A service provider is considering using YANG to automate the configuration of a large number of devices. The automation team is concerned about the performance of NETCONF when applying configuration to many devices. Which approach is most likely to improve performance while still using YANG?

Use RESTCONF with HTTP/2 to enable multiplexing and reduce latency.

Use NETCONF with the 'candidate' datastore to stage changes before committing.

Use CLI scripting instead of NETCONF to speed up configuration.

Use NETCONF with the 'running' datastore to apply changes immediately.

A network architect is designing a YANG module for a new service. The architect wants to reuse a common set of definitions, such as IP address and prefix types, across multiple modules. Which YANG feature should be used to achieve this reusability?

A submodule that is included by multiple modules

An rpc statement that defines common operations

A notification statement that defines common events

A leaf-list that contains all the common definitions

A service provider is replacing a set of vendor-specific CLI scripts that configure BGP and MPLS on edge routers. The new automation platform must be able to validate configuration changes before applying them and must work across routers from multiple vendors. Which approach best meets these requirements?

Use a Python script that parses the running configuration and sends CLI commands.

Use vendor-specific CLI templates with a configuration management tool.

Use SNMP MIBs to set configuration parameters on the routers.

Use YANG models with NETCONF/RESTCONF to describe and validate the configuration data.

A service provider wants to automate the provisioning of new customer VPNs across a multi-vendor network. The automation team is evaluating YANG as the data modeling approach. Which benefit of YANG is most directly relevant to this multi-vendor automation effort?

YANG automatically translates configuration to CLI commands on any device.

YANG provides a standardized, vendor-neutral way to describe configuration and state data.

YANG models are always backward-compatible with older device software.

YANG eliminates the need for any device-specific configuration.
