AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. 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. A key principle to apply: gateway transit allows a peered VNet to use another VNet's VPN/ExpressRoute gateway.. 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 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 the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable gateway transit on the hub peering and use remote gateways on the spoke peering.
Option B is correct because it enables gateway transit on the hub-side peering connection and uses remote gateways on the spoke-side peering connection. This configuration allows the spoke VNet to route on-premises traffic through the hub's VPN gateway without deploying its own gateway, leveraging the hub as a transit point.
Key principle: Gateway transit allows a peered VNet to use another VNet's VPN/ExpressRoute gateway.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable forwarded traffic on both peerings and add a route table to the spoke subnet.
Why it's wrong here
Forwarded traffic helps with transit scenarios, but it does not by itself enable gateway reuse.
✓
Enable gateway transit on the hub peering and use remote gateways on the spoke peering.
Why this is correct
This combination lets the spoke VNet use the hub gateway for on-premises connectivity.
Related concept
Gateway transit allows a peered VNet to use another VNet's VPN/ExpressRoute gateway.
✗
Create a private endpoint in the spoke VNet and route on-premises traffic through it.
Why it's wrong here
Private endpoints are for PaaS access and do not provide gateway transit to on-premises networks.
✗
Deploy a second VPN gateway in the spoke and connect it in active-active mode.
Why it's wrong here
The requirement explicitly says the spoke should not deploy its own gateway.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'forwarded traffic' with 'gateway transit' — forwarded traffic only allows VNet-to-VNet traffic forwarding, while gateway transit specifically enables a spoke to use a hub's VPN gateway for external connectivity.
Trap categories for this question
Scenario analysis trap
Forwarded traffic helps with transit scenarios, but it does not by itself enable gateway reuse.
Detailed technical explanation
How to think about this question
Gateway transit works by setting the 'Use remote gateways' flag on the spoke peering and 'Allow gateway transit' on the hub peering, which automatically propagates routes from the hub's VPN gateway to the spoke's route tables. This is implemented via BGP if the VPN gateway is configured for dynamic routing, or via static routes if using policy-based VPN. In a real-world scenario, this allows a spoke VNet to access on-premises resources without deploying its own VPN gateway, reducing cost and management overhead.
KKey Concepts to Remember
Gateway transit allows a peered VNet to use another VNet's VPN/ExpressRoute gateway.
The hub VNet's peering must have 'Gateway transit' enabled.
The spoke VNet's peering must have 'Use remote gateways' enabled.
This feature automatically propagates on-premises routes to the spoke VNet.
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
Gateway transit allows a peered VNet to use another VNet's VPN/ExpressRoute gateway.
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.
