A company wants encrypted connectivity between its on-premises network and an Azure VNet. The organization has one edge VPN device at headquarters, and the Azure design must support a classic site-to-site tunnel rather than individual user VPN connections. Which three prerequisites are required? Select three.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Deploy a virtual network gateway in a dedicated GatewaySubnet.
Azure VPN gateways must be deployed into the special GatewaySubnet within the VNet.
B
Best answer
Assign a public IP address to the Azure VPN gateway.
The gateway needs a public-facing endpoint so the on-premises device can establish the tunnel.
C
Best answer
Configure the on-premises VPN device with a public IP and supported IKE/IPsec settings.
The on-premises device must be reachable and must use compatible tunnel parameters.
D
Distractor review
Create a private endpoint for the headquarters network.
Private endpoints are for PaaS service access, not for hybrid VPN tunnel establishment.
E
Distractor review
Enable Microsoft peering on the virtual network gateway.
Microsoft peering is associated with ExpressRoute concepts, not standard site-to-site VPN gateways.
Common exam trap
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.
Technical deep dive
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.

Question 1
A route table contains these entries: 10.0.0.0/8 with next hop Virtual appliance, and 10.1.1.0/24 with next hop Virtual network gateway. Which next hop will Azure use for traffic to 10.1.1.5?
Question 2
You are deploying a stateless web application on Azure virtual machines. The solution must automatically add and remove instances based on CPU demand and allow all instances to be managed as one logical group. Which Azure compute feature should you deploy?
Question 3
You are deploying a Windows Server VM for an internal app. The VM must support Secure Boot and vTPM later, its OS disk must survive host moves, and the team wants the lowest-cost managed disk tier that still behaves like a normal writable OS disk. Which two choices should you make? Select two.
Question 4
You need to deploy several identical virtual machines and ensure that the failure of a single Azure host does not affect all of them. Which feature should you use?
Question 5
You need to connect VNet-Hub and VNet-Spoke so that resources in both virtual networks can communicate privately over the Microsoft backbone. Both virtual networks are in the same region. What should you configure?
Question 6
You need to create a storage account that provides the lowest-cost redundant storage for non-critical data and only needs protection against local disk or server failure within a single datacenter. Which redundancy option should you choose?
FAQ
Questions learners often ask
What does this AZ-104 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: Deploy a virtual network gateway in a dedicated GatewaySubnet. — A site-to-site VPN requires an Azure VPN gateway in the GatewaySubnet, because that is where the gateway service is deployed. The gateway also needs a public IP address so the on-premises device can connect to it over the internet. Finally, the on-premises VPN appliance must have a compatible public endpoint and use matching IKE/IPsec settings. All three pieces are necessary before the tunnel can come up. Why others are wrong: Private endpoints are unrelated to VPN tunnel creation and only solve private access to supported services. Microsoft peering is not a VPN requirement and belongs to a different connectivity model. Those distractors are common because they sound like network connectivity features, but they do not create an encrypted site-to-site tunnel.
