Overview of this book

Designing and Implementing Microsoft Azure Networking Solutions is a comprehensive guide that covers every aspect of the AZ-700 exam to help you fully prepare to take the certification exam. Packed with essential information, this book is a valuable resource for Azure cloud professionals, helping you build practical skills to design and implement name resolution, VNet routing, cross-VNet connectivity, and hybrid network connectivity using the VPN Gateway and the ExpressRoute Gateway. It provides step-by-step instructions to design and implement an Azure Virtual WAN architecture for enterprise use cases. Additionally, the book offers detailed guidance on network security design and implementation, application delivery services, private platform service connectivity, and monitoring networks in Azure. Throughout the book, you’ll find hands-on labs carefully integrated to align with the exam objectives of the Azure Network Engineer certification (AZ-700), complemented by practice questions at the end of each chapter, allowing you to test your knowledge. By the end of this book, you’ll have mastered the fundamentals of Azure networking and be ready to take the AZ-700 exam.

Designing and implementing cross-network connectivity over ExpressRoute

By default, ExpressRoute connections route network traffic only between connected remote networks and Azure VNets. For example, an organization has two branch offices connected to Azure networks (as shown in Figure 6.26), as follows:

  • A remote network in London that connects to an Azure network in “UK South” via an ExpressRoute circuit in London
  • A remote network in New York that connects to an Azure network in “East US” via an ExpressRoute circuit in New York

The result of this connectivity is that the 10.30.0.0/16 network can communicate with the 10.10.0.0/16 network, and the 10.40.0.0/16 network can communicate with the 10.20.0.0/16 network. However, no other cross-network communication will be possible:
