Practice Test 3 | AWS Certified Solutions Architect Associate | SAA-C03 | Dumps | Mock Test
Your Operations department is using an incident based application hosted on a set of EC2 Instances. These instances are placed behind an Auto Scaling Group to ensure the right number of instances are in place to support the application. The Operations department has expressed dissatisfaction with regard to poor application performance at 9:00 AM each day. However, it is also noted that the system performance returns to optimal at 9:45 AM.
A. Create another Dynamic Scaling Policy to ensure that the scaling happens at 9:00 AM.
B. Add another Auto Scaling group to support the current one.
C. Change the Cool Down Timers for the existing Auto Scaling Group.
D. Add a Scheduled Scaling Policy at 8:30 AM.
Explanation:
Answer – D
Scheduled Scaling can be used to ensure that the capacity is peaked before 9:00 AM each day.
AWS Documentation further mentions the following on Scheduled Scaling:
Scaling based on a schedule allows you to scale your application in response to predictable load changes. For example, every week the traffic to your web application starts to increase on Wednesday, remains high on Thursday, and starts to decrease on Friday. You can plan your scaling activities based on the predictable traffic patterns of your web application.
- Option A is INCORRECT because a scheduled scaling should be used as per the requirements of the question instead of dynamic scaling
- Option B is INCORRECT because adding another autoscaling group will not solve the problem.
- Option C is INCORRECT because changing the cooldown timers of the existing autoscaling group will not meet the requirements of the question
