NetFlow data is commonly used to collect and analyze traffic flow data. Which option describes this use?

• A. To encrypt all traffic
• B. To manage user accounts
• C. To collect and analyze traffic flow data
• D. To store files in the cloud

Answer: (C)

NetFlow is used to collect and analyze traffic flow data by exporting flow records from routers and switches. These records summarize each communication between endpoints, including source and destination IPs, ports, protocol, and counters like bytes and packets, often with timestamps. This flow-level metadata lets network operators see who is talking to whom, how much data is being exchanged, and when, enabling traffic pattern analysis, capacity planning, performance monitoring, and anomaly detection. It doesn’t encrypt payloads, so it isn’t used for securing traffic; it isn’t about managing user accounts, and it isn’t for storing files in the cloud.
