AWS Certified SysOps Administrator – Associate — Question 200

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?

Answer options

• A. Launch the Spot Instances up to the maximum capacity of the Auto Scaling group.
• B. Launch the Spot Instances by using the diversified strategy.
• C. Launch the Spot Instances by using the capacity optimized strategy.
• D. Use the Spot Instance advisor to help determine the best Spot allocation strategy.

Correct answer: C

Explanation

The capacity optimized strategy is designed to prioritize Spot Instance pools that have a lower chance of interruption, ensuring higher availability for instance launches. The diversified strategy (option B) spreads instances across multiple pools but may not guarantee the highest availability. Options A and D do not specifically target availability based on the instance pools.
