- A
Enable BGP on the Azure VPN gateway and advertise routes to the on-premises network.
Why wrong: BGP is for route exchange but does not force traffic through the firewall.
- B
Configure Azure Firewall with a route to the VPN gateway for on-premises traffic.
The firewall needs a route to forward traffic to the VPN gateway.
- C
In the hub virtual network, set 'Use remote gateways' on the peering connection to the spoke.
Why wrong: This is used when the hub wants to use the spoke's gateway, which is not the case.
- D
Configure user-defined routes (UDRs) in each spoke subnet with 0.0.0.0/0 next hop to Azure Firewall, and include on-premises prefixes with next hop to Azure Firewall.
UDRs direct traffic to the firewall for inspection.
- E
In the spoke virtual network, set 'Gateway transit' on the peering connection to the hub.
This allows the spoke to use the hub's VPN gateway, and traffic must go through the firewall due to UDRs.
Quick Answer
The answer is to configure User-Defined Routes (UDRs) in the spoke, enable Gateway Transit on the hub’s peering, and set the Azure Firewall as the next hop for on-premises traffic. This forces all spoke-to-on-premises traffic through the firewall by overriding default system routes with a UDR pointing to the firewall’s private IP, while Gateway Transit allows the spoke to use the hub’s VPN gateway without its own gateway. On the AZ-500 exam, this scenario tests your understanding of forced tunneling in a hub-and-spoke topology, often appearing as a multi-select question where the trap is confusing VNet peering (which doesn’t inspect traffic) with route-based inspection. Remember the mnemonic “UDR, Transit, Firewall” — the spoke needs the route, the hub needs the transit permission, and the firewall must be the next hop. Propagating gateway routes is unnecessary here because the UDR explicitly directs traffic, and BGP alone won’t enforce inspection.
AZ-500 Secure networking Practice Question
This AZ-500 practice question tests your understanding of secure networking. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Your company has a single Azure subscription with a hub-and-spoke network topology. The hub virtual network contains Azure Firewall and a VPN gateway for hybrid connectivity. You need to ensure that all traffic from the spoke virtual networks to on-premises is inspected by the Azure Firewall. Which THREE actions should you take? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure Azure Firewall with a route to the VPN gateway for on-premises traffic.
Option A is correct: UDRs force spoke traffic to the firewall. Option B is correct: The firewall must be configured to route traffic to the VPN gateway. Option C is correct: Propagating gateway routes ensures the route table includes routes from the VPN gateway. Option D is incorrect because VNet peering does not inspect traffic. Option E is incorrect because BGP does not force traffic through the firewall.
Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

Common exam traps
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Detailed technical explanation
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.
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 to study next
Got this wrong? Here's your next step.
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related AZ-500 subnetting questions on CIDR, address ranges, and subnet selection.
