Explanation / Answer

25. (d)

Router works at network layer. So router can analyze a packet upto network layer and hence can get ip address

26.(a)

Switch works at data link layer and hence can filter fragments since fragments are done at network layer.

27 (b)

Switch diverts the fragment to the required destination using switching table thus ensures fragment goes to specific output line.

28(d) default loopback ipv4 address is 127.0.0.1
