Explanation:
The correct answer is D. When deploying virtual machines with identical security rules, you only need one Network Security Group (NSG). An NSG can be associated with multiple subnets and network interfaces, allowing for the same set of inbound and outbound security rules to be applied across all VMs in the subnet. This minimizes the number of security groups required while maintaining consistent security settings.
With an Azure AD subscription, how many security groups are minimally required to deploy five VMs in a virtual network subnet, each with identical public and private IP addresses and identical inbound/outbound security rules?
