What information does VPC Flow Logs provide?

What information does VPC Flow Logs provide?

• A. Only the number of packets sent and received
• B. Source and destination IP addresses, ports, and protocols
• C. Only the amount of data transferred
• D. Real-time monitoring of network performance

Answer: (B)

VPC Flow Logs provide valuable insights into the traffic going to and from network interfaces in your Virtual Private Cloud (VPC). The correct response highlights that Flow Logs capture detailed attributes of each network flow, including the source and destination IP addresses, ports, and protocols used in the communication. This information is critical for troubleshooting network issues, analyzing traffic patterns, understanding security postures, and ensuring compliance. For instance, by analyzing source and destination IP addresses, you can identify potential malicious traffic or unauthorized access attempts. Ports indicate which services are being accessed or attempted, while the protocols tell you whether the communication uses TCP, UDP, or another protocol, which is important for deeper network analysis and performance optimization. Understanding this comprehensive set of data allows architects and administrators to maintain better control over their network and ensure it is secure and functioning as intended. Other options do not encompass the breadth of information that Flow Logs provide, focusing instead on narrower aspects.
