Resilient Architecture III

Equip yourself with the necessary understanding to confidently tackle exam questions by reviewing assessment questions and explanations against all options.

We'll cover the following

Question 11

A taxation company offers an API to its customers to automate short, complex tax computation inquiries. The computation inquiry takes no longer than 13 minutes. The company has noticed high traffic during the holiday season, which has caused a slow response to customers. The company needs to design a reliable and scalable solution.

What should a solutions architect do to meet these requirements with the least operational overhead?

A. Create a REST API using Amazon API Gateway that accepts the requests. Use AWS Lambda for tax computations.

B. Create a REST API hosted on an EC2 instance. API accepts the requests and uses different EC2 instances in the Autoscaling group for tax computations.

C. Deploy an Application Load Balancer (ALB) with two instances behind it hosting a REST API on the EC2 instance. The EC2 instances perform the required tax computations.

D. Deploy an Application Load Balancer (ALB) with an ECS cluster hosting a REST API. Use the ECS cluster to perform the required tax computations.

Question 12

A video streaming company’s volume backup solution has reached its end of life. The company wants to migrate to the cloud and use AWS as a part of the new backup solution. The company wants to maintain access to the local data while it is backed up and to ensure the data is backed up automatically and securely.

Which solution meets the requirements?

A. Use an AWS Snowball device to migrate the on-premises data to the Amazon S3 bucket.

B. Use AWS Gateway to configure the volume gateway. Use the AWS Gateway appliance on-premises to map the storage gateway volumes to premises storage. Mount storage volumes to provide local access.

C. Use AWS Gateway to configure the file gateway. Use the AWS Gateway application on-premises to map the storage gateway volumes to on-premises storage. Mount storage volumes to provide local access.

D. Use AWS Gateway to configure the volume gateway. Use DMS to migrate the data from on-premises volume storage to AWS volume gateway.

Question 13

A company has a web application that live streams different events and offers on-demand service. The company plans to improve the application’s performance for an upcoming music event. The videos of the event will be live streamed and will also be available on demand. 

As a solutions architect, provide a solution to meet these requirements.

A. AWS CloudFront

B. AWS Global Accelerator

C. Network Load Balancer

D. Route 53
