Question 236 - AZ-700 discussion

To ensure that only hosts on VNET1 can access theslcnage42150372storage account and that access occurs over the Azure backbone network, you can useAzure 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 theslcnage42150372storage 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 settingsif 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 settingsand 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 listedunder 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 theslcnage42150372storage account, and that all access occurs over the secure Azure backbone network.
