Exam Preparation Quiz

Explanations for each answer:

• One network security group (NSG) is incorrect. While NSGs can filter network traffic, they are commonly deployed for individual virtual networks, subnets, or network interfaces. Using a single NSG would not efficiently manage traffic across multiple virtual networks.
• 10 virtual network gateways is incorrect. Virtual network gateways are primarily used for connecting virtual networks to on-premises networks or other virtual networks. They are not designed for controlling inbound traffic across multiple virtual networks.
• 10 Azure ExpressRoute circuits is incorrect. Azure ExpressRoute provides private connectivity between Azure datacenters and on-premises infrastructure. It is not designed for controlling inbound traffic to virtual networks.
• One Azure Firewall is correct
