A developer is designing a REST API that will be used by multiple client applications. The API must support versioning to ensure backward compatibility. Which approach should the developer use to implement API versioning?
Embedding the version in the URI (e.g., /v1/resource) is the most common and straightforward approach for REST API versioning. It makes the version explicit in the URL, allowing clients to directly target a specific version without requiring special header handling or query param…Read full explanation
A development team is implementing a microservices architecture. They need to ensure that services can discover each other dynamically without hardcoding IP addresses. Which technology should they use?
A service registry like Consul provides a centralized directory where microservices register their network locations (IP and port) and health status. Other services query the registry to discover available instances dynamically, eliminating the need for hardcoded addresses. Consu…Read full explanation
A developer is writing a Python script that uses the Cisco Meraki API to retrieve a list of networks for an organization. The API returns a JSON array. The developer wants to filter networks where the 'tags' field contains 'production'. Which code snippet correctly filters the results?
Option A is correct because the Meraki API returns the 'tags' field as a list of strings (e.g., ['production', 'critical']). The Python `in` operator directly checks membership in a list, so `'production' in net['tags']` efficiently filters networks where the exact string 'produc…Read full explanation
