Question 14

vNet

Answer 14

logically isolated section of Azure Network where launch Azure resources. Choose a range of IPs using CIDR range. In vNet can have a public subnet (which can connect to internet) and private (e.g. with db)
CIDR range - smaller the number after /, the wider the range of addresses

Question 15

subnet

Answer 15

logical partition of IP network into smaller network segments. Breaking up IP range for VNet into smaller networks. (will have smaller CIDR range than vnet, representing their portion)

Question 16
