Difficulty: MediumConfigure Azure Load Balancer

You are planning to deploy a public Azure Load Balancer named LB1 to distribute incoming traffic across three virtual machines named VM1, VM2, and VM3. The virtual machines are deployed in different Availability Zones within the same virtual network.

You need to configure the load balancer and its frontend IP address.

Which two actions should you perform? Select two.

  1. Create a Standard SKU Azure Load Balancer.Answer
  2. Create a Standard SKU public IP address.Answer
  3. C
    Create a Basic SKU Azure Load Balancer.
  4. D
    Create a Basic SKU public IP address.

Answer

Create a Standard SKU Azure Load Balancer and a Standard SKU public IP address.
To support virtual machines deployed across different Availability Zones, a Standard SKU Load Balancer must be deployed. In addition, the SKU of the frontend public IP address must match the SKU of the load balancer, which requires creating a Standard SKU public IP address.

Step-by-Step Solution

1
Analyze the deployment topology of the backend virtual machines.
The virtual machines are deployed in different Availability Zones within the same virtual network.
This determines the minimum SKU capabilities required for the load balancer backend pool.
2
Select the load balancer SKU that supports the VM topology.
Standard SKU Azure Load Balancer.
Basic SKU load balancers do not support backend pools spanning multiple Availability Zones, whereas Standard SKU load balancers do.
3
Determine the required SKU for the frontend public IP address.
Standard SKU public IP address.
Azure Load Balancers require that the frontend IP configurations use a SKU matching the load balancer SKU itself. Therefore, a Standard SKU load balancer requires a Standard SKU public IP.
