A batch-processing ASG wants maximum Spot savings while tolerating interruptions — the fleet should draw from many instance types and Spot capacity pools. Which feature does this?
A.One Spot request per instance type
Single-type Spot requests have no diversification or auto-replacement.
B.Mixed Instances Policy with multiple instance types + allocation strategy
Multi-type + multi-pool + allocation strategy. Correct.
C.On-Demand with scheduled scaling
On-Demand doesn't get Spot discounts.
D.EC2 Fleet without an ASG
Fleet is one-time launch — ASG provides ongoing desired-capacity management.
Why this answer
Mixed Instances Policy lets an ASG blend On-Demand + Spot across multiple instance types; capacity-optimized Spot allocation picks pools least likely to interrupt. Diversification across pools is THE Spot resilience strategy.
