An organization is designing a multi-tier web application on Azure. The application's backend web tier consists of Azure Virtual Machines that require a cumulative compute SLA of and low-latency network communication between the virtual machines to support high-throughput in-memory caching. You need to design the compute infrastructure. Which two configurations should you include in the design? (Each correct answer presents part of the complete solution.)
- Deploy the virtual machines across two or more Availability Zones in the region.Answer
- Deploy the virtual machines in a single Proximity Placement Group.Answer
- CDeploy all virtual machines within a single Availability Zone using an Availability Set.
- DDeploy the virtual machines as Azure Spot VMs in a single scale set.
Answer
To meet the requirements, the design must include deploying the virtual machines across multiple Availability Zones to achieve the SLA, and placing them in a single Proximity Placement Group to ensure low-latency communication.
To meet the SLA requirement, virtual machines must be deployed across two or more Availability Zones in the same region. To meet the low-latency placement requirement, a Proximity Placement Group should be used to physically group the virtual machines.
Step-by-Step Solution
Key Concept
Azure virtual machine high availability design using Availability Zones for SLA and Proximity Placement Groups for low latency.
