Zorluk: KolayConfigure User-Defined Routes and Routing Tables

You configure routing for an Azure subnet named `Subnet1`. You deploy a third-party firewall virtual machine to act as a Network Virtual Appliance (NVA) in a subnet named `Subnet-DMZ` within the same virtual network. You need to route all outbound internet traffic from `Subnet1` through the NVA. You create a custom route table and associate it with `Subnet1`. Which route configuration must you add to the route table?

  1. A
    Destination prefix of 0.0.0.0/00.0.0.0/0 and next hop type of Internet
  2. Destination prefix of 0.0.0.0/00.0.0.0/0 and next hop type of Virtual applianceCevap
  3. C
    Destination prefix of 0.0.0.0/00.0.0.0/0 and next hop type of Virtual network gateway
  4. D
    Destination prefix of * and next hop type of Virtual appliance

Cevap

A route with a destination prefix of 0.0.0.0/00.0.0.0/0 and next hop type of Virtual appliance.
To route all outbound internet traffic through a Network Virtual Appliance (NVA), you must define a default route with the destination prefix 0.0.0.0/00.0.0.0/0 and set the next hop type to Virtual appliance, specifying the NVA's private IP address as the next hop IP address.

Adım Adım Çözüm

1
Identify the destination prefix required to capture all outbound internet traffic.
The destination prefix must be 0.0.0.0/00.0.0.0/0.
In Azure routing, the 0.0.0.0/00.0.0.0/0 address prefix represents the default route containing all IP addresses not matched by other routes.
2
Determine the correct next hop type to route traffic through a custom firewall virtual machine.
The next hop type must be set to Virtual appliance.
A Virtual appliance next hop type specifies that traffic should be forwarded to a private IP address of a user-defined virtual machine acting as a firewall or router.

Anahtar Kavram

The configuration of user-defined routes to direct outbound internet traffic (0.0.0.0/00.0.0.0/0) to a Network Virtual Appliance (NVA) using the 'Virtual appliance' next hop type.
