Microsoft AZ-305 Practice Exam

Azure Virtual Network primarily serves the purpose of enabling a private network in the cloud. It allows users to create isolated environments for their Azure resources, facilitating secure communication between different services and applications. Through Azure Virtual Network, you can define a range of IP addresses, subnets, and network security groups, giving you control over traffic flow and enhancing security. This allows virtual machines, Azure services, and on-premises resources to communicate securely and efficiently within the defined network boundaries.

The other choices, while relating to various Azure services, do not accurately reflect the primary function of Azure Virtual Network. For instance, providing a dedicated server for data analytics is more aligned with Azure services such as Azure Synapse Analytics or Azure Databricks, which specialize in data processing and analytics rather than networking. Processing user authentication for applications pertains to Azure Active Directory and similar services focused on identity management, and managing cloud costs is more related to Azure Cost Management tools rather than the networking capabilities of Azure Virtual Network. Thus, option A stands out as the definitive purpose of Azure Virtual Network.
