Exam 200-901 topic 1 question 302 discussion

RESTCONF is a protocol for remotely accessing and modifying data defined in a data model. It is used to transfer data in JSON or XML format over HTTP. RESTCONF can be used to output device configuration in JSON format on a Cisco CSR 1000V instance. YANG is a data modeling language used to define data for network management. NETCONF is a network management protocol used to install, manipulate, and delete configuration data on network devices. SNMP (Simple Network Management Protocol) is a protocol used to monitor and manage network devices.

NETCONF supports only XML RESCONF supports both

The protocol used to output the device configuration in JSON format from a Cisco CSR 1000V instance that is deployed to a virtual machine is NETCONF (Network Configuration Protocol). NETCONF is a network management protocol that uses a simple Remote Procedure Call (RPC) mechanism to install, manipulate, and delete the configuration of network devices. It uses a data encoding format called XML (eXtensible Markup Language) or JSON, and it allows for the retrieval and manipulation of the configuration of a device in a programmatic way. The NETCONF protocol can be accessed via a secure transport such as SSH or TLS, and it can be used in conjunction with YANG data models to define the structure and content of configuration data. Cisco CSR 1000V supports NETCONF as well as other management protocols like REST API and SNMP.
