Cost-Optimized Architecture II

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 40

A social media company needs to transfer 800 TB of data from an on-premises network attached storage system to AWS Cloud. For compliance reasons, the transfer must be completed within 2 weeks. The data is sensitive and contains PII; it must be encrypted during the transaction. The company’s internet supports an upload of up to 100 Mbps.

Which solution will meet these requirements most cost-effectively?

A. Encrypt the data using a customer-managed key. Use S3 multi-part upload to transfer files over HTTPS to the S3 bucket.

B. Use the AWS Snow Family console to order multiple edge-optimized devices. Use devices to transfer data to S3.

C. Set up an AWS Direct Connect Connection between the company and the nearest region. Transfer data to an S3 bucket over a VPN connection.

D. Create a VPN connection between the on-premises network storage and the nearest AWS region and transfer data to the S3 bucket.

Question 41

A company plans to optimize the cost to fit applications running on AWS. The application uses EC2 instances, API Gateway, Fargate, and AWS Lambda. 

EC2 runs for data cleaning and ingestion layer for the application. EC2 load will be unpredictable and interrupted at any time. The application’s static frontend is running on Fargate; the API Gateway serves the API, whereas Lambda responds to the API requests. 

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

A. Use Spot Instances for data cleaning and ingestion to the application. Configure the S3 bucket to host the frontend of the application. 

B. Use On-Demand Instances for data cleaning and ingestion to the application. Configure the S3 bucket to host the frontend of the application. 

C. Use Spot Instances for data cleaning and ingestion to the application. Configure another Lambda function to host the frontend of the application. 

D. Use Saving Plans to purchase 1-year instances for data cleaning and ingestion to the application. Configure the S3 bucket to host the frontend of the application. 

Question 42

A company plans to migrate its existing monolith application to AWS Cloud. The compnay wants to maintain much of the code of the application. However the company plans to divide the application into smaller functional components managed by different teams. The company requires a highly available and scalable solution to meet these requirements.

As a solutions architect, provide a solution to meet these requirements in a cost-efficient manner. 

A. Configure AWS Lambda to host the application and integrate the application with the API Gateway. 

B. Configure EC2 to host the application and integrate the application with the API Gateway. Set up an Application Load Balancer to forward requests to the Auto Scaling group as a target. 

C. Configure AWS Beanstalk to host the application and integrate the application with the API Gateway. Set up an Application Load Balancer to forward requests to healthy targets. 

D. Configure an ECS cluster with Fargate as infrastructure to host the application. Set up an Application Load Balancer to forward requests to the ECS cluster as the target. 

Question 43

A media company plans to migrate from an on-premises system to the AWS Cloud. The company requires 12 TB of storage with maximum I/O performance for video processing, 280 TB of highly available storage for storing the content, and petabyte size storage to archive the media that is not in use anymore. 

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

A. Configure Amazon EBS for maximum I/O performance, Amazon S3 Intelligent-Tiering as highly available data storage, and S3 Glacier for archival data. 

B. Configure Amazon EBS for maximum I/O performance, Amazon S3 as highly available data storage, and S3 Glacier for archival data. 

C. Configure Amazon EC2 instance store for maximum I/O performance, Amazon S3 as highly available data storage, and S3 Glacier for archival data. 

D. Configure Amazon EC2 instance store for maximum I/O performance, Amazon EBS as highly available data storage, and S3 Glacier for archival data. 

Question 44

A company is deploying a web application on AWS Cloud. The application runs on EC2 instances in an Auto Scaling group behind an Application Load Balancer. The application will provide access to the repository of text documents of about 600 TB. The company anticipates high demand during peak hours and wants to ensure the high availability of the storage component of the application.

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

A. Configure the Amazon Elastic File System to store the files.

B. Configure the Amazon FSx for Lustre to store the files.

C. Configure the Amazon Elastic Block Storage to store the files.

D. Configure the Amazon S3 bucket to store the files.
