- A
Use a packet capture on the network to identify drops.
Why wrong: Packet capture is network-wide and would require filtering to identify specific routers; it is inefficient for 5000 devices.
- B
Enable telemetry debugging on each router and review logs.
Why wrong: Debugging generates excessive data and is not practical for 5000 routers; it would also affect performance.
- C
Check the telemetry subscription statistics on each router for drops and errors.
Routers maintain per-subscription counters (e.g., sent packets, dropped packets, sequence errors) that directly pinpoint problematic devices.
- D
Configure a second collector on a different port and split the routers across two collectors.
Why wrong: This would reduce load but not identify which routers are dropping data; it does not isolate the problem.
Quick Answer
The answer is to check the telemetry subscription statistics on each router for drops and errors. This is correct because model-driven telemetry relies on gRPC dial-out subscriptions, and the show telemetry statistics command provides per-router counters for sequence gaps, packet drops, and encoding errors, directly isolating which devices are losing data. On the Cisco SPCOR 350-501 exam, this scenario tests your ability to differentiate between network-wide diagnostics and router-level telemetry verification; a common trap is to focus on collector load balancing or network congestion first, but the engineer must identify individual routers with telemetry data loss before troubleshooting the path. Remember that telemetry subscriptions are stateful per router, so checking statistics at the source is the fastest way to pinpoint the problem. A useful memory tip: “Stats at the source stop the guesswork”—always verify subscription health on the router itself before blaming the network.
350-501 Automation and Assurance Practice Question
This 350-501 practice question tests your understanding of automation and assurance. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 large SP is using model-driven telemetry to collect interface statistics from 5000 routers to a centralized collector. The collector is deployed on two servers with load balancing. Recently, the operations team noticed that some router telemetry streams are missing data for intervals of up to 5 minutes during peak hours. The engineer suspects packet loss between the routers and collector. The routers are sourced from different vendors but all support gRPC dial-out telemetry. The engineer wants to identify which routers are affected. The current configuration uses a single telemetry collector IP with port 5000. What step should the engineer take to isolate the problematic routers?
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
Check the telemetry subscription statistics on each router for drops and errors.
Checking telemetry subscription statistics on each router (e.g., using show telemetry statistics) provides per-router counters for drops, errors, and sequence gaps. This directly identifies which routers are experiencing loss. Other options are either too manual, network-wide, or do not isolate individual routers.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
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 350-501 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.
