Which two data structures are used in JSON? (Choose two.)

The JSON (JavaScript Object Notation) data interchange format is built upon two fundamental structures. The first is an object, which is an unordered collection of key/value pairs enclosed in curly braces ({}). The second is an array, which is an ordered list of values enclosed in square brackets ([]). These two structures, combined with primitive data types (strings, numbers, booleans, and null), constitute the entirety of the JSON syntax.

A. tuples: This is an immutable data structure specific to languages like Python and is not a native data structure defined in the JSON standard.

D. dictionaries: While a JSON object is functionally equivalent to a dictionary in many programming languages, the official term used in the JSON standard is "object".

1. Internet Engineering Task Force (IETF) RFC 8259: "The JavaScript Object Notation (JSON) Data Interchange Format", Section 1, Introduction. This document, which defines the JSON standard, states: "JSON is built on two structures: A collection of name/value pairs. In various languages, this is realized as an object... An ordered list of values. In most languages, this is realized as an array..."

2. Juniper Networks TechLibrary: "Junos OS Automation Scripting User Guide", section "JSON Data Format for Configuration Data". This official Juniper document specifies: "JSON data consists of two structures: A collection of name/value pairs, called an object. An ordered list of values, called an array."
