A YANG module is being written to model both the configured and the operational state of a routing protocol. The engineer wants the configured parameters to be writable, while the operational statistics should be read-only. Which approach correctly distinguishes these?

Place the configured parameters in a container with 'config true;' and the operational statistics in a separate container with 'config false;'.

Place all leaves in a single container and rely on the client to know which are writable.

Use a leaf-list for the configured parameters and a container for the operational statistics.

Use 'config false;' for the configured parameters and 'config true;' for the operational statistics.

Part of the YANG domain, which makes up ~15% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–9 in this domain), expect 2–3 from this objective — we provide 20 practice questions to prepare you well beyond it.
