How to Create a VPC Network with a Subnet in Google Cloud

This GCDL practice question tests your understanding of why cloud technology is transforming business. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Drag and drop the steps to create a new Virtual Private Cloud (VPC) network with a subnet in Google Cloud into the correct order.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Navigate to VPC networks page, then click 'Create VPC Network', then enter a name for the VPC, then configure the subnet settings, then click 'Create'.

The correct order starts with navigating to the VPC networks page, then creating a new VPC, naming it, configuring the subnet, and finally creating it.

Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Navigate to VPC networks page, then click 'Create VPC Network', then enter a name for the VPC, then configure the subnet settings, then click 'Create'.

    Why this is correct

    This is correct because in the Google Cloud Console, you must first navigate to the VPC networks page, then initiate the creation process by clicking 'Create VPC Network', then enter a name, configure subnets, and finally create the network.

    Related concept

    CIDR notation defines the prefix length.

  • Navigate to VPC networks page, then click 'Create VPC Network', then configure the subnet settings, then enter a name for the VPC, then click 'Create'.

    Why it's wrong here

    This is incorrect because in the Google Cloud Console, you must enter the VPC name before configuring subnet settings; the name field appears before the subnet configuration section.

  • Click 'Create VPC Network', then navigate to VPC networks page, then enter a name, then configure subnet, then click 'Create'.

    Why it's wrong here

    This is incorrect because you cannot click 'Create VPC Network' before navigating to the VPC networks page; the button is only available on that page.

  • Navigate to VPC networks page, then enter a name for the VPC, then click 'Create VPC Network', then configure the subnet, then click 'Create'.

    Why it's wrong here

    This is incorrect because you cannot enter a name before clicking 'Create VPC Network'; the name field appears only after you start the creation flow.

Common exam traps

Common exam trap: usable hosts are not the same as total addresses

Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.

Detailed technical explanation

How to think about this question

Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.

KKey Concepts to Remember

  • CIDR notation defines the prefix length.
  • Block size helps identify subnet boundaries.
  • Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
  • The required host count determines the smallest suitable subnet.

TExam Day Tips

  • Write the block size before choosing the subnet.
  • Check whether the question asks for hosts, subnets or a specific address range.
  • Do not confuse /24, /25, /26 and /27 host counts.

Key takeaway

Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

Real-world example

How this comes up in practice

A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.

Visual reference

192.168.1.0 /24 256 addresses (254 usable) 192.168.1.0 /25 Subnet A 128 addr (126 usable) 192.168.1.128 /25 Subnet B 128 addr (126 usable) Borrowing 1 bit from host portion creates 2 subnets (/25)

What to study next

Got this wrong? Here's your next step.

Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related GCDL subnetting questions on CIDR, address ranges, and subnet selection.
