A lightweight, human-readable data format used to exchange data between APIs and automation tools.
Full Definition
JSON is the most common data format used in network automation and REST APIs. It represents data as key-value pairs, arrays, and nested objects. Cisco devices and controllers use JSON in API responses and configuration payloads. Understanding JSON structure is required for reading API responses and writing automation scripts using Python or Ansible.
Real-World Example
{ "interface": "GigabitEthernet1", "ip": "192.168.1.1", "mask": "255.255.255.0", "enabled": true }
Exam Trap — Don't Get Fooled
JSON uses double quotes for keys and string values (not single quotes). Boolean values are true/false (lowercase), not True/False. The CCNA exam may present a JSON snippet and ask you to identify a specific value.
