Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 473 discussion

A https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/environments-cfg-autoscaling-scheduledactions.html

A - Scheduled scaling is the solution here, while "using the least amount of settings possible" - Beanstalk vs moving to ECS - ECS requires MORE CONFIGURATION / SETTINGS (task and service definitions, configuring ECS container agent) than Beanstalk (upload application code) - Beanstalk supports scheduled scaling - https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/environments-cfg-autoscaling-scheduledactions.html

A is the answer

It can be scheduled at Lunch hour as we already know when scaling is needed

Time-based scaling helps you more efficiently and easily plan for predictable load changes based on your traffic patterns. You can proactively scale your application in advance of expected traffic through time-based scaling instead of waiting for your scaling action to be triggered by metrics. https://aws.amazon.com/about-aws/whats-new/2015/05/aws-elastic-beanstalk-supports-time-based-scaling/

A is correct

AAAAAAAAAAAA

Vote A

This is a badly written question. It says “users are experiencing poor response times during lunch hours.” Proper answer should include scheduled autoscaling not load based. When the lunch time spike comes it will take min 10-15 min to autoscaled EC2 VMs can be ready. I didn't like this.

For least amount of settings possible, A is the good answer

Why not D ???

A vs C? Perhaps A is with least changes. Loadbalancers in general have Scheduled, Predictive and Dynamic Scaling Options( Simple,Step,Target Tracking).

A. No dudes.

least amount of configuration -> Elastic BeanStalk , A

Agreed that answer is (A), Elastic Beanstalk supports time based scaling, since we are aware that the application performance slows down during the lunch hours. https://aws.amazon.com/about-aws/whats-new/2015/05/aws-elastic-beanstalk-supports-time-based-scaling/
