350-401 Question #1269: Real Exam Question with Answer & Explanation

Question

Refer to the exhibit. Which HTTP request produced the REST API response that was returned by Cisco DNA Center?

Options

• APUT /network-device?macAddress=ac:4a:56:6c:7c:00
• BGET /network-device?macAddress=ac:4a:56:6c:7c:00
• Cfetch /network-device?macAddress=ac:4a:56:6c:7c:00
• DPOST /network-device?macAddress=ac:4a:56:6c:7c:00

Explanation

The provided JSON response shows data being retrieved about a network device, indicating that a GET request was used to query the Cisco DNA Center API.

Common mistakes.

• A. PUT requests are typically used to update an existing resource or create one if it doesn't exist, which would usually return a status indicating the modification, not a list of device properties.
• C. "fetch" is not a standard HTTP method in RESTful APIs; GET is the standard method for retrieving resources.
• D. POST requests are used to create new resources on the server, and the response would typically be an identifier for the newly created resource or a confirmation of creation, not details of an existing device.

Concept tested. REST API HTTP methods (GET)
