Amazon AWS Certified Developer - Associate DVA-C02 Prüfungsfragen mit Lösungen (Q337-Q342):

337. Frage
A developer works on a public website. The developer wants to add monitoring to the website by using Amazon CloudWatch RUM. The developer needs to configure authentication that allows public access to send events to CloudWatch RUM. Which solutions will meet these requirements? (Choose two.)

A. Create an AWS IAM role that has permissions to send events to CloudWatch RUM. Create an Amazon Cognito identity pool that uses the IAM role for unauthenticated access. Configure CloudWatch RUM to use the identity pool.
B. Create a resource control policy (RCP) that allows unauthenticated access to send events to CloudWatch RUM.
C. Create an identity-based policy that has permissions to send events to CloudWatch RUM. Attach the policy to the CloudWatch RUM app monitor.
D. Create a resource-based policy for the CloudWatch RUM app monitor that allows unauthenticated access to send events to CloudWatch RUM.
E. Create an AWS IAM role that has permissions to send events to CloudWatch RUM. Configure the website to assume the IAM role before sending events.

Antwort: A,D

Begründung:
CloudWatch RUM supports public event ingestion in two built-in ways. You can attach a resource-based policy to the app monitor to allow unauthenticated clients to send events, or you can configure an Amazon Cognito identity pool that provides an unauthenticated IAM role for the website to use when sending data to RUM. AWS documentation for creating app monitors explicitly states that if you attach a resource-based policy, you do not need to sign requests with AWS credentials, and otherwise you can use a Cognito identity pool with an unauthenticated identity.

338. Frage
A developer built an application that calls an external API to obtain data, processes the data, and saves the result to Amazon S3. The developer built a container image with all of the necessary dependencies to run the application as a container.
The application runs locally and requires minimal CPU and RAM resources. The developer has created an Amazon ECS cluster. The developer needs to run the application hourly in Amazon ECS.
Which solution will meet these requirements with the LEAST amount of infrastructure management overhead?

A. Add an Amazon EC2 instance that runs the application.
B. Create an Amazon ECS cluster and add the managed node groups feature to run the application.
C. Define a task definition with an AWS Fargate launch type.
D. Add a capacity provider to manage instances.

Antwort: C

Begründung:
Requirement Summary:
* Containerized app
* Runshourly
* Minimal CPU and RAM
* Goal:Least infrastructure management
Evaluate Options:
A: Add a capacity provider to manage instances
* #Capacity providers are used for managingEC2-backed ECS clusters, which still requireunderlying EC2management.
B: Add an Amazon EC2 instance
* #Involvesmanaging infrastructure(provisioning, patching, scaling, etc.)
#C. Use AWS Fargate launch type
* #Serverless containerruntime
* #No server management
* #Easily scheduled usingEventBridge + ECS Fargate Task
* #Best fit for periodic workloadslike this
D: Use managed node groups
* #Applies toEKS (Kubernetes), not ECS
* Unnecessary overheadfor this use case
* Fargate:https://docs.aws.amazon.com/AmazonECS/latest/developerguide/what-is-fargate.html
* Scheduled ECS tasks: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/scheduled_tasks.

339. Frage
A company is running a custom application on a set of on-premises Linux servers that are accessed using Amazon API Gateway. AWS X-Ray tracing has been enabled on the API test stage.
How can a developer enable X-Ray tracing on the on-premises servers with the LEAST amount of configuration?

A. Install and run the X-Ray SDK on the on-premises servers to capture and relay the data to the X-Ray service.
B. Capture incoming requests on-premises and configure an AWS Lambda function to pull, process, and relay relevant data to X-Ray using the PutTelemetryRecords API call.
C. Install and run the X-Ray daemon on the on-premises servers to capture and relay the data to the X-Ray service.
D. Capture incoming requests on-premises and configure an AWS Lambda function to pull, process, and relay relevant data to X-Ray using the PutTraceSegments API call.

Antwort: C

Begründung:
The X-Ray daemon is a software that collects trace data from the X-Ray SDK and relays it to the X-Ray service. The X-Ray daemon can run on any platform that supports Go, including Linux, Windows, and macOS. The developer can install and run the X-Ray daemon on the on-premises servers to capture and relay the data to the X-Ray service with minimal configuration. The X-Ray SDK is used to instrument the application code, not to capture and relay data. The Lambda function solutions are more complex and require additional configuration.

340. Frage
A company runs an application on Amazon EC2 instances in an Auto Scaling group. The application experiences variable loads throughout each day.
The company needs to collect detailed metrics from the EC2 instances to right-size the instances.
The company also wants to monitor custom application metrics to ensure the application is performing efficiently.

B. Install the AWS SDK in the application's cade. Update the application to use the AWS SDK to collect and publish the EC2 instance metrics and the custom application metrics.
C. Configure AWS CloudTrail to capture and analyze the EC2 instance metrics and the custom application metrics.

Which solution will meet these requirements?

A. Store the video in the /tmp folder within the Lambda execution environment. Push a Lambda function URL to the customer.
