a router is a network device that forwards traffic depending on the destination address of that traffic

Answer 1

basic definition of a router

Question 2

In which layer of the TCP/IP address model is the routher?

Answer 2

the Network Layer

Question 3

In a routing table, what is the column containing a row for each known network called?

Answer 3

Destination Network Column

Question 4

What two things are in the destination network column of a routing table?

Answer 4

the network ID and network mask

Question 5

???

Answer 5

Catchall Address

Question 6

The number of times a package passes through a different router before reaching its destination is called…

Answer 6

Total Hops

Question 7

What is the public router interface called?

Answer 7

The WAN Interface

Question 8

What is the private router interface called?

Answer 8

The LAN interface

Question 9

ACRONYM:

WAN

Answer 9

Wide Area Network

Question 10

ACRONYM:

DHCP

Answer 10

Dynamic Host Configuration Protocol

Question 11

What is the name of the protocol used when a computer is assigned an IP address from the router?

Answer 11

Dynamic Host Configuration Protocol

Question 12

What do routers follow in order to speak to each other and share routing information?

Answer 12

Routing Protocols

Question 13

Which protocol does a router use to share information within a single, autonomous system?

Answer 13

Interior Gateway Protocols

Question 14

What is the term for a collection of networks that are all under the control of the same network operator?

Answer 14

An autonomous system

Question 15

What are the two main types of interior gateway protocols?

Answer 15

Link state routing protocols and distance-vector protocols

Question 16

What is a computer science term meaning list?

Answer 16

a Vector

Question 17

This interior gateway protocol is older and consists of routers sharing lists of all of the networks they know and how many hops it takes to get to each network

Answer 17

Distance-vector protocol (basically, when a router sends a list, or vector, of the distance of networks)

Question 18

Using this interior gateway protocol, each router advertises the state of the connection of each of its interfaces and runs algorithms to find the best path to a destination at a particular moment.

Answer 18

Link state routing protocol

Question 19

ACRONYM:

IANA

Answer 19

Internet Assigned Numbers Authority

Question 20

This type of routing protocol communicates data between routers representing the edge of an autonomous system

Answer 20

Exterior gateway protocol

Question 21

ACRONYM:

ASN

Answer 21

Autonomous System Number Allocation

Question 22

This non-profit organization manages IP address allocation and ASNs

Answer 22

Internet Assigned Numbers Authority

Question 23

What kind of router connects with a core internet router?

Answer 23

An edge router

Question 24

How many bits is an ASN?

Answer 24

32 bits

Question 25

How many bits are in an IP address?

Answer 25

32 bits

Question 26

ACRONYM: OSPF

Answer 26

Open Shortest Path First

Question 27

What is the name of the most common link state protocol?

Answer 27

Open Shortest Path First

Question 28

ACRONYM: RIP

Answer 28

Routing Information Protocol

Question 29

What kind of a routing protocol is RIP?

Answer 29

Distance Vector Protocol

Question 30

ACRONYM: EIGRP

Answer 30

Enhanced Interior Gateway Routing Protocol

Question 31

What kind of routing protocol is RIP?

Answer 31

Distance Vector Protocol

Question 32

What is the only exterior gateway protocol in use today?

Answer 32

Border Gateway Protocol (BGP)

Question 33

ACRONYM: BGP

Answer 33

Border Gateway Protocol

Question 34

What is is the network of physical objects embedded with electronics, software, sensors, actuators, and connectivity to enable objects to exchange data with the manufacturer, operator and/or other connected devices>

Answer 34

The Internet of Things

Question 35

Between EIGRP and RIP, which is generally more preferred?

Answer 35

EIGRP

Question 36

Why is EIGRP faster than other distance vector protocols?

Answer 36

It sends incremental updates which reduces the workload and amount of data transferred between routers.

Question 37

What is the term for when routers update their tables is the network topology changes?

Answer 37

Dynamic Routing

Question 38

What does link state routing protocol offer that distance vector protocol does not?

Answer 38

Information on the status of a route; distance vector protocol only knows the shortest route in terms of hops but not if that route is optimally functioning

Question 39

ACRONYM: RFC

Answer 39

Request for Comments

Question 40

What what was established in RFC 1918?

Answer 40

Non-routable address space

Answer 41

the primary 3 ranges of non-routable address space

Question 42

ACRONYM: IETF

Answer 42

Internet Engineering Task Force

Question 43

This open community develops and maintains the standards required for the internet to continue to operate

Answer 43

the Internet Engineering Task Force (IETF)

Question 44

This is a range of IP addresses that cannot be routed to from an outside network

Answer 44
