About Cisco 200-901 Exam
Earning the Cisco Certified DevNet Associate certification demonstrates your expertise in producing & maintaining applications that are created with the help of the Cisco programs. To obtain this certificate, you have to pass one exam known as 200-901 DEVASC: DevNet Associate. This test evaluates the candidates’ knowledge of the main principles of software design & development, including understanding and utilizing APIs, application development & security, Cisco platforms & development, as well as infrastructure & automation.
The formal prerequisites for this certification and its test are not presented, but it is crucial for the applicants to possess knowledge of exam objectives. Cisco 200-901 is designed for any individuals who wants to become a Software Developer in the future, or for those students who have a few years of expertise in developing software, including programming with Python.
The Cisco 200-901 exam has the allocated duration of 120 minutes. This test is available in English and Japanese, so you can choose the proper variant during the registration process. To register for this certification exam you have to pay the fee of $300 and create an account at the Pearson VUE website. Your next step is to go through the ‘Proctored Exams’ section and enter the codename of the test. To complete registration, you must follow the prescribed instructions.
There are various study materials that you can use to prepare for the Cisco 200-901 test. However, the official training course, Developing Applications & Automating Workflows Using Cisco Core Platforms (DEVASC) v1.0, will be enough for most learners. You will determine how to perform the basic network requests with the use of Cisco platforms as a base as well as how to perform automation processes across the network, computing, security & collaboration infrastructure. The course provides you with hands-on practice solving real-world difficulties with Cisco APIs & modern development devices. The duration of this training depends on the option you choose. Instructor-led training and virtual instructor-led training give you 5 days of classroom education in addition to 3 days of self-study, while e-Learning offers 8 days of self-paced instruction.
After you complete this training course, you should try to apply your knowledge in the exam. To do this, you can take several practice tests available online. Using this learning tool, you will be able to immerse yourself in the atmosphere of the exam and identify gaps in your knowledge.
The topics that are presented in the 200-901 DEVASC exam are as follows:
- Software Design & Development (15%)
The first domain of the Cisco 200-901 exam evaluates the candidates’ skills in comparing data formats and software development methods. They need to know about the analysis of standard data form into Python data structures as well as the notions of test-driven creation. It is recommended to be prepared to describe the advantages of version control and the benefits of creating code into classes, modules & methods/functions. Moreover, the students should have expertise in identifying the services of standard design models and utilizing standard version control processes with the help of Git.
- Understanding and Use of APIs (20%)
This subject area requires the learners’ understanding of common HTTP response codes connected with REST APIs, elements of an HTTP response, as well as common usage patterns related to webhooks. They should possess competence in constructing the REST API demand to perform a task dealt API documentation, as well as constructing a Python script, which names a REST API utilizing applications library, and solving a problem presented the HTTP responding language, documentation & request. Additionally, the individuals have to demonstrate their ability to identify constraints utilizing APIs, compare basic API styles, and use API authentication mechanisms, such as custom token, basic & API keys.
- Cisco Platforms and Development (15%)
The questions under this topic validate the professionals’ expertise in constructing a Python script, which is used by Cisco SDK provided SDK documentation, applying the concepts of model-driven programmability in a Cisco environment, and constructing code to execute a specific operation on the basis of given requirements and API reference documentation. They have to possess the expertise in the capacities of Cisco system management programs & APIs, Cisco count management programs & APIs, Cisco cooperation programs & APIs, and Cisco protection programs & APIs. The applicants also need to be able to tell the device-level APIs & dynamic interfaces for NX-OS & IOS XE as well as identify the relevant DevNet source for a supplied scenario.
- Application Deployment & Security (15%)
As for this part of the certification exam, it is about identifying the characteristics of several application deployment types & models as well as the application security issues related to secret protection, data handling & encryption, and the principles of DevOps practices. The test takers need to know about the advantages of edge computing, the details for a CD/CI pipeline in request deployments as well as top OWASP threats. They also must demonstrate their understanding of using Docker forms in a local development environment as well as Bash commands. In addition, the examinees need to be ready to create a Python total test, interpret contents of Dockerfile and explain DNS, reverse proxy, firewall & load balancers in application deployment.
- Infrastructure & Automation (20%)
Here the students should prove their competence in interpreting the results of a RESTCONF or NETCONF query, basic YANG models, unified diff, and a sequence diagram that includes API calls. They need to possess the knowledge of the advantage of model-driven programming toward infrastructure automation, the utility and functions of network test tools & simulation, the details and benefits of a CI/CD pipeline within infrastructure automation, as well as the fundamentals of infrastructure as code. It is also recommended to identify the workflows that are automated with a Python script utilizing Cisco APIs by an Ansible playbook & by a bash script. Moreover, one’s skills in comparing controller-level to device-level management are required.
- Network Fundamentals (15%)
This objective evaluates your expertise in performing a basic network topology plan with the elements, such as routers, firewalls, switches, port values, and load balancers. You need to demonstrate your knowledge of the purpose & utility of MAC addresses, VLANs, IP addresses, gateways, subnet mask/prefix, and routes, as well as your understanding of the function of common networking elements, IP services, and management, data & control levels in a network device. Additionally, the learners should be good at recognizing common protocol port conditions, identifying the reason for application connecting issues, and explaining the influence of network constraints on applications.
Holding the Cisco Certified DevNet Associate certification, you can see your career moving forward because the companies are ready to pay more to the certified individuals. There are many positions that you can apply for, some of which include a Software Developer, an Application Developer, a Network Engineer, an IT Specialist, a Senior Technical Support Technician, an IT Support Specialist, and a Cisco Route Switch Engineer, among others. With this certificate under your belt, you can start to earn about $70,000-$105,000 per annum.
