350-501 Automation and Assurance Practice Question
A network engineer is using Cisco NSO to create a managed L3VPN service. After deploying the service, the engineer notices that the configuration on the devices is not being updated. What is the most likely cause?
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
✓
The service has not been committed.
In NSO, services are committed to push configuration changes to devices. If the commit is not performed, the changes remain in the candidate database and are not applied. Other options are less likely given the symptom.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The service model is not compiled.
Why it's wrong here
An uncompiled model would prevent service creation, not just device update failure after deployment.
- ✓
The service has not been committed.
Why this is correct
In NSO, commit is required to push the configuration to devices; without it, the configuration remains in the candidate.
- ✗
The device is not in the device list.
Why it's wrong here
If the device were not in the list, the service deployment would likely fail with an error, not silently not update.
- ✗
The sync-from command was not run.
Why it's wrong here
Sync-from is used to pull device configurations into NSO, not to push changes.
