CompTIA Security+ Exam Prep

Answer: A - End-to-end encryption enables attackers to learn about a captured packet and where it is headed. This is because the headers, addresses, routing, and trailer information are not encrypted. However, advantages include more flexibility to the user, higher granularity of functionality, and the network does not need to have a key to decrypt each packet. With end-to-end encryption, the packets do not need to be decrypted and then encrypted again at each hop because the headers and trailers are not encrypted. The devices in between the origin and destination just read the necessary routing information and pass the packets on their way. The encryption is usually initiated by the user of the originating computer.
