You have an Azure subscription that contains the following resources:

A virtual network that has a subnet named Subnet1

Two network security groups (NSGs) named NSG-VM1 and NSG-Subnet1

A virtual machine named VM1 that has the required Windows Server configurations to allow Remote

Desktop connections

NSG-Subnet1 has the default inbound security rules only.

NSG-VM1 has the default inbound security rules and the following custom inbound security rule:

Priority: 100

Source: Any

Source port range: *

Destination: *

Destination port range: 3389

Protocol: UDP

Action: Allow

VM1 connects to Subnet1. NSG1-VM1 is associated to the network interface of VM1. NSG-Subnet1 is associated to Subnet1.

You need to be able to establish Remote Desktop connections from the internet to VM1.

Solution: You add an inbound security rule to NSG-Subnet1 that allows connections from the Any source to the VirtualNetwork destination for port range 3389 and uses the TCP protocol. You remove

NSG-VM1 from the network interface of VM1.

Suggested answer: B

Explanation:

The default port for RDP is TCP port 3389. A rule to permit RDP traffic must be created automatically when you create your VM.

Note on NSG-Subnet1: Azure routes network traffic between all subnets in a virtual network, by default.
