350-501 Automation and Quality of Service Practice Question
A network automation engineer needs to retrieve QoS policy statistics from a Cisco IOS XE device using RESTCONF. Which YANG module should be targeted?
⚠ Common exam trap
Cisco often tests the distinction between native Cisco YANG modules (like Cisco-IOS-XE-QoS) and open-standard models (like ietf-qos or openconfig-qos), expecting candidates to know that native modules are required for platform-specific features and statistics on IOS XE devices.

Correct answer & explanation
✓
Cisco-IOS-XE-QoS
The Cisco-IOS-XE-QoS YANG module is the native Cisco module that provides the data model for QoS policy configuration and operational statistics on IOS XE devices. Since the engineer is using RESTCONF to retrieve QoS statistics from a Cisco IOS XE device, this module is the correct target because it is specifically designed for and supported on IOS XE platforms.
