Practice Test 2 | AWS Certified Cloud Practitioner | CLF-C01 | Dumps | Mock Test
You have a distributed application that periodically processes large volumes of data across multiple Amazon EC2 Instances. The application is designed to recover gracefully from Amazon EC2 instance failures. You are required to accomplish this task most cost-effectively.
Which of the following will meet your requirements?
A. Spot Instances
B. Reserved instances
C. Dedicated instances
D. On-Demand instances
Answer – A
When you think of cost effectiveness, you can either have to choose Spot or Reserved instances. Now when you have a regular processing job, the best is to use spot instances. Since your application is designed to recover gracefully from Amazon EC2 instance failures, there is no issue even if you lose the Spot instances.
