Amazon AWS Certified Developer - Associate Sample Questions (Q309-Q314):

NEW QUESTION # 309
A developer has a legacy application that is hosted on-premises. Other applications hosted on AWS depend on the on-premises application for proper functioning. In case of any application errors, the developer wants to be able to use Amazon CloudWatch to monitor and troubleshoot all applications from one place.
How can the developer accomplish this?

  • A. Upload log files from the on-premises server to Amazon S3 and have CloudWatch read the files.
  • B. Upload log files from the on-premises server to an Amazon EC2 instance and have the instance forward the logs to CloudWatch.
  • C. Install an AWS SDK on the on-premises server to automatically send logs to CloudWatch.
  • D. Download the CloudWatch agent to the on-premises server. Configure the agent to use IAM user credentials with permissions for CloudWatch.

Answer: D


NEW QUESTION # 310
A healthcare company uses AWS Amplify to host a patient management system. The system uses Amazon API Gateway to expose RESTful APIs. The backend logic of the system is handled by AWS Lambda functions.
One of the Lambda functions receives patient data that includes personally identifiable information (PII). The Lambda function sends the patient data to an Amazon DynamoDB table. The company must encrypt all patient data at rest and in transit before the data is stored in DynamoDB.

  • A. Configure the Lambda function to use AWS KMS keys with the AWS Database Encryption SDK to encrypt the patient data before sending the data to DynamoDB.
  • B. Use AWS managed AWS KMS keys to encrypt the data in the DynamoDB table.
  • C. Use an AWS Step Functions workflow to transfer the data to an Amazon SQS queue. Configure a Lambda function to encrypt the data in the queue before sending the data to the DynamoDB table.
  • D. Configure a DynamoDB stream on the table to invoke a Lambda function. Configure the Lambda function to use an AWS KMS key to encrypt the DynamoDB table and to update the table.

Answer: A

Explanation:
Comprehensive Detailed Explanation with all AWS Reference
Why Option A is Correct:
Encrypting PII at rest and in transit before storing it in DynamoDB ensures end-to-end security. Using the AWS Database Encryption SDK with KMS keys allows the Lambda function to encrypt data before transmission, meeting security and compliance requirements.
Why Other Options are Incorrect:
Option B: While AWS-managed KMS keys encrypt DynamoDB data at rest, they do not encrypt data in transit.
Option C: DynamoDB streams process updates after the data is written to the table, failing to encrypt PII in transit.
Option D: Step Functions and SQS add unnecessary complexity and still require encryption logic for both transit and at rest.

NEW QUESTION # 311
A company is migrating its PostgreSQL database into the AWS Cloud. The company wants to use a database that will secure and regularly rotate database credentials. The company wants a solution that does not require additional programming overhead.
Which solution will meet these requirements?

  • A. Use Amazon Aurora PostgreSQL for the database. Store the database credentials in AWS Secrets Manager Turn on rotation.
  • B. Use Amazon DynamoDB for the database. Store the database credentials in AWS Systems Manager Parameter Store Turn on rotation.
  • C. Use Amazon DynamoDB for the database. Store the database credentials in AWS Secrets Manager Turn on rotation.
  • D. Use Amazon Aurora PostgreSQL tor the database. Store the database credentials in AWS Systems Manager Parameter Store Turn on rotation.

Answer: A

Explanation:
Explanation
This solution meets the requirements because it uses a PostgreSQL-compatible database that can secure and regularly rotate database credentials without requiring additional programming overhead. Amazon Aurora PostgreSQL is a relational database service that is compatible with PostgreSQL and offers high performance, availability, and scalability. AWS Secrets Manager is a service that helps you protect secrets needed to access your applications, services, and IT resources. You can store database credentials in AWS Secrets Manager and use them to access your Aurora PostgreSQL database. You can also enable automatic rotation of your secrets according to a schedule or an event. AWS Secrets Manager handles the complexity of rotating secrets for you, such as generating new passwords and updating your database with the new credentials. Using Amazon DynamoDB for the database will not meet the requirements because it is a NoSQL database that is not compatible with PostgreSQL. Using AWS Systems Manager Parameter Store for storing and rotating database credentials will require additional programming overhead to integrate with your database.


NEW QUESTION # 312
A company is migrating its PostgreSQL database into the AWS Cloud. The company wants to use a database that will secure and regularly rotate database credentials. The company wants a solution that does not require additional programming overhead.
Which solution will meet these requirements?

  • A. Use Amazon Aurora PostgreSQL for the database. Store the database credentials in AWS Systems Manager Parameter Store. Turn on rotation.
  • B. Use Amazon Aurora PostgreSQL for the database. Store the database credentials in AWS Secrets Manager. Turn on rotation.
  • C. Use Amazon DynamoDB for the database. Store the database credentials in AWS Systems Manager Parameter Store. Turn on rotation.
  • D. Use Amazon DynamoDB for the database. Store the database credentials in AWS Secrets Manager. Turn on rotation.

Answer: B

Explanation:
Using a database that secures and regularly changes database credentials: Amazon Aurora PostgreSQL offers built-in credential rotation, which allows you to change database credentials at regular intervals.
Solution that requires no additional programming overhead: Amazon Aurora PostgreSQL credential rotation is fully automated, so it requires no additional programming overhead.


NEW QUESTION # 313
A company has a website that is developed in PHP and is launched using AWS Elastic Beanstalk. There is a new version of the website that needs to be deployed in the Elastic Beanstalk environment. The company cannot tolerate having the website offline if an update fails. Deployments must have minimal impact and rollback as soon as possible.

  • A. Rolling
  • B. Immutable
  • C. All at once
  • D. Snapshots

Answer: B

Explanation:
The Immutable deployment method is the best choice when a company requires minimal downtime and automatic rollback in case of a failure. Here's why:
In Immutable deployments, a new set of instances is launched with the updated version. These instances are tested and validated before they replace the old instances. This ensures zero downtime and immediate rollback if the deployment fails.
All at once (A) causes downtime because the update replaces all instances simultaneously.
Rolling deployments (B) update a few instances at a time, but if a failure occurs midway, downtime or partial unavailability can happen.
Snapshots (C) are not a deployment strategy in Elastic Beanstalk.
