- A
Use SNMP traps to alert on each latency spike
Why wrong: SNMP traps are unsolicited notifications for immediate events, not suitable for collecting continuous historical data.
- B
Use SNMP polling with a suitable MIB to collect latency metrics at regular intervals
Polling gathers data at set intervals, which can be stored for trend analysis. This is the standard method for historical performance monitoring.
- C
Run a continuous ping test and manually log timestamps
Why wrong: Manual logging is inefficient and error-prone; automated monitoring is preferred.
- D
Use traceroute to identify each hop and measure latency per hop
Why wrong: Traceroute provides a snapshot of the path and per-hop latency but is not designed for continuous historical trend data.

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.
An NOC technician receives an alert that latency on a critical WAN link has increased significantly. The technician needs to analyze the latency trend over the past week to identify patterns. Which approach is the most efficient for gathering this historical data?
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
✓
Use SNMP polling with a suitable MIB to collect latency metrics at regular intervals
SNMP polling with a suitable MIB (e.g., IF-MIB for interface statistics or IP-MIB for performance metrics) allows the NOC to collect latency data at regular, configurable intervals over time. This historical data can be stored in a management system and analyzed for trends, making it the most efficient method for identifying patterns in WAN latency over a week. SNMP traps, by contrast, are event-driven and do not provide the continuous, periodic data needed for trend 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.
- ✗
Use SNMP traps to alert on each latency spike
Why it's wrong here
SNMP traps are unsolicited notifications for immediate events, not suitable for collecting continuous historical data.
When this WOULD be correct
A question asking for the best method to receive real-time alerts for critical latency spikes, where immediate notification is required and historical analysis is not needed.
- ✓
Use SNMP polling with a suitable MIB to collect latency metrics at regular intervals
Why this is correct
Polling gathers data at set intervals, which can be stored for trend analysis. This is the standard method for historical performance monitoring.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Run a continuous ping test and manually log timestamps
Why it's wrong here
Manual logging is inefficient and error-prone; automated monitoring is preferred.
When this WOULD be correct
This approach would be correct if the question asked for a real-time, ad-hoc latency check on a specific link without any monitoring infrastructure, and the technician only needed a few minutes of data.
- ✗
Use traceroute to identify each hop and measure latency per hop
Why it's wrong here
Traceroute provides a snapshot of the path and per-hop latency but is not designed for continuous historical trend data.
When this WOULD be correct
A technician needs to identify which specific hop along a WAN path is introducing the highest latency during a current performance issue. Traceroute would be the correct tool to isolate the problematic hop in real time.
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.
✓Use SNMP polling with a suitable MIB to collect latency metrics at regular intervalsCorrect answer▾
Why this is correct
Polling gathers data at set intervals, which can be stored for trend analysis. This is the standard method for historical performance monitoring.
✗Use SNMP traps to alert on each latency spikeWrong answer — click to see why▾
Why this is wrong here
SNMP traps are event-driven notifications for immediate alerts, not designed for gathering historical trend data over a week. They would not provide the regular interval data needed to analyze latency patterns.
★ When this WOULD be the correct answer
A question asking for the best method to receive real-time alerts for critical latency spikes, where immediate notification is required and historical analysis is not needed.
Why candidates choose this
Candidates may confuse SNMP traps with SNMP polling, thinking traps can also be used for data collection, or they may focus on the 'alert' aspect of the question without considering the need for historical trend analysis.
✗Run a continuous ping test and manually log timestampsWrong answer — click to see why▾
Why this is wrong here
Continuous ping and manual logging is inefficient for analyzing a week-long latency trend, as it requires constant human intervention and does not provide automated, structured historical data.
★ When this WOULD be the correct answer
This approach would be correct if the question asked for a real-time, ad-hoc latency check on a specific link without any monitoring infrastructure, and the technician only needed a few minutes of data.
Why candidates choose this
Candidates may think ping is a simple and direct way to measure latency, and manual logging seems like a straightforward method to collect data without needing to configure SNMP or MIBs.
✗Use traceroute to identify each hop and measure latency per hopWrong answer — click to see why▾
Why this is wrong here
Traceroute measures per-hop latency at a single point in time, not historical trends over a week. It is inefficient for gathering continuous historical data and does not provide a consolidated latency trend.
★ When this WOULD be the correct answer
A technician needs to identify which specific hop along a WAN path is introducing the highest latency during a current performance issue. Traceroute would be the correct tool to isolate the problematic hop in real time.
Why candidates choose this
Candidates may think traceroute provides detailed path information and assume it can be used repeatedly to build a trend, but they overlook that it is not designed for automated, scheduled historical data collection.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse SNMP traps (event-driven alerts) with SNMP polling (periodic data collection), assuming traps can provide historical trend data when they are designed only for real-time notifications.
Detailed technical explanation
How to think about this question
SNMP polling works by sending GET requests to a network device's MIB (Management Information Base), which contains OIDs (Object Identifiers) like ifInOctets or ipNetToMediaPhysAddress. For latency, a common approach is to poll the device's ICMP echo response time via a custom MIB or use the device's own latency statistics (e.g., from a performance monitoring MIB like RFC 2925). In real-world NOCs, this data is fed into a time-series database (e.g., Prometheus or InfluxDB) to generate graphs and detect anomalies, such as latency spikes during business hours.
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.
