Exam 300-435 topic 1 question 15 discussion

I believe the answer is 3: If we take a look to the oficial Cisco Yang Model Library: https://github.com/YangModels/yang/tree/master/vendor/cisco/xe The below models do exist: Cisco-IOS-XE-native.yang Cisco-IOS-XE-ntp.yang Cisco-IOS-XE-ntp-oper.yang So somehow the NETCONF <get> must interact with them.

3 cause <get> will get both config and oper data - https://datatracker.ietf.org/doc/html/rfc6241

Leveraged Multiple AI to get to the bottom of this. There are 3 models referenced. Cisco-IOS-XE-native: Handles general native configurations. Cisco-IOS-XE-ntp: Manages NTP server configurations. Cisco-IOS-XE-ntp-oper: Deals with operational data for NTP.

The server section within the <native> element is not a separate model; it is part of the same YANG model. In the given XML, the <server> section is nested within the <native> model namespace, which means it is an extension or a component of the Cisco-IOS-XE-native YANG model. To clarify, here is the structure: Cisco-IOS-XE-native: This YANG model includes the <native> element and all its nested elements, including <ntp> and <server>. Cisco-IOS-XE-ntp-oper: This is a separate YANG model that deals with operational data related to NTP. Thus, the <get> operation interacts with these two distinct YANG models. The correct answer is: B. two

The questions says "model" not "module"...might that be the reason why the suggested answer is A (1) and not C (3) ?

C - 3 cause <get> will get both config and oper data

I think the provided answer is correct because the only "oper" module is NTP in that case.

3. Agreed. Check here: https://datatracker.ietf.org/doc/html/rfc6020 "All YANG definitions are specified within a module that is bound to a particular XML namespace [XML-NAMES], which is a globally unique URI [RFC3986]. A NETCONF client or server uses the namespace during XML encoding of data."

Can you please elaborate on why

I think it is C
