Zorluk: ZorConfigure Azure Load Balancer

You have an Azure subscription that contains a virtual network named VNet1. VNet1 contains two virtual machines named VM1 and VM2. VM1 and VM2 are deployed as standalone virtual machines. VM1 has a public IP address named IP1 assigned directly to its network interface. IP1 is configured with the Basic SKU. VM2 does not have a public IP address. You provision a new public IP address named IP2 configured with the Standard SKU. You plan to create a public load balancer named LB1, use IP2 as the frontend IP configuration, and distribute inbound traffic to VM1 and VM2. You need to configure the load balancer and the virtual machines to support this configuration. Which two actions should you perform?

  1. Create LB1 as a Standard load balancer.Cevap
  2. Disassociate the public IP address IP1 from the network interface of VM1.Cevap
  3. C
    Create LB1 as a Basic load balancer.
  4. D
    Associate the public IP address IP1 as the frontend IP configuration for LB1.

Cevap

Create LB1 as a Standard load balancer and disassociate the public IP address IP1 from the network interface of VM1.
To deploy a public load balancer with a Standard SKU public IP frontend that distributes traffic to standalone virtual machines, you must create a Standard load balancer. Furthermore, because Standard load balancers require all instance-level public IP addresses in the backend pool to use the Standard SKU, the Basic SKU public IP address (IP1) currently assigned to the network interface of VM1 must be disassociated.

Adım Adım Çözüm

1
Determine the required SKU for the load balancer based on the frontend IP address.
Since the frontend public IP address (IP2) is a Standard SKU, the load balancer (LB1) must also be a Standard SKU load balancer.
Standard SKU public IP addresses can only be associated with Standard SKU load balancers.
2
Determine the required SKU for the load balancer based on the backend pool configuration.
Since VM1 and VM2 are standalone virtual machines, a Standard SKU load balancer is required.
Basic SKU load balancers only support backend instances deployed within a single Availability Set or Virtual Machine Scale Set.
3
Verify and resolve SKU compatibility of public IP addresses on the backend virtual machines.
VM1 has a Basic SKU public IP (IP1) directly assigned. This IP1 must be disassociated from VM1.
Standard SKU load balancers require all public IPs associated with the backend instances to be Standard SKU. A Basic SKU public IP on a backend VM NIC is incompatible.
