Question 1 of 30
A company is deploying a multi-tier web application on AWS that consists of a front-end web server, an application server, and a database server. The application is expected to handle variable traffic loads throughout the day. To optimize performance and cost, the company decides to implement an Auto Scaling group for the application server and a load balancer in front of the web server. Which of the following configurations would best ensure that the application can scale efficiently while maintaining high availability and minimizing costs?
Configure the Auto Scaling group to use a scheduled scaling policy based on historical traffic patterns and set the minimum instance count to 2 to ensure redundancy.
Set the Auto Scaling group to a fixed instance count of 5 to handle peak loads at all times, regardless of actual traffic.
Use a single instance for the application server and rely on the load balancer to distribute traffic evenly, without Auto Scaling.
Implement a manual scaling approach where instances are added or removed based on real-time monitoring by an administrator.
