Exam AZ-700 topic 3 question 32 discussion

Standard Virtual WAN is enabled due to the presence of a router in every virtual hub. This router is instantiated when the virtual hub is first created. If it has a router. Then it needs a routing table. Therefore two hubs. Two routing tables.

Question is flawed because VWAN creates its own routes. Yes you would technically need at least two route tables, but the question asks about creating them. You wouldn't need to create these since it will create the routes on its own

B is Honey as per this link https://learn.microsoft.com/en-us/azure/virtual-wan/about-virtual-hub-routing

The given answer is correct. The minimum number of route tables you can have for this setup is 2. By default, all connections are associated to a Default route table in a virtual hub. Each virtual hub has its own Default route table, which can be edited to add a static route(s). Routes added statically take precedence over dynamically learned routes for the same prefixes. https://learn.microsoft.com/en-us/azure/virtual-wan/about-virtual-hub-routing#association

Assuming the VNETs are using Hub virtual network connections, then each connection is associated to one route table. Associating a connection to a route table allows the traffic to be sent to the destination indicated as routes in the route table. The routing configuration of the connection will show the associated route table. Multiple connections can be associated to the same route table. All VPN, ExpressRoute, and User VPN connections are associated to the same (default) route table. By default, all connections are associated to a Default route table in a virtual hub. Each virtual hub has its own Default route table, which can be edited to add a static route(s). Routes added statically take precedence over dynamically learned routes for the same prefixes. Source: https://learn.microsoft.com/en-us/azure/virtual-wan/about-virtual-hub-routing#association As there is no indication in the question that connections were pointed to any specific route table, we would assume they would get added to the Default route table in each virtual hub. So 2 route tables total.
