CCNP Network Assurance Practice Question
A network engineer is using NetFlow to monitor traffic on a Cisco router. The engineer wants to export NetFlow data to a collector for analysis. Which two commands are required to configure NetFlow export on the router? (Choose two.)
⚠ Common exam trap
The trap here is thinking that enabling NetFlow on an interface is part of the export configuration; interface commands are separate from export commands.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
ip flow-export destination 192.168.1.100 2055
To export NetFlow data, the router must be configured with the destination collector address and port, and the export version. The ip flow-export destination command specifies where to send the data, and the ip flow-export version command specifies the format. These two commands are essential for the export process. Enabling NetFlow on interfaces is also needed, but that is not part of the export configuration commands.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
ip flow-export destination 192.168.1.100 2055
Why this is correct
The ip flow-export destination command specifies the IP address and port of the NetFlow collector. This is required to send NetFlow data to an external collector. Without this command, the router would not know where to export the flow records, so it is essential for NetFlow export configuration.
- ✓
ip flow-export version 9
Why this is correct
The ip flow-export version command sets the NetFlow export format version, such as version 9. This is necessary because the collector must understand the format. Different versions have different capabilities, and version 9 is commonly used for its flexibility. This command must be configured for export to work correctly.
- ✗
ip flow ingress
Why it's wrong here
The ip flow ingress command enables NetFlow accounting on an interface for ingress traffic. It is necessary to capture flow data, but it is applied to interfaces, not part of the export configuration. The question asks for export configuration commands, so this is not one of the required two.
- ✗
ip flow-cache timeout active 1
Why it's wrong here
The ip flow-cache timeout active command adjusts the active timeout for flow cache entries, controlling how long a flow is kept before being exported. While it can be useful for tuning, it is not required for basic NetFlow export. The default timeout is often sufficient, so this command is optional.
- ✗
ip flow-top-talkers
Why it's wrong here
The ip flow-top-talkers command is used to configure the top-talkers feature, which displays the highest volume flows. It is not required for exporting NetFlow data to a collector. It is an analysis tool on the router itself, not part of the export setup.
