Question #758 / 1019

A company is deploying a containerized application on AWS and requires high availability across three Availability Zones. The solution must minimize operational overhead and avoid significant application modifications. Which option fulfills these requirements?

A

Use Amazon ECS with AWS Fargate. Configure the service to use a spread placement strategy across Availability Zones and set the desired task count to 3.

B

Use Amazon EKS with self-managed nodes. Configure the Kubernetes Cluster Autoscaler with a minimum node count of 3 across Availability Zones.

C

Deploy EC2 instances in an Auto Scaling group spread across three Availability Zones using a spread placement group, with a minimum capacity of 3.

D

Use AWS Lambda with provisioned concurrency set to 3, distributing the function across multiple Availability Zones.

Question #603 / 1019

The solution must process each data item independently with maximum parallelism and scalability. Which approach provides the MOST scalable and efficient processing?

A

Use the AWS Step Functions Map state in Inline mode to process each item sequentially within a single execution.

B

Use the AWS Step Functions Map state in Distributed mode to process each item in a separate execution for maximum scalability.

Sample Questions

Question #207 / 529

An online retail company is migrating its legacy on-premises Java application to AWS. The application runs on load-balanced frontend web servers, load-balanced application servers, and an Oracle database. The company wants to use AWS managed services where possible and avoid rewriting the application. A solutions architect needs to implement a solution to resolve scaling issues and minimize licensing costs as the application scales. Which solution will meet these requirements MOST cost-effectively?

A

Deploy Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer for the web tier and application tier. Use Amazon Aurora PostgreSQL with AWS Schema Conversion Tool (AWS SCT) and Oracle compatibility extensions to replatform the Oracle database.

B

Create images of all servers using AWS Application Migration Service. Deploy EC2 instances in an Auto Scaling group behind a Network Load Balancer for both tiers. Use Amazon DocumentDB as the database tier.

C

Containerize the web and application tiers using Amazon ECS. Deploy containers behind an Application Load Balancer. Use Amazon RDS for Oracle with Bring Your Own License (BYOL) for the database.

D

Refactor the application into AWS Lambda functions. Use Amazon API Gateway for both tiers. Migrate the database to Amazon Redshift and use Amazon QuickSight for queries.

Question #127 / 529

A logistics company needs to migrate a third-party data processing application to AWS. The third party provides a supported Docker image from a public registry, which can run in multiple containers. The company has divided its operations into regions, each with dedicated processing nodes that handle data specific to their region. To optimize processing times, each region uses its own Docker containers with custom configurations. The company requires the ability to allocate resources cost-effectively based on the number of active containers.

Which solution will meet these requirements with the LEAST operational overhead?

A

Create an Amazon Elastic Kubernetes Service (Amazon EKS) cluster on Amazon EC2. Use the Amazon EKS CLI to deploy the application in pods, using the --tags parameter to assign region-specific tags to the pods.

B

Create an Amazon Elastic Kubernetes Service (Amazon EKS) cluster on AWS Fargate. Deploy the application using the Amazon EKS CLI and apply region-specific tags via the AWS CLI tag-resource API.

C

Create an Amazon Elastic Container Service (Amazon ECS) cluster on Amazon EC2. Use the AWS CLI with run-task to launch containers, applying region-specific tags using the --tags parameter.

D

Create an Amazon Elastic Container Service (Amazon ECS) cluster on AWS Fargate. Use the AWS CLI run-task command with enableECSManagedTags set to true and apply region-specific tags using the --tags parameter.

A

Retry the batch operation immediately.

B

Retry the batch operation with exponential backoff and randomized delay.

C

Update the application to use an AWS software development kit (AWS SDK) to make the requests.

D

Increase the provisioned read capacity of the DynamoDB tables that the operation accesses.

E

Increase the provisioned write capacity of the DynamoDB tables that the operation accesses.

Question #89 / 557

A company is using an Amazon API Gateway REST API endpoint as a webhook to publish events from an on-premises monitoring system to Amazon EventBridge in a central AWS account. The company needs these events to be processed simultaneously in multiple receiver AWS accounts without modifying the monitoring system's configuration.

How can a developer meet these requirements?

B

Convert the API Gateway type to HTTP API and configure an Amazon SNS topic to distribute events to the receiver accounts.

A

Deploy the API Gateway REST API in each receiver account and update the monitoring system's webhook to send events to all API endpoints.

C

Grant the central account's EventBridge permission to send events to the receiver accounts' event buses and configure the EventBridge rule to target these buses.

D

Create an SQS queue in each receiver account, subscribe them to an SNS topic in the central account, and modify the EventBridge rule to publish to the SNS topic.
