AZ-700 Practice Exam Questions and Answers

Here are the steps and explanations for ensuring that connections to the storage34280945 storage account can be made by using an IP address in the 10.1.1.0/24 range and the name stor-age34280945.pnvatelinlcblob.core.windows.net:

To allow access from a specific IP address range, you need to configure the Azure Storage firewall and virtual network settings for your storage account. You can do this in the Azure portal by selecting your storage account and then selecting Networking under Settings1.

On the Networking page, select Firewalls and virtual networks, and then select Selected networks under Allow access from1. This will block all access to your storage account except from the networks or resources that you specify.

Under Firewall, select Add rule, and then enter 10.1.1.0/24 as the IP address or range. You can also enter an optional rule name and description1. This will allow access from any IP address in the 10.1.1.0/24 range.

Select Save to apply your changes1.

To map a custom domain name to your storage account, you need to create a CNAME record with your domain provider that points to your storage account endpoint2. A CNAME record is a type of DNS record that maps a source domain name to a destination domain name.

Sign in to your domain registrar’s website, and then go to the page for managing DNS settings2.

Create a CNAME record with the following information2:

Source domain name: stor-age34280945.pnvatelinlcblob.core.windows.net

Destination domain name: stor-age34280945.pnvatelinlcblob.core.windows.net

Save your changes and wait for the DNS propagation to take effect2.

To register the custom domain name with Azure, you need to go back to the Azure portal and select your storage account. Then select Custom domain under Blob service2.

On the Custom domain page, enter stor-age34280945.pnvatelinlcblob.core.windows.net as the custom domain name and 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 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.

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.
