An administrator is designing a public Azure Load Balancer named LB1 to distribute internet traffic to two virtual machines named VM1 and VM2. VM1 and VM2 are standalone virtual machines deployed in the same virtual network and are not associated with any availability set or virtual machine scale set. The administrator creates a Standard SKU public IP address named PIP1 to serve as the frontend IP configuration for the load balancer. Which configuration must the administrator choose for LB1 to successfully implement this solution?
- Select the Standard SKU for LB1, and add VM1 and VM2 directly to the backend pool.Answer
- BSelect the Basic SKU for LB1, and add VM1 and VM2 directly to the backend pool.
- CSelect the Basic SKU for LB1, change the SKU of PIP1 to Basic, and add VM1 and VM2 directly to the backend pool.
- DSelect the Standard SKU for LB1, and associate VM1 and VM2 with a new availability set before adding them to the backend pool.
Answer
Select the Standard SKU for LB1, and add VM1 and VM2 directly to the backend pool.
The correct configuration is to select the Standard SKU for the load balancer and add the standalone virtual machines directly to the backend pool. A Standard SKU load balancer requires a Standard SKU public IP address and supports any virtual machines in a single virtual network as backend pool members, including standalone VMs.
