[All AZ-720 Questions]

A company uses Azure virtual machines (VMs) in multiple regions. The VMs have the following configuration:

The backend pool of an internal Azure Load Balancer (ILB) named ILB1 contains VM1 and VM2. The ILB uses the Basic SKU and is in a resource group named RG2.
Virtual network peering has been configured between VNet1 and VNet2.
Users report that they are unable to connect to resources on VM1 and VM2 by using ILB1 from VM3.
You need to resolve the connectivity issues.
What should you do?

  • A. Move ILB1 to RG1.
  • B. Redeploy the ILB using the Standard SKU.
  • C. Redeploy VM1 and VM2 into availability zones.
  • D. Move VM1 and VM2 into RG3.

Selected Answer: B
B. Redeploy the ILB using the Standard SKU. The Basic SKU for the Azure Load Balancer does not support cross-VNet or peering scenarios. By deploying the ILB with a Standard SKU, it would support the required scenario where resources from one VNet need to connect to resources in another VNet. The other options do not address the root issue: A. Moving ILB1 to RG1 wouldn't help since the Load Balancer SKU is the issue, not the resource group it resides in. C. Redeploying VM1 and VM2 into availability zones would increase their resilience, but it wouldn't solve the issue of VM3 not being able to connect to VM1 and VM2 via the ILB. D. Moving VM1 and VM2 into RG3 would not resolve the issue for the same reason as option A - the problem lies with the Load Balancer SKU, not the resource group of the VMs.

Selected Answer: B
Since VM3 is in EUS2 and the backend VMs of the Basic iLB are in EUS, the iLB needs upgraded/redeployed as Standard SKU, since it doesn't support cross region communication.

The answer cannot be A since the resource group is a logical container. The correct answer is B since a Standard Load Balancer will allow connectivity between regions.
