Amazon AWS Certified Developer - Associate Sample Questions (Q102-Q107):

NEW QUESTION # 102
An application routinely processes large numbers of Amazon S3 GET requests each second. A developer wants to increase the number of requests that the application can handle in parallel. What should the developer do to achieve this goal?

A. Configure AWS Global Accelerator for Amazon S3.
B. Move all S3 objects into a single object prefix.
C. Configure AWS Direct Connect for Amazon S3.
D. Partition S3 objects by object prefixes.

Answer: D

Explanation:
Amazon S3 performance scales automatically. Each prefix in an S3 bucket can handle at least 3,500 PUT
/COPY/POST/DELETE and 5,500 GET requests per second. There are no limits to the number of prefixes in a bucket. To increase parallel throughput, a developer should partition the data into multiple prefixes. This distributes the request load across multiple partitions of the S3 index, effectively scaling the performance of the application.

NEW QUESTION # 103
A company has on-premises data centers that run an image processing service. The service consists of containerized applications that run on Kubernetes clusters. All the applications have access to the same NFS share for files and data storage.
The company is running out of NFS capacity in the data centers and needs to migrate to AWS as soon as possible. The Kubernetes clusters must be highly available on AWS.
Which combination of actions will meet these requirements? (Choose two.)

A. Create an Amazon Elastic Kubernetes Service (Amazon EKS) cluster to run the applications.
Configure each node of the cluster to mount the Amazon Elastic Block Store (Amazon EBS) volume at the required path for the container images.
B. Transfer the information that is in the NFS share to an Amazon Elastic Block Store (Amazon EBS) volume. Upload the container images to Amazon Elastic Container Registry (Amazon ECR).
C. Create an Amazon Elastic Container Service (Amazon ECS) cluster to run the applications.
Configure each node of the cluster to mount the Amazon Elastic Block Store (Amazon EBS) volume at the required path for the container images.
D. Create an Amazon Elastic Kubernetes Service (Amazon EKS) cluster to run the applications.Configure each node of the cluster to mount the Amazon Elastic File System (Amazon EFS) volume at the required path for the container images.
E. Transfer the information that is in the NFS share to an Amazon Elastic File System (Amazon EFS) volume. Upload the container images to Amazon Elastic Container Registry (Amazon ECR).

Answer: D,E

NEW QUESTION # 104
A company has an application that uses Amazon Cognito user pools as an identity provider. The company must secure access to user records. The company has set up multi-factor authentication (MFA). The company also wants to send a login activity notification by email every time a user logs in.
What is the MOST operationally efficient solution that meets this requirement?

A. Create an AWS Lambda function that uses Amazon Simple Email Service (Amazon SES) to send the email notification. Add an Amazon API Gateway API to invoke the function. Call the API from the client side when login confirmation is received.
B. Create an AWS Lambda function that uses Amazon Simple Email Service (Amazon SES) to send the email notification. Add an Amazon Cognito post authentication Lambda trigger for the function.
C. Configure Amazon Cognito to stream all logs to Amazon Kinesis Data Firehose. Create an AWS Lambda function to process the streamed logs and to send the email notification based on the login status of each user.
D. Create an AWS Lambda function that uses Amazon Simple Email Service (Amazon SES) to send the email notification. Create an Amazon CloudWatch Logs log subscription filter to invoke the function based on the login status.

Answer: B

Explanation:
Amazon Cognito user pools support Lambda triggers, which are custom functions that can be executed at various stages of the user pool workflow. A post authentication Lambda trigger can be used to perform custom actions after a user is authenticated, such as sending an email notification. Amazon SES is a cloud-based email sending service that can be used to send transactional or marketing emails. A Lambda function can use the Amazon SES API to send an email to the user's email address after the user logs in successfully. Reference: Post authentication Lambda trigger

NEW QUESTION # 105
A developer is building a web and mobile application for two types of users: regular users and guest users. Regular users are required to log in, but guest users do not log in. Users should see only their data, regardless of whether they authenticate. Users need AWS credentials before they can access AWS resources.

A. Set up an IAM user that has permissions to the required resources. Hardcode the IAM credentials in the web and mobile application.
B. Generate temporary credentials. Store the temporary credentials in AWS Secrets Manager. Use the temporary credentials to access the required resources.
C. Generate temporary keys that are stored in AWS KMS. Use the temporary keys to access the required resources.
D. Use an Amazon Cognito identity pool to generate temporary AWS credentials that are linked to an unauthenticated role that has access to the required resources.

Answer: D

Explanation:
Comprehensive and Detailed Step-by-Step
Option A: Amazon Cognito Identity Pool with Unauthenticated Role
Cognito identity pools can generate temporary AWS credentials for both authenticated and unauthenticated users.
For guest users, Cognito assigns an unauthenticated role with limited permissions, ensuring secure access to only their resources.
This is the most secure and efficient solution for managing AWS credentials dynamically without hardcoding or storing them.
Why Other Options Are Incorrect:
Option B: Hardcoding IAM credentials in the application is insecure and violates best practices.
Option C and D: Temporary keys stored in KMS or Secrets Manager require additional implementation overhead and do not inherently manage user-specific access.
Reference:
Amazon Cognito Identity Pools

NEW QUESTION # 106
A company is running Amazon EC2 instances in multiple AWS accounts. A developer needs to implement an application that collects all the lifecycle events of the EC2 instances. The application needs to store the lifecycle events in a single Amazon Simple Queue Service (Amazon SQS) queue in the company's main AWS account for further processing.
Which solution will meet these requirements?

A. Configure the permissions on the main account event bus to receive events from all accounts. Create an Amazon EventBridge rule in each account to send all the EC2 instance lifecycle events to the main account event bus. Add an EventBridge rule to the main account event bus that matches all EC2 instance lifecycle events. Set the SQS queue as a target for the rule.
B. Use the resource policies of the SQS queue in the main account to give each account permissions to write to that SQS queue. Add to the Amazon EventBridge event bus of each account an EventBridge rule that matches all EC2 instance lifecycle events. Add the SQS queue in the main account as a target of the rule.
C. Configure Amazon EC2 to deliver the EC2 instance lifecycle events from all accounts to the Amazon EventBridge event bus of the main account. Add an EventBridge rule to the event bus of the main account that matches all EC2 instance lifecycle events. Add the SQS queue as a target of the rule.
D. Write an AWS Lambda function that scans through all EC2 instances in the company accounts to detect EC2 instance lifecycle changes. Configure the Lambda function to write a notification message to the SQS queue in the main account if the function detects an EC2 instance lifecycle change. Add an Amazon EventBridge scheduled rule that invokes the Lambda function every minute.

Answer: A

Explanation:
Amazon EC2 instances can send the state-change notification events to Amazon EventBridge. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/monitoring-instance-state-changes.html Amazon EventBridge can send and receive events between event buses in AWS accounts. https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-cross-account.html
