   A team is designing a configuration file for a network device that must be edited by both network engineers and parsed by an automation system. The engineers prefer a format that supports comments and is easy to read, while the automation system requires strict data typing and validation. The team is considering YAML and JSON. Which choice best balances these requirements?

   • AUse CSV for the master file and convert to both YAML and JSON
   • BUse XML for the master file and convert to both YAML and JSON
   • CUse YAML for the master file and convert to JSON for the automation system
   • DUse JSON for the master file and convert to YAML for the engineers

   A network engineer is troubleshooting a script that parses a device configuration exported by a legacy system. The script uses json.loads() and fails with a JSONDecodeError. The engineer inspects the file and sees lines like '<interface name="GigabitEthernet0/1"><status>up</status></interface>'. What is the most likely cause of the failure?

   • AThe file is YAML, not JSON, so json.loads() cannot parse it
   • BThe file is CSV, not JSON, so json.loads() cannot parse it
   • CThe file is XML, not JSON, so json.loads() cannot parse it
   • DThe file is valid JSON but contains a syntax error
