- A
SNMP
Why wrong: SNMP is used for polling device statistics but not for exporting detailed flow data like conversations between endpoints.
- B
NetFlow
Correct. NetFlow is a protocol that captures and exports IP traffic flow information, including source/destination, ports, and byte counts, to a collector for analysis.
- C
ICMP
Why wrong: ICMP is used for error reporting and diagnostic functions like ping, not for flow data export.
- D
LLDP
Why wrong: LLDP is used for neighbor discovery and device information exchange, not for traffic flows.
Question 416 of 520
N10-009 Network Operations Practice Question
This N10-009 practice question tests your understanding of network operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A network administrator needs to collect traffic flow data from routers and switches to analyze bandwidth usage patterns. Which protocol should be implemented on the devices to export flow data to a collector?
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
✓
NetFlow
NetFlow (or its standards-based equivalent, IPFIX) is the correct protocol because it is specifically designed to export traffic flow metadata—such as source/destination IPs, ports, and byte counts—from routers and switches to a collector for bandwidth usage analysis. SNMP can poll interface counters but does not provide per-flow granularity, making NetFlow the appropriate choice for detailed traffic pattern analysis.
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.
- ✗
SNMP
Why it's wrong here
SNMP is used for polling device statistics but not for exporting detailed flow data like conversations between endpoints.
When this WOULD be correct
A network administrator needs to monitor the CPU utilization and interface errors on routers and switches. SNMP would be the correct protocol to poll these metrics from the devices.
- ✓
NetFlow
Why this is correct
Correct. NetFlow is a protocol that captures and exports IP traffic flow information, including source/destination, ports, and byte counts, to a collector for analysis.

LLDP
Why it's wrong here
LLDP is used for neighbor discovery and device information exchange, not for traffic flows.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The N10-009 exam frequently reuses these exact scenarios with slightly different constraints.
✓NetFlowCorrect answer▾
Why this is correct
Correct. NetFlow is a protocol that captures and exports IP traffic flow information, including source/destination, ports, and byte counts, to a collector for analysis.
✗SNMPWrong answer — click to see why▾
Why this is wrong here
SNMP is used for monitoring and managing network devices by polling MIB variables, not for exporting traffic flow data. It lacks the ability to provide detailed per-flow information like source/destination IPs and ports.
★ When this WOULD be the correct answer
A network administrator needs to monitor the CPU utilization and interface errors on routers and switches. SNMP would be the correct protocol to poll these metrics from the devices.
Why candidates choose this
Candidates may confuse SNMP's monitoring capabilities with flow data collection, as both involve network management and data gathering.
✗ICMPWrong answer — click to see why▾
Why this is wrong here
ICMP is used for network diagnostics (e.g., ping, traceroute) and does not export traffic flow data for bandwidth usage analysis.
★ When this WOULD be the correct answer
When the question asks for a protocol to test network connectivity or measure round-trip time between devices, ICMP would be correct.
Why candidates choose this
Candidates may confuse ICMP's role in network monitoring with flow data collection, assuming any 'monitoring' protocol works for bandwidth analysis.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse SNMP's ability to poll interface bandwidth utilization with the need for per-flow granularity, leading them to choose SNMP instead of recognizing that NetFlow is the dedicated protocol for exporting flow data.
Detailed technical explanation
How to think about this question
NetFlow operates by caching flow records on the device based on a 7-tuple key (e.g., IPs, ports, protocol), then exporting them via UDP (typically port 2055) to a collector. A subtle behavior is that NetFlow sampling (e.g., 1:1000) can be configured on high-throughput links to reduce CPU load, but this introduces statistical inaccuracies that must be accounted for in bandwidth analysis. In real-world scenarios, engineers often use NetFlow v9 or IPFIX for flexible template-based exports, allowing custom fields like MPLS labels or application IDs.
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.
TExam Day Tips
- 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 N10-009 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.
