Zorluk: OrtaConfigure VMs for High Availability

NovaHealth plans to deploy a new patient records application consisting of 33 virtual machines in the West US 3 region. The deployment must guarantee a virtual machine uptime SLA of at least 99.99%99.99\% and protect the application against datacenter-level failures. You need to configure the high availability solution for the virtual machines. Which two actions should you perform? (Select two.)

  1. Deploy the virtual machines across two or more Availability Zones in West US 3.Cevap
  2. B
    Deploy the virtual machines within a single Availability Set.
  3. Deploy an Azure Standard Load Balancer to distribute traffic to the virtual machines.Cevap
  4. D
    Deploy an Azure Basic Load Balancer to distribute traffic to the virtual machines.

Cevap

Deploy the virtual machines across two or more Availability Zones in West US 3, and deploy an Azure Standard Load Balancer to distribute traffic to the virtual machines.
To satisfy a 99.99%99.99\% virtual machine uptime SLA and protect against datacenter-level outages, virtual machines must be distributed across two or more Availability Zones. Because the virtual machines are distributed across zones, an Azure Standard Load Balancer must be deployed to distribute traffic, as the Basic SKU load balancer does not support zonal backend pools.

Adım Adım Çözüm

1
Analyze the SLA and high availability requirements.
The target SLA is 99.99%99.99\%, and the application must be protected against datacenter-level failures.
This requirement determines whether to use Availability Sets (which offer 99.95%99.95\% SLA and protect only against local hardware failures) or Availability Zones (which offer 99.99%99.99\% SLA and protect against datacenter outages).
2
Select the appropriate virtual machine deployment target.
Select Availability Zones as the deployment target.
Deploying virtual machines across two or more Availability Zones in the West US 3 region satisfies both the 99.99%99.99\% SLA and the datacenter-level protection requirements.
3
Identify the load balancing requirement for the multi-zone deployment.
Select an Azure Standard Load Balancer.
An Azure Standard Load Balancer is required because Basic Load Balancers do not support backend pools containing zonal virtual machines.
