300-410 Practice Question: Consider the following partial configuration on…
Consider the following partial configuration on router R4:
flow exporter EXPORTER-2 destination 10.10.10.1 source Loopback0 transport udp 9996 option interface-table option sampler-table ! flow monitor MONITOR-4 exporter EXPORTER-2 record netflow ipv4 original-input !
interface GigabitEthernet0/4 ip flow monitor MONITOR-4 input
!
What is the purpose of the 'option interface-table' and 'option sampler-table' commands under the exporter?
⚠ Common exam trap
Candidates often confuse the export of metadata with the configuration of sampling itself; candidates often think 'option sampler-table' enables sampling, but it only exports sampler information.

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
✓
They instruct the router to periodically export metadata about interfaces and samplers to the collector, aiding in data interpretation.
The 'option interface-table' and 'option sampler-table' commands under a flow exporter enable the periodic export of metadata about interfaces and samplers to the NetFlow collector. This metadata is sent as separate option template records, allowing the collector to correctly interpret flow records that reference interface indices or sampler IDs. Without these options, the collector would receive flow data but lack the mapping to resolve interface names or sampling parameters, reducing the usefulness of the exported flows.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
They instruct the router to periodically export metadata about interfaces and samplers to the collector, aiding in data interpretation.
Why this is correct
These options make the exporter send periodic metadata records describing interface names and sampler configuration to the collector. Without them, the collector receives flow records referencing interface or sampler IDs it cannot resolve, hindering interpretation.
- ✗
They enable the router to sample traffic based on interface and sampler tables before exporting.
Why it's wrong here
These options export metadata describing interfaces and samplers; they do not configure sampling itself, which is set by a sampler applied under the flow monitor or interface. It is tempting because 'sampler-table' implies sampling configuration. They are correct when the collector needs sampler IDs to interpret already-sampled flow records.
- ✗
They limit the export to only interface and sampler statistics, ignoring flow records.
Why it's wrong here
These options add interface and sampler metadata tables alongside flow records, not instead of them; the monitor still exports netflow ipv4 original-input records. It is tempting because the word 'option' suggests a filter. They are the correct choice when a collector needs interface names and sampler IDs to interpret exported flows.
- ✗
They are required for the exporter to function; without them, no data is exported.
Why it's wrong here
The exporter functions without these options; they add supplementary metadata tables that a collector may request, and flows still export if omitted. It is tempting because missing tables can cause incomplete decoding at the collector, which looks like failure. They are correct when the collector requires interface or sampler mapping data.
