Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 12

Which two uses of the YANG data modeling language are true? (Choose two.)

Answer options

• A. It can be used to model the configuration used by NETCONF operations.
• B. It can be used to access a device by HTTP.
• C. It can be used to replace the OSI model for troubleshooting.
• D. It can be used to shape state data of network elements.
• E. It can be used to replace RESTCONF as a mechanism to install and manipulate configuration.

Correct answer: A, D

Explanation

The correct answers are A and D because YANG is specifically designed to model configurations for NETCONF operations and to define state data of network elements. Options B, C, and E are incorrect as YANG does not provide access via HTTP, cannot replace the OSI model, and is not intended to replace RESTCONF.
