A. B. C. D.Answer - B.
NetFlow is a network protocol developed by Cisco for collecting IP traffic information and monitoring network traffic.
The AWS Documentation mentions the following.
VPC Flow Logs are similar to scheduled NetFlow/sFlow/IPFIX reports.
Flow logs collect the source and destination IP, source and destination ports, protocol, packet counts, and ALLOW or DENY action for a particular VPC, subnet, or ENI.
They are currently collected and sent as a report every 10 minutes.
Options A, C and D are all incorrect because the right software which matches the Netflow software is VPC Flow Logs.

AWS VPC Flow Logs can help meet the requirement of monitoring traffic between systems in an AWS environment. VPC Flow Logs capture information about the IP traffic going to and from network interfaces in an Amazon Virtual Private Cloud (VPC). This information can be used for network monitoring, troubleshooting, and security analysis.
When enabled, VPC Flow Logs can capture metadata about the traffic, including the source and destination IP addresses, ports, protocol, and packets and bytes transferred. The logs can be stored in Amazon S3 or CloudWatch Logs for analysis and long-term retention.
AWS CloudWatch Logs (option A) and AWS CloudWatch Metrics (option C) are useful for monitoring the performance and health of AWS resources, but they do not provide detailed information about network traffic.
AWS Config (option D) is a service that helps track resource inventory and changes in an AWS environment, but it does not provide network traffic monitoring capabilities.
In conclusion, AWS VPC Flow Logs is the most appropriate service for monitoring traffic between systems in an AWS environment, making it the correct answer to this question.
