Click on “Next: Disks”, configure the disks as needed, and then click on “Next: Networking”.

In the Networking tab, select the virtual network (VNet-FranceCentral) and subnet (Subnet-1) created earlier.

Complete the remaining configuration steps and click on “Review + create” and then “Create”.

Explanation

Virtual Network: A virtual network in Azure allows you to create a logically isolated network that can host your Azure resources.

Address Space: The address space 10.5.1.0/24 ensures that the VMs are in a specific network segment.

Subnet: Subnets allow you to segment the virtual network into smaller, manageable sections.

Region: Deploying the virtual network and VMs in the France Central region ensures that the resources are physically located in that region.

By following these steps, you can ensure that your Azure virtual machines in the France Central region are deployed within the specified IP address range of 10.5.1.0/24.

To ensure that all traffic to the internet from subnet3-1 is forwarded to the appliance in subnet3-2 for packet inspection, you can use User-Defined Routes (UDRs) to direct the traffic. Here’s how you can do it:

Navigate to the Azure Portal.

Search for “Route tables” and select it.

Click on “Create”.

Enter the following details:

Subscription: Select your subscription.

Resource Group: Select an existing resource group or create a new one.

Name: Enter a name for the route table (e.g., RouteTable-Subnet3-1).

Region: Select the region where your virtual network is located.

Click on “Review + create” and then “Create”.

Navigate to the newly created route table.

Select “Routes” from the left-hand menu.

Click on “Add” to create a new route.

Enter the following details:

Route name: Enter a name for the route (e.g., RouteToAppliance).

Address prefix: Enter 0.0.0.0/0 to route all internet traffic.

Next hop type: Select Virtual appliance.

Next hop address: Enter the IP address of the appliance (10.3.2.100).

Click on “OK” to add the route.

Navigate to the route table.

Select “Subnets” from the left-hand menu.

Click on “Associate”.

Select the virtual network that contains subnet3-1.

Select subnet3-1 from the list of subnets.

Click on “OK”.

User-Defined Routes (UDRs): These allow you to control the routing of traffic within your virtual network. By defining a route that directs all internet-bound traffic to the appliance, you ensure that the traffic is inspected before it reaches the internet1.

Virtual Appliance: This is a network appliance that performs specific functions, such as packet inspection, and is treated as a next hop in the routing table2.

Route Table Association: Associating the route table with subnet3-1 ensures that all traffic from this subnet follows the defined routes.

Step-by-Step SolutionStep 1: Create a Route TableStep 2: Add a Route to the Route TableStep 3: Associate the Route Table with Subnet3-1ExplanationBy following these steps, you can ensure that all internet-bound traffic from subnet3-1 is forwarded to the appliance in subnet3-2 for inspection, thereby enhancing your network security.

To achieve the task of ensuring that virtual machines on VNET1 and VNET2 are included automatically in a DNS zone named contoso.azure, and that they can resolve the names of the virtual machines on either virtual network, you can follow these steps:

Step-by-Step Solution

Step 1: Create a Private DNS Zone

Navigate to the Azure Portal.

Search for “Private DNS zones” in the search bar and select it.

Click on “Create”.

Enter the DNS zone name as contoso.azure.

Select the appropriate subscription and resource group.

Click on “Review + create” and then “Create”.

Step 2: Link VNET1 and VNET2 to the DNS Zone

Go to the newly created DNS zone (contoso.azure).

Select “Virtual network links” from the left-hand menu.

Click on “Add”.

Enter a name for the link (e.g., VNET1-link).

Select the subscription and virtual network (VNET1).

Enable auto-registration to ensure that VMs are automatically registered in the DNS zone.

Click on “OK”.

Repeat the process for VNET2.

Step 3: Configure DNS Settings for VNET1 and VNET2

Navigate to VNET1 in the Azure Portal.

Select “DNS servers” under the “Settings” section.

Ensure that the DNS server is set to “Default (Azure-provided)”.

Repeat the process for VNET2.

Step 4: Verify Name Resolution

Deploy a virtual machine in VNET1 and another in VNET2.

Connect to the virtual machines using Remote Desktop Protocol (RDP) or Secure Shell (SSH).

Test name resolution by pinging the VM in VNET2 from the VM in VNET1 using its hostname (e.g., ping .contoso.azure).

Explanation

Private DNS Zone: This allows you to manage and resolve domain names in a private network without exposing them to the public internet.

Virtual Network Links: Linking VNET1 and VNET2 to the DNS zone ensures that VMs in these networks can register their DNS records automatically.

Auto-registration: This feature automatically registers the DNS records of VMs in the linked virtual networks, simplifying management.

DNS Settings: Using Azure-provided DNS ensures that the VMs can resolve each other’s names without additional configuration.

By following these steps, you ensure that virtual machines on VNET1 and VNET2 are included automatically in the DNS zone contoso.azure and can resolve each other’s names seamlessly.
