200-901 Cisco Platforms and Development Practice Question
An engineer is configuring IOS XE for RESTCONF. Which YANG module must be enabled to use RESTCONF?
⚠ Common exam trap
Cisco often tests the distinction between the protocol module (restconf) and the YANG data models (like Cisco-IOS-XE-native), leading candidates to confuse the data model with the enabling module.

Correct answer & explanation
✓
restconf
RESTCONF is a standardized protocol (RFC 8040) that uses HTTP methods to access data defined in YANG modules. To enable RESTCONF on IOS XE, the 'restconf' module must be explicitly enabled in the configuration, typically via the 'restconf' global command. Without this module, the RESTCONF server will not start, and HTTP requests to the RESTCONF API will fail.
