Which EC2 instance purchasing option will meet these requirements?
A. Reserved Instances
B. Spot Instances
C. On-Demand Instances
D. Dedicated Instances
Show Answer
Correct Answer: C
Explanation: The requirement is for uninterruptible EC2 instances with the ability to provision them as needed and pay by the second. On-Demand Instances provide immediate availability, are not subject to interruption, and support per-second billing (for Linux-based instances). Reserved Instances require long-term commitment, Spot Instances can be interrupted, and Dedicated Instances focus on hardware isolation rather than billing flexibility.

The other options do not provide cost monitoring capabilities.
