HOTSPOT - You have an Azure subscription that contains a virtual machine scale set named VMSS1 and a public standard Azure load balancer named LB1. VMSS1 contains eight virtual machines that have private IP addresses only. VMSS1 is configured as a backend pool of LB1. LB1 has two frontend IP addresses and one outbound rule that provides internet connectivity to VMSS1. What is the maximum number of ports available to the virtual machines in VMSS1, and what should you change to increase the maximum number of SNAT ports available to VMSS1? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.

Answer: See figure below
Explanation
Maximum Number of Ports: The maximum number of ports available is determined by the number of frontend IP addresses and outbound rules. Each frontend IP address in a Standard Load Balancer provides 64,000 SNAT ports. Correct Selection: 128K Since LB1 has two frontend IP addresses and each provides 64,000 SNAT ports, the total is 128K ports. Increase the Number of SNAT Ports: To increase the number of SNAT ports available, you need to add more frontend IP addresses because each frontend IP provides an additional 64,000 ports. Correct Selection: Frontend IP addresses for LB1 Adding more frontend IP addresses to LB1 will increase the total SNAT port pool.
