IP Routing (Lesson 1)

Question 1

is an umbrella term for the set of protocols that determine the path that data follows in order to travel across multiple networks from its source to its destination.

Answer 1

IP Routing

Question 2

NAT stands for…?

Answer 2

Network Address Translation

Question 3

It’s a way to map multiple private addresses inside a local network to a public IP address before transferring the information onto the internet.

Answer 3

NAT Network Address Translation

Question 4

NAT Types (5)

Answer 4

• Static NAT
• Dynamic NAT
• Port Address Translation (PAT)
• Routing Information Protocol (RIP)
• Interior Gateway Routing Protocol (IGRP)

Question 5

When the local address is converted to a public one, this NAT chooses the same one.
A consistent public IP address associated with that router or NAT device.

Answer 5

Static NAT

Question 5

Instead of choosing the same IP address every time, this NAT goes through a pool of public IP addresses.
Getting a different address each time the router translates the local address to a public address.

Answer 5

Dynamic NAT

Question 6

It’s a type of dynamic NAT, but it bands several local IP addresses to a singular public one.

Answer 6

Port Address Network (PAT)

Question 7

is a distance-vector routing protocol.
Routers running the distance-vector protocol send all or a portion of their routing tables in routing-update messages to their neighbors.

Answer 7

Routing Information Protocol (RIP)

Question 8

isa distance vector interior gateway protocol developed by Cisco.
It is used by routers to exchange routing data within an autonomous system.

Answer 8

Interior Gateway Routing Protocol (IGRP)

Question 9

____ is short for Francisco.

Answer 9

Cisco

Question 10

____ and ____ Founded the Cisco Company

Answer 10

Leonard Bosack and Sandy Lerner

founded in 1984

Question 11

Features of RIP (4)
(Possible Question? idk)

Answer 11

1. Updates of the network are exchanged periodically.
2. Updates are always broadcasting
3. Full routing tables are sent in updates.
4. Routers always trust routing information received from neighbor routers.

Answer 20

exit

Question 21

This command is used to exit configuration mode and return to privileged mode.

Answer 21

end

Question 22

This command is used to display the current configuration of the router.

Answer 22

Question 23

This command is used to display information about all of the interfaces on the router, including their status, IP address, and bandwidth usage.

Answer 23

Question 24

This command is used to display the routing table of the router, which shows the paths that packets take to reach their destination.

Answer 24

Question 25

This command is used to test the connectivity between the router and a specific IP address.

Answer 25
