You have an Azure subscription that contains two virtual machines named VM1 and VM2. The network interface of each virtual machine is associated with a Basic SKU public IP address. You deploy a Standard SKU public load balancer named LB1. You need to add VM1 and VM2 to the backend pool of LB1. Which action should you perform first?
- Disassociate or upgrade the Basic SKU public IP addresses from the network interfaces of VM1 and VM2.Answer
- BConfigure the frontend IP configuration of LB1 to use a new Basic SKU public IP address.
- CAssociate a Network Security Group (NSG) with the subnets of VM1 and VM2.
- DCreate a new Basic SKU load balancer and configure LB1 to chain traffic to it.
Answer
Disassociate or upgrade the Basic SKU public IP addresses from the network interfaces of VM1 and VM2.
The correct answer is correct because a Standard SKU load balancer requires that any public IP addresses associated with virtual machines in its backend pool must also be of the Standard SKU. If the virtual machines have Basic SKU public IPs associated with their network interfaces, those IP addresses must be removed (disassociated) or upgraded to Standard SKU before the virtual machines can be successfully added to the backend pool of the Standard Load Balancer.
Step-by-Step Solution
Key Concept
Azure Standard Load Balancer backend pool members must have matching Standard SKU public IP configurations or no public IP configurations on their network interfaces.
