A developer is integrating a custom application with network devices using RESTCONF. The application needs to retrieve a list of all active interfaces from a device. Which HTTP method is typically used in RESTCONF for retrieving resources?
- ADELETE
- BGET
- CPOST
- DPUT
Show answer & explanationAnswer & explanation
Correct answer: B. GET
RESTCONF leverages standard HTTP methods for its operations. To retrieve or read resources (like a list of active interfaces), the HTTP GET method is used. POST is for creating, PUT for updating/replacing, and DELETE for removing resources.
Why the other options are wrong
- A. DELETE is used to remove resources.
- C. POST is used to create new resources.
- D. PUT is used to update or replace existing resources.
RESTCONF GET
In RESTCONF, the HTTP GET method is used to retrieve configuration data, operational state data, or specific resources from a network device.
- Uses standard HTTP GET method.
- Retrieves data from the device.
- Non-modifying operation.
- Part of RESTCONF's CRUD operations.
Memory trick: RESTCONF maps CRUD to HTTP verbs.
