Explain why the data link layer is tightly coupled with the physical layer.
Describe a physical layer medium that cannot be adequately managed by
the IEEE 802.3 MAC.
In a lab environment, configure a network with a switch and three hosts: A,
B, and C. Set host A to continually send ICMP echo (ping) requests to host
B. Using host C, generate many different forged ARP packets.
Does the switch regress to hub mode? Describe a method for detecting
the regression.
Determine the size of the switch’s internal ARP table. Estimate the
ARP table’s timeout value.
Why is the sequence of pings between hosts A and B required? Does
the A to B traffic need to be ICMP?
