Question

A company recently launched a new application for its customers. The application runs on multiple Amazon EC2 instances across two Availability Zones. End users use TCP to communicate with the application. The application must be highly available and must automatically scale as the number of users increases. Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

Accepted Answer

Correct answer: A, B. The correct answer is A, B. Option A: Add a Network Load Balancer in front of the EC2 instances. Option B: Configure an Auto Scaling group for the EC2 instances. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. A Network Load Balancer handles very high throughput TCP/UDP traffic with ultra-low latency and static IPs. This option delivers the requirement at the lowest cost.
