An administrator wants to get information about a specific host and runs this code: GET/v1/hosts/{sn} An API code 404 is returned What is the reason for the error code?

The HTTP status code 404 Not Found indicates that the server was unable to locate the specific resource requested by the client. In the context of the REST API call GET /v1/hosts/{sn}, the resource is a host identified by its serial number (sn). Therefore, a 404 response means that the serial number provided in the API request URI does not correspond to any existing host within the VxRail cluster, making it an invalid identifier for this operation.

A. A failure in authentication would typically result in a 401 Unauthorized status code, not a 404 Not Found.
C. A server-side processing error would be indicated by a 5xx series status code, such as 500 Internal Server Error.
D. The API endpoint GET /v1/hosts/{sn} is specifically designed to retrieve a single host. The endpoint to get all hosts would be GET /v1/hosts.

Table "Common response status codes".

The document explicitly defines the 404 Not Found code as: "The server has not found anything matching the request URI." This confirms that the issue is with the resource identifier in the URI.

Section "GET /v3/hosts/{sn}".

Under the "Responses" for this endpoint (which is functionally identical to the v1 endpoint in the question)

the 404 response code is described with the message: "A host with the specified serial number cannot be found." This directly supports the conclusion that an invalid {sn} is the cause.

The document defines 401 Unauthorized for authentication issues and 500 Internal Server Error for server-side failures

which rules out options A and C.
