Zorluk: OrtaConfigure Azure Load Balancer

You are configuring a public Azure Load Balancer named LB-App to distribute incoming traffic across three virtual machines: VM-A, VM-B, and VM-C. The virtual machines are deployed in the same region, are connected to the same virtual network, and are not configured in an Availability Set or Virtual Machine Scale Set. You have already created a Basic SKU public IP address named IP-Web to serve as the frontend. You need to complete the load balancer configuration so that all three virtual machines can receive traffic. Which action should you perform?

  1. Deploy LB-App as a Standard SKU load balancer, create a Standard SKU public IP address for the frontend, and add the virtual machines to the backend pool.Cevap
  2. B
    Deploy LB-App as a Basic SKU load balancer, associate it with the existing IP-Web frontend, and add the virtual machines to the backend pool.
  3. C
    Deploy LB-App as a Standard SKU load balancer, associate it with the existing IP-Web frontend, and add the virtual machines to the backend pool.
  4. D
    Deploy LB-App as a Basic SKU load balancer, configure IP-Web as the frontend, and associate each virtual machine with a different subnet in the virtual network.

Cevap

Deploy the load balancer as a Standard SKU, create a Standard SKU public IP address for the frontend, and add the virtual machines to the backend pool.
Deploying the load balancer as Standard SKU and creating a Standard SKU public IP address is correct because Standard SKU load balancers support standalone virtual machines in their backend pool, and they require a matching Standard SKU frontend public IP address.

Adım Adım Çözüm

1
Analyze the backend virtual machine configuration.
The virtual machines are standalone instances (not in an Availability Set or Virtual Machine Scale Set).
Basic SKU load balancers require backend pool members to be in the same Availability Set or Virtual Machine Scale Set, whereas Standard SKU load balancers support standalone VMs.
2
Determine the required Load Balancer SKU.
A Standard SKU load balancer must be used because the backend VMs are standalone.
Using a Basic SKU load balancer would require recreating the virtual machines inside an Availability Set.
3
Determine the required Public IP SKU.
A Standard SKU public IP address must be created for the frontend.
Azure Load Balancer SKUs and Public IP SKUs must match; a Standard SKU load balancer cannot use a Basic SKU public IP.
