AZ-104 Certification Practice Question #227

Question

You have an Azure subscription that contains the resources in the following table.

You install the Web Server server role (IIS) on VM1 and VM2, and then add VM1 and VM2 to LB1.
LB1 is configured as shown in the LB1 exhibit. (Click the LB1 tab.)

Rule1 is configured as shown in the Rule1 exhibit. (Click the Rule1 tab.)

For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Hot Area:

Accepted Answer

1. **VM1 and VM2 must be in the same availability set:** Yes. Since LB1 is a Basic SKU load balancer, the backend pool virtual machines must belong to the same availability set or virtual machine scale set.
2. **If Probe1.htm is not present on VM1 and VM2, LB1 will not load balance TCP port 80 between VM1 and VM2:** Yes. Since the probe file is missing, the health probe fails for both VMs. For a Basic Load Balancer, when all instances are probed down, all TCP flows terminate/expire and no new flows are sent to the backend pool.
3. **If you delete Rule1, LB1 will load balance TCP port 80 between VM1 and VM2:** No. Without a load-balancing rule, the load balancer does not know how to map and forward inbound traffic from the frontend IP to the backend pool.
