A DevOps team manages a multi-site Cisco Meraki network with 50 MX appliances and 200 MR access points. They use a Python script that calls the Meraki API to collect device utilization data every hour and stores it in a CSV file. Recently, the script started failing intermittently with HTTP 429 status codes. The team suspects rate limiting but notices that the failures occur even when only one script instance runs. The script uses a single API key and makes requests to the /devices/{serial}/uplink endpoint for each MX and the /devices/{serial}/wireless/status endpoint for each MR. The script is scheduled via cron and runs sequentially. The team wants to resolve the rate limiting while minimizing changes to the script. Which course of action should the team take?

The request fails with HTTP 400 status and the response body: '{"error": "Bad Request", "details": "Invalid JSON: unexpected token at position 42"}'. Which tool or technique should the developer use to quickly identify the syntax error?

A DevOps engineer is designing a REST API for a custom network automation tool. Which principle is essential for a RESTful design?

A large enterprise uses Cisco Meraki for their wireless and switching infrastructure. The network team has developed a Python script that uses the Meraki API to automatically update SSID configurations across all networks. The script has been running successfully for months, performing daily updates to SSID settings such as names, passwords, and VLAN assignments. Recently, the script started failing with the following error message: '{"errors":["This operation is not allowed for this network"]}'. The team has verified the following: the API key is still valid and has access to the full organization, the network IDs used in the script are correct and the networks are active, and no changes have been made to the script code. The script uses the PUT endpoint '/networks/{networkId}/wireless/ssids/{number}' to update SSIDs. What is the most likely cause of the failure?

You are a junior network developer tasked with automating device inventory retrieval using the Cisco Meraki Dashboard API. You have already generated an API key with the appropriate scopes and have tested it successfully with simple GET requests. However, when you attempt to retrieve the list of all devices in your organization via the 'GET /organizations/{organizationId}/devices' endpoint, you receive a 403 Forbidden error. You verify that the API key is correctly included in the request header as 'X-Cisco-Meraki-API-Key'. You also confirm that the organization ID is correct. You are able to reach the Meraki Dashboard API server from your environment, as other endpoints (e.g., 'GET /organizations') work fine. What is the most likely cause of the 403 error, and what should you do to resolve it?

You are a network automation engineer using the Cisco DNA Center REST API to retrieve health scores for all sites in your network. You call the 'GET /dna/intent/api/v1/site-health' endpoint with parameters to filter by time range. The response returns only the first 20 sites out of a total of 150 sites. You notice that the response includes a 'totalRecords' field showing 150, but only 20 objects are in the 'response' array. You recall that the API documentation mentions pagination support. To avoid manually looping through all pages, you want to implement a robust solution that efficiently retrieves all site health data. Which approach should you take?
