Question

A company hosts an application on Amazon EC2 instances that run in a single Availability Zone. The application is accessible by using the transport layer of the Open Systems Interconnection (OSI) model. The company needs the application architecture to have high availability. Which combination of steps will meet these requirements MOST cost-effectively? (Choose two.)

Accepted Answer

Correct answer: B, D. The correct answer is B, D. Option B: Configure a Network Load Balancer in front of the EC2 instances. Option D: Create an Auto Scaling group for the EC2 instances. Configure the Auto Scaling group to use multiple Availability Zones. Configure the Auto Scaling group to run application health checks on the 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.
