What NETCONF management operation is used to retrieve parts of the specified configuration data store?

The operation used to retrieve parts of the specified configuration data store in NETCONF is <get-config>. This operation specifically allows a client to access configuration data stored in the device’s data model, whereas other operations do not have this specific focus.

When a NETCONF client sends a <get-config> request, it specifies the target data store it wants to retrieve information from. This can include either the running configuration, the startup configuration, or other types of configurations defined within the device's data model. This operation is crucial for network management as it enables the retrieval and examination of the current configuration settings and values stored on network devices.

In contrast, the <get> operation retrieves operational state data, which includes current values and status of devices but does not focus specifically on configuration data. The other choices, such as <fetch-config> and <read-config>, are not standard NETCONF operations, hence they wouldn't successfully accomplish the task of retrieving configuration data in accordance with the NETCONF protocol standards.
