In a scenario where you are deploying multiple Azure virtual machines and require the ability to manage and restrict the inbound and outbound network traffic to these VMs from the Internet, which Azure service would you utilize to effectively control access through specific ports?
Explanation:
The correct answer is A. A network security group (NSG) is used to control network traffic to and from Azure resources in an Azure virtual network. It contains security rules that allow or deny inbound and outbound traffic. You can attach an NSG to a virtual network, individual subnets, or even network interfaces assigned to virtual machines. This enables you to manage access to your VMs by controlling the ports through which devices on the Internet can connect.
