A router determines the best path between source and destination for sending data using:
-
A.
IP addresses
-
B.
MAC addresses
-
C.
port numbers
-
D.
data packets
Correct Answer:
A. IP addresses
Explanation:
A router operates at the network layer of the OSI model and utilizes IP addresses to determine the most efficient path for data to travel from its source to its destination. By examining the destination IP address within each incoming data packet, the router consults its routing table to identify the best next-hop or network interface to forward the information toward its final target. Unlike MAC addresses, which are used for local communication within a single network, IP addresses enable routing across different interconnected networks.
