AZ-800 Azure Route Tables and User-Defined Routes 3

Question 1

To allow an NVA to forward traffic destined for other IP addresses, what must be enabled on its network interface?

Accepted Answer

IP forwarding

Answer

IP forwarding must be enabled on the NVA's network interface so it can accept and forward packets addressed to IPs other than its own, acting as a router.

Question 2

Which Azure CLI command displays the effective routes for a network interface named 'myNIC' in resource group 'myRG'?

Accepted Answer

az network nic show-effective-route-table --name myNIC --resource-group myRG

Answer

The 'az network nic show-effective-route-table' command displays all effective routes (system routes plus UDRs) currently applied to a specific network interface.

Question 3

Can Azure system default routes (such as the local VNet route) be directly deleted?

Accepted Answer

No, system routes cannot be deleted, only overridden by UDRs with the same or more specific prefix

Answer

Azure system default routes cannot be deleted; they can only be overridden by creating UDRs with matching or more specific address prefixes that take precedence.

Question 4

At what level is an Azure route table applied?

Accepted Answer

At the subnet level, requiring explicit association with each subnet

Answer

Route tables must be explicitly associated with individual subnets; they are not automatically applied to all subnets in a VNet.

Question 5

Which of the following correctly lists the three RFC 1918 private address ranges used in Azure VNet planning?

Accepted Answer

10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16

Answer

RFC 1918 defines three private address ranges: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16, which are commonly used for Azure VNet address spaces.
