[All AWS Certified SysOps Administrator - Associate Questions]

A SysOps administrator is setting up a fleet of Amazon EC2 instances in an Auto Scaling group for an application. The fleet should have 50% CPU available at all times to accommodate bursts of traffic. The load will increase significantly between the hours of 09:00 and 17:00, 7 days a week.

How should the SysOps administrator configure the scaling of the EC2 instances to meet these requirements?

A. Create a target tracking scaling policy that runs when the CPU utilization is higher than 90%.
B. Create a target tracking scaling policy that runs when the CPU utilization is higher than 50%. Create a scheduled scaling policy that ensures that the fleet is available at 09:00. Create a second scheduled scaling policy that scales in the fleet at 17:00.
C. Set the Auto Scaling group to start with 2 instances by setting the desired instances, maximum instances, and minimum instances to 2. Create a scheduled scaling policy that ensures that the fleet is available at 09:00.
D. Create a scheduled scaling policy that ensures that the fleet is available at 09:00. Create a second scheduled scaling policy that scales in the fleet at 17:00.

Create a target tracking scaling policy that runs when the CPU utilization is higher than 50%: This ensures that the fleet will have 50% CPU available at all times to accommodate bursts of traffic. Create a scheduled scaling policy that ensures that the fleet is available at 09:00: By scheduling the scaling action, the SysOps administrator can ensure that the number of instances is increased before the load increases significantly at 09:00. Create a second scheduled scaling policy that scales in the fleet at 17:00: Similarly, this second scheduled scaling policy allows scaling in the fleet after the peak hours are over at 17:00, which helps in optimizing costs during low traffic periods.
