                                  NEW QUESTION # 156
                                  iMaster NCE-Campus restricts RESTful APIs. If a client sends a GET request that invokes a RESTful API to obtain site information from iMaster NCE-Campus, which of the following fields should be included in the request header?

                                  Answer: C

                                  Explanation:
                                  Comprehensive and Detailed In-Depth
                                  When invoking RESTful APIs in iMaster NCE-Campus, the client must include the ACCESS-TOKEN in the request header to authenticate the request.
                                  The ACCESS-TOKEN is obtained through authentication and is required for API access control.
                                  The correct format in the HTTP header is:
                                  Authorization: Bearer ACCESS-TOKEN
                                  Other formats like ACCEPT-TOKEN, X-ACCEPT-TOKEN, and X ACCESS TOKEN are not recognized or valid for iMaster NCE-Campus API requests.
                                  Therefore, the correct answer is A.
