What is the primary goal of right-sizing AWS resources?

To maximize the number of instances running

To ensure resources are not over-provisioned or under-provisioned

To eliminate the need for monitoring

To use the most powerful instance types available

A company runs a batch processing workload on EC2 instances that processes financial reports every night from 2:00 AM to 4:00 AM. The workload is fault-tolerant and can be interrupted. The company wants to minimize compute costs while maintaining the ability to complete the reports by 6:00 AM. What should the company do?

Purchase a 1-year All Upfront Standard Reserved Instance for the instance family and size used by the workload.

Use On-Demand Instances and schedule them to start and stop automatically at the required times.

Use Spot Instances for the batch processing workload, with a diversified instance pool across multiple instance types and Availability Zones.

Purchase a Compute Savings Plan with a 3-year term and No Upfront payment.

A solutions architect is selecting an EC2 instance type for a new application. The application has a steady, predictable workload that uses about 40% of a large instance's CPU. What is the most cost-effective approach?

Select the large instance and enable detailed monitoring

Select the large instance and use a Savings Plan

Select the large instance to allow for future growth

Select a smaller instance that meets the current CPU requirement

A solutions architect is comparing the total cost of ownership (TCO) of running a workload on AWS versus on-premises. What should be included in the TCO calculation?

Hardware, software, operational, and personnel costs for both options

Only the direct costs of AWS services

Only the upfront purchase price of hardware

Only the costs of data transfer and storage

What is a key cost benefit of event-driven architectures using AWS Lambda?

You pay a flat monthly fee for the function

You pay only for the compute time consumed when the function runs

You pay for the underlying servers even when the function is idle

You pay for the number of provisioned concurrency units
