Full question →easymultiple choiceObjective-mapped
An administrator is deploying a site-to-site VPN gateway in Azure. Which resource must be attached to the gateway so it can receive encrypted connections from the on-premises VPN device?
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
A public IP address resource.
The VPN gateway needs a public-facing IP address so the on-premises VPN device can establish the encrypted tunnel.
B
Distractor review
A private endpoint.
Private endpoints are for private access to PaaS services, not for VPN gateway tunnel termination.
C
Distractor review
A service endpoint.
Service endpoints are for subnet access to Azure services and do not provide a VPN gateway address.
D
Distractor review
A network security group.
NSGs filter traffic, but they do not supply the public-facing endpoint needed for VPN connectivity.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

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?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: A public IP address resource. — A site-to-site VPN gateway must have a public IP address resource attached so the on-premises VPN device has a public endpoint to connect to. The encrypted tunnel is established to that public-facing address. Without a public IP, the gateway cannot be reached from the external network, so deployment validation will fail or the connection cannot be formed. Why others are wrong: Private endpoints and service endpoints are unrelated to VPN tunnel termination and are used for PaaS service access. An NSG can restrict traffic to or from resources, but it does not create the gateway’s externally reachable address. The key requirement here is a public endpoint for the VPN gateway, not a firewall rule or private service attachment.
