Question 742 of 1,170
Does UDR Override BGP Propagated Routes in Azure?
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.
A spoke subnet has a user-defined route for 10.60.0.0/16 that sends traffic to a virtual appliance at 10.1.0.4. The same subnet also learns a propagated route for 10.60.0.0/16 from a VPN gateway. A VM in the subnet sends traffic to 10.60.7.25. Which next hop will Azure use?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The virtual appliance at 10.1.0.4
Azure uses the most specific route match, and user-defined routes (UDRs) take precedence over propagated routes (BGP) for the same prefix. Since the UDR for 10.60.0.0/16 with next hop 10.1.0.4 is more specific than the propagated route from the VPN gateway, traffic to 10.60.7.25 is forwarded to the virtual appliance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

The virtual appliance at 10.1.0.4
Why this is correct
A user-defined route with the same prefix takes precedence over a propagated route for that destination.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
The VPN gateway
Why it's wrong here
A propagated route exists, but it loses to the same-prefix user-defined route in this case.
- ✗
The Internet
Why it's wrong here
Neither the destination nor the routing configuration sends this private prefix to the Internet.
When this WOULD be correct
If the question stated that the subnet had no UDR and only a default route (0.0.0.0/0) pointing to the internet, and the destination was not covered by any other route, then the next hop would be the internet.
- ✗
No next hop is available
Why it's wrong here
Azure still has a valid route; it simply selects the user-defined route over the propagated one.
When this WOULD be correct
If the question stated that the UDR was removed or had a next hop type of 'None', and no other route (including propagated) matched the destination, then Azure would drop the traffic and no next hop would be available.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓The virtual appliance at 10.1.0.4Correct answer▾
Why this is correct
A user-defined route with the same prefix takes precedence over a propagated route for that destination.
✗The VPN gatewayWrong answer — click to see why▾
Why this is wrong here
User-defined routes (UDRs) take precedence over propagated routes from VPN gateways for the same prefix. Since the subnet has a UDR for 10.60.0.0/16 pointing to the virtual appliance, Azure uses that next hop instead of the VPN gateway.
★ When this WOULD be the correct answer
If the subnet did not have a user-defined route for 10.60.0.0/16, and only learned the route via BGP from the VPN gateway, then the VPN gateway would be the next hop for traffic to 10.60.7.25.
Why candidates choose this
Candidates may mistakenly think that propagated routes from VPN gateways override user-defined routes, or they may overlook the precedence order where UDRs are preferred over BGP routes for the same prefix.
✗The InternetWrong answer — click to see why▾
Why this is wrong here
Azure uses the most specific route match (longest prefix) and prefers user-defined routes over propagated BGP routes. Since the UDR for 10.60.0.0/16 with next hop 10.1.0.4 is more specific than the VPN gateway route for the same prefix, traffic goes to the virtual appliance, not the internet.
★ When this WOULD be the correct answer
If the question stated that the subnet had no UDR and only a default route (0.0.0.0/0) pointing to the internet, and the destination was not covered by any other route, then the next hop would be the internet.
Why candidates choose this
Candidates may mistakenly think that if a route is learned from a VPN gateway, the traffic must go through the internet, or they confuse the default route (0.0.0.0/0) with a specific prefix route.
✗No next hop is availableWrong answer — click to see why▾
Why this is wrong here
Azure uses the most specific route match, and the user-defined route (UDR) for 10.60.0.0/16 with next hop virtual appliance is more specific than the propagated route from VPN gateway, so a next hop is available.
★ When this WOULD be the correct answer
If the question stated that the UDR was removed or had a next hop type of 'None', and no other route (including propagated) matched the destination, then Azure would drop the traffic and no next hop would be available.
Why candidates choose this
Candidates might think that because the VPN gateway also advertises the same prefix, the UDR might be overridden or that the route propagation could cause a conflict leading to no valid next hop, but Azure's route selection is deterministic.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume BGP-propagated routes always take precedence over UDRs, but Azure gives UDRs higher priority for the same prefix, and the longest prefix match rule is applied first.
Detailed technical explanation
How to think about this question
Azure route selection follows the order: longest prefix match, then lowest administrative distance (UDRs have AD 0, BGP routes have AD 20), and finally system routes. The UDR for 10.60.0.0/16 is a static route that overrides the BGP-learned route for the same prefix, ensuring traffic is inspected or processed by the virtual appliance (NVA) before reaching the VPN gateway. In a hub-and-spoke topology, this design allows centralized inspection of inter-spoke traffic via the NVA.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
