Network Virtual Appliance — Microsoft Azure Solutions Architect (AZ-305) Practice Questions
A network virtual appliance (NVA) is a virtual machine that performs network functions such as firewalling, intrusion detection, WAN optimization, or load balancing within an Azure virtual network. AZ-305 candidates must understand when to deploy an NVA versus using native Azure services like Azure Firewall, and how to route traffic through an NVA using user-defined routes. High availability for NVAs typically requires deploying multiple instances behind a load balancer or using Azure Route Server for dynamic routing. Selecting the right NVA architecture is a common design question on the exam.
