Here are the steps and explanations for configuring VNET1 to log all events and metrics and query them by using KQL:

To enable logging for VNET1, you need to create a diagnostic setting that collects the platform metrics and logs from the virtual network and routes them to one or more destinations. You can choose to send the data to a Log Analytics workspace, a storage account, an event hub, or a partner solution1.

To create a diagnostic setting, you need to go to the Azure portal and select your virtual network. Then select Diagnostic settings under Monitoring and select + Add diagnostic setting1.

On the Add diagnostic setting page, enter or select the following information:

Diagnostic setting name: Type a unique name for your diagnostic setting.

Destination details: Select the destination where you want to send the data. For example, you can select Send to Log Analytics workspace and choose your workspace from the list.

Log: Select the categories of logs that you want to collect. For VNET1, you can select NetworkSecurityGroupEvent and NetworkSecurityGroupRuleCounter as the log categories2.

Metric: Select AllMetrics to collect all the platform metrics for VNET12.

Select Save to create your diagnostic setting1.

To query the events and metrics from the Azure portal by using KQL, you need to go to the Log Analytics workspace that you selected as the destination. Then select Logs under General and enter your KQL query in the query editor3.

For example, you can use the following KQL query to get the top 10 network security group events for VNET1 in the last 24 hours:

NetworkSecurityGroupEvent

| where TimeGenerated > ago(24h)

| where ResourceId contains "VNET1"

| summarize count() by EventID

| top 10 by count_

Copy

Select Run to execute your query and view the results in a table or a chart3.

Inbound Processing: Applying the policy in the inbound section ensures that the requests are filtered before they reach your API.

By following these steps, you can configure a policy in Azure API Management that restricts access to your API to only those requests originating from IP addresses in Canada, thereby enhancing security and compliance

No

subnet1(WM1->NSG1 outbound->NSG10 outbound)->subnet2(NSG1 inbound->NSG11 inbound->VM2)

Yes

NSG10 blocks ICMP from VNet4 (source 10.10.0.0/16) but it is not blocked from VM2ג€™s subnet (VNet1/Subnet2).

No

NSG11 blocks RDP (port TCP 3389) destined for ג€˜VirtualNetworkג€™. VirtualNetwork is a service tag and means the address space of the virtual network (VNet1) which in this case is 10.1.0.0/16. Therefore, RDP traffic from subnet2 to anywhere else in VNet1 is blocked.

NGS1 only

VM2, VM3, VM4 and VM5

There is no virtual network peering between VM4’s VNet (VNet3) and VM5’s VNet (VNet4). To enable the VMs to communicate over the Microsoft backbone network a VNet peering is required between VNet3 and VNet4.

For the first question, only ExpressRoute GW SKU Ultra Performance support FastPath feature.

For the second question, vnet1 will connect to ExpressRoute gw, once Vnet1 peers with Vnet2, the traffic from on-premise network will bypass GW and Vnet1, directly goes to Vnet2, while this feature is under public preview.

====Reference

ExpressRoute virtual network gateway is designed to exchange network routes and route network traffic. FastPath is designed to improve the data path performance between your on-premises network and your virtual network. When enabled, FastPath sends network traffic directly to virtual machines in the virtual network, bypassing the gateway.

To configure FastPath, the virtual network gateway must be either:

Administrative Operations: Monitoring these operations helps in tracking changes and maintaining the security and integrity of your virtual network.

By following these steps, you can ensure that the owner of VNET3 receives timely alerts for any administrative operations performed on the virtual network, helping to maintain oversight and security.

Here are the steps and explanations for ensuring that hosts on VNET2 can access hosts on both VNET1 and VNET3, but hosts on VNET1 and VNET3 cannot communicate through VNET2:

To connect different virtual networks in Azure, you need to use virtual network peering. Virtual network peering allows you to create low-latency, high-bandwidth connections between virtual networks without using gateways or the internet1.

To create a virtual network peering, you need to go to the Azure portal and select your virtual network. Then select Peerings under Settings and select + Add2.

On the Add peering page, enter or select the following information:

Name: Type a unique name for the peering from the source virtual network to the destination virtual network.

Virtual network deployment model: Select Resource manager.

Subscription: Select the subscription that contains the destination virtual network.

Virtual network: Select the destination virtual network from the list or enter its resource ID.

