Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 374
A network engineer must configure a router for Flexible NetFlow IPFIX export. The IP address of the destination server is 172.17.12.1. The source address must be set to the Loopback0 IPv4 address and exported packets must be set to DSCP CS3. The TTL must be 64 and the transport protocol must be set to UDP with destination port 4739. Which configuration must the engineer apply to the router?
Answer options
- A. configure terminal flow exporter EXPORTER-1 destination 172.17.12.1 source Loopback0 dscp 3 ttl 64 export-protocol netflow-v9 transport udp 4739 end
- B. configure terminal flow exporter EXPORTER-1 destination 172.17.12.1 source Loopback0 dscp 24 ttl 64 export-protocol ipfix end
- C. configure terminal flow exporter EXPORTER-1 destination 172.17.12.1 source Loopback0 dscp 24 ttl 64 export-protocol netflow-v9 transport udp 4739 end
- D. configure terminal flow exporter EXPORTER-1 destination 172.17.12.1 source Loopback0 dscp 3 ttl 64 export-protocol ipfix end
Correct answer: B
Explanation
The correct answer is B as it specifies the export protocol as IPFIX and sets the source and destination correctly. Options A and D incorrectly set the DSCP value to 3 instead of 24, while option C incorrectly uses netflow-v9 instead of IPFIX as the export protocol.
