Question

A company wants to automate the orders processed on its website using API. The network device that supports the solution must:

Asoftware redundancy
BYANG data models
Cdistributed transactions
DXML encoding

Explanation

RESTCONF (RFC 8040) does not support distributed transactions - atomic operations that span multiple devices or datastores in a single transaction. NETCONF supports distributed transactions via its candidate datastore and commit/lock mechanisms. RESTCONF does support XML encoding (option D), YANG data models (option B), and software redundancy is handled at the device level, not the protocol level (option A). Because the solution requires distributed transactions, RESTCONF is unsuitable, and NETCONF would be the appropriate protocol.
