About Cisco DevNet Associate Certification
Cisco offers loads of certifications that should help you in your career development, but one of the most popular options nowadays is none other than the Cisco DevNet Associate certificate. It proves your skills and expertise in developing as well as maintaining the apps that are built on the Cisco platforms.
To become a DevNet Associate, the potential candidates need to fulfill certain requirements and ace the Cisco 200-901 exam. This test evaluates your fundamental knowledge of the software development field and measures your ability to design for the Cisco platforms. Although there are no formal prerequisites for this path, it is recommended that anyone going for this certification has at least a year of experience in Python programming and software development. Besides that, you need to possess a solid understanding of the topics covered in the exam content.
The Cisco 200-901 exam is also known as 200-901 DEVASC and is the only test required for this associate-level path. It is 120 minutes long and contains about 100 questions that you need to clear. All the items are presented in various formats, including fill-in-the-blank, testlet, and multiple choice, and are available in the English or Japanese language depending on your choice during the registration process. The minimum passing score for the Cisco exams is usually 825 points, so keep in mind that you should try to earn more. The test costs $300, and this is the price that doesn’t include any local taxes.
To successfully complete the 200-901 DEVASC test and get the passing score, you should prepare well and use authentic study materials. Therefore, you should visit the Cisco website where you can find the official training course, known as Developing Apps & Automating Workflows using Cisco Core Platforms. It is a self-paced option that will help you cover all the topics of the exam. Once it is completed, the learners should evaluate their knowledge with some practice tests. This way, they can ensure that they achieve the best possible score.
Learning the topics is what any interested candidate should do regardless of his/her current level of knowledge. You may have some prior theoretical or even practical expertise, but there are always some questions in the test that can cover the details you still don’t know. That is why it is important to be prepared for the following domains if you want to Cisco 200-901 and obtain the associated certification.
- Network Fundamentals – 15%
In this section, the potential candidates need to have knowledge of the purpose of MAC addresses and VLANs as well as their use cases. Also, they are required to know the purpose and usage of IP addresses, subnet mask/prefix, gateways, and routes as well as the function of the common networking components. They include routers, switches, load balancers, and firewalls. This area includes the details of the network topology diagram with port values, routers, load balancers, firewalls, and switches. Your skills in recognizing the common protocol port values will be evaluated as well. Besides that, you should have knowledge of the function of data, control, and management planes in a network device and functionality of DNS, NAT, DHCP, SNMP, and NTP.
- Software Development & Design – 15%
Here, the individuals need to have the skills in comparing data formats, such as JSON, XML, and YAML, utilizing the common version control operations with Git, and comparing the software development methods, which include waterfall, lean, and agile. To be able to answer the questions from this topic, the students should know about the parsing of the common data format to Python data structures, advantages of version control, as well as the concepts of the test-driven development. A successful candidate also knows how to identify the advantages of common design patterns and which advantages to expect while organizing code into modules, classes, and functions/methods.
- Understanding & Use of APIs – 20%
This objective is all about the construction methods of the REST API requests, constraints when consuming APIs, and regular HTTP response codes that are associated with REST APIs. It is important to have a solid understanding of the common usage patterns, which are related to webhooks, and utilization cases related to the common API authentication mechanisms, including API keys, basic, and custom token. To deal with the questions from this part, you need to have the relevant skills in troubleshooting problems given the HTTP response code, API documentation, and request. Moreover, don’t forget to learn how to compare RPC, REST, asynchronous, and synchronous API styles.
- Cisco Platforms & Development – 15%
As for this module, you are required to be able to construct the Python scripts using Cisco SDK documentation. It is also essential for the applicants to know about the capabilities of the Cisco network management platforms, Cisco compute management platforms, Cisco collaboration platforms, Cisco security platforms, as well as APIs. They should be skillful enough to apply the concepts of model-driven programmability and identify the appropriate DevNet resources for the given scenarios.
- Application Deployment & Security – 15%
This subject area will test one’s skills in identifying the attributes of different application deployment models, constructing the Python unit tests, as well as using the Bash commands and Docker images in a local developer environment. Your skillset should also include the ability to identify app security issues that are related to the secret protection & encryption and principles of DevOps practices.
- Infrastructure & Automation – 20%
This is the last topic that you need to cover for the test to master the overall content. It includes the details of the value of model-driven programmability for infrastructure automation the components and benefits of the CI/CD pipeline in infrastructure automation. Furthermore, it contains the information about the principles of an infrastructure as a code, capabilities of the automation tools, and the use cases and roles of the test tools and network simulation. Knowing the identification process of the workflow being automated by a Python script, Ansible playbook, and bash script is also vital.
Once you have obtained the Cisco DevNet Associate certification, you will have the choice to apply for much better jobs and expect a higher salary. Nowadays, the companies know the value of the certified individuals, so they rarely pass on an opportunity to hire one. Some of the positions that you can pursue include a Software Developer, a DevNet Bootcamp Delivery Engineer, an Application Developer, a Network LAN/WAN Administrator, a Network Engineer, and so on. As for your future average salary, you will be able to earn $62,329 per year. The income of the certified specialists can even be up to $137,686 per annum, depending on their title and tasks.
