A platform accepts a high-level-looking API request. Which additional capability most strongly indicates that the platform is providing intent-based management rather than merely accepting configuration input?

A
The API request contains fewer fields than a device configuration
B
The system interprets the desired outcome and determines how to achieve and assure it
C
The API accepts a request without returning an error
D
The request uses standardized data models

True or false

Combining topology and inventory data
B
Replacing every operator approval with automatic authorization

What is the concise term for operational goals and outcomes expressed declaratively, without specifying the implementation steps?

Choose one

1 point

A controller connection is interrupted. What is the most accurate expectation about the network’s behavior?

A
All network traffic must stop because control is centralized
B
Every device automatically switches to an identical backup controller
C
The effect varies with the architecture and controlled function; some devices may continue forwarding
D
Only the controller’s northbound interface is affected

An operator is preparing a controller change that affects two sites. Which practices fit a disciplined controller-platform workflow? Select all that apply.

A
Inspect inventory, topology, configuration, and operational state before making changes
B
Use approved credentials and the least privilege needed
C
Treat an API success response as sufficient proof that the requested service works
D
Verify the requested behavior, not only whether the API returned success

Open ended

A controller has applied changes intended to keep two sites connected and their traffic isolated. Explain how it should determine whether the intent is being maintained and what it may do if observed network state diverges from the desired outcome.

Choose one

1 point

A controller API reports that a service request was accepted, but the operator needs to know whether the service is operational. What should the operator conclude and do next?

A
The controller may have accepted the request without completing it; check deployment status and resulting service state
B
The change is complete because acceptance guarantees successful deployment
C
The change cannot be verified until the API rejects the request
D
The operator should repeat the request immediately until the API reports a different status

An operator wants traffic between two networks to remain isolated but does not specify how devices should be configured. Which statement expresses this request as intent?

A
Assign specific VLANs and access-control entries to particular interfaces.
B
Keep traffic between two networks isolated without prescribing device commands.
C
Configure a fixed list of interface settings on every participating device.
D
Apply a specified sequence of commands to selected network devices.

A network team wants a unified point of administration but needs the controller software to run across several machines for capacity and resilience. Which statement best describes this design?

A
A controller is centralized only when all its software runs on one server.
B
A distributed controller cannot provide a unified view of the network.
C
A controller may be physically distributed while remaining logically centralized.
D
A logically centralized controller requires all forwarding decisions to be made by one machine.

A controller detects that the network no longer matches an operator's desired state. Which intent-lifecycle stage addresses this divergence by notifying an operator or taking permitted corrective action?

A
Reconcile
B
Ingest and validate
C
Translate and plan
D
Fulfill

A team is designing programmatic network management. Which statement correctly distinguishes YANG from NETCONF and RESTCONF?

A
YANG is a protocol, while NETCONF and RESTCONF are configuration models.
B
YANG and NETCONF are controller interfaces, while RESTCONF is an assurance function.
C
NETCONF and RESTCONF are data models, while YANG is a device-discovery protocol.
D
YANG models configuration and state, while NETCONF and RESTCONF provide ways to interact with YANG-modeled data.
