Microsoft Azure Administrator Associate AZ-104 Practice Question

To enable web traffic on port 80, you need to add an inbound security rule to the Network Security Group (NSG) associated with the virtual machine's network interface or subnet. NSGs act as virtual firewalls that control inbound and outbound traffic to network interfaces or subnets. By adding a rule that allows inbound traffic on port 80, you permit HTTP requests to reach the virtual machine. Modifying the virtual machine's properties will not affect network traffic rules. Adjusting the routing table controls the direction of traffic but does not allow or deny traffic on specific ports. Setting up a load balancer is unnecessary unless you are managing traffic to multiple virtual machines.
