Topic 1 Question 987
2 つ選択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?
Add a Network Load Balancer in front of the EC2 instances.
Configure an Auto Scaling group for the EC2 instances.
Add an Application Load Balancer in front of the EC2 instances.
Manually add more EC2 instances for the application.
Add a Gateway Load Balancer in front of the EC2 instances.

This is A and B. TCP best option is NLB. I know tons of you want to use chat GPT and it's going to tell you application load balancer, then ask chatgpt if an application load balancer really is the best option for TCP and it will be like "aw dang dawg, its not, you're right". Then it will switch to A and B. Because chatgpt doesn't know everything. It's a great tool but you still need to research because it doesn't have all the answers.

TCP - NLB

ALB is much cheaper than the NLB. Thus, the best way to use NLB is when your application requires TCP and UDP connection. In this scenario, the users only communicate using TCP, which the ALB supports including variety of protocols such as, HTTP, HTTPS & SSL. Additionally, ALB's service uptime is up to 99.995%, which falls to the requirement of this question that application must be highly available.
