AZ-104 Implement and Manage Virtual Networking Practice Question
This AZ-104 practice question tests your understanding of implement and manage virtual networking. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Traffic from VM-App01 is taking an unexpected path to the internet through a network virtual appliance. You need to determine which routes are actually applied to the VM network interface. Which Azure feature should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Effective routes for the network interface
Effective routes for a network interface show the actual routes applied to the VM's NIC after combining all route sources (system routes, BGP, and user-defined routes). This allows you to verify whether traffic is being forced through the NVA or taking an unexpected path, by inspecting the next hop type and IP address for the 0.0.0.0/0 route.
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.
✓
Effective routes for the network interface
Why this is correct
Effective routes display the route entries that are actively applied to the NIC.

Read the scenario before looking for a memorised answer.
✗
NSG flow logs
Why it's wrong here
NSG flow logs show allow or deny outcomes for traffic, not the route table applied to the NIC.
✗
Azure Policy compliance
Why it's wrong here
Policy compliance does not show active routing entries.
✗
The subscription activity log
Why it's wrong here
The activity log records control-plane changes and not the effective route list.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'effective routes' with 'NSG flow logs' because both involve network troubleshooting, but effective routes solve routing-path issues while flow logs solve firewall/security-rule issues.
Trap categories for this question
Command / output trap
NSG flow logs show allow or deny outcomes for traffic, not the route table applied to the NIC.
Detailed technical explanation
How to think about this question
Effective routes are computed by Azure's virtual network stack from system routes (Azure default, VNet peering, VPN/BGP), user-defined routes (UDRs), and service endpoints. The effective route table for a NIC can be retrieved via Azure Portal, PowerShell (Get-AzEffectiveRouteTable), or CLI (az network nic show-effective-route-table). A common subtlety is that effective routes do not include routes from Azure Firewall or NVA policies themselves—only the UDRs that direct traffic to them.
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.
