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 new spoke virtual network will peer with an existing hub that uses 10.10.0.0/16 and an on-premises network that uses 10.20.0.0/16. Which two address spaces could you assign to the new spoke without overlapping those ranges? Select two.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
10.11.0.0/16
Option A (10.11.0.0/16) is correct because it is a distinct subnet within the private 10.0.0.0/8 range that does not overlap with the hub's 10.10.0.0/16 or the on-premises 10.20.0.0/16. Azure virtual network peering requires non-overlapping address spaces to enable direct routing between resources without conflict.
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.
✓
10.11.0.0/16
Why this is correct
Correct because this range does not overlap with the existing hub or on-premises address spaces.

✗
10.10.128.0/17
Why it's wrong here
False because this range falls inside the hub's 10.10.0.0/16 address space and would overlap.
✓
192.168.50.0/24
Why this is correct
Correct because this private range is separate from both existing 10.10.0.0/16 and 10.20.0.0/16 spaces.
Related concept
Read the scenario before looking for a memorised answer.
✗
10.20.1.0/24
Why it's wrong here
False because this range is contained within the on-premises 10.20.0.0/16 network and overlaps.
✗
10.10.1.0/24
Why it's wrong here
False because this range overlaps the hub network, which already uses the 10.10.0.0/16 space.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume any /16 or /24 within the 10.0.0.0/8 range is safe, but they must check for subnet overlap with both the hub and on-premises networks, not just the hub's primary range.
Detailed technical explanation
How to think about this question
Azure virtual network peering uses the hub-spoke topology where each spoke must have a unique address space to avoid routing conflicts. The hub typically acts as a central connectivity point, often with a VPNgateway or Azure Firewall, and overlapping address spaces would cause asymmetric routing or failure to establish the peering connection. In practice, you must plan address spaces carefully, especially when integrating with on-premises networks via ExpressRoute or S2S VPN, as overlapping ranges can break connectivity entirely.

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.
