Final answer:
The claim that a virtual network is confined to a single region is inaccurate. Virtual networks in cloud computing can be configured to span multiple regions to enhance application performance and ensure disaster recovery.
Step-by-step explanation:
The statement that a virtual network is scoped to a single region is false. Virtual networks, especially in the context of cloud services like Microsoft Azure or Amazon Web Services (AWS), can span multiple regions. This is often used for creating highly available and resilient applications that are geographically distributed to enhance performance and provide redundancy in case of regional outages.
A virtual network allows cloud resources such as virtual machines and databases to securely communicate with each other, the internet, and on-premises networks. Cloud providers offer solutions that enable these virtual networks to connect to networks in other regions, creating a globally distributed network infrastructure. For example, Microsoft Azure has the Virtual Network Peering feature that connects virtual networks within the same region or across different regions, known as Global VNet peering.
