AZ-700 Azure Routing

Question 1

What is the correct priority order when multiple routes exist for the same address prefix in an Azure subnet?

Accepted Answer

User Defined Routes > BGP routes > System routes

Answer

User Defined Routes take the highest priority, followed by BGP-learned routes, and finally system routes when routes share the same prefix.

Question 2

You need to prevent all internet-bound traffic from a specific Azure subnet. Which UDR configuration achieves this?

Accepted Answer

Create a route for 0.0.0.0/0 with next hop type 'None'

Answer

A UDR with destination 0.0.0.0/0 and next hop 'None' creates a black hole route that silently drops all internet-bound traffic.

Question 3

A subnet route table has a custom route for 10.0.0.0/16 pointing to a virtual appliance, and a system route for 10.0.1.0/24 (a subnet within 10.0.0.0/16) pointing to VnetLocal. Traffic destined for 10.0.1.5 will use which route?

Accepted Answer

The /24 system route to VnetLocal

Answer

Azure uses longest prefix match, so the more specific /24 route wins over the /16 route regardless of route source.

Question 4

Which next hop type in a User Defined Route directs traffic to a network virtual appliance (NVA) running in Azure?

Accepted Answer

VirtualAppliance

Answer

The 'VirtualAppliance' next hop type routes traffic to a specified private IP address, typically an NVA such as a firewall or router VM.

Question 5

When gateway route propagation is disabled on a subnet's route table, what is the effect?

Accepted Answer

Routes learned by the VPN or ExpressRoute gateway are not added to the subnet's effective routes

Answer

Disabling gateway route propagation prevents the VPN or ExpressRoute gateway from automatically injecting its learned on-premises routes into the subnet's route table.
