Which configuration tool is used in conjunction with YANG for network management?

1. NETCONF

2. RESTCONF

3. CLI

4. SNMP

The correct answer is: NETCONF

NETCONF is the correct choice for the configuration tool used in conjunction with YANG for network management. It is a network management protocol that allows for the retrieval and modification of configuration and operational data from network devices. NETCONF interacts directly with YANG models, which define the data structures for configuration and state information in a network device. By utilizing YANG, NETCONF can convey complex data structures effectively and provide mechanisms for ensuring the integrity of configurations through transactions. This compatibility allows network engineers to manage devices more efficiently and ensures consistency in the network configuration. While RESTCONF is also a relevant protocol that leverages YANG models, its design is focused on using HTTP and REST APIs, making it more appropriate for web-based applications. The CLI, or Command Line Interface, is used for manual configuration but does not support the structured approach that YANG provides. SNMP (Simple Network Management Protocol) is primarily used for monitoring and managing network devices but does not directly utilize YANG for structured configuration management. Therefore, NETCONF is specifically tailored for working with YANG, making it the right tool for this purpose.
