Topic 2, Litware. Inc Case Study 1
Overview
Litware. Inc. is a financial company that has a main datacenter in Boston and 20 branch offices across the United States. Users have Android, iOS, and Windows 10 devices.
Existing Environment:
Hybrid Environment
The on-prernises network contains an Active Directory forest named litwareinc.com that syncs to an Azure Active Directory (Azure AD) tenant named litwareinc.com by usinq Azure AD Connect.
All the offices connect to a virtual network named Vnetl by using a Site-to-Site VPN connection.
Azure Environment
Litware has an Azure subscription named Sub1 that is linked to the litwareinc.com Azure AD tenant. Sub1 contains resources in the East US Azure region as shown in the following table.
There is bidirectional peering between Vnet1 and Vnet2. There is bidirectional peering between Vnet1 and Vnet3. Currently, Vnet2 and Vnet3 cannot communicate directly.
Requirements:
Business Requirements
Litware wants to minimize costs whenever possible, as long as all other requirements are met.
Virtual Networking Requirements
Litware identifies the following virtual networking requirements:
* Direct the default route of 0.0.0.0/0 on Vnet2 and Vnet3 to the Boston datacenter over an ExpressRoute circuit.
* Ensure that the records in the cloud.litwareinc.com zone can be resolved from the on-premises locations.
* Automatically register the DNS names of Azure virtual machines to the cloud.litwareinc.com zone.
* Minimize the size of the subnets allocated to platform-managed services.
* Allow traffic from VMScaleSet1 to VMScaleSet2 on the TCP port 443 only.
Hybrid Networking Requirements
Litware identifies the following hybrid networking requirements:
* Users must be able to connect to Vnet1 by using a Point-to-Site (P2S) VPN when working remotely.
Connections must be authenticated by Azure AD.
* Latency of the traffic between the Boston datacenter and all the virtual networks must be minimized.
* The Boston datacenter must connect to the Azure virtual networks by using an ExpressRoute FastPath connection.
* Traffic between Vnet2 and Vnet3 must be routed through Vnet1.
PaaS Networking Requirements
Litware identifies the following networking requirements for platform as a service (PaaS):
* The storage1 account must be accessible from all on-premises locations without exposing the public endpoint of storage1.
* The storage2 account must be accessible from Vnet2 and Vnet3 without exposing the public endpoint of storage2.
You have an Azure virtual network named Vnet1 and an on-premises network.
The on-premises network has policy-based VPN devices. In Vnet1, you deploy a virtual network gateway named GW1 that uses a SKU of VpnGw1 and is route-based.
You have a Site-to-Site VPN connection for GW1 as shown in the following exhibit.
You need to ensure that the on-premises network can connect to the route-based GW1. What should you do before you create the connection?

You have an Azure application gateway configured for a single website that is available at https://www.
contoso.com.
The application gateway contains one backend pool and one rule. The backend pool contains two backend servers. Each backend server has an additional website that is available on port 8080.
You need to ensure that if port 8080 is unavailable on a backend server, all the traffic for https://www.contoso.
com is redirected to the other backend server.

Task 8
You plan to deploy an appliance to subnet3-2- The appliance will perform packet inspection and will have an IP address of 10.3.2.100.
You need to ensure that all traffic to the internet from subnet3-1 is forwarded to the appliance for inspection.
You plan to deploy an appliance to subnet3-2- The appliance will perform packet inspection and will have an IP address of 10.3.2.100.
You need to ensure that all traffic to the internet from subnet3-1 is forwarded to the appliance for inspection.
正解：
See the Explanation below for step by step instructions.
Explanation:
To ensure that all traffic to the internet from subnet3-1 is forwarded to the appliance in subnet3-2 for packet inspection, you can use User-Defined Routes (UDRs) to direct the traffic. Here's how you can do it:
* Navigate to the Azure Portal.
* Search for "Route tables" 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 route table (e.g., RouteTable-Subnet3-1).
* Region: Select the region where your virtual network is located.
* Click on "Review + create" and then "Create".
* Navigate to the newly created route table.
* Select "Routes" from the left-hand menu.
* Click on "Add" to create a new route.
* Enter the following details:
* Route name: Enter a name for the route (e.g., RouteToAppliance).
* Address prefix: Enter 0.0.0.0/0 to route all internet traffic.
* Next hop type: Select Virtual appliance.
* Next hop address: Enter the IP address of the appliance (10.3.2.100).
* Click on "OK" to add the route.
* Navigate to the route table.
* Select "Subnets" from the left-hand menu.
* Click on "Associate".
* Select the virtual network that contains subnet3-1.
* Select subnet3-1 from the list of subnets.
* Click on "OK".
* User-Defined Routes (UDRs): These allow you to control the routing of traffic within your virtual network. By defining a route that directs all internet-bound traffic to the appliance, you ensure that the traffic is inspected before it reaches the internet1.
* Virtual Appliance: This is a network appliance that performs specific functions, such as packet inspection, and is treated as a next hop in the routing table2.
* Route Table Association: Associating the route table with subnet3-1 ensures that all traffic from this subnet follows the defined routes.
Step-by-Step SolutionStep 1: Create a Route TableStep 2: Add a Route to the Route TableStep 3: Associate the Route Table with Subnet3-1ExplanationBy following these steps, you can ensure that all internet-bound traffic from subnet3-1 is forwarded to the appliance in subnet3-2 for inspection, thereby enhancing your network security.

Explanation:
Yes, Yes, Yes
NSG rules applied to the subnet hosting the private endpoint are not applied to the private endpoint.So the NSG1 doesn't limit storage access from either VM1 or VM2. https://docs.microsoft.com/en-us/azure/storage
