What Is A Docker Certification?
There is actually only one certification associated with Docker, namely Docker Certified Associate Exam (DCA). The DCA certification is the only IT certification that covers everything from writing Docker files to managing Kubernetes clusters. Not for beginners, but for professionals with at least 6-12 months of Docker experience.
To get a Docker certificate, you must pass an exam administered by the DCA. The exam consists of 55 questions, of which 13 are multiple choice questions and 42 are multiple choice questions (DOMC). They must be answered within 90 minutes. After passing the test, the Docker certificate is valid for two years. You can get the energy to stay active.
What Do You Need To Know To Pass The Docker Certified Associate Exam?
In addition to having 6-12 months of experience working with Docker, you should be an expert in the following areas:
Container Integration:
You need to know how to deploy Docker containers and the various tools that help automate the process. Skills tested included: setting up and closing stream clusters; executing the compilation file for the application; running bag; to operate, store and multiply; Problem Solving; and communication between Docker and legacy systems.
Create and Manage Images:
So, you need to know how to create an image in a Docker file, manage it with CLI commands, layer, tag and delete an image, and work with the image registry.
Installation and Configuration:
This part of the exam requires you to know how to install Docker on different platforms, drivers, manage user and group creation, monitor growth and manage reviews the customer/distributor, and access the registry.
Security and Networking:
Drivers connecting containers. The system requires encryption via Mutual Transport Layer Security (mLTLS). Therefore, to eliminate this testing phase, you need to know not only how to use mlTS, but also how to configure the network for the developer. HTTP with HTTPS load balancing, and implements Docker machines, swarms and image storage.
Storage and Volumes:
Part of this exam requires you to understand how the Docker storage system works, including creating volumes to store user information, using drivers and strings, using object stores and storage blocks, cleaning . load unused images and save data using statistics.
Docker Editions:
You should be aware of the four editions of the Docker platform: Pro, Team, Business and Enterprise. Not only do you need to know the limitations of each edition for the software, but you also need to know what operating systems each server can run and communicate with.
Docker Certified Associate Exam Programs
Many websites act as providers of DCA certification exams, but others offer exam preparation through online courses, how-to videos, and practice tests. Here are the top five Docker certification sites to help you prepare for the DCA certification exam:
Course Covered By Docker Certified Associate Exam
Docker supplies DCA certification (administered by auditing), which helps confirm your knowledge and expertise in application integration with Docker. In the exam, in addition to your knowledge of Container Orchestration, you must have a working knowledge of Docker Enterprise Edition and Docker Swarm. By passing this test, you have proven that you can install and configure Docker-powered applications and this is an important benchmark for your IT skills.
Image Creation, Registry and Management
Image creation, management and registration count for about 20% of your total score on the DCA exam. All Docker containers are based on images, a block of embedded applications. The image is an executable package that contains everything you need to run your application.
For The Docker Certified Associate Exam, The Content Will Include:
- Docker file Options
- Creating Images using Docker file
- Image Management using CLI commands
- Docker Image Layers
- Deploying, Configuring and Logging into Registry
- Pushing, Signing and Pulling Images from the Registry
- Image Deletion
- Tagging Images
Installation and Configuration
This is considered the most important part of the entire DCA analysis. While installation and configuration will account for 15% of your total score, it should be noted that in the real world, a deep understanding of these concepts is always useful.
- Docker Engine Upgrade
- Install Docker Engine on different platforms
- Log Drivers
- Creation of users and groups, user management
- Growth Requirements
- Client-server authentication to access the image registry
Security & Networking
Each network and security contributes 15% to the total score. Networking in Docker involves connecting containers using drivers. To better understand networking for the DCA exam, you need to understand concepts such as:
- Docker Bridge Network Architecture for Developer Use
- log the problem
- Print the application port:
- Port Port and IP address ID
- Description of different types of network drivers
- Configure the Docker machine to use external DNS
- Load Balancing HTTPS HTTPS
- Traffic patterns on the Docker network
- Install services on the Docker network
The DCA security core includes all content related to authentication, encryption and transport security generally. This chapter includes:
- Make sure the images pass security checks
- The photo signing process
- Docker Content Trust
- Docker Machine Security
- Mechanical stability
- Distinguish between UCP employees and managers
- Mutual Transportation Security (MTLS).
- Using external certificates in the Docker Universal Control Plane
Storage and Volumes
This chapter makes up about 10% of your total grade. Volumes provide a way to store information in Docker. For the DCA Associate exam you are expected to understand:
- How to quickly make a scroll
- The difference between rolling and retaining supports
- Drivers and their most appropriate usage patterns
- Using the mapper tool
- Storage vs Storage Storage Blocks
- File format in layers
- Continuous security in Docker
- Deletes unused images
- Cluster Security
Docker Certified Associate Exam Enterprise Edition
Docker Enterprise Edition (EE) is designed for applications with critical deployments. It offers you a tailor-made solution, complete with advanced baggage management, security checks and application registration and monitoring. This version can be installed on all server operating systems, including Red Hat Enterprise Linux (RHEL), Ubuntu, Oracle Linux, Windows Server 2016, and SUSE Linux Enterprise Server (SLES). It is also available for cloud providers, including Azure and AWS.
Docker Certified Associate Exam (DCA) Study Strategy
As you prepare to study for your DCA exam, it’s best to plan carefully to make sure you don’t miss any important topics so that you’re not overwhelmed by the amount of knowledge pouring in.
To keep you organized, you can divide all the research into three parts:
- The first is a lab setup that allows you to make presentations. This can be a Docker Command Line Interface (CLI) environment, a cloud platform such as AWS (if you have a subscription), or an online gaming environment that emulates the Docker CLI.
- The second assessment as part of your plan should include a series of practice tests that will help you become familiar with the types of Multiple Choice (DOMC) and Multiple Choice Question (MCQ) tests used in the test. To help you with this, Kode Kloud offers assessment questions, practice tests, and mock tests in MCQ and DOMC formats that will help you familiarize yourself with the certification exam.
- Finally, but most importantly, plans to consider significant resources for important research. Kode Kloud training classes provide an in-depth understanding of the DCA curriculum in a structured format. Such tutorials are also a good resource for understanding various Docker commands, options, and tips, which are often helpful for a better understanding of Docker.
- Make sure your approach to learning is more practical than formal so that you can solve real-world problems. Therefore, some questions on the DCA exam test your knowledge of careers, career opportunities, and shortcuts.
