Breaking Down the Key Knowledge Areas of 350-901
Cisco 350-901 DEVCOR is a 120-minute exam that can be taken at Pearson VUE testing centers or online. Here's what you should know to pass it hassle-free:
- Cisco platforms
This section will assess your ability to construct API requests for implementing chatops with Webex Teams API, API requests for creating and deleting objects with the Firepower Device Management (FDM), and API requests for retrieving data from Intersight. Also, the questions under this section confirm if you understand AppDynamics and its capabilities, the construction of a Python script with the Cisco DNA center APIs for retrieving and displaying wireless health information, and Cisco DNA center APIs.
- Security and application deployment
The topics included in this domain cover the principles of end-to-end encryption, defining the secret storage approach, the use of Docker for containerizing an app, and diagnosing a CI/CD pipeline failure. Finally, the candidates have to understand the benefits of static code analysis as well as continuous testing, know effective strategies for logging, and more.
- Software development and design
This domain includes the concepts such as application design concerning scalability, modularity, resiliency, observability, and high availability. Also, the candidates will be expected to explain release packaging and dependency management principles, architectural patterns, and distributed applications. Finally, learners should know how to use advanced version control operations with Git and understand the construction of a sequence diagram that accommodates API calls.
- Using APIs
This topic requires mastery of the implementation of robust REST API error handling, skills in applying the control flow of consumer code as far as unrecoverable REST API errors are involved, and the ability to define possible approaches for optimizing API usage using cache controls. What's more, this domain will also confirm if you understand the OAuth2 concepts.
- Automation and infrastructure
This section is focused on the areas such as model-driven telemetry, setting up network parameters by constructing certain workflows, and the use of RESTCONF. Also, one should understand how to host an app on a network device and how to select the most appropriate configuration management solution.
