A hub VNet already has a VPN gateway connected to on-premises. A spoke VNet must send on-premises traffic through the hub gateway without deploying its own gateway. Which peering settings are needed?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Distractor review

Enable forwarded traffic on both peerings and add a route table to the spoke subnet.

Forwarded traffic helps with transit scenarios, but it does not by itself enable gateway reuse.

B

Best answer

Enable gateway transit on the hub peering and use remote gateways on the spoke peering.

This combination lets the spoke VNet use the hub gateway for on-premises connectivity.

C

Distractor review

Create a private endpoint in the spoke VNet and route on-premises traffic through it.

Private endpoints are for PaaS access and do not provide gateway transit to on-premises networks.

D

Distractor review

Deploy a second VPN gateway in the spoke and connect it in active-active mode.

The requirement explicitly says the spoke should not deploy its own gateway.

Common exam trap

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.

Technical deep dive

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.

FAQ

Questions learners often ask

What does this AZ-104 question test?

CIDR notation defines the prefix length.

What is the correct answer to this question?

The correct answer is: Enable gateway transit on the hub peering and use remote gateways on the spoke peering. — To let a spoke VNet use the hub’s VPN gateway, Azure peering must be configured for gateway transit. The hub side must allow gateway transit, and the spoke side must use remote gateways. That combination tells Azure to advertise the hub gateway as the route to on-premises resources without deploying an additional gateway in the spoke. This is a common hub-and-spoke connectivity pattern in Azure. Why others are wrong: Forwarded traffic can support transit, but it does not replace the gateway-transit and remote-gateway settings required for shared gateway use. Private endpoints are unrelated to on-premises routing. Deploying another gateway defeats the stated requirement to reuse the hub gateway and adds unnecessary cost and complexity.
