Which action will meet these requirements?

A company has an application that runs only on Amazon EC2 Spot Instances. The instances run in an Amazon EC2 Auto Scaling group with scheduled scaling actions.

However, the capacity does not always increase at the scheduled times, and instances terminate many times a day. A Sysops administrator must ensure that the instances launch on time and have fewer interruptions.

Which action will meet these requirements?
A . Specify the capacity-optimized allocation strategy for Spot Instances. Add more instance types to the Auto Scaling group.
B . Specify the capacity-optimized allocation strategy for Spot Instances. Increase the size of the instances in the Auto Scaling group.
C . Specify the lowest-price allocation strategy for Spot Instances. Add more instance types to the Auto Scaling group.
D . Specify the lowest-price allocation strategy for Spot Instances. Increase the size of the instances in the Auto Scaling group.

Answer: A

Explanation:

Specifying the capacity-optimized allocation strategy for Spot Instances and adding more instance types to the Auto Scaling group is the best action to meet the requirements. Increasing the size of the instances in the Auto Scaling group will not necessarily help with the launch time or reduce interruptions, as the Spot Instances could still be interrupted even with larger instance sizes.
