Answers

D.

Add the -H ‘Content-Type: application/yang-data+json’ header.

Answers
D.

Add the -H ‘Content-Type: application/yang-data+json’ header.

Suggested answer: D

Explanation:

The HTTP 401 Unauthorized error indicates that the request lacks proper authenticationcredentials. However, in this case, the credentials are provided, so the issue likely stems from a

missing or incorrect header. The Content-Type header is necessary for many REST APIs tospecify the format of the request body. Adding the Content-Type: application/yang-data+jsonheader ensures that the server correctly interprets the request as JSON formatted dataaccording to the YANG data model.
