- A
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' command controls how often the router re-sends the template to the collector, which is necessary because NetFlow v9 uses templates that may be lost.
- B
The router will wait 120 seconds before sending any flow data after the first template is sent.
Why wrong: The timeout controls template refresh, not the initial delay of data export.
- C
The router will export flow data only if the template has been successfully acknowledged by the collector within 120 seconds.
Why wrong: NetFlow v9 does not require acknowledgment; templates are sent unacknowledged.
- D
The router will store flow data for 120 seconds before exporting to allow batching.
Why wrong: The 'template data timeout' does not affect how long data is stored; that is controlled by cache timeouts.
Quick Answer
The answer is that the router will resend the NetFlow v9 template to the collector every 120 seconds to ensure the collector has the latest template. This command directly controls the template data timeout, which defines how often the exporter refreshes the template definition used to decode the variable-length NetFlow v9 records. Without periodic refreshes, the collector might lose the template due to timeout or fail to interpret new flows if the template changes, making this a critical parameter for reliable data export. On the Cisco CCNP ENARSI 300-410 exam, this concept tests your understanding of NetFlow v9 export mechanics, often appearing as a distractor where candidates confuse template timeout with flow cache timeout or active timer. A common trap is assuming a lower timeout improves performance, but in reality, it increases control traffic overhead. Memory tip: think of the template as a decoder ring—if you don’t send it regularly, the collector can’t read the message.
300-410 NetFlow and Flexible NetFlow Practice Question
This 300-410 practice question tests your understanding of netflow and flexible netflow. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?

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.
This question tests understanding of template refresh timing in NetFlow v9 export.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
