A Company Is Running a Flash Sale on Its Website

Multiple Choice

A company is running a flash sale on its website. The website is hosted on burstable performance Amazon EC2 instances in an Auto Scaling group. The Auto Scaling group is configured to launch instances when the CPU utilization is above 70%. A couple of hours into the sale, users report slow load times and error messages for refused connections. A SysOps administrator reviews Amazon CloudWatch metrics and notices that the CPU utilization is at 20% across the entire fleet of instances. The SysOps administrator must restore the website's functionality without making changes to the network infrastructure. Which solution will meet these requirements?

A) Activate unlimited mode for the instances in the Auto Scaling group.
B) Implement an Amazon CloudFront distribution to offload the traffic from the Auto Scaling group.
C) Move the website to a different AWS Region that is closer to the users.
D) Reduce the desired size of the Auto Scaling group to artificially increase CPU average utilization.
