ANS-C01 Question 143

Question

A company has an application that runs on a fleet of Amazon EC2 instances. A new company regulation mandates that all network traffic to and from the EC2 instances must be sent to a centralized third-party EC2 appliance for content inspection. Which solution will meet these requirements?
A. Configure VPC flow logs on each EC2 network interface. Publish the flow logs to an Amazon S3 bucket. Create a third-party EC2 appliance to acquire flow logs from the S3 bucket. Log in to the appliance to monitor network content.
B. Create a third-party EC2 appliance in an Auto Scaling group fronted by a Network Load Balancer (NLB). Configure a mirror session. Specify the NLB as the mirror target. Specify a mirror filter to capture inbound and outbound traffic. For the source of the mirror session, specify the EC2 elastic network interfaces for all the instances that host the application.
C. Configure a mirror session. Specify an Amazon Kinesis Data Firehose delivery stream as the mirror target. Specify a mirror filter to capture inbound and outbound traffic. For the source of the mirror session, specify the EC2 elastic network interfaces for all the instances that host the application. Create a third-party EC2 appliance. Send all traffic to the appliance through the Kinesis Data Firehose delivery stream for content inspection.
D. Configure VPC flow logs on each EC2 network interface. Send the logs to Amazon CloudWatch. Create a third-party EC2 appliance. Configure a CloudWatch filter to send the flow logs to Amazon Kinesis Data Firehose to load the logs into the appliance.
