Implementing Microsoft Azure Architect Technologies: AZ-303 Exam Prep and Beyond - Second Edition

By: Brett Hargreaves, Sjoukje Zaal

Overview of this book

From designing solutions on Azure to configuring and managing virtual networks, the AZ-303 certification validates your knowledge and skills for all this and much more. Whether you want to take the certification exam or gain hands-on experience in administering, developing, and architecting Azure solutions, this study guide will help you get started. Divided into four modules, this book systematically takes you through the wide range of concepts and features covered in the AZ-303 exam. The first module demonstrates how to implement and monitor infrastructure. You'll develop the skills required to deploy and manage core Azure components such as virtual machines, networking, storage, and Active Directory (AD). As you progress, you'll build on that knowledge and learn how to create resilient and secure applications before moving on to working with web apps, functions, and containers. The final module will get you up to speed with data platforms such as SQL and Cosmos DB, including how to configure the different high availability options. Finally, you'll solve mock tests and assess yourself with the answers provided to get ready to take the exam with confidence. By the end of this book, you'll have learned the concepts and techniques you need to know to prepare for the AZ-303 exam and design effective solutions on Microsoft Azure.

User-defined routes

When you create subnets, Azure creates system routes that enable all the resources in a subnet so that they can communicate with each other. Every subnet has a default system route table, which contains the following minimum routes:

  • Local VNet: This is a route for resources that reside in the VNet. For these routes, there is no next hop address. If the destination IP address contains the local VNet prefix, traffic is routed there.
  • On-premises: This is a route for defined on-premises address spaces. For this route, the next hop address will be the VNet gateway. If the destination IP address contains the on-premises address prefix, traffic is routed there.
  • Internet: This route is for all the traffic that goes over the public internet, and the internet gateway is always the next hop address. If the destination IP address doesn't contain the VNet or on-premises prefixes, traffic is routed to the internet using Network Address Translation (NAT).
