Orion FinTech plans to deploy a new web portal consisting of two virtual machines named VM-Web1 and VM-Web2 in the Japan East region. The deployment must guarantee a virtual machine SLA of at least $99.99\%$ and protect the application from datacenter-wide failures. You need to configure the compute and load balancing infrastructure. Which two options should you select? (Select two.)

Deploy VM-Web1 and VM-Web2 in separate Availability Zones.Answer
B
Deploy VM-Web1 and VM-Web2 within a single Availability Set.
Deploy an Azure Standard Load Balancer to distribute traffic to the virtual machines.Answer
D
Deploy an Azure Basic Load Balancer to distribute traffic to the virtual machines.

Answer

Deploy the virtual machines in separate Availability Zones and deploy an Azure Standard Load Balancer to distribute traffic.

To meet the

99.99\%

SLA requirement and protect against datacenter-wide outages, virtual machines must be deployed across separate Availability Zones. Additionally, routing traffic to these VMs across zones requires an Azure Standard Load Balancer, as the Basic SKU is not zone-aware.

Step-by-Step Solution

Analyze the high availability and SLA requirements.

The requirement demands a

99.99\%

SLA and protection against datacenter-wide outages.

This level of resilience can only be met by distributing VMs across physically separate datacenter locations, which corresponds to Azure Availability Zones.

Select the VM deployment target.

Select separate Availability Zones for VM-Web1 and VM-Web2 instead of an Availability Set.

Availability Sets limit VMs to a single datacenter (SLA

99.95\%

), whereas Availability Zones distribute them across datacenters (SLA

99.99\%

Determine the load balancer SKU required for the zonal deployment.

Choose a Standard Load Balancer.

Standard Load Balancer supports backend pools spanning multiple Availability Zones and provides zone redundancy, whereas the Basic Load Balancer does not support zonal deployments.
