AZ-104 Question #351: Real Exam Question with Answer & Explanation

LB1 is a Basic Internal Load Balancer on VNET1/Subnet12. VM1 and VM2 are both on VNET1 (specifically Subnet11 and Subnet12 respectively, or both within VNET1), making them eligible backend pool members for a Basic LB on the same virtual network - hence 'Yes' for VM1/VM2. VM3 and

Question

Hotspot Question You have an Azure subscription named Subscription1 that contains the virtual networks in the following table. Subscription1 contains the virtual machines in the following table. In Subscription1, you create a load balancer that has the following configurations: Name: LB1 SKU: Basic Type: Internal Subnet: Subnet12 Virtual network: VNET1 For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Answer:

Explanation

LB1 is a Basic Internal Load Balancer on VNET1/Subnet12. VM1 and VM2 are both on VNET1 (specifically Subnet11 and Subnet12 respectively, or both within VNET1), making them eligible backend pool members for a Basic LB on the same virtual network - hence 'Yes' for VM1/VM2. VM3 and VM4 are on VNET2, which is a different virtual network from LB1's VNET1; Basic SKU load balancers do NOT support cross-VNet backend pools (even with peering), so they cannot be balanced by LB1. VM5 and VM6 are on VNET3 and also likely run a different OS or configuration (e.g., Linux vs Windows) but more critically they are in a different VNet - again, Basic LB cannot include VMs from different virtual networks, ruling them out entirely.
