Final answer:
It is false that outbound data traffic from Azure to an on-premises network is always free; Azure charges for outbound data, which is known as data egress.
Step-by-step explanation:
The statement that outbound data traffic from Azure to an on-premises network is always free is False. Azure does not charge for inbound data transfer, i.e., data incoming to Azure services, but it does charge for outbound data traffic, which is data going out of Azure services to an external destination, such as an on-premises network. This is also known as data egress, and the cost is determined by various factors like the amount of data traffic being sent and the geographical region it is being sent from.
