Difficulty: EasyCharacteristics of REST-Based APIs (CRUD, HTTP Verbs, Data Formats)

Match each HTTP verb commonly used in REST-based network automation APIs to its corresponding CRUD operation.

  • GETRead
  • POSTCreate
  • PUTUpdate / Replace
  • DELETEDelete

Answer

GET maps to Read, POST maps to Create, PUT maps to Update / Replace, and DELETE maps to Delete.
In REST-based APIs, standard HTTP verbs correspond directly to CRUD operations: GET retrieves information (Read), POST creates new resources (Create), PUT updates or overwrites existing resources (Update), and DELETE removes resources (Delete).

Step-by-Step Solution

1
Identify the primary function of each HTTP request method in RESTful web services.
GET retrieves data; POST creates data; PUT updates/replaces data; DELETE removes data.
REST architecture standardizes data operations by mapping HTTP methods directly to database operations.
2
Match each HTTP verb to its corresponding acronym component in CRUD (Create, Read, Update, Delete).
POST = Create, GET = Read, PUT = Update, DELETE = Delete.
This 1-to-1 mapping is a fundamental characteristic of REST-based API design.
