Select correct alternatives: O QUIC is an old protocol designed in the 80's as an alternative to UDP and TCP. O QUIC belongs to the transport layer in the Internet five-layer protocol stack. O QUIC needs maximum 1 handshake phase to establish a secure connection. O QUIC is a relative new protocol originally designed by Google. O QUIC has algorithms for network congestion control and for handling packet loss. O QUIC belongs to the application layer in the Internet five-layer protocol stack. O QUIC uses a specified fixed encryption suite and needs no handshake phase to set up a connection. O QUIC uses UDP as transport protocol. O QUIC leaves network congestion control and reliable data transport to the application using QUIC. O QUIC uses TCP as transport protocol.

Two transport-layer protocols offer services that certain applications may make use of (UDP or TCP). So, when a packet arrives at its destination, how can a computer tell which transport layer is involved?

True or false 6. Before sending a data packet into a packet-switching network, the source must determine all of the links that the packet will traverse between source and destination. 7. With non-persistent connections between a web browser and a web server, it is possible for a single TCP segment to carry two distinct HTTP request messages.

Consider connectionless protocols as a potential replacement for connection-based protocols, and assess their advantages and disadvantages.
