Amazon AWS Certified Developer - Associate Sample Questions (Q114-Q119):

NEW QUESTION # 114
A company has a new application. The company needs to secure sensitive configuration data such as database connection strings, application license codes, and API keys that the application uses to access external resources. The company must track access to the configuration data for auditing purposes. The resources are managed outside the application.
The company is not required to manage rotation of the connection strings, license codes, and API keys in the application. The company must implement a solution to securely store the configuration data and to give the application access to the configuration data. The solution must comply with security best practices.
Which solution will meet these requirements MOST cost-effectively?

  • A. Store the configuration data in AWS Systems Manager Parameter Store. Grant the application access by using IAM policies.
  • B. Store the configuration data in an encrypted file on the source code bundle. Grant the application access by using IAM policies.
  • C. Store the configuration data on an Amazon Elastic Block Store (Amazon EBS) encrypted volume.
    Attach the EBS volume to an Amazon EC2 instance to provide the application with access to the data.
  • D. Store the configuration data in AWS Secrets Manager. Grant the application access by using IAM policies.

Answer: A

https://docs.aws.amazon.com/managedservices/latest/userguide/sys-man-param-store.html AWS Systems Manager Parameter Store (AMS SSPS):
AWS Systems Manager Parameter Store provides secure, hierarchical storage for configuration data management and secrets management. You can store data such as passwords, database strings, and license codes as parameter values.


NEW QUESTION # 115
A developer is creating a serverless application that uses an AWS Lambda function. The developer will use AWS CloudFormation to deploy the application. The application will write logs to Amazon CloudWatch Logs. The developer has created a log group in a CloudFormation template for the application to use. The developer needs to modify the CloudFormation template to make the name of the log group available to the application at runtime.
Which solution will meet this requirement?

  • A. Use the CloudFormation template's Mappings section to specify the log group's name for the application.
  • B. Pass the log group's Amazon Resource Name (ARN) as an environment variable to the Lambda function.
  • C. Pass the log group's name to the application in the user data section of the CloudFormation template.
  • D. Use the AWS::Include transform in CloudFormation to provide the log group's name to the application.

Answer: B


NEW QUESTION # 116
A developer must analyze performance issues with production-distributed applications written as AWS Lambda functions. These distributed Lambda applications invoke other components that make up me applications. How should the developer identify and troubleshoot the root cause of the performance issues in production?

  • A. Add logging statements to the Lambda functions. then use Amazon CloudWatch to view the logs.
  • B. Use AWS X-Ray. then examine the segments and errors.
  • C. Run Amazon inspector agents and then analyze performance.
  • D. Use AWS CloudTrail and then examine the logs.

Answer: B

Explanation:
This solution will meet the requirements by using AWS X-Ray to analyze and debug the performance issues with the distributed Lambda applications. AWS X-Ray is a service that collects data about requests that the applications serve, and provides tools to view, filter, and gain insights into that data. The developer can use AWS X-Ray to identify the root cause of the performance issues by examining the segments and errors that show the details of each request and the components that make up the applications. Option A is not optimal because it will use logging statements and Amazon CloudWatch, which may not provide enough information or visibility into the distributed applications. Option B is not optimal because it will use AWS CloudTrail, which is a service that records API calls and events for AWS services, not application performance data.
Option D is not optimal because it will use Amazon Inspector, which is a service that helps improve the security and compliance of applications on Amazon EC2 instances, not Lambda functions.

NEW QUESTION # 117
A developer is working on an app for a company that uses an Amazon DynamoDB table named Orders to store customer orders. The table uses OrderID as the partition key and there is no sort key. The table contains more than 100,000 records. The developer needs to add a functionality that will retrieve all Orders records that contain an OrderSource attribute with the MobileApp value.
Which solution will improve the user experience in the MOST efficient way?

  • A. Create a global secondary index (GSI) with OrderSource as the partition key. Perform a Query operation by using MobileApp as the key.
  • B. Create a global secondary index (GSI) with OrderSource as the sort key. Perform a Query operation by using MobileApp as the key.
  • C. Create a local secondary index (LSI) with OrderSource as the partition key. Perform a Query operation by using MobileApp as the key.
  • D. Perform a Scan operation on the Orders table. Provide a QueryFilter condition to filter to only the items where the OrderSource attribute is equal to the MobileApp value.

Answer: A


NEW QUESTION # 118
A developer wants to add request validation to a production environment Amazon API Gateway API. The developer needs to test the changes before the API is deployed to the production environment. For the test, the developer will send test requests to the API through a testing tool.
Which solution will meet these requirements with the LEAST operational overhead?

  • A. Modify the existing API to add request validation. Deploy the updated API to a new API Gateway stage. Perform the tests. Deploy the updated API to the API Gateway production stage.
  • B. Clone the existing API. Modify the new API to add request validation. Perform the tests. Modify the existing API to add request validation. Deploy the existing API to production.
  • C. Export the existing API to an OpenAPI file. Create a new API. Import the OpenAPI file. Modify the new API to add request validation. Perform the tests. Modify the existing API to add request validation. Deploy the existing API to production.
  • D. Create a new API. Add the necessary resources and methods, including new request validation.
    Perform the tests. Modify the existing API to add request validation. Deploy the existing API to production

Answer: A

Explanation:
In this option, you are making changes directly to the existing API, adding request validation.
Then, you deploy the updated API to a new API Gateway stage, which allows you to test the changes without affecting the production environment. After performing the tests and ensuring everything works as expected, you can then deploy the updated API to the production stage, thus minimizing operational overhead.
