📖 About this Domain
This domain focuses on controlling network traffic flow within Azure Virtual Networks and to external networks. You will implement user-defined routes (UDRs), Azure Route Server for dynamic routing, and manage traffic within Azure Virtual WAN. The domain also covers implementing Azure DNS for name resolution.
🎓 What You Will Learn
- You will learn to implement user-defined routes (UDRs) in a route table to override Azure's default system routes.
- You will learn to deploy and configure Azure Route Server to enable dynamic routing between your network virtual appliance (NVA) and your virtual network.
- You will learn to configure routing within an Azure Virtual WAN hub by creating and managing hub route tables.
- You will learn to design and implement Azure DNS, including private zones for VNet name resolution and public zones for external services.
🛠️ Skills You Will Build
- You will build skills to force tunnel traffic to an NVA by creating custom routes and associating route tables to subnets.
- You will build skills to configure BGP peering between an NVA and Azure Route Server for route exchange.
- You will build skills to manage traffic flow in a hub-and-spoke topology using Virtual WAN hub routing policies and route tables.
- You will build skills to configure split-horizon DNS using Azure DNS private zones and link them to virtual networks.
💡 Top Tips to Prepare
- Practice creating UDRs with different next hop types, such as VirtualAppliance, VirtualNetworkGateway, and Internet.
- Understand the role of ASN and BGP peering IP addresses when configuring Azure Route Server with an NVA.
- Get hands-on with Virtual WAN hub route tables, focusing on how route propagation and association direct traffic between connections.
- Master the configuration of Azure DNS private zones, including VNet links and auto-registration settings.
