Start Understanding and Using APIs PracticeWhat HTTP method should be used to update only the description field of a network device resource via a REST API?
Explanation: PATCH is used for partial updates, whereas PUT replaces the entire resource. GET retrieves, POST creates, DELETE removes.
A developer is building a script to retrieve a list of network devices from Cisco DNA Center. The API response includes a 'nextToken' field in the body to indicate more results. What pagination method is being used?
Explanation: Cursor-based pagination uses a token (e.g., nextToken) to point to the next set of results, unlike offset/limit which uses page numbers.
Which HTTP header is used to specify the format of the request body (e.g., application/json) when sending a POST request to a REST API?
Explanation: Content-Type indicates the media type of the request body. Accept indicates the desired response format. Authorization carries credentials.
A developer is using the Meraki Dashboard API and receives a 429 Too Many Requests error. The API documentation states a rate limit of 5 calls per second. What is the best practice to handle this?
Explanation: Implementing exponential backoff with retry-after headers is the recommended approach for rate-limited APIs. Ignoring or simply retrying immediately may worsen the situation.
Which OAuth 2.0 grant type is most appropriate for a server-to-server integration where no user interaction is required, such as a backend service calling Cisco API?
Explanation: Client credentials grant is designed for server-to-server scenarios without user consent. Authorization code requires user interaction. Device code is for devices with limited UI.
