Which AWS pricing model gives the biggest discount on EC2 but allows AWS to reclaim the capacity with 2 minutes' notice?
ADedicated Hosts
BOn-Demand
CEC2 Spot Instances
DReserved Instances
Answer & Solution
Correct answer: C. EC2 Spot Instances
Spot can be reclaimed with 2-min notice but offers up to ~90% off. On-demand has no discount; RIs trade flexibility for discount with no preemption; Dedicated Hosts are billed by host and cost more.
