You plan to deploy several virtual machines to subnet1-2.
You need to prevent all Azure hosts outside of subnetl-2 from connecting to TCP port 5585 on hosts on subnet1-2. The solution must minimize administrative effort.
Task 10

正解：
See the Explanation below for step by step instructions
Explanation:
To prevent all Azure hosts outside of subnet1-2 from connecting to TCP port 5585 on hosts within subnet1-2, you can use a Network Security Group (NSG). This solution is straightforward and minimizes administrative effort.
Step-by-Step Solution
Step 1: Create a Network Security Group (NSG)
Navigate to the Azure Portal.
Search for "Network security groups" 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 NSG (e.g., NSG-Subnet1-2).
Region: Select the region where your virtual network is located.
Click on "Review + create" and then "Create".
Step 2: Create an Inbound Security Rule
Navigate to the newly created NSG.
Select "Inbound security rules" from the left-hand menu.
Click on "Add" to create a new rule.
Enter the following details:
Source: Select Service Tag.
Source Service Tag: Select VirtualNetwork.
Source port ranges: Leave as *.
Destination: Select IP Addresses.
Destination IP addresses/CIDR ranges: Enter the IP range of subnet1-2 (e.g., 10.1.2.0/24).
Destination port ranges: Enter 5585.
Protocol: Select TCP.
Action: Select Deny.
Priority: Enter a priority value (e.g., 100).
Name: Enter a name for the rule (e.g., Deny-TCP-5585).
Click on "Add" to create the rule.
Step 3: Associate the NSG with Subnet1-2
Navigate to the virtual network that contains subnet1-2.
Select "Subnets" from the left-hand menu.
Select subnet1-2 from the list of subnets.
Click on "Network security group".
Select the NSG you created (NSG-Subnet1-2).
Click on "Save".
Explanation:
Network Security Group (NSG): NSGs are used to filter network traffic to and from Azure resources in an Azure virtual network. They contain security rules that allow or deny inbound and outbound traffic based on source and destination IP addresses, port, and protocol1.
Inbound Security Rule: By creating a rule that denies traffic on TCP port 5585 from any source outside of subnet1-2, you ensure that only hosts within subnet1-2 can connect to this port.
Association with Subnet: Associating the NSG with subnet1-2 ensures that the security rules are applied to all resources within this subnet.
By following these steps, you can effectively prevent all Azure hosts outside of subnet1-2 from connecting to TCP port 5585 on hosts within subnet1-2, while minimizing administrative effort.

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.

See the Explanation below for step by step instructions
Explanation:
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.
