Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 248
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

A company needs to capture and log traffic for Nitro-based Amazon EC2 instances to comply with regulations. The company's network team has prepared a solution that enables VPC traffic mirroring and sends traffic to a second set of EC2 instances in an Auto Scaling group.

The network team has added a Network Load Balancer (NLB) in front of the EC2 instances the traffic will be sent to. However, the solution does not send any mirrored traffic to the EC2 instances that are behind the NLB.

How should the network team configure traffic mirroring to use the NLB endpoint?

  • A. Select the NLB as a source for traffic mirroring. Use a UDP listener.
  • B. Select the NLB as a target for traffic mirroring. Use a TCP listener and a UDP listener.
  • C. Select the NLB as a target for traffic mirroring. Use a TCP listener.
  • D. Select the NLB as a target for traffic mirroring. Use a UDP listener.

Selected Answer: D
Amazon VPC Traffic Mirroring allows you to capture and inspect network traffic from Nitro-based EC2 instances by sending mirrored traffic to a monitoring system. The mirrored traffic is always sent using UDP encapsulation. Since the Network Load Balancer (NLB) is being used as a target, the correct listener configuration should be UDP.
