Correct Answer: B

Explanation:

Explanation: Auto Scaling is well suited to both applications that have stable demand patterns and that experi-ence hourly, daily, or weekly variability in usage. Whether the demand is predictable or unpredicta-ble auto scaling can be a good choice. If the demand is predictable and long term you may choose reserved instances. If the demand is unpredictable you may choose on-demand or even spot instance (if you can afford to have an instance lost unexpectedly). Reference: http://aws.amazon.com/autoscaling/
