Understanding the netflow ipv4 original-input Record

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 R2:

flow exporter EXPORTER-1 destination 192.168.1.100 source Loopback0 transport udp 2055 ! flow monitor MONITOR-2 exporter EXPORTER-1 record netflow ipv4 original-input cache timeout active 30 !

interface GigabitEthernet0/2
 ip flow monitor MONITOR-2 input

!

What is the effect of this configuration?

Quick Answer

The answer is that the router will export NetFlow version 9 records containing IPv4 source and destination addresses, protocol, and packet/byte counts. This is because the predefined record `netflow ipv4 original-input` instructs the flow monitor to capture the standard seven key fields—source IP, destination IP, source port, destination port, protocol, ToS, and input interface—along with essential counters like packets and bytes, all exported via the configured exporter using NetFlow version 9. On the Cisco CCNP ENARSI 300-410 exam, this configuration tests your understanding of how predefined records simplify flow monitoring; a common trap is confusing `original-input` with `original-output`, which would instead capture egress flow data. Remember that `original-input` always refers to the direction of traffic as it enters the interface, not the direction of the exported flow. A helpful memory tip: “Input is Incoming—it captures what hits the interface first.”

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

The router will export NetFlow version 9 records containing IPv4 source and destination addresses, protocol, and packet/byte counts.

This question tests knowledge of the 'record netflow ipv4 original-input' predefined record and its behavior.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 export NetFlow version 9 records containing IPv4 source and destination addresses, protocol, and packet/byte counts.

    Why this is correct

    The record 'netflow ipv4 original-input' is a predefined Flexible NetFlow record that matches traditional NetFlow fields (source/destination IP, protocol, etc.) and exports them in NetFlow v9 format.

    Related concept

    Read the scenario before looking for a memorised answer.

  • The router will export NetFlow version 5 records because the exporter uses UDP port 2055.

    Why it's wrong here

    The record type determines the export format; 'netflow ipv4 original-input' uses NetFlow v9, not v5. The UDP port does not dictate the version.

  • The flow monitor will only collect traffic on the input direction of GigabitEthernet0/2, but no export will occur because the exporter is not applied to the monitor.

    Why it's wrong here

    The exporter is correctly applied under the flow monitor configuration with the 'exporter EXPORTER-1' command.

  • The flow monitor will export flows every 30 seconds only if the flow is idle for that period.

    Why it's wrong here

    The 'cache timeout active 30' exports active flows every 30 seconds, not idle flows.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Trap categories for this question

  • Command / output trap

    The exporter is correctly applied under the flow monitor configuration with the 'exporter EXPORTER-1' command.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
