Question 1.A company has a local network with several servers. The company plans to migrate all servers to Azure. John was asked to provide a solution to ensure that some of the servers would be available in the event that a single Azure data center goes offline for an extended period. What should Juan do in this case?

1. Fault tolerance
2. elasticity
3. scalability
4. short waiting time

Correct answer:Fault tolerance

Explanation:Fault tolerance is the property that allows a system to continue to function correctly in case of failure (or one or more internal failures) of some of its components. Availability zones extend the control plane to maintain the availability of applications and data on virtual machines. The physical separation of availability zones within a region protects applications and data from data center failures. Additionally, with Availability Zones, Azure offers a 99.99% uptime SLA for virtual machines. Therefore, by developing solutions that use zone-replicated virtual machines, we can protect applications and data from being lost in a data center.
