Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A	TCP, but not UDP
B	TCP and UDP
C	UDP, but not TCP
D	Neither TCP nor UDP

Explanation:

Detailed explanation-1: -Routing packets form source to destination done by network layer and depends on routing algorithm so there is no interface of TCP and UDP at network layer.

Detailed explanation-2: -Stream Control Transmission Protocol (SCTP): This transport layer protocol combines some aspects of UDP and TCP. SCTP provides reliability similar to TCP but maintains a separation between data transmissions (called “chunks”) similar to datagrams in UDP.

Detailed explanation-3: -UDP and TCP are the two Transport Layer protocols used in TCP/IP networks. Both protocols run on top of IP, which is an unreliable system. TCP itself is a reliable protocol, while UDP is an unreliable protocol. Port numbers are needed for data to be sent to the appropriate final destination.

Detailed explanation-4: -False, In contrast to TCP, UDP does not require checksum calculation. UDP does not provide any error or flow control.
