Question 90
A team identifies three independent cloud planning needs. Finding 1: A web application requires full control over the guest operating system and custom long-running server software. Finding 2: An online storefront must increase web server count when traffic rises and reduce it again after demand falls. Finding 3: A site operates several healthy web servers but directs all inbound client requests to one static server address. Which complete response addresses all three findings in order?
Explanation
Correct Answer
For finding 1: EC2 supplies resizable compute instances with customer responsibility for guest software and configuration. For finding 2: Auto Scaling changes the number of eligible instances to match measured demand. For finding 3: Load balancers distribute client requests among registered healthy resources. All three decisions are needed.
Incorrect Answers
For finding 2: Auto Scaling changes the number of eligible instances to match measured demand. That action addresses a different situation: A compute-bound batch workload is slow and the architect chooses storage-optimized EC2 instances solely because the disk is large.
