An orchestration system needs to send a service request to a network controller. Which interface direction connects these two parts of the architecture?

A
An interface between a controller and network devices
B
An interface between an orchestration system or application and a controller
C
An interface used only for reading device counters
D
An interface between two network devices for forwarding traffic

In a common network-management architecture, interfaces connecting a controller to devices or lower-level network systems are called interfaces.

Which interface provides HTTP-based access to YANG-modeled network data and operations?

A
NETCONF: RPC-based operations for retrieving and modifying device configuration.
B
RESTCONF: HTTP-based access to YANG-modeled data and operations.
C
YANG: a language that defines the structure and constraints of management data.
D
A controller: a guarantee that vendors implement every modeled feature identically.

A team is preparing a network change and wants to reduce the risk of a broad failure. Select all practices supported by the recommended controlled workflow.

A
Validate syntax, model constraints, policy, dependencies, and authorization before deployment.
B
Review proposed changes and estimate their impact before applying them.
C
Deploy to a test or canary group before wider rollout when appropriate.
D
Apply the change to every device first, then check whether it was valid.
E
Treat controller acceptance as sufficient proof that the service behaves as intended.

What term names a limited group of devices or systems used to try a change before a wider rollout?

Choose all

1 point

Which statements accurately describe infrastructure as code practices? Select all that apply.

A
Desired infrastructure definitions can be stored in files that are versioned, reviewed, tested, and applied through a controlled workflow.
B
IaC files should replace operational verification because declared state guarantees service behavior.
C
Environment-specific values should be separated from reusable logic where practical.
D
IaC applies only to cloud and compute resources, not network resources.

An operator requests a quality-of-service policy for an application across several sites. Which controller role best explains how that request can be implemented across devices?

A
It can translate higher-level requests into lower-level device configuration while coordinating policy or intent.
B
It guarantees every device implements every feature in a shared model identically.
C
It replaces the need to check device-level results after a change.
D
It only forwards packets and does not gather topology or device information.

Explain how applications or services, a controller or management system, and network devices contribute to implementing a network request. Why should the workflow verify device-level results even when the controller accepts the request?

Which statement best describes what a YANG model provides and what it does not guarantee?

A
A YANG model guarantees that every vendor implements every modeled feature identically.
B
A YANG model defines management data structure, meaning, types, and constraints, but vendor support and implementation can vary.
C
A YANG model is a device command-line syntax that replaces APIs.
D
A YANG model proves that a configured service is operational.

An orchestration application needs to send a service request to a network controller. Which interface direction is intended for this connection?

A
They connect devices to lower-level network systems.
B
They connect applications or orchestration systems to a controller or management platform.
C
They connect a controller to users' endpoint applications.
D
They connect network devices directly to one another.

A client must access YANG-modeled data and operations over HTTP. Which protocol best fits this requirement?

A
NETCONF provides HTTP-based access, while RESTCONF uses RPC-based operations.
B
Both protocols require a conventional agent on each managed device.
C
RESTCONF provides HTTP-based access to YANG-modeled data and operations.
D
RESTCONF is a data modeling language used to define configuration fields.

An interface is configured with an address, but a service test fails. Which distinction should guide the investigation?

A
Configuration describes intended settings, while operational state reports actual runtime behavior.
B
Configuration reports runtime counters, while operational state stores intended policy.
C
Configuration and operational state are interchangeable names for the same data.
D
Operational state is only available before configuration is applied.

A client needs to distinguish a valid interface address from an arbitrary string. What role does a YANG model play?

A
It guarantees that every vendor implements every modeled feature identically.
B
It defines data structure and constraints so clients can interpret management data consistently.
C
It replaces the need to check which features a device supports.
D
It automatically confirms that a configured service is working.
