A network operations team is planning to automate configuration management for a fleet of legacy devices that only support SNMP and CLI, and newer devices that support NETCONF/YANG. The team wants a single automation framework that can manage both types of devices. Which strategy is most effective?

Force the legacy devices to support NETCONF by upgrading their firmware.

Use NETCONF/YANG for the newer devices and a separate CLI/SNMP abstraction layer for the legacy devices, with a common data model in the automation framework.

Use only SNMP for all devices, since it is universally supported.

Use only CLI scripting for all devices, since it works everywhere.

A network engineer is automating the initial configuration of a new router using NETCONF. The YANG model defines a container 'system' with a leaf 'hostname' of type string and a leaf 'domain-name' of type string. The engineer wants to set both values in a single edit-config operation. The device currently has no configuration for these leaves. Which NETCONF operation and payload should be used?

Use the 'delete' operation with both leaves in the payload.

Use the 'merge' operation with both leaves in the payload.

Use the 'replace' operation with both leaves in the payload.

Use the 'create' operation with both leaves in the payload.

A network administrator is using RESTCONF to update the description of an interface. The YANG model defines a leaf 'description' of type string under the list 'interface'. The administrator wants to change the description from 'old' to 'new'. Which HTTP method and payload should be used?

GET with the new description value in the request body

DELETE with the new description value in the request body

PUT with the new description value in the request body

POST with the new description value in the request body

A YANG model defines a leaf 'admin-status' with type 'enumeration' and values 'up', 'down', and 'testing'. An automation script needs to set this leaf to 'testing' on a device. Which value should the script send in a NETCONF edit-config operation?
