Final answer:
The transport mode does not encrypt the header of the packet. The correct answer is B. False.
Step-by-step explanation:
In computer networking, the header of a packet contains important information about the packet, such as the source and destination IP addresses. In transport mode, the packet's header is not encrypted, while the payload (data) is. The transport mode is used in IPsec (Internet Protocol Security), which provides secure communication over an IP network.
For example, in IPsec's transport mode, the IP header remains unencrypted but the payload is encrypted. This allows the packet to reach its destination with the necessary routing information intact, while protecting the confidentiality and integrity of the payload data.
