Subnet modes (auto, custom) in GCP - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a VPC network with automatic subnet creation.

GCP

resource "google_compute_network" "vpc_network" {
  name                    = "auto-subnet-network"
  auto_create_subnetworks = [1]
}

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

A"custom"

Btrue

C"auto"

Dfalse

💡 Hint

Common Mistakes

Using string values instead of boolean

Setting auto_create_subnetworks to false for auto mode

Setting auto_create_subnetworks to true enables automatic subnet creation in all regions.

2fill in blank

medium

Complete the code to create a custom subnet in a VPC network.

GCP

resource "google_compute_subnetwork" "custom_subnet" {
  name          = "custom-subnet"
  ip_cidr_range = "10.0.0.0/24"
  network       = google_compute_network.vpc_network.[1]
  region        = "us-central1"
}

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

💡 Hint

Common Mistakes

Using the network name instead of its ID

Using an undefined attribute

The network field expects the network's self_link to link the subnet to the VPC.

3fill in blank

hard

Fix the error in the network creation code to specify a custom subnet mode.

GCP

resource "google_compute_network" "custom_network" {
  name                    = "custom-network"
  auto_create_subnetworks = [1]
}

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

Atrue

B"auto"

C"custom"

Dfalse

💡 Hint

Common Mistakes

Setting auto_create_subnetworks to true for custom mode

Using string values instead of boolean

For custom subnet mode, auto_create_subnetworks must be set to false to disable automatic subnet creation.

4fill in blank

hard

Fill both blanks to create a custom subnet with the correct network reference and IP range.

GCP

resource "google_compute_subnetwork" "custom_subnet" {
  name          = "custom-subnet"
  ip_cidr_range = [1]
  network       = google_compute_network.custom_network.[2]
  region        = "europe-west1"
}

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

A"10.1.0.0/16"

Bid

Cname

D"192.168.1.0/24"

💡 Hint

Common Mistakes

Using network name instead of ID

Using invalid IP range format

The ip_cidr_range must be a valid CIDR block string, and network must reference the network's ID.

5fill in blank

hard

Fill all three blanks to define a VPC network in custom mode and create a subnet with a specific IP range and region.

GCP

resource "google_compute_network" "custom_network" {
  name                    = [1]
  auto_create_subnetworks = [2]
}

resource "google_compute_subnetwork" "custom_subnet" {
  name          = "custom-subnet"
  ip_cidr_range = [3]
  network       = google_compute_network.custom_network.id
  region        = "asia-east1"
}

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

A"custom-vpc-network"

Bfalse

C"10.2.0.0/20"

Dtrue

Attempts:

3 left

💡 Hint

Common Mistakes

Setting auto_create_subnetworks to true for custom mode

Using invalid IP range format

Using network name incorrectly

The network name is a string, auto_create_subnetworks is false for custom mode, and the subnet IP range is a valid CIDR string.
