transmission of data
-
reassembly of packets
-
filtering of packets
-
segmentation of packets
-
All of the above

-
UDP
-
RIP
-
Dijkstra
-
OSPF
B
Correct answer
Explanation
Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Routing Information Protocol (RIP) and Dijkstra are routing protocols, while User Datagram Protocol (UDP) is an internet protocol.
