by using Azure Resource Manager templatesWithin each domain are a variety of subtopics that we'll cover in greater detail throughout the course. We'll go through each domain, using each previous lesson as part of the foundation for the next topic. This way, you will not only be able to answer the questions on the exam successfully but also develop practical knowledge of how these pieces fit together and how you can design solutions to common problems faced in enterprises today. You'll get experience with hands-on labs to solidify your knowledge, and you can look forward to practice questions throughout the course to ensure you're ready to move on. With the word "cosmos" in it's name, we couldn't resist a solar system theme. To keep things interesting, each section starts with a little solar system trivia or other planetary chit-chat. You will also learn about your instructor's near-obsession with Pluto and it's demotion to dwarf status. Let's get started!
