Final answer:
False. Inbound data traffic from an on-premises network to Azure using Azure ExpressRoute connection is not always free. There are costs associated with this service, including data transfer fees for inbound traffic.
Step-by-step explanation:
False. When using an Azure ExpressRoute connection, inbound data traffic from an on-premises network to Azure is not always free. ExpressRoute is a service provided by Microsoft that allows organizations to establish a private and dedicated network connection between their on-premises network and Azure. However, there are costs associated with this service, including data transfer fees for inbound traffic.
For example, if you have an ExpressRoute circuit with 100 GB of data traffic per month, and you are sending 50 GB of data from your on-premises network to Azure, you will be charged for the 50 GB of inbound data transfer.
