What is a benefit of YANG modules?
The correct answer is B. easier multivendor interoperability provided by common or industry models. YANG modules enhance multivendor interoperability by providing common or industry-standard data models, enabling devices from different vendors to be managed and configured consistently.

Why each option
YANG modules enhance multivendor interoperability by providing common or industry-standard data models, enabling devices from different vendors to be managed and configured consistently.
YANG models are generally designed to be independent of specific encoding (like XML or JSON) for flexibility, not tightly coupled for performance.
YANG (Yet Another Next Generation) is a data modeling language used to model configuration and state data for network devices, enabling devices from different vendors to understand and communicate using a common language, thereby improving multivendor interoperability. Industry-standard YANG models, such as those from OpenConfig or IETF, promote a unified approach to network management across diverse hardware.
YANG modules are designed to be extensible and can be augmented, not fixed, to allow for vendor-specific features while maintaining interoperability.
YANG models are designed to be protocol-agnostic, working with NETCONF and RESTCONF, not coupled to a single protocol.
