Question 1 of 800

A solutions architect is designing a solution where users will be directed to a backup static error page if the primary website is unavailable. The primary website's

DNS records are hosted in Amazon Route 53 where their domain is pointing to an Application Load Balancer (ALB).

Which configuration should the solutions architect use to meet the company's needs while minimizing changes and infrastructure overhead?

Point a Route 53 alias record to an Amazon CloudFront distribution with the ALB as one of its origins. Then, create custom error pages for the distribution.

Set up a Route 53 active-passive failover configuration. Direct traffic to a static error page hosted within an Amazon S3 bucket when Route 53 health checks determine that the ALB endpoint is unhealthy.

Update the Route 53 record to use a latency-based routing policy. Add the backup static error page hosted within an Amazon S3 bucket to the record so the traffic is sent to the most responsive endpoints.

Set up a Route 53 active-active configuration with the ALB and an Amazon EC2 instance hosting a static error page as endpoints. Route 53 will only send requests to the instance if the health checks fail for the ALB.

Correct Answer: B

To achieve the requirement of directing users to a backup static error page if the primary website is unavailable, a Route 53 active-passive failover configuration is ideal. This setup minimizes changes and infrastructure overhead by using health checks to determine the availability of the Application Load Balancer (ALB). When the ALB is found to be unhealthy, Route 53 can smoothly transition the traffic to a static error page hosted within an Amazon S3 bucket. This method ensures high availability and resilience with minimal changes to the existing infrastructure.

Question 2 of 800

A solutions architect is designing a high performance computing (HPC) workload on Amazon EC2. The EC2 instances need to communicate to each other frequently and require network performance with low latency and high throughput.

Which EC2 configuration meets these requirements?

Launch the EC2 instances in a cluster placement group in one Availability Zone.

Launch the EC2 instances in a spread placement group in one Availability Zone.

Launch the EC2 instances in an Auto Scaling group in two Regions and peer the VPCs.

Launch the EC2 instances in an Auto Scaling group spanning multiple Availability Zones.

Correct Answer: A

To achieve low latency and high throughput for high performance computing (HPC) workloads on Amazon EC2, you should use a cluster placement group in one Availability Zone. This configuration packs instances close together, which reduces latency and increases network performance, facilitating the frequent communication required between instances in such workloads.

Question 3 of 800

A company wants to host a scalable web application on AWS. The application will be accessed by users from different geographic regions of the world.

Application users will be able to download and upload unique data up to gigabytes in size. The development team wants a cost-effective solution to minimize upload and download latency and maximize performance.

What should a solutions architect do to accomplish this?

Use Amazon S3 with Transfer Acceleration to host the application.

Use Amazon S3 with CacheControl headers to host the application.

Use Amazon EC2 with Auto Scaling and Amazon CloudFront to host the application.

Use Amazon EC2 with Auto Scaling and Amazon ElastiCache to host the application.

Correct Answer: A

To achieve a cost-effective and high-performance solution for a globally accessible web application involving large data transfers, using Amazon S3 with Transfer Acceleration is the best choice. S3 Transfer Acceleration leverages Amazon CloudFront's globally distributed edge locations to significantly speed up upload and download operations for objects up to several gigabytes in size. This not only reduces latency but also maximizes performance by routing data through optimized network paths, making it an ideal solution for applications with users distributed across different geographic regions.

Question 4 of 800

A company is migrating from an on-premises infrastructure to the AWS Cloud. One of the company's applications stores files on a Windows file server farm that uses Distributed File System Replication (DFSR) to keep data in sync. A solutions architect needs to replace the file server farm.

Which service should the solutions architect use?

Amazon EFS

Amazon FSx

Amazon S3

AWS Storage Gateway

Correct Answer: B

The company needs to replace its Windows file server farm that uses Distributed File System Replication (DFSR) to keep data in sync. Amazon FSx for Windows File Server is specifically designed to provide fully managed, highly reliable file storage that is accessible over the industry-standard Server Message Block (SMB) protocol. It supports DFSR, making it the ideal service for this use case. By using Amazon FSx, the company can maintain the same synchronization functionality in the cloud as they had on-premises.

Question 5 of 800

A company has a legacy application that processes data in two parts. The second part of the process takes longer than the first, so the company has decided to rewrite the application as two microservices running on Amazon ECS that can scale independently.

How should a solutions architect integrate the microservices?

Implement code in microservice 1 to send data to an Amazon S3 bucket. Use S3 event notifications to invoke microservice 2.

Implement code in microservice 1 to publish data to an Amazon SNS topic. Implement code in microservice 2 to subscribe to this topic.

Implement code in microservice 1 to send data to Amazon Kinesis Data Firehose. Implement code in microservice 2 to read from Kinesis Data Firehose.

Implement code in microservice 1 to send data to an Amazon SQS queue. Implement code in microservice 2 to process messages from the queue.

Correct Answer: D

To integrate the two microservices efficiently, the better approach is to use Amazon SQS (Simple Queue Service). Microservice 1 can send data to an SQS queue, and Microservice 2 can process messages from this queue. This solution allows for decoupling of the services, ensuring that Microservice 2 can handle the messages at its own pace without being directly dependent on the processing time of Microservice 1. SQS also provides fault tolerance, scalability, and cost-effectiveness, perfect for systems where the processing times of different parts are not uniform.
