Correct Answer: A
Answer A is the technically correct selection. HTTP status code 200 indicates a successful REST API request.
The exact successful code can vary by operation, but 200 OK is the standard success response in this answer set. This aligns with Cisco CCNA 200-301 v1.1 because the exam blueprint requires engineers to recognize operational behaviour from configuration symptoms and topology requirements. 301 is redirection, 404 is not found, and 500 is a server-side error. Treat the distractors carefully: most are real Cisco terms, but they solve a different problem or operate at a different layer. The selected answer is the one that would be used by an engineer on the device or in the design to produce the outcome stated in the question.
