Q

What layer is DHCP and what does it do?

A

Layer 3 network

Gets the hosts IP address from the DHCP server

18
Q

How does DHCP work?

A 
Discover 
-host sends request for DHCP sequence 
Offer
-DHCP offers a ip 
Request
-host requests to use ip 
Acknowledge 
-DHCP affirms the lease
19
Q

What is routing used for?

A

To reach hosts on other networks

20
Q

What is NAT

A

Network address translation

Conserves IPv4 addresses

21
Q

What is RIP and OSPF

A

A routing protocol used to exchange info about networks to calculate the best path

22
Q

How does RIP work

A

Uses distance vectors
(Routers only know what there neibors tell them)

Sends all RIP routes every 30 sec

Based on metric hop count

23
Q

How does OSPF work

A 
Open shortest path first 
LinkState 
-all info sent to all routers 
-all routers have a complete map
Based on areas 
Based on link speed
24
Q

OSPF neighbors

A

OSPF routers send a hello every 10 sec. if no reply after 40 sec neighbor is dead

25
Q

How long is a IPV6 address?

A

128
64 host
64 net

26
Q

Link local unicast address

A

FE08::/10

27
Q

IPv6 global unicast structure

A

(x) x.x.x.x

Global routing prefix
Subnet
Interface ID

28
Q

What does the transport layer do?

A

Responsible for delivery of segments.

Uses ports

29
Q

What’s the point of point #

A

Port # used by TCP and UDP TO tell the difference between applications

30
Q

Characteristics of TCP

A

Provides reliable delivery
Stageful
Segments and reassembles data segments.
Flow control

Layer 4

31
Q

How does TCP reliable

A

Each byte is given a sequence # uses to reassemble

Destination replay with the ACK to acknowledge right amount

32
Q

TCP header fields

A

Port #
Sequence #
Acknowledgement #
Window size

33
Q

Explain the TCP 3 way handshake

A

Computer A sends a syn1

Comp two returns an ack of 2 and a syn of 1 comp A returns a syn and ack of 2

34
Q

What is tcp window size

A

TCP uses window size to manage data

35
Q

What is UDP

A

It is a connection protocol that is faster then TCP and cheaper but lacks many of the features TCP has
Layer 4

36
Q

What port is HTTP

A

80

37
Q

What is FTP and what layer is it on?

Used to send it copy files from a server

Port 20-21

38
Q

What is telnet?

A

Commands and data sent as plain text

39
Q

What is SSH

A

Commands and data are encrypted

40
Q

Email its ports and its protocols

A

SMTP 25

POP3 110

IMAP143

41
Q

What layer is DNS and what does it do?
