Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 7 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C02
Question #: 7
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company's application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. On the first day of every month at midnight, the application becomes much slower when the month-end financial calculation batch executes. This causes the CPU utilization of the EC2 instances to immediately peak to 100%, which disrupts the application.
What should a solutions architect recommend to ensure the application is able to handle the workload and avoid downtime?

  • A. Configure an Amazon CloudFront distribution in front of the ALB.
  • B. Configure an EC2 Auto Scaling simple scaling policy based on CPU utilization.
  • C. Configure an EC2 Auto Scaling scheduled scaling policy based on the monthly schedule.
  • D. Configure Amazon ElastiCache to remove some of the workload from the EC2 instances.

Answer - C; Scheduled scaling allows you to set your own scaling schedule. In this case the scaling action can be scheduled to occur just prior to the time that the reports will be run each month. Scaling actions are performed automatically as a function of time and date. This will ensure that there are enough EC2 instances to serve the demand and prevent the application from slowing down. CORRECT: "Configure an EC2 Auto Scaling scheduled scaling policy based on the monthly schedule" is the correct answer.

I agree, because of this clue: "This causes the CPU utilization of the EC2 instances to IMMEDIATELY peak to 100%". You must schedule to scale up b beforehand because the spike takes place IMMEDIATELY.

I go with C as well that makes sense, especially if we have predictable web traffic data insights then it's easy to set the schedule up for scaling/

Scheduled scaling, also known as scheduled auto scaling, is a feature provided by cloud computing platforms like Amazon Web Services (AWS) that allows users to automatically adjust the number of resources (such as compute instances or containers) in a cloud environment based on predefined schedules or conditions. answer is C

The answer is C because the ec2's are already autoscaled and that didnt solve the issue so there has to be another action which is to schedule procedure.

Agreed correct answer should be 'C' as CPU utilization reaches to 100% immediately so it makse sens to have auto scalling policy based on scheduled time.

as the time is predictable, scheduled scaling can be applied in this scenario.

I would go with C, because the issues occurs on schedule (that has factor of predictability). However, As an architect I also look at CPU (B). For example, if i am autoscaling at 7:00 pm that with the understanding the CPU% is taken into consideration as a threshold before it scheduled is triggered. What if the application peaks randomly prior slightly to the triggered scheduled. I would apply the schedule with cpu range of percentage as a buffer in the event random spike occurs around the established time.

Selected Answer: B
If we go with option B, we can simple take care of scenarios where the application can face outage due to lack of resources, sure if we schedule the ASG, we will have some resources available before the CPU utilisation reaches 100%, but here the key is "100%", so if we set the ASG threshold for CPU utilities at 70%, the resources will be available before time, of course give that the application is not spiking the CPU utilisation randomly (from 40% to 80-90% directly)
