Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 882
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company runs its application by using Amazon EC2 instances and AWS Lambda functions. The EC2 instances run in private subnets of a VPC. The Lambda functions need direct network access to the EC2 instances for the application to work.

The application will run for 1 year. The number of Lambda functions that the application uses will increase during the 1-year period. The company must minimize costs on all application resources.

Which solution will meet these requirements?

  • A. Purchase an EC2 Instance Savings Plan. Connect the Lambda functions to the private subnets that contain the EC2 instances.
  • B. Purchase an EC2 Instance Savings Plan. Connect the Lambda functions to new public subnets in the same VPC where the EC2 instances run.
  • C. Purchase a Compute Savings Plan. Connect the Lambda functions to the private subnets that contain the EC2 instances.
  • D. Purchase a Compute Savings Plan. Keep the Lambda functions in the Lambda service VPC.

Selected Answer: C
Compute Savings Plan: This plan offers significant discounts on Lambda functions compared to on-demand pricing. Since the application will run for a year, a sustained use discount like Compute Savings Plan is ideal. Private Subnets: Lambda functions in private subnets can directly access EC2 instances within the VPC without needing internet access, reducing security risks and potential egress costs.

I confuse this Question. Instance saving plan is cheaper than compute saving plan. https://aws.amazon.com/savingsplans/compute-pricing/
