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 applicat

Question

Options

• AAdd a Network Load Balancer in front of the EC2 instances.
• BConfigure an Auto Scaling group for the EC2 instances.
• CAdd an Application Load Balancer in front of the EC2 instances.
• DManually add more EC2 instances for the application.
• EAdd a Gateway Load Balancer in front of the EC2 instances.

• A
  82% (28)
• C
  12% (4)
• D
  3% (1)
• E
  3% (1)

Explanation

For an application requiring TCP communication and high availability: Network Load Balancer (NLB)is the best choice for load balancing TCP traffic because it is designed for handling high-throughput, low-latency connections. Auto Scaling groupensures that the application can automatically scale based on demand, adding or removing EC2 instances as needed, which is crucial for handling user growth. Option C (Application Load Balancer): ALB is primarily for HTTP/HTTPS traffic, not ideal for TCP. Option D (Manual scaling): Manually adding instances does not provide the automation or scalability required. Option E (Gateway Load Balancer): GLB is used for third-party virtual appliances, not for direct application load balancing.
