Are you ready to prepare for the DEVCOR Cisco Certified DevNet Professional certification exam ?

Developing Applications using Cisco Core Platforms and APIs (DEVCOR 350- 901) is a 120-minute exam associated with the DevNet Professional Certification. This exam tests a candidate’s knowledge of software development and design including using APIs, Cisco platforms, application deployment and security, and infrastructure and automation.

1.0 Software Development and Design

• Describe distributed applications related to the concepts of front-end, back-end, and load balancing
• Evaluate an application design considering scalability and modularity
• Evaluate an application design considering high-availability and resiliency (including onpremises, hybrid, and cloud)
• Evaluate an application design considering latency and rate limiting
• Evaluate an application design and implementation considering maintainability
• Evaluate an application design and implementation considering observability
• Diagnose problems with an application given logs related to an event
• Evaluate choice of database types with respect to application requirements (such as relational, document, graph, columnar, and Time Series)
• Explain architectural patterns (monolithic, services oriented, microservices, and event driven)
• Utilize advanced version control operations with Git
• Explain the concepts of release packaging and dependency management
• Construct a sequence diagram that includes API calls

2.0 Using APIs

• Implement robust REST API error handling for time outs and rate limits
• Implement control flow of consumer code for unrecoverable REST API errors
• Identify ways to optimize API usage through HTTP cache controls
• Construct an application that consumes a REST API that supports pagination
• Describe the steps in the OAuth2 three-legged authorization code grant flow

3.0 Cisco Platforms

• Construct API requests to implement chatops with Webex Teams API
• Construct API requests to create and delete objects using Firepower device management (FDM)
• Construct API requests using the Meraki platform to accomplish these tasks
• Construct API calls to retrieve data from Intersight
• Construct a Python script using the UCS APIs to provision a new UCS server given a template
• Construct a Python script using the Cisco DNA center APIs to retrieve and display wireless health information
• Describe the capabilities of AppDynamics when instrumenting an application
• Describe steps to build a custom dashboard to present data collected from Cisco APIs

4.0 Application Deployment and Security

• Diagnose a CI/CD pipeline failure (such as missing dependency, incompatible versions of components, and failed tests)
• Integrate an application into a prebuilt CD environment leveraging Docker and Kubernetes
• Describe the benefits of continuous testing and static code analysis in a CI pipeline
• Utilize Docker to containerize an application
• Describe the tenets of the “12-factor app”
• Describe an effective logging strategy for an application
• Explain data privacy concerns related to storage and transmission of data
• Identify the secret storage approach relevant to a given scenario
• Configure application specific SSL certificates
• Implement mitigation strategies for OWASP threats (such as XSS, CSRF, and SQL injection)
• Describe how end-to-end encryption principles apply to APIs

5.0 Infrastructure and Automation

• Explain considerations of model-driven telemetry (including data consumption and data storage)
• Utilize RESTCONF to configure a network device including interfaces, static routes, and VLANs (IOS XE only)
• Construct a workflow to configure network parameters with:
• Identify a configuration management solution to achieve technical and business requirements
• Describe how to host an application on a network device (including Catalyst 9000 and Cisco IOx-enabled devices)
