A developer is designing an API endpoint for updating user profiles where partial update is expected. Which HTTP method should be used?
- PATCH
- POST
- PUT
- UPDATE
When a partial update is expected in an API endpoint, the appropriate HTTP method to use is PATCH. PATCH is designed to apply partial modifications to a resource, making it suitable for updating specific fields in a user profile without affecting the entire resource.
What feature of API Gateways helps in managing the load on backend services?
- Load balancing
- Load lifting
- Load shedding
- Load stacking
API Gateways use load balancing to distribute client requests evenly across backend services, preventing overloading of any single service.
