Question

Accepted Answer

APIPA is a self-configured IP address used when DHCP server is not available. Router connects multiple networks while switch connects devices within a network.

APIPA stands for Automatic Private IP Addressing
APIPA assigns IP addresses in the range of 169.254.0.1 to 169.254.255.254
Router connects multiple networks and routes data between them
Switch connects devices within a network and forwards data between them
Router operates at the network layer of the OSI model while switch operates at the data link layer
Router uses IP addresses to forward data while switch uses MAC addresses
Example of router: Cisco ISR 4000 series
Example of switch: Cisco Catalyst 2960 series
