Here are the steps and explanations for ensuring that requests for wwwjelecloud.com from any of your Azure virtual networks resolve to frontdoor1.azurefd.net:

To use a custom domain with your Azure Front Door, you need to create a CNAME record with your domain provider that points to the Front Door default frontend host. A CNAME record is a type of DNS record that maps a source domain name to a destination domain name1.

To create a CNAME record, you need to sign in to your domain registrar’s website and go to the page for managing DNS settings1.

Create a CNAME record with the following information1:

Source domain name: wwwjelecloud.com

Destination domain name: frontdoor1.azurefd.net

Save your changes and wait for the DNS propagation to take effect1.

To verify the custom domain, you need to go to the Azure portal and select your Front Door profile. Then select Domains under Settings and select Add2.

On the Add a domain page, select Non-Azure validated domain as the Domain type and enter wwwjelecloud.com as the Domain name. Then select Add2.

On the Domains page, select wwwjelecloud.com and select Verify. This will check if the CNAME record is correctly configured2.

Once the domain is verified, you can associate it with your Front Door endpoint. On the Domains page, select wwwjelecloud.com and select Associate endpoint. Then select your Front Door endpoint from the drop-down list and select Associate2.

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.

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.

Here are the steps and explanations for ensuring that all hosts deployed to subnet3-2 connect to the internet by using the same static public IP address:

To use the same static public IP address for multiple hosts, you need to create a NAT gateway and associate it with subnet3-2. A NAT gateway is a resource that performs network address translation (NAT) for outbound traffic from a subnet1. It allows you to use a single public IP address for multiple private IP addresses2.

To create a NAT gateway, you need to go to the Azure portal and select Create a resource. Search for NAT gateway, select NAT gateway, then select Create3.

On the Create a NAT gateway page, enter or select the following information and accept the defaults for the remaining settings:

Subscription: Select your subscription name

Resource group: Select your resource group

Name: Type a unique name for your NAT gateway

Region: Select the same region as your virtual network

Public IP address: Select Create new and type a name for your public IP address. Select Standard as the SKU and Static as the assignment method4.

Select Review + create and then select Create to create your NAT gateway3.

To associate the NAT gateway with subnet3-2, you need to go to the Virtual networks service in the Azure portal and select your virtual network.

On the Virtual network page, select Subnets under Settings, and then select subnet3-2 from the list.

On the Edit subnet page, under NAT gateway, select your NAT gateway from the drop-down list. Then select Save.

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.
