300-410 Practice Question: Consider the following partial configuration on…
Consider the following partial configuration on router R6:
flow exporter EXPORTER-3 destination 192.168.2.200 source Loopback0 transport udp 2055 template data timeout 120 ! flow monitor MONITOR-6 exporter EXPORTER-3 record netflow ipv4 original-input !
interface GigabitEthernet0/6 ip flow monitor MONITOR-6 input
!
What is the effect of the 'template data timeout 120' command?
⚠ Common exam trap
Many exam-takers confuse the template refresh timer with flow cache/active timeouts or with a reliability/ACK mechanism — candidates often assume UDP NetFlow has acknowledgments or that the timer delays data export.

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
✓
The router will resend the NetFlow v9 template to the collector every 120 seconds to ensure the collector has the latest template.
The 'template data timeout 120' command under the flow exporter configuration sets the refresh interval for NetFlow v9 (or IPFIX) templates to 120 seconds. Because NetFlow v9/IPFIX templates are sent periodically (not on every packet), the exporter re-transmits the template to the collector every 120 seconds so the collector can continue to decode flow records even if it missed the initial template or restarted. This ensures template freshness and collector synchronization.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The router will resend the NetFlow v9 template to the collector every 120 seconds to ensure the collector has the latest template.
Why this is correct
The template data timeout sets the resend interval for NetFlow v9 template records on the exporter. Every 120 seconds the router retransmits the template to 192.168.2.200:2055, ensuring the collector can decode subsequent flow records even after a restart.
- ✗
The router will wait 120 seconds before sending any flow data after the first template is sent.
Why it's wrong here
The timer governs periodic re-export of the template record, not a delay before flow data; data records are exported as flows expire, immediately after the initial template. It is tempting because a timeout sounds like a wait period, but the correct mechanism is template refresh, and a delay would require a different command.
- ✗
The router will export flow data only if the template has been successfully acknowledged by the collector within 120 seconds.
Why it's wrong here
The command sets the resend interval for template packets on the exporter, not a collector-acknowledgement gate; NetFlow over UDP has no acknowledgement mechanism, so flow export proceeds regardless. It is tempting because template refresh and collector receipt are related, but acknowledgement applies to reliable transports such as SCTP, not UDP 2055.
- ✗
The router will store flow data for 120 seconds before exporting to allow batching.
Why it's wrong here
The command controls how often the template is resent to the collector, not local buffering of flow records; flow data is exported as flows age out, independent of this timer. It is tempting because batching sounds like a timeout function, but caching is governed by the active/inactive timeout values in the flow record.
