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 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?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Virtual network gateway, because the /24 route is more specific than the /8 route.
Azure uses the most specific route prefix (longest prefix match) to determine the next hop for traffic. For destination 10.1.1.5, the route 10.1.1.0/24 (prefix length 24) is more specific than 10.0.0.0/8 (prefix length 8), so the next hop Virtual network gateway is selected, regardless of the order in which routes were created.
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.
✗
Virtual appliance, because the broader 10.0.0.0/8 route was created first.
Why it's wrong here
Azure does not choose the first created route when a more specific route exists.
✓
Virtual network gateway, because the /24 route is more specific than the /8 route.
Why this is correct
The most specific matching prefix wins, so the /24 route takes precedence for 10.1.1.5.
Related concept
Read the scenario before looking for a memorised answer.
✗
Internet, because Azure always prefers the default system route for public addresses.
Why it's wrong here
A matching user-defined route overrides the default system route for the destination.
✗
None, because Azure ignores overlapping route entries in the same table.
Why it's wrong here
Azure supports multiple routes, and it selects the best match rather than ignoring them all.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates mistakenly believe route creation order or the 'broader' route being created first determines priority, but Azure always uses the most specific prefix match, not the order of route entries.
Detailed technical explanation
How to think about this question
Azure route tables use the longest prefix match algorithm, identical to how IP forwarding works in routers. The prefix length (e.g., /24 vs /8) determines specificity; a /24 route is more specific than a /8 route for any address within the /24 range. This behavior is defined by RFC 4632 and is fundamental to how Azure selects the next hop for traffic, overriding any system routes or less specific custom routes.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.

What is the correct answer to this question?
The correct answer is: Virtual network gateway, because the /24 route is more specific than the /8 route. — Azure uses the most specific route prefix (longest prefix match) to determine the next hop for traffic. For destination 10.1.1.5, the route 10.1.1.0/24 (prefix length 24) is more specific than 10.0.0.0/8 (prefix length 8), so the next hop Virtual network gateway is selected, regardless of the order in which routes were created.
