Which of the following is a management operation in NETCONF?

In the context of NETCONF, which is a network management protocol designed to manage network devices in a standardized way, the "Get" operation is fundamental. This operation allows the client to retrieve the configuration and state data from the managed devices. It is part of the core set of operations defined in the NETCONF protocol, which are essential for accessing, modifying, and managing network configurations.

The "Get" operation specifically allows users to request specific data from the device, making it a critical aspect of how network administrators gather information necessary for effective management and monitoring. This can include retrieving interfaces' status, configuration settings, and operational statistics from devices in a consistent manner.

In contrast, the other choices relate to different aspects of network management or communication protocols. SNMP (Simple Network Management Protocol) is a different protocol used for network management, MIB (Management Information Base) serves as a database for SNMP containing information about the managed devices, and BER (Basic Encoding Rules) is a type of encoding used in data serialization. While these are all relevant to network management, they do not represent the specific management operations defined within the NETCONF framework.
