Selected Answer: B

Agree with B. A. optional metrics doesn't exist in yang (the name is not being used) B. Correct, everything ending with * is a list. Lists with a type are leaf-lists. So where interface* [name] is a list, higher-layer-if and lower-layer-if are leaf-lists. C. incorrect, not even close to being possible D. Containers -> "a container node has at most one instance", in this example interfaces and statistics are containers. that makes two, not three. found this very helpful : https://www.tail-f.com/wordpress/wp-content/uploads/2014/02/Tail-f-Instant-YANG.pdf
