1Design and Implement Core Networking Infrastructure

• 1.1Virtual Networks (VNet) and Subnets

  Understand the virtual network (VNet) as the foundation of Azure networking, plus subnets, address space (CIDR), and VNet peering. The starting point for "core networking infrastructure" in AZ-700.

• 1.2Name Resolution in Azure (DNS)

  Understand public DNS (hosting public domains), private DNS zones (name resolution inside a VNet), and Azure-provided default resolution. Resolving names to addresses is fundamental to networking.

• 1.3Load Balancing (Load Balancer, App Gateway, Front Door)

  Understand how to choose among Azure load balancing services that distribute traffic to backends: Azure Load Balancer (L4), Application Gateway (L7, regional), Front Door (L7, global), and Traffic Manager (DNS-based).
