Q1Domain Verified
In the context of RESTful API design, which of the following best describes the principle of "Uniform Interface" and its implications for discoverability and loose coupling?
The exclusive reliance on proprietary protocols like SOAP for all communication, guaranteeing a highly controlled and secure environment.
The use of a single, monolithic endpoint to handle all client requests, simplifying development by reducing the number of URIs.
The requirement for clients to possess prior knowledge of all available resources and their specific URIs, ensuring predictable data retrieval.
The adoption of a standardized set of constraints that govern interactions between clients and servers, such as resource identification, manipulation through representations, and self-descriptive messages, promoting interoperability and independent evolution.
Q2Domain Verified
When designing a RESTful API for a system managing user profiles, which HTTP method would be most appropriate for partially updating an existing user's email address?
PUT
PATCH
POST
DELETE
Q3Domain Verified
Consider an API that exposes a collection of "orders." If a client wants to retrieve a specific order with ID "12345" and also include related "line items" in the same request, which of the following URI structures and query parameter best exemplifies a RESTful approach to achieve this?
`/api/v1/orders/get?id=12345&expand=line_items`
`/orders.fetch(id=12345, with=line_items)`
`/orders?id=12345&include=line_items`
`/orders/12345/line_items` (assuming line items are sub-resources)
