Free Microsoft Azure AZ-700 Actual Exam Questions - Question 8 Discussion
You plan to deploy an Azure Virtual Network NAT gateway named Gateway 1. The solution must
meet the following requirements:
• VM1 will access the internet by using its public IP address.
• VM2 will access the internet by using its public IP address.
• Administrative effort must be minimized.
You need to ensure that you can deploy Gateway1 to Vnet1.
What is the minimal number of subnets that Vnet1 must have?
A/B? You need at least one subnet for the NAT gateway and one for both VMs if they can share a subnet. Separate subnets for each VM aren’t strictly needed unless isolation is required.
Maybe B. One subnet for the NAT gateway, one for VM1, and one for VM2 to keep their public IPs separate and minimize admin effort. That fits the requirement better than just two subnets.
A vs B? Since NAT gateway needs its own subnet, that’s one right there. Both VMs can be in the same subnet if they share a public IP or use the NAT gateway for outbound. The question says VM1 and VM2 need their own public IPs for internet access, which usually means they must be in separate subnets or have individual IPs attached. But you can assign public IPs directly to VMs in the same subnet, so maybe only two subnets are enough: one for NAT gateway, one for both VMs. So I’d pick A here.
NAT gateways require their own dedicated subnet, but VMs can share subnets. So one subnet for the NAT gateway plus one for both VMs could work. Does that mean only 2 subnets are really needed?
D imo, you need a dedicated subnet for the NAT gateway, plus separate ones for VM1 and VM2. But since it mentions minimizing admin effort, you might combine some roles—but NAT gateways require their own subnet. Also, if Vnet1 already has a gateway or other resources, that might add to the subnet count. So 5 subnets (D) covers all bases without breaking Azure rules, especially if you consider management and any additional roles.
This question feels a bit confusing without the image, but I’m guessing it’s about making sure the NAT gateway can cover both VMs in Vnet1 while minimizing subnets. You usually need a dedicated subnet for the NAT gateway itself, plus enough subnets for the VMs. Since they want minimal administrative effort, maybe 2 subnets is enough-one for VMs and one for NAT? So maybe A makes the most sense here. Anyone else think the same or have a different take?
