Nebula Logistics plans to deploy a new web application in the North Europe region. The application will run on two new virtual machines named VM-Web1 and VM-Web2. The deployment must meet the following requirements:
- Guarantee a virtual machine uptime SLA of at least $99.99\%$ .
- Protect the application against datacenter-wide failures.

Which two configurations should you implement? (Select two.)

Deploy VM-Web1 to Availability Zone 1 and VM-Web2 to Availability Zone 2.Answer
Associate the virtual machines with a Standard Load Balancer.Answer
C
Deploy VM-Web1 and VM-Web2 to a new Availability Set.
D
Associate the virtual machines with a Basic Load Balancer.
E
Create an Availability Set configured across Availability Zone 1 and Availability Zone 2, and place both virtual machines in the set.

Answer

Deploying the virtual machines across different Availability Zones and associating them with a Standard Load Balancer.

To guarantee an SLA of

99.99\%

for virtual machine connectivity, instances must be deployed across two or more Availability Zones in the same region. A Standard Load Balancer is required because it supports zone-redundant backend pools that can span multiple Availability Zones to distribute traffic to the virtual machines.

Step-by-Step Solution

Evaluate the SLA target of

99.99\%

for virtual machine uptime.

Determine that an uptime SLA of

99.99\%

requires virtual machines to be distributed across two or more Availability Zones in the same region, as Availability Sets only guarantee up to a

99.95\%

SLA.

Availability Zones provide independent power, cooling, and networking infrastructure, protecting the application from datacenter-wide outages.

Select the correct zone placement configuration for VM-Web1 and VM-Web2.

Configure VM-Web1 to be deployed in Availability Zone 1 and VM-Web2 in Availability Zone 2.

This configuration ensures that the virtual machines are physically separated into distinct datacenters within the region.

Select the load balancer tier required to distribute traffic to the zone-distributed virtual machines.

Select a Standard Load Balancer and configure its backend pool to include both VMs.

Standard Load Balancer supports zone-redundant backend pools that can span across multiple Availability Zones, which is a requirement for load-balancing across zones.
