To prepare for this certification test, you should review its content outline available on the official webpage. Thus, it consists of 4 main topics, which include the following:

• Orchestration & Automation Platforms (30%): Here, it is important to know how to identify the use cases of Cisco WAE and the benefits of NSO, construct a service template, and deploy a service package. You should also have the skills in implementing XR traffic controller and describing NSO architecture.
• Network Device Programmability (30%): This area covers the details of the deployment of device configuration and validation of the operational state with the use of ncclient, comparison of gNMI and NETCONF, as well as construction of a Python script with the use of NETCONF and YDK. It will also evaluate your knowledge of the Xpath notation, NetMiko, gRPC, and Ansible playbooks.
• Network Programmability Foundation (10%): This is the last domain covered in the Cisco 300-535 exam. It is all about the utilization of common version control operations with git, benefits of using network configuration tools, as well as Python scripts, which contain data functions, types, conditions, looping, and classes.
• Automation APIs & Protocols (30%): For this topic, a potential candidate has to possess the skills in comparing the common data types (plain text, JSON, gRPC, XML, etc.), implementing the operation and configuration management with the use of the RESTCONF protocol, and interpreting a YANG module tree, which is generated by pyang.
