The Cisco Certified DevNet Professional certification is a must-have for anyone who wants to move a career forward. This certificate focuses on the candidates’ knowledge related to Cisco platforms, APIs, security, and more. To obtain this professional-level certification, the individuals need to pass two exams: one core test that covers software development and design for Cisco platforms and one of the concentration exams (there 8 options in total) that can help the specialists customize their certificate to their area of focus.

Prerequisites

The main target audience for this certification is the network engineers who want to expand their expertise, the developers who are seeking to learn more about DevOps and automation, as well as the solution architects who are trying to move to the Cisco ecosystem.

There are no formal requirements for earning the Cisco DevNet Professional certification. The only prerequisite is that the candidates should have at least a few years of experience developing as well as maintaining applications. It is recommended that they possess at least three years of experience in implementing and designing applications.

Exam Details

Any person who wants to obtain the Cisco DevNet Professional certification needs to start preparing for the 350-901 DEVCOR exam. The test is also known as Developing Applications using Cisco Core Platforms and APIs. It is 120 minutes long and consists of multiple-choice questions, but their number is unknown. This exam is available in the English language only and costs $400.

Completing the Cisco 350-901 test makes you a step closer to getting the Cisco DevNet Professional certification. The certificate is valid for 3 years, so after this time, you will have to recertify. You can do it by passing an upgraded version of the core exam or by completing the educational activities authorized by Cisco.

Exam Topics

There are five topics that the candidates need to cover in the Cisco 350-901 exam and each of them makes up 20% of the entire content. The first domain is ‘Software Development and Design’ that comes with the whole array of subtopics. Some of them are: constructing a sequence diagram that includes API calls; utilizing advanced version control activities with Git; explaining architectural patterns; evaluating the choice of database kinds taking into account application requirements; evaluating an application design taking into consideration modularity and scalability. The next subject area is ‘Using APIs’ that deals with implementing various APIs; describing the steps in the OAuth2 three-legged authorization code grant flow; constructing an application consuming REST API that supports pagination; identifying the ways to optimize API utilization via HTTP cache controls; implementing the consumer code control flow for unrecoverable REST API errors; and implementing robust REST API error handling for rate limits as well as time outs.

‘Cisco Platforms’ is the next topic that mainly focuses on the following areas: describing steps to build a custom dashboard to present data collected from Cisco APIs; describing the capabilities of AppDynamics when instrumenting an application; constructing a Python script with the help of Cisco DNA center APIs to retrieve and displaying wireless health information; constructing a Python script using UCS APIs; constructing API calls to retrieve data from intersight; constructing API requests using the Meraki platform; constructing API requests to create and delete objects with the help of Firepower device management; constructing API requests to implement chatops with Webex Teams API.

The ‘Application Deployment & Security’ domain is pretty straightforward. The skills that the applicants must possess to tackle the questions from this section include diagnosing a CI/CD pipeline failure; integrating an application into a prebuild CD environment; describing 12 factor app tenets; describing how end-to-end encryption applies to APIs; and more. The last area is known as ‘Infrastructure & Automation’. Here the students will have to focus on describing how to host an application on a network device; defining a configuration management solution; constructing a workflow to customize network parameters; utilizing RESTCONF to configure a network device; explaining considerations of model-driven telemetry.
