Azure Routing and System Routes Quiz

Azure Routing

• System routes have the highest priority in Azure routing.
• The priority order of route types in Azure routing, from highest to lowest, is: System, UDR (User-Defined Route), BGP (Border Gateway Protocol).
• System routes always take precedence regardless of the priority order.
• When there are multiple routes with the same prefix, the route with the longest prefix match is preferred.

UDR and Route Server

• UDR stands for User-Defined Route in Azure routing.
• Dynamic routing between network virtual appliances and the virtual network in Azure is allowed by UDR.
• The purpose of the Azure Route Server is to enable the propagation of routes from the network virtual appliances to the virtual network.

Traffic Flow and Inspection

• VM traffic in Azure always goes through the system route first.
• To inspect traffic with a FortiGate VM, a route needs to be created.

SDN and Load Balancers

• SDN stands for Software-Defined Networking in Azure routing.
• The Azure Load Balancer that can distribute traffic among healthy instances of services defined in a load-balanced set is the Internal Load Balancer.
• The Azure Load Balancer that can be configured to forward external traffic to a specific VM is the Public Load Balancer.
• The Azure Load Balancer that provides low latency and high throughput, and can scale up to millions of flows for all TCP and UDP applications is the Azure Load Balancer with HA Ports.
• The Azure Load Balancer that supports inbound and outbound scenarios is the Azure Application Gateway.
• The Azure Load Balancer that can scale applications and create high availability for services is the Azure Load Balancer.

Public IP Addresses

• The SKU of public IP addresses in Azure that can be static or dynamic for IP-v4, and dynamic for IP-v6 is the Standard SKU.
• The SKU of public IP addresses in Azure that is secure by default and requires the configuration of network security groups to allow inbound traffic is the Standard SKU.
• The SKU of public IP addresses in Azure that can be upgraded to Standard after creation is the Basic SKU.
• The SKU of public IP addresses in Azure that allows public IP addresses to be used with cross-region load balancers is the Standard SKU.
• The SKU of public IP addresses in Azure that is recommended to use with network security groups to restrict traffic is the Standard SKU.
