Question 700
A change advisory for Oakbridge University has two requirements: (1) provide a service-facing way for an application to request network policy from a controller, and (2) deliver controller policy to routers and switches using device-facing interfaces. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) Northbound APIs expose controller abstractions to higher-level orchestration or applications. (2) Southbound interfaces connect the network controller to forwarding infrastructure. Neither action is a substitute for the other.
Incorrect Answers
The second step covers (2), but the first addresses create a new resource through a REST API with a request body. POST commonly submits resource creation or actions with a payload. It leaves outcome (1) unfulfilled.
The first step covers (1), but the second addresses represent an ordered collection of network interfaces in JSON. JSON arrays contain ordered elements which can be objects, scalars or other arrays. It leaves outcome (2) unfulfilled.
Neither step is the requested pair: Use inventory to define hosts and playbook to define ordered tasks is for distinguish an Ansible inventory from an Ansible playbook, and Separate property pairs with commas and quote property names is for avoid a syntax error when a JSON object has several fields. Inventory specifies managed endpoints while a playbook expresses operations to perform. The proposed plan misses the two stated outcomes.
