What is an advantage of utilizing data models in a multivendor environment?

Data models primarily standardize data representation and do not inherently lower the CPU load on managed devices; CPU load is more dependent on the device's hardware, software implementation, and the specific management protocol used.

While some protocols that utilize data models (like NETCONF) can be secured (e.g., via SSH), the primary advantage of data models themselves is their structured representation of data, not directly improving communication security or mandating binary encoded protocols.

Utilizing data models, such as YANG, in a multivendor environment facilitates a unified approach to configuration and management by providing a common, standardized language and structure for network device data, allowing for consistent automation and tooling across different vendor platforms.

Data models, specifically YANG, explicitly define and maintain a clear distinction between configuration data (the intended state) and operational state data (the current state), which is a design feature for robust network management, not something that is removed.
