Topic 1 Question 281
A SysOps administrator needs to provision a new fleet of Amazon EC2 Spot Instances in an Amazon EC2 Auto Scaling group. The Auto Scaling group will use a wide range of instance types. The configured fleet must come from pools that have the most availability for the number of instances that are launched.
Which solution will meet these requirements?
Launch the Spot Instances up to the maximum capacity of the Auto Scaling group.
Launch the Spot Instances by using the diversified strategy.
Launch the Spot Instances by using the capacity optimized strategy.
Use the Spot Instance advisor to help determine the best Spot allocation strategy.

"The Spot Instance advisor helps you determine pools with the least chance of interruption and provides the savings you get over on-demand rates." https://aws.amazon.com/ec2/spot/instance-advisor/

Tip: Deploying your application across many instance types will further enhance availability. Consider using EC2 Autoscaling, which makes diversification across multiple instance types and availability zones easier.
We recommend starting with instance types having lower frequency of being interrupted and adding more instance types as you improve your application’s flexibility and fault tolerance. See the Best Practices section for more tips and tricks.
The average frequency of interruption across all Regions and instance types is <5%.
