Which combination of steps will meet these requirements MOST cost-effectively?
(Choose two.)
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.
Explanations:
A Network Load Balancer (NLB) is ideal for handling TCP traffic and provides high availability and scalability by distributing incoming traffic across EC2 instances.
Configuring an Auto Scaling group ensures that the application can automatically scale based on demand, maintaining high availability and cost-efficiency.
An Application Load Balancer (ALB) is designed for HTTP and HTTPS traffic, not TCP, and is therefore not appropriate for this scenario.
Manually adding more EC2 instances does not provide automation or scalability and can lead to higher operational costs.
A Gateway Load Balancer is designed for special use cases such as integrating third-party appliances, not for distributing TCP traffic across EC2 instances.
