Topic 1 Question 21
A company’s network engineer needs to design a new solution to help troubleshoot and detect network anomalies. The network engineer has configured Traffic Mirroring. However, the mirrored traffic is overwhelming the Amazon EC2 instance that is the traffic mirror target. The EC2 instance hosts tools that the company’s security team uses to analyze the traffic. The network engineer needs to design a highly available solution that can scale to meet the demand of the mirrored traffic. Which solution will meet these requirements?
- Deploy a Network Load Balancer (NLB) as the traffic mirror target. Behind the NLB. deploy a fleet of EC2 instances in an Auto Scaling group. Use Traffic Mirroring as necessary.
- Deploy an Application Load Balancer (ALB) as the traffic mirror target. Behind the ALB, deploy a fleet of EC2 instances in an Auto Scaling group. Use Traffic Mirroring only during non-business hours.
- Deploy a Gateway Load Balancer (GLB) as the traffic mirror target. Behind the GLB. deploy a fleet of EC2 instances in an Auto Scaling group. Use Traffic Mirroring as necessary.
- Deploy an Application Load Balancer (ALB) with an HTTPS listener as the traffic mirror target. Behind the ALB. deploy a fleet of EC2 instances in an Auto Scaling group. Use Traffic Mirroring only during active events or business hours.

  C) Makes more sense for the updated exam, GWLB is relatively new.
  
  Read the release post for GWLB - https://aws.amazon.com/about-aws/whats-new/2022/05/amazon-vps-traffic-mirroring-supports-sending-mirrored-traffic-gateway-load-balancer-backed-monitoring-appliances/ "This helps simplify the monitoring of network traffic across AWS accounts and VPCs in a highly scalable and operationally efficient manner by removing routing complexity and operational overhead."

  C This scenario is the typical use case for a Gateway Load Balancer. https://docs.aws.amazon.com/elasticloadbalancing/latest/gateway/introduction.html
