create a new CodePipeline stage that occurs after the container image is built. Configure ECR basic image scanning to scan on image push. Use an AWS Lambda function as the action provider. Configure the Lambda function to check the scan results and to fail the pipeline if there are findings.
Create a new CodePipeline stage that occurs after source code has been retrieved from its repository. Run a security scanner on the latest revision of the source code. Fail the pipeline if there are findings.
Add an action to the deployment stage of the pipeline so that the action occurs before the deployment to the EKS cluster. Configure ECR basic image scanning to scan on image push. Use an AWS Lambda function as the action provider. Configure the Lambda function to check the scan results and to fail the pipeline if there are findings.

QUESTION: 58

A developer is testing a new file storage application that uses an Amazon CloudFront distribution to serve content from an Amazon S3 bucket. The distribution accesses the S3 bucket by using an origin access identity (OAI). The S3 bucket's permissions explicitly deny access to all other users.
The application prompts users to authenticate on a login page and then uses signed cookies to allow users to access their personal storage directories. The developer has configured the distribution to use its default cache behavior with restricted viewer access and has set the origin to point to the S3 bucket. However, when the developer tries to navigate to the login page, the developer receives a 403 Forbidden error.
The developer needs to implement a solution to allow unauthenticated access to the login page. The solution also must keep all private content secure.
Which solution will meet these requirements?

Add a second cache behavior to the distribution with the same origin as the default cache behavior. Set the path pattern for the second cache behavior to the path of the login page, and make viewer access unrestricted. Keep the default cache behavior's settings unchanged.
Add a second cache behavior to the distribution with the same origin as the default cache behavior. Set the path pattern for the second cache behavior to *, and make viewer access restricted. Change the default cache behavior's path pattern to the path of the login page, and make viewer access unrestricted.
Add a second origin as a failover origin to the default cache behavior. Point the failover origin to the S3 bucket. Set the path pattern for the primary origin to *, and make viewer access restricted. Set the path pattern for the failover origin to the path of the login page, and make viewer access unrestricted.
Add a bucket policy to the S3 bucket to allow read access. Set the resource on the policy to the Amazon Resource Name (ARN) of the login page object in the S3 bucket. Add a CloudFront function to the default cache behavior to redirect unauthorized requests to the login page's S3 URL.

QUESTION: 60

An ecommerce company is using an AWS Lambda function behind Amazon API Gateway as its application tier. To process orders during checkout, the application calls a POST API from the frontend. The POST API invokes the Lambda function asynchronously. In rare situations, the application has not processed orders. The Lambda application logs show no errors or failures.
What should a developer do to solve this problem?

Inspect the frontend logs for API failures. Call the POST API manually by using the requests from the log file.
Create and inspect the Lambda dead-letter queue. Troubleshoot the failed functions. Reprocess the events.
Inspect the Lambda logs in Amazon CloudWatch for possible errors. Fix the errors.
Make sure that caching is disabled for the POST API in API Gateway.

Amazon AWS Certified Developer - Associate DVA-C02: Skills Tested, Job Roles, and Study Tips

The AWS Certified Developer - Associate DVA-C02 certification is designed for individuals who perform a developer role and have one or more years of hands-on experience developing and maintaining applications on the Amazon Web Services platform. This certification validates a candidate's ability to demonstrate an in-depth understanding of core AWS services, uses, and basic AWS architecture best practices. Employers across various industries, from startups to large enterprises, seek professionals with this credential because it confirms the holder can write, deploy, and debug cloud-based applications using AWS. By achieving this certification, developers prove they possess the technical proficiency required to build secure and scalable cloud applications, which is a critical function in modern software engineering teams.

What the AWS Certified Developer - Associate DVA-C02 Exam Covers

The exam evaluates a candidate's proficiency across several critical domains, including development with AWS services, security, deployment, and troubleshooting and optimization. In practical terms, this means a developer must understand how to write code that interacts with AWS services like Amazon DynamoDB, Amazon SQS, and Amazon SNS, while also implementing appropriate security measures such as IAM policies and encryption. Deployment is a major focus, requiring knowledge of CI/CD pipelines, AWS Elastic Beanstalk, and AWS CloudFormation to automate the release of software. Troubleshooting and optimization require the ability to identify performance bottlenecks and resolve issues using tools like Amazon CloudWatch and AWS X-Ray. Our practice questions are structured to mirror these real-world scenarios, ensuring that candidates are tested on their ability to apply these concepts rather than just recalling definitions.

Among these domains, the development with AWS services and troubleshooting areas are often considered the most technically demanding by candidates. These sections require a deep understanding of how different services interact within an application architecture, often presenting complex scenarios where multiple services must be configured correctly to achieve a specific outcome. Candidates must demonstrate not only knowledge of individual service features but also the ability to diagnose why an application might be failing or underperforming in a cloud environment. This level of technical depth necessitates consistent practice, as the exam frequently tests the nuances of service limits, API calls, and integration patterns that are only mastered through hands-on experience.
