200-901 Cisco Platforms and Development Practice Question
When using RESTCONF on Cisco IOS XE, which URL retrieves the hostname configuration?
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
✓
GET /restconf/data/Cisco-IOS-XE-native:native/hostname
The native YANG model Cisco-IOS-XE-native contains the hostname under /native/hostname.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
GET /restconf/data/ietf-interfaces:interfaces
Why it's wrong here
The ietf-interfaces model describes interface entries only; it carries no hostname leaf. It is tempting because IETF YANG modules are standardised and portable, but the correct retrieval targets the Cisco-IOS-XE-native hostname node, which this path does not reach.
- ✗
GET /restconf/data/openconfig-interfaces:interfaces
Why it's wrong here
The openconfig-interfaces model exposes interface state and configuration, not the device hostname. It is tempting because OpenConfig paths are vendor-neutral and widely used, but hostname is not defined within that model, so this URL returns interface data instead.
- ✗
GET /restconf/data/Cisco-IOS-XE-native:native/interface
Why it's wrong here
This path addresses the interface container, returning interface configuration rather than the hostname leaf. It is tempting because Cisco-IOS-XE-native is the correct native model, but the hostname resides under the native/hostname node, so the interface branch returns unrelated data.
- ✓
GET /restconf/data/Cisco-IOS-XE-native:native/hostname
Why this is correct
RESTCONF exposes the native data model at /restconf/data/, and the hostname leaf sits under the Cisco-IOS-XE-native:native container. A GET on that exact path returns the configured hostname, matching the YANG-modelled URL structure IOS XE publishes.
