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.
Question
What is a benefit of YANG modules?
Options
- Atightly coupled models with encoding to improve performance
- Beasier multivendor interoperability provided by common or industry models
- Cavoidance of ecosystem fragmentation by having fixed modules that cannot be changed
- Dsingle protocol and model coupling to simplify maintenance and support
Explanation
YANG modules enhance multivendor interoperability by providing common or industry-standard data models, enabling devices from different vendors to be managed and configured consistently.
Common mistakes.
- A. YANG models are generally designed to be independent of specific encoding (like XML or JSON) for flexibility, not tightly coupled for performance.
- C. YANG modules are designed to be extensible and can be augmented, not fixed, to allow for vendor-specific features while maintaining interoperability.
- D. YANG models are designed to be protocol-agnostic, working with NETCONF and RESTCONF, not coupled to a single protocol.
