Practice Test Introduction

Before you begin the practice test, take a moment to familiarize yourself with the practice test portal. Once the lecture is completed, you will be directed to the lab environment where you'll complete various hands-on exercises.

Lab Environment Overview

Click the start button to load the lab environment. Allow a moment for the lab to initialize—typically less than 30 seconds, though occasionally it may take a few minutes.

Once loaded, you will see two main sections:

• Quiz Portal (Left Side): Hosts your test questions.
• Live Terminal (Right Side): Where you execute commands. This terminal might be a Linux shell for Linux, shell scripting, or Git tasks; a Docker host for Docker tasks; or a Kubernetes control plane for Kubernetes tasks. You can run commands here to interact with and configure the system.

Below is an image illustrating the practice test interface:

Structure of the Practice Test

The lab is divided into two parts:

1. Terminal: Use this section on the right to run commands and interact with the system (e.g., view and configure a Kubernetes cluster).
2. Quiz Portal: Located on the left, this portal contains practice test questions grouped by topic. Each practice test includes between 5 to 15 questions. The total number of questions is shown at the top, and each question is marked as you progress.

Question Types

The test includes a variety of question types for a comprehensive learning experience:

• Environment-Based Questions: Find information within the lab environment to select the correct answer.
• Configuration Tasks: Modify the environment by deploying Pods, services, or other components, then verify the changes.
• Specification Matching: Given a configuration specification (spec), create a matching configuration using the provided editors (e.g., the vi editor).
• Multiple-Choice Questions: Some questions are scenario-based to test your conceptual understanding. Note that these might not appear on the actual certification exam.

If a configuration does not exactly match the given specification, adjust your settings precisely. You can skip questions by clicking the skip button at the top; however, once skipped, these questions cannot be revisited due to the fixed question sequence.

Accessing Web Applications

For certain deployments, you might have a web portal link available above the terminal. This link is provided if the application features a web interface. For instance, when exposing a service, you might run the following command:

root@controlplane:~# kubectl expose pod nginx --port 80 --type NodePort
service/nginx exposed
root@controlplane:~#

If you need an additional terminal window, use the designated button at the top.

Retaking the Test and Session Guidelines

You can retake these tests as many times as needed until you feel confident. However, remember:

• The lab environment is temporary and will expire after one hour (or as specified).
• Refreshing the lab window or experiencing temporary connectivity issues should return you to the same environment.
• Extended browser closures or lengthy idle periods may result in the lab being automatically terminated. In such cases, you will need to restart a new lab session from the beginning.

Below is an image that reminds you of the temporary nature of the lab environment:

Practice and Learning

These practice tests are designed not only to assess your skills based on the course lecture but also to help you gain essential hands-on experience. Some questions may cover topics beyond the lecture material, so always refer to the documentation and search for solutions if you are stuck. The hints and solutions panel, visible with each question, is provided to guide you.

If any task or question remains unclear, please reach out for further assistance. The goal is to encourage you to read the documentation, find necessary information, and apply it successfully.

Good luck with your practice test and exam preparation!
