Function Availability Comparison: NETCONF vs RESTCONF

D.

NETCONF (Network Configuration Protocol) and RESTCONF (RESTful Network Configuration Protocol) are both protocols used for managing network devices. While they share some similarities, such as their use of YANG data models and XML encoding, there are some differences between them.

The function that is available in NETCONF and unavailable in RESTCONF is D. validates the content of a candidate datastore.

In NETCONF, a candidate configuration datastore is used to temporarily store changes before they are committed to the running configuration datastore. The validation process in NETCONF checks the content of the candidate datastore against the constraints defined in the YANG data models to ensure that the changes are valid before they are committed to the running configuration. This helps to avoid configuration errors and ensures that the network is configured correctly.

In RESTCONF, there is no concept of a candidate datastore. Instead, configuration changes are made directly to the running configuration datastore. While RESTCONF does support data validation using YANG data models, it does not have the same level of validation as NETCONF because there is no separate candidate datastore to validate.

To summarize, the function that is available in NETCONF and unavailable in RESTCONF is the ability to validate the content of a candidate datastore. NETCONF uses a candidate datastore to store changes temporarily and validates the content of this datastore before committing changes to the running configuration. RESTCONF does not have a candidate datastore and does not perform the same level of validation as NETCONF.
