Microsoft Azure Fundamentals (AZ-900)Describe Azure architecture and servicesMedium
A company is planning to migrate its on-premises virtual machines to Azure. They need a solution that provides network isolation between their Azure resources and their on-premises network, while also allowing secure communication. Which Azure networking component is essential for establishing this private and secure connection?
- AAzure Virtual Network (VNet)
- BAzure Traffic Manager
- CAzure DNS
- DAzure Content Delivery Network (CDN)
Show answer & explanationAnswer & explanation
Correct answer: A. Azure Virtual Network (VNet)
An Azure Virtual Network (VNet) is the fundamental building block for your private network in Azure. It enables many types of Azure resources, such as Azure Virtual Machines (VMs), to securely communicate with each other, the internet, and on-premises networks.
Why the other options are wrong
- B. Azure Traffic Manager is a DNS-based traffic load balancer, used for distributing traffic across endpoints, not for private network connectivity.
- C. Azure DNS provides domain name resolution, not network isolation or secure connectivity.
- D. Azure CDN is used to deliver web content efficiently to users globally, not for private network isolation.
Azure Virtual Network (VNet)
A private network in Azure that enables Azure resources to securely communicate with each other, the internet, and on-premises networks. It provides isolation and segmentation.
- Logical isolation for Azure resources.
- Enables secure communication between resources.
- Supports hybrid connectivity with on-premises networks.
- Provides control over IP addressing, DNS, and routing.
Memory trick: VNet is your private network in the cloud.