Name of the peering from [destination virtual network] to [source virtual network]: Type a unique name for the peering from the destination virtual network to the source virtual network.

Configure virtual network access settings: Select Enabled to allow resources in both virtual networks to communicate with each other.

Allow forwarded traffic: Select Disabled to prevent traffic that originates from outside either of the peered virtual networks from being forwarded through either of them.

Allow gateway transit: Select Disabled to prevent either of the peered virtual networks from using a gateway in the other virtual network.

Use remote gateways: Select Disabled to prevent either of the peered virtual networks from using a gateway in the other virtual network as a transit point to another network.

Select Add to create the peering2.

Repeat the previous steps to create peerings between VNET2 and VNET1, and between VNET2 and VNET3. This will allow hosts on VNET2 to access hosts on both VNET1 and VNET3.

To prevent hosts on VNET1 and VNET3 from communicating through VNET2, you need to use network security groups (NSGs) to filter traffic between subnets. NSGs are rules that allow or deny inbound or outbound traffic based on source or destination IP address, port, or protocol3.

To create an NSG, you need to go to the Azure portal and select Create a resource. Search for network security group and select Network security group. Then select Create4.

On the Create a network security group page, enter or select the following information:

Subscription: Select your subscription name.

Resource group: Select your resource group name.

Name: Type a unique name for your NSG.

Region: Select the same region as your virtual networks.

Select Review + create and then select Create to create your NSG4.

To add rules to your NSG, you need to go to the Network security groups service in the Azure portal and select your NSG. Then select Inbound security rules or Outbound security rules under Settings and select + Add4.

On the Add inbound security rule page or Add outbound security rule page, enter or select the following information:

Source or Destination: Select CIDR block.

Source CIDR blocks or Destination CIDR blocks: Enter the IP address range of the source or destination subnet that you want to filter. For example, 10.0.1.0/24 for VNET1 subnet 1, 10.0.2.0/24 for VNET2 subnet 1, and 10.0.3.0/24 for VNET3 subnet 1.

Protocol: Select Any to apply the rule to any protocol.

Action: Select Deny to block traffic from or to the source or destination subnet.

Priority: Enter a number between 100 and 4096 that indicates the order of evaluation for this rule. Lower numbers have higher priority than higher numbers.

Name: Type a unique name for your rule.

Select Add to create your rule4.

Repeat the previous steps to create inbound and outbound rules for your NSG that deny traffic between VNET1 and VNET3 subnets. For example, you can create an inbound rule that denies traffic from 10.0.1.0/24 (VNET1 subnet 1) to 10.0.3.0/24 (VNET3 subnet 1), and an outbound rule that denies traffic from 10.0.3.0/24 (VNET3 subnet 1) to 10.0.1.0/24 (VNET1 subnet 1).

To associate your NSG with a subnet, you need to go to the Virtual networks service in the Azure portal and select your virtual network. Then select Subnets under Settings and select the subnet that you want to associate with your NSG5.

On the Edit subnet page, under Network security group, select your NSG from the drop-down list. Then select Save5.

Repeat the previous steps to associate your NSG with the subnets in VNET1 and VNET3 that you want to isolate from each other.

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.

Here are the steps and explanations for ensuring that subnet4-3 can accommodate 507 hosts:

To determine the subnet size that can accommodate 507 hosts, you need to use the formula: number of hosts = 2^(32 - n) - 2, where n is the number of bits in the subnet mask1. You need to find the value of n that satisfies this equation for 507 hosts.

To solve this equation, you can use trial and error or a binary search method. For example, you can start with n = 24, which is the default subnet mask for Class C networks. Then, plug in the value of n into the formula and see if it is too big or too small for 507 hosts.

If you try n = 24, you get number of hosts = 2^(32 - 24) - 2 = 254, which is too small. You need to increase the value of n to get a larger number of hosts.

If you try n = 25, you get number of hosts = 2^(32 - 25) - 2 = 510, which is just enough to accommodate 507 hosts. You can stop here or try a smaller value of n to see if it still works.

If you try n = 26, you get number of hosts = 2^(32 - 26) - 2 = 254, which is too small again. You need to decrease the value of n to get a larger number of hosts.

