High-Performing 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 53

A hospital has recently deployed a serverless application to process the uploaded documents. The application consists of Amazon API Gateway and AWS Lambda; the hospital uses an API Gateway to upload images/documents in PDF and JPEG format. The hospital plans to extract the Personal Health Information (PHI) from the reports.

As a solution architect, which solution will meet these requirements?

A. Use Python libraries to extract the text and detect PHI from the reports.

B. Configure Amazon Textract to extract text from the reports and use Amazon Sagemaker to detect PHI.

C. Configure Amazon Textract to extract text from the reports and use Amazon Comprehend to detect PHI from the extracted text.

D. Configure Amazon Rekognition to extract text from the reports and use Amazon Comprehend to detect PHI from the extracted text.

Question 54

A company’s three-tier application, consisting of a presentation tier, a business logic tier, and a data storage tier, experiences transaction loss when a tier becomes overloaded. The application communicates between tiers using RESTful APIs. The company plans to migrate the application to the AWS Cloud and also wants to explore ways to modernize it.

As a solutions architect design a solution to meet these requirements.

Which of these solutions meets the requirements?

A. Use Amazon Simple Queue Service (SQS) for communication layer and configure API Gateway to direct transactions to AWS lambda function as application layer to process.

B. Configure CloudWatch metrics to analyze the application performance during peak hours and increase the application EC2 instances to meet the requirements.

C. Use Amazon Simple Queue Service (SQS) for the communication layer between application servers on EC2 instances in an AutoScaling Group. Configure CloudWatch metrics to analyze the SQS queue and scale based on the size.

D. Use Amazon Simple Notification Service (SNS) for the communication layer between application servers on EC2 instances in an AutoScaling Group. Configure CloudWatch metrics to analyze the SNS queue and scale based on the size.

Question 55

A company is designing an application storage so users can upload files to an S3 bucket. As the file is uploaded, it requires one-time processing to extract and save the data in JSON format for later analysis.

Demand can vary; on some days, demand will be higher than on other days. Each file must be processed quickly to avoid bottlenecks.
As a solutions architect, provide a solution to meet these requirements with the least operational overhead.

A. Configure an EMR to read text files from the S3 bucket and run scripts to transform data to JSON. Store the JSON files in DynamoDB.

B. Configure the S3 bucket to send an Event notification to an SQS queue. Use EC2 to read text files from the S3 bucket and run scripts to transform data to JSON. Store the JSON files in DynamoDB.

C. Configure the S3 bucket to send an Event notification to an SQS queue. Use the Lambda function to read text files from the S3 bucket and run scripts to transform data to JSON. Store the JSON files in DynamoDB.

D. Configure the S3 bucket to send an Event notification to an SQS queue. Use the Lambda function to read text files from the S3 bucket and run scripts to transform data to JSON. Store the JSON files in the Amazon Aurora DB cluster.

Question 56

A ride-sharing company plans to deploy a three-tier architecture application to track the location of vehicles. The company plans to use the existing data points from the analytics platform. The data points must be accessible from the API Gateway.

As a solutions architect, determine the most viable multi-tier option to meet these requirements.

Which solution will meet the requirements for storing and retrieving the data points?

A. Configure Amazon Athena with an S3 bucket.

B. Configure API Gateway with AWS Lambda.

C. Configure S3 with AWS Glue.

D. Configure API Gateway with Amazon Kinesis Data Analytics.

Question 57

A social media company has its dynamic content hosted on the EC2 instances. The company has SSL certificates on each instance to perform SSL termination. Due to the sudden increase in traffic, instances are reaching their computing capacity. Operations teams have determined that it’s because of each instance’s SSL encryption and decryption.


As a solutions architect, provide a solution that meets these requirements.


A. Configure a new SSL certificate and install ACM on each instance.

B. Configure an EC2 proxy instance. Migrate the SSL certificates to the proxy instances and redirect the connections to the existing instances.

C. Configure an S3 bucket. Migrate the SSL certificates to the S3 bucket and redirect the connections to the S3 bucket for SSL terminations.

D. Import SSL Certificates to ACM. Configure an Application Load Balancer with an HTTPS listener using an ACM SSL certificate.
