Question 1hardmultiple choice
Full question →hardmultiple choiceObjective-mapped
Your company deploys a network virtual appliance (NVA) in a hub subnet. All outbound internet traffic from Subnet-App in a spoke VNet must pass through the NVA for inspection. What should you configure on Subnet-App?
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
Distractor review
A private DNS zone
DNS affects name resolution, not forced routing through the appliance.
B
Best answer
A user-defined route with a next hop of Virtual Appliance
This explicitly steers traffic from the subnet to the NVA for inspection.
C
Distractor review
A service endpoint for Microsoft.Storage
Service endpoints optimize access to Azure services, not all internet-bound traffic.
D
Distractor review
A NAT gateway on the NVA subnet only
This does not by itself redirect the spoke subnet traffic through the NVA.
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: A user-defined route with a next hop of Virtual Appliance — A user-defined route can send traffic from the spoke subnet to the NVA by using the Virtual Appliance next-hop type and the NVA's private IP. DNS zones and service endpoints do not redirect general outbound traffic, and a NAT gateway on the NVA subnet would not force traffic from Subnet-App through the appliance.
