Final answer:
The assertion that inbound data traffic from an on-premises network to Azure via ExpressRoute is always free is false. High-voltage power lines are not insulated but held aloft by insulating connectors, making that statement false too. Lastly, the Middle Passage was not part of the Indian Ocean trade network but the Atlantic slave trade, which is also false.
Step-by-step explanation:
The statement regarding Azure ExpressRoute connection that inbound data traffic from an on-premises network to Azure is always free is false. While ExpressRoute provides a private connection between an on-premises network and Azure data centers, the billing for data transfer is not unilateral. Inbound data transfer to Azure is typically free, but this can vary depending on the specific services used or if there's an exceptionally large amount of data being transferred which could potentially incur a cost.
As for high-voltage power lines, the statement is false. These wires are not covered in insulating material; they are bare and are held aloft by insulators that prevent the current from grounding. Insulating connectors or insulators are designed to withstand the high voltage and prevent energy loss.
Regarding the Middle Passage, the statement that it was a part of the Indian Ocean trade network is false. The Middle Passage refers to the part of the Atlantic slave trade where enslaved Africans were transported across the Atlantic Ocean to the Americas.
