Microsoft Azure Solutions Architect Expert AZ-305 Practice Question

Your company is migrating a three-tier .NET application to Azure. The web and application tiers will run on eight Windows Server virtual machines (VMs).

Business requirements:

  • Achieve an SLA of at least 99.99% VM connectivity uptime.
  • Maintain service availability if any single Azure availability zone in the selected region becomes unavailable.
  • Minimize additional cost and administrative overhead.

Which deployment option for the web and application tiers should you recommend?

  • Use an Azure Virtual Machine Scale Set with a single placement group and set platformFaultDomainCount to 2.

  • Create an Azure Virtual Machine Scale Set configured for zone redundancy, distributing the eight VMs across at least two availability zones in the region.

  • Deploy two identical environments in separate Azure regions, each using availability sets, and route traffic with Azure Traffic Manager (priority routing).

  • Place all VMs in an Azure availability set with two fault domains and five update domains inside one availability zone.
