Amazon AWS Certified Developer - Associate Sample Questions (Q651-Q656):

NEW QUESTION # 651
A developer is creating an application that includes an Amazon API Gateway REST API in the us-east-2 Region. The developer wants to use Amazon CloudFront and a custom domain name for the API. The developer has acquired an SSL/TLS certificate for the domain from a third-party provider.
How should the developer configure the custom domain for the application?

A. Import the SSL/TLS certificate into CloudFront. Create a DNS CNAME record for the custom domain.
B. Import the SSL/TLS certificate into AWS Certificate Manager (ACM) in the us-east-1 Region. Create a DNS CNAME record for the custom domain.
C. Import the SSL/TLS certificate into AWS Certificate Manager (ACM) in the same Region as the API. Create a DNS A record for the custom domain.
D. Import the SSL/TLS certificate into AWS Certificate Manager (ACM) in the same Region as the API. Create a DNS CNAME record for the custom domain.

Answer: A

NEW QUESTION # 652
A developer creates a consumer budgeting application on AWS. The developer wants to release new application features into a beta environment. The developer wants to monitor deployments in the beta environment and the production environment. The developer must have the ability to automatically roll back a deployment in response to performance alarms.
Which solution will meet these requirements with the LEAST operational overhead?

A. Use AWS AppConfig to create beta and production environments. Specify the appropriate environment ID in the application for each deployment. Configure Amazon CloudWatch alarms for each environment.
B. Create one Amazon ECS cluster for each environment. Configure AWS X-Ray to shift traffic in response to errors in the environments.
C. Create one AWS Lambda alias that points to a beta version of the application and a second alias that points to a production version of the application. Instrument the application by using AWS X-Ray.
D. Use AWS Elastic Beanstalk to create the beta and production environments. Create two A records in Amazon Route 53 that point to the environment domain endpoints. Configure Amazon CloudWatch alarms for each environment.

Answer: A

Explanation:
AWS AppConfig is the correct choice because it is built specifically for controlled application configuration and feature deployments across environments such as beta and production. AWS AppConfig supports feature flags and dynamic configurations, which allow developers to release application behavior changes without redeploying the full application. More importantly, AppConfig deployments can be monitored with Amazon CloudWatch alarms and can automatically roll back when an alarm is triggered. That directly matches the requirement to monitor both beta and production deployments and automatically roll back in response to performance alarms. ECS clusters, Elastic Beanstalk environments, and Lambda aliases can support deployment patterns, but they add more infrastructure or application-specific complexity. AWS AppConfig provides the least operational overhead for feature release control, monitoring, and rollback.

NEW QUESTION # 653
A company has an AWS Lambda function that processes incoming requests from an Amazon API Gateway API. The API calls the Lambda function by using a Lambda alias. A developer updated the Lambda function code to handle more details related to the incoming requests. The developer wants to deploy the new Lambda function for more testing by other developers with no impact to customers that use the API.
Which solution will meet these requirements with the LEAST operational overhead?

A. Create a new version of the Lambda function. Create and deploy a second Lambda function to filter incoming requests from API Gateway. If the filtering Lambda function detects a test request, the filtering Lambda function will invoke the new Lambda version of the code. For other requests, the filtering Lambda function will invoke the old Lambda version. Update the API Gateway API to use the filtering Lambda function.
B. Create a new version of the Lambda function. Create a new API Gateway API for testing purposes. Update the integration of the new API with the new Lambda version. Use the new API for testing.
C. Create a new version of the Lambda function. Create a new stage on API Gateway with integration to the new Lambda version. Use the new API Gateway stage to test the Lambda function.
D. Update the existing Lambda alias used by API Gateway to a weighted alias. Add the new Lambda version as an additional Lambda function with a weight of 10%. Use the existing API Gateway stage for testing.

Answer: C

NEW QUESTION # 654
A company has a large amount of data in an Amazon DynamoDB table. A large batch of data is appended to the table once each day. The company wants a solution that will make all the existing and future data in DynamoDB available for analytics on a long-term basis.
Which solution meets these requirements with the LEAST operational overhead?

A. Configure Amazon EMR to copy DynamoDB data to Amazon S3.
B. Configure DynamoDB incremental exports to Amazon S3.
C. Configure Amazon EMR to copy DynamoDB data to Hadoop Distributed File System (HDFS).
D. Configure Amazon DynamoDB Streams to write records to Amazon S3.

Answer: B

Explanation:
Comprehensive Detailed Explanation with all AWS Reference
Why Option A is Correct:
DynamoDB supports incremental exports to Amazon S3 natively, making data analytics-ready with minimal operational overhead.
Why Other Options are Incorrect:
Option B: DynamoDB Streams require additional processing logic to write to S3, increasing complexity.
Option C & D: Using EMR for data movement adds unnecessary operational overhead compared to native exports.
AWS Documentation Reference:
DynamoDB Exports to S3

NEW QUESTION # 655
A developer is using an AWS CloudFormation template to create a pipeline in AWS CodePipeline. The template creates an Amazon S3 bucket that the pipeline references in a source stage. The template also creates an AWS CodeBuild project for a build stage. The pipeline sends notifications to an Amazon SNS topic. Logs for the CodeBuild project are stored in Amazon CloudWatch Logs.
The company needs to ensure that the pipeline's artifacts are encrypted with an existing customer-managed AWS KMS key. The developer has granted the pipeline permissions to use the KMS key.
Which additional step will meet these requirements?

A. Create an Amazon S3 gateway endpoint that the pipeline can access.
B. Configure the notification topic to use the existing KMS key to enable encryption with the existing KMS key.
C. In the CloudFormation template, use the KMS key to encrypt the logs in CloudWatch Logs.
D. Apply an S3 bucket policy that ensures the pipeline sends only encrypted objects to the S3 bucket.

Answer: D

Explanation:
* Why Option C is Correct:Ensuring that pipeline artifacts are encrypted with a customer-managed AWS KMS key involves configuring the S3 bucket policy to require encryption. This policy ensures all objects uploaded to the bucket are encrypted with the specified KMS key.
* Why Other Options are Incorrect:
* Option A: A gateway endpoint improves S3 access efficiency but does not enforce encryption.
* Option B: Encrypting CloudWatch Logs is unrelated to securing pipeline artifacts.
* Option D: Configuring SNS for encryption does not affect the artifacts stored in the S3 bucket.
* AWS Documentation References:
* Using Server-Side Encryption with S3 Bucket Policies
