200-901 Infrastructure and Automation Practice Question
Which tool is specifically designed for model-driven programmability using YANG data models?
⚠ Common exam trap
Cisco often tests the distinction between a protocol that natively uses YANG (NETCONF) versus tools that can work with YANG but are not designed specifically for it (like Ansible), so the trap here is assuming any automation tool that supports YANG qualifies as 'specifically designed' for model-driven programmability.

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
NETCONF is the correct answer because it is a network management protocol specifically designed to operate with YANG data models, using XML or JSON encoding to transport configuration and state data. YANG defines the structure of the data, and NETCONF provides the operations (get, edit-config, etc.) to manipulate that data in a model-driven, programmatic way. This makes NETCONF the standard tool for model-driven programmability in modern network automation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
NETCONF
Why this is correct
NETCONF is a protocol designed for model-driven management with YANG.
- ✗
SNMP
Why it's wrong here
SNMP is an older protocol, not model-driven with YANG.
- ✗
CLI
Why it's wrong here
CLI is command-line interface, not model-driven.
- ✗
Ansible
Why it's wrong here
Ansible is an automation tool that can use YANG but is not specifically designed for it.
