About 300-910 Exam
The Cisco 300-910 DEVOPS qualification exam also known as Implementing DevOps Solutions and Practices using Cisco Platforms has been prepared to measure and test a candidate’s knowledge and understanding of DevOps practices. This is especially concerning an area such as deployment automation which allows automated configuration, scalability, and management of cloud microservices as well as infrastructure process on the Cisco platforms. This exam helps you obtain two certifications: one of specialist and one of professional levels.
Before opting for the exam, candidates are expected to have 3-5 years of hands-on experience implementing and developing apps built on Cisco platforms.
As for the exam details, the DEVOPS 300-910 is a 90-minute proctored test that is capable of earning you two different Cisco certifications such as the Cisco Certified DevNet Specialist – DevOps and the Cisco Certified DevNet Professional. However, in the case of the last-mentioned accreditation, the exam is one of the 8 concentration tests offered to the applicant. And in addition to this, s/he must necessarily pass the 350-901 DEVCOR core exam.
Exam 300-910 involves a set of six knowledge areas that also contain various subtopics with a particular percentage of the total exam score. Therefore, it is necessary for every candidate who wants to pass the Cisco 300-910 well to get familiar with everything under the given topics:
- CI/CD Pipeline
This domain is concerned with the areas where candidates get to know and understand the concepts and characteristics of deploy/build tools including Drone, Jenkins, or Travis CI. They also have to know all that is needed in the implementation of a CI/CD pipeline, how to troubleshoot issues through CI/CD pipeline such as pipeline issues, tool incompatibility, and code-based failures. Furthermore, candidates should understand the essentials of tests for CI/CD pipeline integration and strategy of release deployment like rollbacks, canary, and blue/green. Besides, they have to understand how to do a diagnosis of code dependencies management issues such as tool chain, API, and libraries. Importantly, the percentage of questions from this domain is 20%.
- Packaging and Delivery of Applications
This domain takes up 15% of the whole exam. In it, generally, candidates will demonstrate their understanding of the steps involved in containerizing an application as well as those involved in deploying multiple microservice apps. Moreover, candidates will show the best ways to evaluate diagrams of container architecture and microservices specifically based on business and technical requirements including stability, performance, security, and cost. The applicants should also be familiar with the best paths to handle configuration items, secrets, and application parameters. Other things they will get to learn here include how to design a Docker file as well as how to describe the usage of golden images.
- Automating Infrastructure
This is another category that covers 20% of the final test. Here, candidates are meant to understand the practical processes involved in integrating DevOps practices into the structure of any organization. Test-takers are also expected to know about the automation of infrastructure services like Puppet, Terraform, Ansible, and Chef using configuration management tools. They should also understand the construction of an Ansible playbook, a Terraform configuration process, the benefits and practice of Infrastructure as Code, as well as the pre-check validation procedure of the network state & application infrastructure in a CI/CD pipeline. Every candidate is also expected to have necessary concepts as regards extending DevOps practices for the sake of NetDevOps, and to know the requirements for scaling the service or application.
- Cloud and Multicloud
Containing 15% of the 300-910 exam, in this part candidates need to understand necessary details regarding Kubernetes including concepts, objects, and applications as well as possess skills of how to utilize them. According to this section, candidates are also expected to know how to effectively interpret the pipeline, how to affirm the success of an app usage, how to utilize an app in multiple environments, and how to track costs when utilizing the public cloud. They must know the advantages of infrastructure as code concerning public cloud consuming, as well as how best to juxtapose the strategies of cloud services.
- Metrics, Logging, Monitoring
This is where candidates prove the knowledge of log and metric systems and everything related to them. In this area, applicants should not only understand what it entails to troubleshoot applications for possible issues but also understand what is needed in the implementation of the reporting system and log collection. They also should have a good grip of the chaos engineering principles, as well as how to create Python scripts needed to deploy APIs, and how to improve visibility of application performance and health. Certain Kubernetes capabilities are also a part of this domain that takes 20% of the Cisco exam.
As the name suggests, this domain generally involves the security domain, especially regarding infrastructure and application during the processes of testing and production in a CI/CD pipeline. Questions of this exam part are also concerned life cycle of software development and represent 10% of the whole test.
Preparing for the Exam
In studying towards passing this exam, candidates are expected to complete the official Cisco course named Implementing DevOps Solutions and Practices Using Cisco Platforms (DEVOPS) v1.0. Through this training, the candidates will get to learn the essentials of how to integrate Kubernetes and Docker to develop flexibility and advanced capabilities in the application deployment process. As well, the candidates will master various necessary skills in areas such as automation, enhance scalability, and container orchestration.
As a Cisco-certified DevNet specialist, you automatically validate your knowledge as well as your skillset, particularly in application design, software development, and the automation field. Through this, you attain more recognition and credibility both on the personal and the organizational levels. Moreover, the chances of getting better salary and promotion opportunities, and even getting more in-demand jobs, are wider for certified specialists. Also, as found via the Glassdoor.com website, a DevNet specialist is capable of working in the capacities of Web Software Developer and earning $62-67k per year, or Application Programmer with an average salary of $52-56 per year, Senior Software Engineer ($89-96 per year), and more.
