Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 283

Which feature must be configured before implementing NetFlow on a router?

Answer options

• A. syslog
• B. IP routing
• C. VRF
• D. SNMPv3

Correct answer: B

Explanation

IP routing must be enabled before NetFlow can be implemented on a router, as it allows the device to forward packets and collect flow data. Without IP routing, the router cannot track the flow of IP packets, making it impossible for NetFlow to function. The other options, such as syslog, VRF, and SNMPv3, are not prerequisites for NetFlow operation.
