Q$1.[/4$ points$]$: choose the best answer.

The IPvo packet contains

wajk yideta iasan

G$)$U

a$)32$ bit addresses

b$)64$ bit addresses

c$)128$ bit address

d$)$ Variable

A network point that provides entrance into another network is called:

a$)$ Node

b$)$ Gateway

c$)$ Switch

d$)$ Router

is not a multiple access protocol.

a$)$ ALOHA

b$)$ PPP

c$)$ CSMA

d$)$ TDMA

Which random access protocol listens before transmitting?

a$)$ CSMA

b$)$ ALOHA

c$)$ Slotted ALOHA

d$)$ None of the above

In CSMA, the collision can still occur because of:

a$)$ Processing delay

b$)$ Queuing delay

c$)$ Propagation delay

d$)$ None of the above

If you have the following efficiency equation for the CSMA: efficiency $=\frac{1}{1+5\frac{t_{\text{p}\text{o}\text{p}}}{t}}$ Then, we have better efficiency as:

a$)$ throp goes to $0$

b$)$ timn goes to infinity

c$)$ trans goes to $0$

d$)$ both a and $b$

If you have an IP packet of size $3630$ bytes, to how many fragments could this packet be fragmented if the MTU size is $500$ bytes?

a$)5$

b$)6$

c$)7$

d$)8$

$2$
