An organization is designing a high availability compute solution in Azure for a legacy line-of-business application. The application will run on two virtual machines. The organization has the following requirements:
- The virtual machines must be protected against a datacenter outage within the Azure region.
- The solution must achieve a virtual machine uptime SLA of 99.99%.
Which two configurations should you recommend to meet these requirements? (Select two.)
- Deploy the virtual machines as individual instances across different Availability Zones, placing one in Zone 1 and the other in Zone 2.Cevap
- Deploy the virtual machines using a Virtual Machine Scale Set (VMSS) in Flexible orchestration mode spread across multiple zones.Cevap
- CDeploy both virtual machines within a single Availability Zone.
- DDeploy the virtual machines in an Availability Set.
Cevap
Deploy the virtual machines as individual instances across different Availability Zones, and deploy the virtual machines using a Virtual Machine Scale Set in Flexible orchestration mode spread across multiple zones.
To achieve a 99.99% Virtual Machine uptime SLA and protect against datacenter outages in Azure, virtual machines must be distributed across multiple Availability Zones. Individual VMs placed in different zones (such as Zone 1 and Zone 2) or a Virtual Machine Scale Set configured with Flexible orchestration and spread across zones satisfy this requirement.