Therefore, the smallest value of n that can accommodate 507 hosts is n = 25. This means that the subnet mask for subnet4-3 should be /25 or 255.255.255.128 in dot-decimal notation1.

To change the subnet mask for subnet4-3, you need to go to the Azure portal and select your virtual network. Then select Subnets under Settings and select subnet4-3 from the list2.

On the Edit subnet page, under Address range (CIDR block), change the value from /24 to /25. Then select Save2.

To ensure that only hosts on VNET1 can access the slcnage42150372 storage account and that access occurs over the Azure backbone network, you can use Azure Private Endpoints. This method secures the connection by assigning a private IP address from your virtual network to the storage account, ensuring that traffic does not traverse the public internet.

Step-by-Step Solution

Step 1: Create a Private Endpoint for the Storage Account

Navigate to the Azure Portal.

Search for “Storage accounts” and select the slcnage42150372 storage account.

In the storage account blade, select “Networking” under the “Security + networking” section.

Under “Private endpoint connections”, click on “Add private endpoint”.

Enter the following details:

Name: Enter a name for the private endpoint (e.g., PrivateEndpoint-VNET1).

Region: Select the same region as your virtual network (VNET1).

Click on “Next: Resource”.

Step 2: Configure the Resource

Select “Target sub-resource”: Choose the storage service you want to connect to (e.g., blob, file, queue, table).

Click on “Next: Virtual network”.

Step 3: Select the Virtual Network and Subnet

Select the virtual network: Choose VNET1.

Select the subnet: Choose the appropriate subnet within VNET1.

Click on “Next: Configuration”.

Step 4: Configure DNS Integration (Optional)

Configure DNS settings if needed to ensure proper name resolution within your virtual network.

Click on “Next: Tags”, add any tags if necessary, and then click on “Review + create”.

Review your settings and click on “Create”.

Step 5: Restrict Public Network Access

Navigate back to the storage account.

Select “Networking” under the “Security + networking” section.

Under “Firewalls and virtual networks”, select “Selected networks”.

Ensure that only VNET1 is listed under the virtual networks section.

Click on “Save”.

Explanation

Private Endpoints: These provide secure connectivity to Azure services by assigning a private IP address from your VNet to the service, ensuring that traffic stays within the Azure backbone network12.

Firewall and Virtual Networks: Configuring the storage account to allow access only from selected networks (VNET1) ensures that no other network can access the storage account3.

By following these steps, you can ensure that only hosts on VNET1 can access the slcnage42150372 storage account, and that all access occurs over the secure Azure backbone network.

To ensure that hosts on VNET1 and VNET2 can communicate with minimal latency, you can use Virtual Network Peering. This method connects the two virtual networks directly through the Microsoft backbone network, ensuring low-latency and high-bandwidth communication.

Step-by-Step Solution

Step 1: Set Up Virtual Network Peering

Navigate to the Azure Portal.

Search for “Virtual networks” and select VNET1.

In the left-hand menu, select “Peerings” under the “Settings” section.

Click on “Add” to create a new peering.

Enter the following details:

Name: Enter a name for the peering (e.g., VNET1-to-VNET2).

Peer virtual network: Select VNET2.

Allow virtual network access: Ensure this is enabled.

Allow forwarded traffic: Enable if needed.

Allow gateway transit: Enable if needed.

Click on “Add”.

Step 2: Configure Peering on VNET2

Navigate to VNET2 in the Azure Portal.

In the left-hand menu, select “Peerings” under the “Settings” section.

Click on “Add” to create a new peering.

Enter the following details:

Name: Enter a name for the peering (e.g., VNET2-to-VNET1).

Peer virtual network: Select VNET1.

Allow virtual network access: Ensure this is enabled.

Allow forwarded traffic: Enable if needed.

Allow gateway transit: Enable if needed.

Click on “Add”.

Explanation

Virtual Network Peering: This feature connects two virtual networks in the same or different regions, allowing resources in both networks to communicate with each other as if they were part of the same network. The traffic between peered virtual networks uses the Microsoft backbone infrastructure, ensuring low latency and high bandwidth12.

Allow Virtual Network Access: This setting ensures that the virtual networks can communicate with each other.

Allow Forwarded Traffic: This setting allows traffic forwarded from a network security appliance in the peered virtual network.

Allow Gateway Transit: This setting allows the peered virtual network to use the gateway in the local virtual network.

