Question

You need to ensure that the services running on the virtual machines are available if a single data center fails. You deploy the virtual machines to two or more resource groups. Does this meet the goal?

a) True
b) False

Answer 1

Deploying virtual machines to multiple resource groups does not meet the goal of ensuring service availability in case of a data center failure. Instead, virtual machines should be deployed across different Azure availability zones or regions for better fault tolerance and high availability.

Step-by-step explanation:

The deployment of virtual machines to two or more resource groups does not guarantee the availability of services if a single data center fails. While distributing the virtual machines across multiple resource groups can help with organizational and management purposes, it does not provide the necessary redundancy and high availability in case of a data center failure.

To ensure service availability in the event of a data center failure, you should deploy the virtual machines in different Azure availability zones or regions. Azure availability zones are physically separate data centers within an Azure region, offering better fault tolerance, while Azure regions are geographically dispersed locations with independent power, cooling, and networking infrastructure.

By deploying virtual machines across multiple availability zones or regions, you can achieve a higher level of resiliency and ensure the availability of services even if a single data center fails.
