A network engineer is using RESTCONF to manage a Cisco IOS XE device. The engineer sends a GET request to retrieve the configuration of a specific interface, but receives a 405 Method Not Allowed error. The engineer has verified that the URI is correct and that the device supports RESTCONF. What is the most likely cause of this error?

The device does not support HTTPS.

The engineer is using the wrong content type in the Accept header.

The device's YANG model is not loaded.

The URI points to a resource that does not support the GET method, such as an RPC or operation resource.

What is a primary benefit of model-driven programmability compared to traditional CLI-based configuration on Cisco devices?

It automatically optimizes network performance without any human intervention.

It provides a structured, standardized way to represent and manage device configuration and state data.

It eliminates the need for network administrators to understand device configuration syntax.

It requires the use of a specific vendor's proprietary API for all network devices.
