- A
You can associate a route table with a subnet.
Correct because Azure attaches user-defined routes to subnets, not directly to individual virtual machines.
- B
A user-defined route can send traffic to a virtual appliance as the next hop.
Correct because UDRs support a virtual appliance next hop, which is useful for firewalls and inspection devices.
- C
Route tables can be associated directly to a single virtual machine without using its subnet.
Why wrong: False because route tables are applied at the subnet level. The VM inherits the subnet's routing behavior.
- D
A user-defined route automatically overrides a network security group deny rule.
Why wrong: False because routing and security rules are different controls. A route does not bypass an NSG deny.
- E
System routes are never used when a route table exists.
Why wrong: False because Azure still uses system routes where no more specific user-defined route applies.
Quick Answer
The correct answer is that a user-defined route can send traffic to a virtual appliance as the next hop. This is correct because Azure route tables are associated at the subnet level, not directly to a virtual machine, and user-defined routes (UDRs) within that table override Azure’s system default routes for traffic leaving the subnet. The next hop in a UDR can be set to a virtual appliance, such as a firewall or network virtual appliance (NVA), allowing you to force-tunnel traffic for inspection or filtering. On the AZ-104 exam, this concept tests your understanding of how to control network traffic flow and is often paired with a scenario where you must choose the correct next hop type—common traps include confusing the next hop “Virtual appliance” option with “Internet” or “None.” A helpful memory tip is to think of UDRs as “detour signs” for subnet traffic: they can point to a virtual appliance for inspection, but the route table itself must be in the same region as the subnet.
AZ-104 Implement and Manage Virtual Networking Practice Question
This AZ-104 practice question tests your understanding of implement and manage virtual networking. 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.
Which two statements about Azure route tables and user-defined routes are correct? Select two.
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
You can associate a route table with a subnet.
Option A is correct because route tables in Azure are associated at the subnet level, not directly to a virtual machine. This association allows the route table's user-defined routes (UDRs) to override system default routes for traffic leaving that subnet. The subnet must be in the same region as the route table, and a single route table can be associated with multiple subnets.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the scope of route table association (subnet vs. VM) and assume UDRs can override NSG rules, when in fact routing and firewall filtering are separate layers in Azure's networking stack.
Detailed technical explanation
How to think about this question
Under the hood, Azure uses a system route table per subnet with default routes for virtual network, VPN gateway, and internet traffic. When you associate a custom route table, Azure merges the system routes with your UDRs, with UDRs taking precedence for matching prefixes. The next hop type 'Virtual appliance' requires an IP address of a VM or Azure Firewall that performs IP forwarding, and traffic is routed based on the destination prefix in the UDR, not the NSG rules. In a hub-and-spoke topology, UDRs are critical to force-tunnel traffic through a firewall for inspection.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
