The answer is to enable on-change reporting with suppression. This MDT subscription parameter reduces the telemetry data rate by transmitting updates only when a monitored value actually changes, and the suppression mechanism prevents excessively frequent updates for rapidly fluctuating metrics, thereby lowering the CPU load on the gRPC receiver without losing critical threshold events. On the Cisco SPCOR / CCNP Service Provider Core 350-501 exam, this concept tests your understanding of model-driven telemetry tuning, often appearing in scenario-based questions where an engineer must balance data granularity against receiver performance. A common trap is to increase the sample interval, but that risks missing transient threshold events entirely. Remember the memory tip: “Change with a cap” — on-change reporting sends the change, and suppression caps the rate.
350-501 Automation and Assurance Practice Question
This 350-501 practice question tests your understanding of automation and assurance. 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 SP engineer is configuring model-driven telemetry (MDT) to monitor interface utilization on Cisco routers. The telemetry receiver uses gRPC and is experiencing high CPU load due to excessive subscription data. Which MDT subscription parameter should be adjusted to reduce the data rate without losing critical threshold events?
Why wrong: A smaller path reduces the amount of data collected but not necessarily the rate; it may still cause high load if sampling is periodic.
B
Increase the sensor-group period.
Why wrong: Increasing the period is similar to increasing sample-interval, risking missed events.
C
Increase the sample-interval.
Why wrong: Increasing sample-interval reduces data rate but may cause threshold events in between samples to be missed.
D
Enable on-change reporting with suppression.
On-change reporting sends updates only when the value changes, and suppression limits the update frequency, reducing load while still reporting events.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable on-change reporting with suppression.
On-change reporting with suppression reduces data rate by sending updates only when values change, and suppression prevents too-frequent updates. Increasing sample interval risks missing threshold events. Other options do not effectively reduce data rate while preserving event detection.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Use a smaller path XPath.
Why it's wrong here
A smaller path reduces the amount of data collected but not necessarily the rate; it may still cause high load if sampling is periodic.

Why it's wrong here
Increasing the period is similar to increasing sample-interval, risking missed events.
✗
Increase the sample-interval.
Why it's wrong here
Increasing sample-interval reduces data rate but may cause threshold events in between samples to be missed.
✓
Enable on-change reporting with suppression.
Why this is correct
On-change reporting sends updates only when the value changes, and suppression limits the update frequency, reducing load while still reporting events.

Static NAT maps one inside address to one outside address.
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.
