400-007 · Question #242

Which feature is supported by NETCONF but is not supported by SNMP?

The correct answer is A. distinguishing between configuration data and operational data. NETCONF uniquely distinguishes between configuration datastores and operational state data, a separation that SNMP does not provide due to its flat MIB-based architecture.

Why each option

NETCONF uniquely distinguishes between configuration datastores and operational state data, a separation that SNMP does not provide due to its flat MIB-based architecture.

Adistinguishing between configuration data and operational dataCorrect

NETCONF explicitly models separate datastores - running, candidate, and startup - for configuration data and provides distinct operations such as get-config versus get to retrieve configuration versus live operational state. SNMP's MIB hierarchy conflates configuration and operational data within the same object tree, offering no formal mechanism to differentiate between the two types of data.

Btaking administrative actions

Both NETCONF and SNMP support administrative actions - NETCONF through RPC operations and SNMP through SET operations on writable MIB objects.

Ccollecting the status of specific fields

Both protocols support collecting status of specific fields - NETCONF via get with subtree or XPath filters and SNMP via GET requests for specific OIDs.

Dchanging the configuration of specific fields

Both protocols can change specific configuration fields - NETCONF via edit-config and SNMP via SET operations on writable MIB objects.
