Existing Environment:

Azure Network Infrastructure

Contoso has an Azure Active Directory (Azure AD) tenant named contoso.com.

The Azure subscription contains the virtual networks shown in the following table.

Vnet1 contains a virtual network gateway named GW1.

Azure Virtual Machines

The Azure subscription contains virtual machines that run Windows Server 2019 as shown in the following table.

The NSGs are associated to the network interfaces on the virtual machines. Each NSG has one custom security rule that allows RDP connections from the internet. The firewall on each virtual machine allows ICMP traffic.

An application security group named ASG1 is associated to the network interface of VM1.

Azure Private DNS Zones

The Azure subscription contains the Azure private DNS zones shown in the following table.

Zone1.contoso.com has the virtual network links shown in the following table.

Other Azure Resources

The Azure subscription contains additional resources as shown in the following table.

Requirements:

Virtual Network Requirements

Contoso has the following virtual networks requirements:

* Create a virtual network named Vnet6 in West US that will contain the following resources and configurations:

Two container groups that connect to Vnet6

Three virtual machines that connect to Vnet6

Allow VPN connections to be established to Vnet6

Allow the resources in Vnet6 to access KeyVault1, DB1, and Vnet1 over the Microsoft backbone network

* The virtual machines in Vnet4 and Vnet5 must be able to communicate over the Microsoft backbone network.

* A virtual machine named VM-Analyze will be deployed to Subnet1. VM-Analyze must inspect the outbound network traffic from Subnet2 to the internet.

Network Security Requirements

Contoso has the following network security requirements:

* Configure Azure Active Directory (Azure AD) authentication for Point-to-Site (P2S) VPN users.

* Enable NSG flow logs for NSG3 and NSG4.

* Create an NSG named NSG10 that will be associated to Vnet1/Subnet1 and will have the custom inbound security rules shown in the following table.

* Create an NSG named NSG11 that will be associated to Vnet1/Subnet2 and will have the custom outbound security rules shown in the following table.

HOTSPOT

You create NSG10 and NSG11 to meet the network security requirements.

For each of the following statements, select Yes it the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

Answer:

Explanation:

Yes

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 VM2™s subnet (VNet1/Subnet2).

No

NSG11 blocks RDP (port TCP 3389) destined for ˜VirtualNetwork™. 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.
