Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

What is a paired region in Azure?

1. A geographical location with two datacenters

2. A group of resource groups

3. A service connection between services

4. A collective term for virtual networks

The correct answer is: A geographical location with two datacenters

A paired region in Azure refers to a geographical location that contains two datacenters, which are linked together for redundancy and high availability. The primary reason for this design is to ensure that if one datacenter experiences an outage or issue, the other can take over seamlessly, providing resilience for services and data. Azure regions are paired for various reasons, including data residency, disaster recovery, and compliance requirements. Each paired region works together to support the availability and reliability of applications and services hosted on Azure. This configuration aids in scenarios such as backups, data replication, and failover processes. The other options describe different concepts not related to the specific definition of a paired region. A group of resource groups refers to a way of organizing resources in Azure for management purposes, while a service connection pertains to connectivity between different Azure services. Lastly, the term for virtual networks refers to a networking construct within Azure that allows connectivity among various resources rather than denoting a geographical concept.
