Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 561

What is a benefit of YANG modules?

Answer options

• A. tightly coupled models with encoding to improve performance
• B. easier multivendor interoperability provided by common or industry models
• C. avoidance of ecosystem fragmentation by having fixed modules that cannot be changed
• D. single protocol and model coupling to simplify maintenance and support

Correct answer: B

Explanation

The correct answer is B because YANG modules promote easier interoperability across different vendors by utilizing common models that are widely accepted. The other options present misconceptions; A suggests a performance improvement that is not the primary benefit, C incorrectly implies that fixed modules reduce fragmentation, and D suggests that maintenance is simplified solely through protocol coupling, which is not the main advantage of YANG.
