Slide 44 shows A would be correct for NETCONF. C would be the correct answer as we are using RESTCONF.

Selected Answer: A

should be A, as in learning LABs from CISCO https://developer.cisco.com/learning/labs/intro-restconf/ RESTCONF Headers and MIME Types One of the major advantages RESTCONF has over NETCONF is its ability to use JSON as a data format. Many developers prefer JSON (over XML) because of its readability and lower overhead. When crafting a RESTCONF request, you specify the data format being sent and requested by the agent. This is done in a typical HTTP way; using request headers: Content-Type: Specify the type of data being sent from the client Accept: Specify the type of data being requested by the client RESTCONF describes the following MIME types to be used in these headers to indicate the format being requested. application/yang-data+json application/yang-data+xml

Selected Answer: A

The correct MIME type for data transmitted using the RESTCONF protocol is application/yang.data+json, which indicates that the data is in JSON format and follows the YANG data model. Alternatively, if the data is transmitted in XML format, the MIME type would be application/yang.data+xml. Therefore, the correct line of code to place in the snippet where it is missing would be either {'Content-Type': 'application/yang.data+json', 'Accept': 'application/yang.data+json'} or {'Content-Type': 'application/yang.data+xml', 'Accept': 'application/yang.data+xml'}, depending on the format of the data being transmitted.
