Solution:

Classless Inter-domain Routing (CIDR) receives a packet with address 131.23.151.76. The router's routing table has the following entries:

`Prefix Output Interface Identifier 131.16.0.0/12 3 131.28.0.0/14 5 131.19.0.0/16 2 131.22.0.0/15 1`

The identifier of the output interface on which this packet will be forwarded is ____.

1

2

3

4

5

Solution:

Which of the following assertions about the Internet Protocol (IP) is FALSE?

1

It is possible for a computer to have multiple IP addresses

2

IP packets from the same source to the same destination can take different routes in the network

3

IP ensures that a packet is discarded if it is unable to reach its destination within a given number of hops

4

The packet source cannot set the route of an outgoing packets; the route is determined only by the routing tables in the routers on the way
