350-201 Question 264
Single answerWhile troubleshooting an issue with a Cisco security device that uses REST APIs, you observe that the API response includes HTTP status code 401. What does this status code indicate, and what is the most likely cause of the issue?
- A
The request was successful, and the resource was created.
- B
The client is not authorized to access the requested resource due to missing or invalid authentication.
- C
The server encountered an error and could not complete the request.
- D
The requested resource could not be found on the server.
Show answer and explanation
Correct answer: B
Explanation
HTTP status code 401 is commonly associated with REST API authentication errors. This response indicates that the client has not provided valid credentials or that the credentials are missing, and therefore the server denies access to the requested resource. In the context of Cisco security technologies, this could occur if the API client is not properly configured with the required authentication token or credentials.
- A. Incorrect.
This is incorrect. HTTP status code 201 indicates that a resource was successfully created, not related to authorization issues.
- B. Correct.
This is correct. HTTP status code 401 indicates an authentication failure, typically due to missing or invalid credentials.
- C. Incorrect.
This is incorrect. HTTP status code 500 indicates a server-side error, unrelated to authentication or authorization.
- D. Incorrect.
This is incorrect. HTTP status code 404 indicates that the resource was not found on the server, unrelated to authentication.
