A. 1 This is because a single Azure Bastion host can serve all the VNets that are peered with the hub VNet where the Bastion service is deployed.

Given what I know: - I know 1 Bastion for 1 VNet - Peered VNets can have 1 Bastion. - There is only 2 VNets in the description are peered that is VNet1 and VNet2. So 1 Bastion for the peered (VFNet1 and Vnet2) and the rest gets 1 Bastion each So it is 3 Bastion altogether. So where the answer 2 coming from? is it possible that only 2 the subnets that has Windows machines get Bastion? Then I read Linux machine also supports Bastion. Help - thx

I think I got it ... This all about how this peering is configured ... - Hub Vnet is peered with VNet1 and VNet2 - so that means 1 Bastion would work for all -And then VNet3 and VNet4 are also peered - so that means 1 Bastion for them So 2 would be the answer ..- Final Answer

oh nevermind, the question should be asking: How many "dedicated Azure Bastion subnets" are required, then it makes more sense to me that the answer is 2.

aren't people who are saying 2 is the answer forgetting that the bastion requires its own subnet? Answer is 3.

yes but if the subnets are peered than you can go with 1 for the peered subnets. So this answer 2 is also throwing me off as well

B is the answer. https://learn.microsoft.com/en-us/azure/bastion/vnet-peering Azure Bastion and VNet peering can be used together. When VNet peering is configured, you don't have to deploy Azure Bastion in each peered VNet. This means if you have an Azure Bastion host configured in one virtual network (VNet), it can be used to connect to VMs deployed in a peered VNet without deploying an additional bastion host.

So i thought it was 3 Bastions but when you actually look a bit closer you will see that the Vnet column on the left hand side shows the VNET the VM is in and the column on right is the Peered VNET so : VNET 1-2 ARE PEERED VNET 3-4 ARE PEERED ...THEREFORE KIDS WE NEED ONLY TWO BASTION : B

Yes, i don't see either where it shows VNet 3 and VNet 4 are peered. I don't get it how the answer is 2. I know one VNet requires 1 Bastion and peered VNets can have 1 Bastion. So there is only 2 VNets are peered that is VNet1 and VNet 2. so how the answer is 2? pls explain - thx I know you can have 1 Bstion
