350-501 Automation and Quality of Services Practice Question

Which protocol is used by NSO to communicate with network devices for configuration management?

⚠ Common exam trap

Cisco often tests the distinction between management protocols (NETCONF) and monitoring protocols (SNMP/gRPC), leading candidates to confuse SNMP's widespread use with configuration capabilities.

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

✓

NETCONF

NSO (Network Services Orchestrator) uses NETCONF as its primary protocol for configuration management because NETCONF provides a standardized, transaction-based mechanism for editing device configurations using YANG data models. This allows NSO to perform atomic, rollback-capable configuration changes across multiple network devices, which is essential for service orchestration.
