A developer is writing a Python script to configure interface MTU on a Cisco IOS XE device using RESTCONF. The script needs to reference the correct data node in the YANG model. Which YANG construct would the interface MTU be represented as?

A container named 'mtu' inside the 'interface' container

A leaf named 'mtu' inside the 'interface' container

A leaf-list named 'mtu' inside the 'interface' container

A list named 'mtu' inside the 'interface' container

A network engineer is building a Python application that uses NETCONF to manage devices from two different vendors. Both vendors provide YANG modules that define a container named 'interface-config'. The engineer wants to use both modules in the same application. What is the correct way to reference the 'interface-config' container from each module in the NETCONF payload?

Use the module name as a prefix, such as 'vendor1-interface-config' and 'vendor2-interface-config'.

Use the module namespace as a prefix, such as 'vendor1:interface-config' and 'vendor2:interface-config'.

Rename the container in one module to 'interface-config-vendor2'.

Use the container name without any prefix, and rely on the NETCONF session to distinguish them.

A network team wants to automate the deployment of a new service that requires configuring multiple devices with a consistent set of parameters. They plan to use NETCONF with YANG models. What is the primary advantage of using YANG in this automation workflow?

YANG eliminates the need for any network protocol because it can directly configure devices.

YANG ensures that the automation script runs faster than using CLI commands.

YANG allows the automation script to use the same data model for all devices, regardless of vendor.

YANG automatically generates the Python code needed for the automation script.
