Amazon AWS Certified Developer - Associate Sample Questions (Q22-Q27):

NEW QUESTION # 22
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 Elastic Container Service (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. Add a capacity provider to manage instances.
C. Create an Amazon ECS cluster and add the managed node groups feature to run the application.
D. Define a task definition with an AWS Fargate launch type.

Answer: C

NEW QUESTION # 23
A company is building a content authoring application. The application has multiple user groups, such as content creator, reviewer, approver, and administrator. The company needs to assign users fine-grained permissions for specific parts of the application.
The company needs a solution to configure, maintain, and analyze user permissions. The company wants a solution that can be easily adapted to work with newer applications in the future. The company must use a third-party OpenID Connect (OIDC) identity provider (IdP) to authenticate users.

A. Configure an Amazon Cognito identity pool for the application. Use the identity pool identities within the application to manage user permissions.
B. Use Amazon Verified Permissions to set up user permissions. Integrate Verified Permissions with a third-party IdP. Configure the application to request authorization decisions from Verified Permissions.
C. Set up an IAM role for each user group. Assign users appropriate IAM roles. Configure the application to determine appropriate permissions for each user based on the user's IAM role.
D. Configure the application to check user permissions upon request. Configure the application logic to manage user permissions.

Answer: B

Explanation:
Comprehensive Detailed Explanation with all AWS Reference
Why Option C is Correct:
Amazon Verified Permissions provides fine-grained access control capabilities, making it ideal for managing complex user permissions. It integrates with OIDC IdPs for authentication and allows applications to request authorization decisions dynamically. It is also easily adaptable to newer applications.
Why Other Options are Incorrect:
Option A: Cognito identity pools do not natively support fine-grained permission analysis or management.
Option B: Managing permissions in application logic adds significant operational overhead.
Option D: IAM roles are not designed for application-specific fine-grained access control and are more suitable for resource-level permissions.
AWS Documentation Reference:
Amazon Verified Permissions

NEW QUESTION # 24
A developer is building an application that includes an AWS Lambda function that is written in .NET Core. The Lambda function's code needs to interact with Amazon DynamoDB tables and Amazon S3 buckets. The developer must minimize the Lambda function's deployment time and invocation duration.
Which solution will meet these requirements?

A. Include only the AWS SDK for .NET modules for DynamoDB and Amazon S3 in the Lambda function's deployment package.
B. Include the entire AWS SDK for .NET in the Lambda function's deployment package.
C. Increase the Lambda function's memory.
D. Configure the Lambda function to download the AWS SDK for .NET from an S3 bucket at runtime.

Answer: A

NEW QUESTION # 25
A developer needs to migrate an online retail application to AWS to handle an anticipated increase in traffic.
The application currently runs on two servers: one server for the web application and another server for the database. The web server renders webpages and manages session state in memory. The database server hosts a MySQL database that contains order details. When traffic to the application is heavy, the memory usage for the web server approaches 100% and the application slows down considerably.
The developer has found that most of the memory increase and performance decrease is related to the load of managing additional user sessions. For the web server migration, the developer will use Amazon EC2 instances with an Auto Scaling group behind an Application Load Balancer.
Which additional set of changes should the developer make to the application to improve the application's performance?

A. Use Amazon ElastiCache for Memcached to store and manage the session data. Use an Amazon RDS for MySQL DB instance to store the application data.
B. Use an EC2 instance to host the MySQL database. Store the session data and the application data in the MySQL database.
C. Use the EC2 instance store to manage the session data. Use an Amazon RDS for MySQL DB instance to store the application data.
D. Use Amazon ElastiCache for Memcached to store and manage the session data and the application data.

Answer: A

Explanation:
Using Amazon ElastiCache for Memcached to store and manage the session data will reduce the memory load and improve the performance of the web server. Using Amazon RDS for MySQL DB instance to store the application data will provide a scalable, reliable, and managed database service. Option A is not optimal because it does not address the memory issue of the web server. Option C is not optimal because it does not provide a persistent storage for the application data. Option D is not optimal because it does not provide a high availability and durability for the session data.
References: Amazon ElastiCache, Amazon RDS

NEW QUESTION # 26
A developer is building a containerized application on AWS. The application communicates with a third-party service by using API keys. The developer needs a secure way to store the API keys and pass the API keys to the containerized application.
Which solutions will meet these requirements? (Choose two.)

A. Store the API keys in AWS CloudFormation templates by using base64 encoding. Pass the API keys to the application through container definition environment variables.
B. Add a new AWS CloudFormation parameter to the CloudFormation template. Pass the API keys to the application by using the container definition environment variables.
C. Store the API keys as a SecretString parameter in AWS Secrets Manager. Grant the application access to retrieve the value from Secrets Manager.
D. Store the API keys as a SecureString parameter in AWS Systems Manager Parameter Store.
Grant the application access to retrieve the value from Parameter Store.
E. Embed the API keys in the application. Build the container image on-premises. Upload the container image to Amazon Elastic Container Registry (Amazon ECR).

Answer: B,D
