You are the network engineer at your company, and you are noticing issues with QoS in you’re the traffic to your instances hosting a VOIP program. You need to inspect the network packets to determine if it is a programming error or a networking error. How should you do this?
A. Configure a network monitoring program on every instance and stream the logs to an S3 bucket to be parsed.
B. Use CloudWatch
C. Set up another instance with an ENI added to act as a monitoring interface. Set the port to “promiscuous mode” and sniff the traffic to analyze the packets. Then output this single stream to an S3 bucket to be parsed.
D. Inspect Flow Logs
