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.
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 VPNgateway, 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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
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.
✗
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.
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 VPNgateway. 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.
