Link State Routing - Answer-Dynamic routing method in which routers tell neighboring
routers of their existence through packets called Link State Advertisements (LSAs). By
interpreting the information in these packets, routers can create maps of the entire
network. Maintain complete map. Periodic updates to adjacent
Distance Vector Routing - Answer-Each router passes a copy of its routing table to its
adjacent neighbors. The neighbor adds the route to its own table, incrementing the
metric to reflect the extra distance to the end network. The distance is given as a hop
count; the vector component specifies the address of the next hop. Hop count and
vector. Convergence slows network
Routing Information Protocol (RIP) - Answer-A dynamic protocol that uses distance-
vector routing algorithms to decipher which route to send data packets. 15 hop limit
Open Shortest Path First (OSPF) - Answer-An interior gateway routing protocol
developed for IP networks based on the shortest path first or link-state algorithm. 32 bit
identifier
Path-Vector Routing Protocol - Answer-A protocol that uses dynamically updated paths
or routing tables to transmit packets from one autonomous network to another. Not
scalability issue of distance vector (BGP)
TCP/IP Model Layers - Answer-application, transport, internet, network access
OSI Model Layers - Answer-Application, Presentation, Session, Transport, Network,
Data Link, Physical
Data Link Layer - Answer-The second layer in the OSI model. The Data Link layer
bridges the networking media with the Network layer. Its primary function is to divide the
data it receives from the Network layer into frames that can then be transmitted by the
Physical layer. Sub layers are LLC and MAC
