DRAG DROP
You have a solution deployed into a virtual network in Azure named fabVNet. The fabVNet virtual network has
three subnets named Apps, Web, and DB that are configured as shown in the exhibit. (Click the Exhibits
button.)
You want to deploy two new VMs to the DB subnet.
You need to modify the virtual network to expand the size of the DB subnet to allow more IP addresses.
Which three steps should you perform in sequence? To answer, move the appropriate actions from the list of
actions to the answer area and arrange them in the correct order.

Answer: 
Why should you empty and reconfigure the web-subnet to be larger?
There is no reason I can see that you need to do that either. The DB subnet has to be emptied or deleted for reconfiguring. But then you can just use the network 10.0.0.80/28 for DB and leave Web on 10.0.0.64/29.
If the subnet of *Web* needed to be made bigger there would be a case for changing both DB and Web.
Anyway, the provided answer is the only one that makes any sense using 3 options so I assume it is correct.
wrong Answer…its should be
1. Empty and Delete the DB Subnet
2. Create the DB Subnet to be Larger
3. Recreate the Virtual Network as Now Required
Nope, given answer is correct. go lab it out and see.
