350-501 Automation and Assurance Practice Question
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?
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
✓
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.
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 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.
- ✗
Increase the sensor-group period.
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.
