VNet creation and address space in Azure - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the address space for the virtual network.

Azure

az network vnet create --name MyVNet --resource-group MyResourceGroup --address-prefixes [1]

Drag options to blanks, or click blank then click option'

A"255.255.255.0"

B"192.168.1.0/24"

C"172.16.0.0/12"

D"10.0.0.0/16"

💡 Hint

Common Mistakes

Using a subnet mask instead of CIDR notation.

Choosing an address space too small for the network.

The address space must be a valid CIDR block like "10.0.0.0/16". Option D is a subnet mask, not an address space.

2fill in blank

medium

Complete the code to create a subnet within the VNet with the correct address prefix.

Azure

az network vnet subnet create --resource-group MyResourceGroup --vnet-name MyVNet --name MySubnet --address-prefix [1]

Drag options to blanks, or click blank then click option'

A"10.0.1.0/24"

B"192.168.1.0/24"

C"10.0.0.0/16"

D"172.16.0.0/12"

💡 Hint

Common Mistakes

Using an address prefix outside the VNet's range.

Using the same prefix as the VNet for the subnet.

The subnet address prefix must be a subset of the VNet's address space. "10.0.1.0/24" fits inside "10.0.0.0/16".

hard

Fix the error in the VNet creation command by choosing the correct parameter for address space.

Azure

az network vnet create --name MyVNet --resource-group MyResourceGroup --[1] "10.0.0.0/16"

Drag options to blanks, or click blank then click option'

Caddress-space

Dsubnet-prefix

💡 Hint

Common Mistakes

Using a singular form that does not exist.

Confusing subnet prefix with VNet address space.

The correct parameter to specify one or more address spaces is --address-prefixes.

4fill in blank

hard

Fill both blanks to create a VNet with two address spaces.

Azure

az network vnet create --name MyVNet --resource-group MyResourceGroup --address-prefixes [1] [2]

Drag options to blanks, or click blank then click option'

A"10.0.0.0/16"

B"192.168.0.0/16"

C"10.1.0.0/16"

D"172.16.0.0/12"

💡 Hint

Common Mistakes

Using overlapping address spaces.

Using invalid CIDR notation.

You can specify multiple address spaces separated by spaces. Here, "10.0.0.0/16" and "10.1.0.0/16" are valid and non-overlapping.

5fill in blank

hard

Fill all three blanks to create a subnet with a specific name and address prefix inside a VNet.

Azure

az network vnet subnet create --resource-group MyResourceGroup --vnet-name [1] --name [2] --address-prefix [3]

Drag options to blanks, or click blank then click option'

AMyVNet

BMySubnet

C"10.0.2.0/24"

DMyResourceGroup

💡 Hint

Common Mistakes

Mixing resource group name with VNet name.

Using invalid address prefix format.

The VNet name is "MyVNet", the subnet name is "MySubnet", and the subnet address prefix must be a valid CIDR block inside the VNet.
