What is a key advantage of YANG-based modeling over traditional CLI-based configuration?

YANG is faster than CLI for all configuration tasks

YANG eliminates the need for network device operating systems

YANG requires no authentication or authorization

YANG provides a structured, machine-readable data model that is consistent across devices

What is the primary role of YANG in network management?

To provide a transport protocol for sending configuration data to network devices

To define a data modeling language that describes configuration and state data for network devices

To replace the need for network device operating systems

To encrypt data transmitted between network management systems and devices

In a YANG model, which statement correctly describes the relationship between containers, lists, and leaf nodes?

Containers, lists, and leaf nodes are all at the same level in the hierarchy

Leaf nodes can contain containers and lists

Lists can contain containers, but containers cannot contain lists

Containers can hold lists and leaf nodes, and lists can hold leaf nodes

How does YANG-based management differ from SNMP in terms of data modeling?

YANG is a transport protocol, while SNMP is a data modeling language

YANG is only used for monitoring, while SNMP is used for configuration

YANG models are hierarchical and can represent configuration and state, while SNMP MIBs are flat and primarily for monitoring

YANG and SNMP use the same data model structure

A network engineer is writing a Python script to automate configuration of a switch using NETCONF. The YANG model defines a leaf called 'duplex' with type enumeration { half, full, auto }. The engineer wants to set the duplex mode to full. Which value should be sent in the NETCONF edit-config operation?
