Implementing Automation for Cisco Service Provider Solutions (SPAUTO) — Question 41

What is an interior YANG data node that exists in at most one instance in the data tree and has no value?

Answer options

• A. listing node
• B. tree node
• C. container node
• D. leaf node

Correct answer: C

Explanation

The correct answer is C, as a container node serves as a grouping element in the data tree that can have child nodes but does not itself contain a value. The other options, such as listing node, tree node, and leaf node, either represent different structures or define nodes that can hold values or multiple instances.
