Full question →mediummultiple choiceObjective-mapped
A security team requires all outbound internet traffic from a workload subnet to pass through an NVA at 10.1.4.4. The subnet is already associated with an NSG that allows the traffic. Which UDR should the administrator add to the route table for that subnet?
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
Destination 10.1.4.4/32 with next hop type Internet.
This route does not send default outbound traffic through the appliance. It points to the wrong next hop type.
B
Best answer
Destination 0.0.0.0/0 with next hop type Virtual appliance and next hop IP 10.1.4.4.
To force all internet-bound traffic through a network virtual appliance, the route table needs a default route that matches 0.0.0.0/0 and sends traffic to the appliance's private IP. The next hop type must be Virtual appliance, and the next hop IP should be 10.1.4.4. This overrides Azure's default system route for internet traffic from that subnet, while still allowing NSG rules to control whether the traffic is permitted.
C
Distractor review
Destination 0.0.0.0/0 with next hop type Virtual network gateway.
A virtual network gateway is used for VPN or ExpressRoute paths, not for sending traffic to an NVA inside the VNet.
D
Distractor review
Destination 10.1.4.0/24 with next hop type None.
A None next hop would blackhole matching traffic instead of forwarding it through the security appliance.
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

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: Destination 0.0.0.0/0 with next hop type Virtual appliance and next hop IP 10.1.4.4. — A UDR can override Azure's default system route when traffic must follow a specific path. For outbound internet access inspection, the common pattern is a default route for 0.0.0.0/0 pointing to the NVA's private IP using the Virtual appliance next hop type. That sends all unmatched outbound traffic to 10.1.4.4 for inspection or logging before it exits. The NSG still applies separately, so routing and security remain distinct controls. Why others are wrong: A host route to the appliance itself does not steer general outbound traffic, and the Internet next hop would bypass the NVA. Virtual network gateway is for hybrid connectivity, not an appliance in the subnet. A None next hop drops traffic instead of forwarding it. Only the default route to the appliance matches the stated requirement.