By following these steps, you can ensure that hosts on VNET1 and VNET2 can communicate with minimal latency, leveraging the high-speed Microsoft backbone network.

To create an Azure Firewall instance, you need to go to the Azure portal and select Create a resource. Type firewall in the search box and press Enter. Select Firewall and then select Create1.

To assign an IP address from the address range of 10.1.255.0/24 to the firewall, you need to select a public IP address that belongs to that range. You can either create a new public IP address or use an existing one1.

To use a new Premium firewall policy named FW-policy1, you need to select Premium as the Firewall tier and create a new policy with the name FW-policy12. A Premium firewall policy allows you to configure advanced features such as TLS Inspection, IDPS, URL Filtering, and Web Categories3.

To route traffic directly to the internet, you need to enable SNAT (Source Network Address Translation) for the firewall. SNAT allows the firewall to use its public IP address as the source address for outbound traffic4.

To archive all the metrics of VNET1 to an existing storage account, you can use Azure Monitor’s diagnostic settings. Here’s how you can do it:

Step-by-Step Solution

Step 1: Navigate to VNET1 in the Azure Portal

Select the metrics you want to archive. You can choose from various metrics like TotalBytesReceived, TotalBytesSent, etc.

Under “Destination details”, select “Archive to a storage account”.

Choose the existing storage account where you want to archive the metrics.

Configure the retention period if needed.

Step 4: Save the Configuration

Review your settings to ensure everything is correct.

Click on “Save” to apply the diagnostic setting.

Explanation

Diagnostic Settings: These allow you to collect and route metrics and logs from your Azure resources to various destinations, including storage accounts, Log Analytics workspaces, and Event Hubs.

Metrics: Metrics provide numerical data about the performance and health of your resources. Archiving these metrics helps in long-term analysis and compliance.

Storage Account: Using an existing storage account ensures that the metrics are stored securely and can be accessed for future analysis.

By following these steps, you can ensure that all the metrics of VNET1 are archived to your existing storage account, enabling you to monitor and analyze the performance and health of your virtual network over time.

To deploy a firewall to subnetl-2, you need to create a network virtual appliance (NVA) in the same virtual network as subnetl-2. An NVA is a virtual machine that performs network functions, such as firewall, routing, or load balancing1.

To create an NVA, you need to create a virtual machine in the Azure portal and select an image that has the firewall software installed. You can choose from the Azure Marketplace or upload your own image2.

To assign the IP address of 10.1.2.4 to the NVA, you need to create a static private IP address for the network interface of the virtual machine. You can do this in the IP configurations settings of the network interface3.

To ensure that traffic from subnetl-1 to the IP address range of 192.168.10.0/24 is routed through the NVA, you need to create a user-defined route (UDR) table and associate it with subnetl-1. A UDR table allows you to override the default routing behavior of Azure and specify custom routes for your subnets4.

To create a UDR table, you need to go to the Route tables service in the Azure portal and select + Create. You can give a name and a resource group for the route table5.

To create a custom route, you need to select Routes in the route table and select + Add. You can enter the following information for the route5:

Destination: 192.168.10.0/24

Next hop type: Virtual appliance

Next hop address: 10.1.2.4

To associate the route table with subnetl-1, you need to select Subnets in the route table and select + Associate. You can select the virtual network and subnet that you want to associate with the route table5.

Click on “Create” and then “Azure virtual machine”.

Enter the following details:

Subscription: Select your subscription.

Resource Group: Select the same resource group used for the virtual network.

Virtual machine name: Enter a name for the VM.

Region: Select France Central.

Image: Select the desired OS image.

Size: Select the appropriate VM size.

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.

Box 2: One NSG

The minimum requirement is one NSG. You could attach the NSG to VMScaleSet1 and restrict outbound traffic, or you could attach the NSG to VMScaleSet2 and restrict inbound traffic. Either way you would need two custom NSG rules.

Box 1: Two custom rules

With the NSG attached to VMScaleSet2, you would need to create a custom rule blocking all traffic from VMScaleSet1. Then you would need to create another custom rule with a higher priority than the first rule that allows traffic on port 443.

The default rules in the NSG will allow all other traffic to VMScaleSet2.

VNet 1 will get the default from BGP and propagate it to VNET 2 and 3
