Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03

Question #: 930
Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company has an employee web portal. Employees log in to the portal to view payroll details. The company is developing a new system to give employees the ability to upload scanned documents for reimbursement. The company runs a program to extract text-based data from the documents and attach the extracted information to each employee’s reimbursement IDs for processing.

The employee web portal requires 100% uptime. The document extract program runs infrequently throughout the day on an on-demand basis. The company wants to build a scalable and cost-effective new system that will require minimal changes to the existing web portal. The company does not want to make any code changes.

Which solution will meet these requirements with the LEAST implementation effort?

A. Run Amazon EC2 On-Demand Instances in an Auto Scaling group for the web portal. Use an AWS Lambda function to run the document extract program. Invoke the Lambda function when an employee uploads a new reimbursement document.
B. Run Amazon EC2 Spot Instances in an Auto Scaling group for the web portal. Run the document extract program on EC2 Spot Instances. Start document extract program instances when an employee uploads a new reimbursement document.
C. Purchase a Savings Plan to run the web portal and the document extract program. Run the web portal and the document extract program in an Auto Scaling group.
D. Create an Amazon S3 bucket to host the web portal. Use Amazon API Gateway and an AWS Lambda function for the existing functionalities. Use the Lambda function to run the document extract program. Invoke the Lambda function when the API that is associated with a new document upload is called.

i hate these types of questions . there is no perfect answer A:on demand "not cost-effective " , also , how do you want to invoke Lambda . there is no API call B: spot instance ("web portal requires 100% uptime") D:s3 is for static website . it can work but payroll needs to update every 2 weeks and require extensive code change C in my opinion is the only correct answer. it is scalable "ASG", no code change and cost effective "saving plan"

is this supposed to be a confusing question? C is scalable and most cost effective.

Selected Answer: C

Spot Instances are not suitable for workloads requiring 100% uptime then B is out. D is the best solution but it requires some implementation effort. Savings plan (that include Lambda too...) is cheaper than on-demand (option A). Moreover, C doesn't require any code change or other AWS services.

Selected Answer: A

Answer: A This solution offers the most scalable and cost-effective approach with minimal changes to the existing web portal and no code modifications. Why Not Other Options?: Option B (Spot Instances): Spot Instances are not suitable for workloads requiring 100% uptime, as they can be terminated by AWS with short notice. Option C (Savings Plan): A Savings Plan could reduce costs but does not address the requirement for running the document extraction program efficiently or without code changes. Option D (S3 with API Gateway and Lambda): This would require significant changes to the existing web portal setup, including moving the portal to S3 and reconfiguring its architecture, which contradicts the requirement of minimal implementation effort and no code change.

D makes more sense if the company asks to redesign the whole thing to achieve better operational management, performance, cost effective, etc. However, it requires us to provide solution with MINIMUM change... thus A it is I guess.

Selected Answer: A

"The company does not want to make any code changes." Option D requires a complete re-architecture of the web portal to be hosted on Amazon S3 and API Gateway, which involves significant changes to the existing system. This does not align with the requirement of minimal changes to the current setup.
