A company hosts a website on multiple Amazon EC2 instances that run in an Auto Scaling group. Users are reporting slow responses during peak times between 6 PM and 11 PM every weekend. A SysOps administrator must implement a solution to improve performance during these peak times. What is the MOST operationally efficient solution that meets these requirements?
A) Create a scheduled Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function to increase the desired capacity before peak times.
B) Configure a scheduled scaling action with a recurrence option to change the desired capacity before and after peak times.
C) Create a target tracking scaling policy to add more instances when memory utilization is above 70%.
D) Configure the cooldown period for the Auto Scaling group to modify desired capacity before and after peak times.

Configuring a scheduled scaling action with a recurrence option is the most operationally efficient solution as it automatically adjusts the desired capacity based on a predictable schedule, such as peak times on weekends, without manual intervention.
