350-501 Automation and Assurance Practice Question
A service provider plans to deploy automation using Cisco NSO. Which two benefits does NSO provide for service lifecycle management? (Choose two.)
⚠ Common exam trap
Cisco often tests the distinction between NSO's centralized orchestration capabilities and features that belong to other tools (like monitoring or compliance), leading candidates to mistakenly select options that describe functions of separate Cisco products (e.g., Cisco DNA Center for compliance or Cisco ThousandEyes for monitoring).

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
✓
Automatic rollback on failed deployment.
Cisco NSO provides a built-in transaction management system that automatically rolls back a service deployment to its previous state if any part of the deployment fails. This ensures service lifecycle integrity by preventing partial or inconsistent configurations across devices.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Automatic rollback on failed deployment.
Why this is correct
NSO automatically rolls back changes if a deployment fails, ensuring device consistency.
- ✓
Multi-vendor device support via NETCONF and CLI.
Why this is correct
NSO uses NETCONF and CLI adapters to support a wide range of devices from different vendors.
- ✗
On-device scripting engine.
Why it's wrong here
On-device scripting is not a benefit of NSO; NSO uses service models to generate configuration without scripts on devices.
- ✗
Real-time traffic monitoring.
Why it's wrong here
Real-time traffic monitoring is not a function of NSO; it handles configuration and service lifecycle.
- ✗
Built-in configuration compliance checks.
Why it's wrong here
NSO does not have built-in compliance checks; these are typically added via packages or external tools.
