I am a network engineer, not a developer. The prospect of coding/scripting questions on the ENCOR 350-401 exam is terrifying. How deep do they go into Python or API calls? Do I need to be able to write code from scratch, or is it more about reading and interpreting snippets?
The ENCOR 350-401 exam focuses on reading and interpreting code snippets, API data structures, and automation logic rather than requiring candidates to write functional code from scratch.

You are not expected to act as a software developer, but you must be able to parse logic flow and identify correct syntax within the context of network automation. Focus your preparation on interpreting JSON, XML, and YAML data models, as well as understanding the fundamental structure of RESTful API calls. You will be tested on identifying logical errors in provided script snippets rather than creating architecture from a blank editor.
When I sat for my early architecture certifications, the inclusion of scripting felt like a departure from traditional CLI-based validation, but I remember realizing that the syntax was just another language for describing state changes. I spent my prep time printing out simple Python loops and marking them up with highlighters to map the variable assignments to the actual infrastructure components I managed daily.
It is worth noting that once I began visualizing the API calls as serialized data packets replacing manual configuration commands, the fear subsided significantly. You eventually stop seeing lines of code as an abstract programming task and start seeing them as a more efficient way to perform the same repetitive tasks you have handled in UCS Manager or the shell for years.
Stop worrying about building entire applications because the exam is strictly scoped to reading and logic verification.
- Focus on identifying syntax errors in Python snippets
- Master the interpretation of REST API status codes
- Learn to distinguish between data serialization formats like JSON and XML
- Understand the role of NETCONF and RESTCONF in modern network state management
