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

System routes > BGP routes > User Defined Routes

Answer

BGP routes > User Defined Routes > System routes

Answer

System routes > User Defined Routes > BGP routes

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

Create a route for 0.0.0.0/0 with next hop type 'VirtualAppliance'

Answer

Delete the default system route for internet traffic

Answer

Create an NSG rule blocking all outbound traffic on port 443

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

The /16 custom route to the virtual appliance

Answer

Traffic is dropped because conflicting routes exist

Answer

The route with the lowest administrative distance

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

Internet

Answer

VnetLocal

Answer

VirtualNetworkGateway

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

All routing is disabled for the subnet

Answer

The subnet can no longer communicate with other subnets in the same VNet

Answer

BGP is disabled on all gateways connected to the VNet

Question 6

What is the purpose of viewing 'Effective Routes' for a virtual machine's network interface in Azure?

Accepted Answer

To display the merged routing table combining system, UDR, and BGP routes that the NIC actually uses

Answer

To see only the BGP routes advertised to on-premises routers

Answer

To show which routes are currently experiencing packet loss

Answer

To display routes validated by Azure's internal routing engine

Question 7

What is the default system route behavior for traffic in an Azure VNet that does not match any more specific route?

Accepted Answer

Traffic is dropped because no matching route exists

Answer

Traffic is sent to the nearest Azure datacenter for inspection

Answer

Traffic is forwarded to the VNet gateway for routing decisions

Answer

Traffic is broadcast to all subnets in the VNet
