Implementing Secure VNet Peering Between Departmental Networks
As the lead network administrator for a growing enterprise, you will establish secure, private network communication between two departmental Azure Virtual Networks. Starting with a pre-deployed HR environment containing an Azure SQL Server, you will create and peer a Finance Virtual Network to bridge the two departments. You will then implement advanced security controls using Network Security Groups (NSGs) to permit only specific SQL traffic while explicitly denying all other inter-departmental communication. Finally, you will configure a custom route table to prevent sensitive workloads from accessing the public internet. By the end of this lab, you will have gained practical experience in the multi-layered networking skills required to connect and secure private resources in a peered Azure environment.

Challenge
Create the Finance VNet and establish VNet peering with the HR environment
Deploy a Finance Virtual Network with a non-overlapping address space and configure a bidirectional peering link to the pre-existing HR VNet to establish a private, low-latency network route between the two departmental environments.
-
Challenge
Restrict inter-VNet traffic using Network Security Groups
Configure inbound and outbound NSG rules on both departmental subnets to explicitly permit SQL traffic on port 1433 while denying all other cross-VNet communication, enforcing the principle of least privilege across the peered connection.
-
Challenge
Control HR subnet routing to block internet egress
Create and associate a custom route table with the HR subnet that overrides Azure's default internet system route, dropping all internet-bound traffic at the routing layer while preserving internal SQL connectivity across the peered VNets.
Real skill practice before real-world application
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
