Question 6

(Routing Table) as a data packet arrives at the router, the router looks at its _______ _____ to find out where to forward the ____ ______ along the best path to its destination.

Answer 6

routing, table, data, packet

Question 7

(Routing Table) A basic routing table contains:

Answer 7

final destination

Question 9

(Routing Table) Subnet mask: determines which part of the IP address is the ____ and _______ portion

Answer 9

host, network

Question 10

(Routing Table) Gateway: tells the router which __ _______ the data packet should be ___________ to

Answer 10

IP, address, forwarded

Question 11

(Routing Table) Interface: the outgoing IP address of the _____ that’s sending the ____.

Answer 11

device, data

Question 12

(Routing Table) Next hop: the IP address to which the IP address is __________.

Answer 12

forwarded

Question 13

(Routing Table) Metric: determines the best _____ among multiple ____________.

Answer 13

route, destinations

Question 14

(Routing protocols) Routing protocols collect information about the current ________ ______ and map out the best path for data packets to take to their specific ___________.

Answer 14

network, status, destination

Question 15

there are three different types of routing protocols:

Answer 15

-Distance Vector
-Link State
-Hybrid

Question 16

there are three different types of routing protocols:

Answer 16

-Distance Vector
-Link State
-Hybrid

Question 17

Distance vector: These protocols factor in the distance to the destination based on how many hops. A hop refers to how many routers a data packet has to go through to reach its destination.

Question 18

One of the distance vector protocols is called RIP, which stands for Routing Information Protocol.

Question 19

Routers that use RIP broadcast their routing information to other routers every 30 seconds, regardless if the routing information has changed or not.

Question 20

developers created RIP version 2, which solved the problem of _________ broadcast traffic that RIP version 1 caused.

Answer 20

excessive

Question 21

another distance vector routing protocol is called BGP which stands for ______ _______ ________

Answer 21

border, gateway, protocol

Question 22

(BGP) and this is the standard _______ ________ of the internet, it determines routing directions that are based on paths and policies.

Answer 22

routing, protocol

Question 23

Link state is a routing protocol that is used by routers to share __________ and independently map out the best path on a _______.

Answer 23

information, network

Question 24

Two examples of link state protocols are OSPF (____ ________ ____ _____) and ISIS (__________ ______ __ ___________ ______).

Answer 24

-Open Shortest Path First
-Intermediate System to Intermediate System

Question 25

(OSPF) is used to determine the correct route for ____ ________ to take to their destination.

Answer 25

data, packets

Question 26

(OSPF) It collects information from other routers using __ and creates a topology map of the _______.

Answer 26

IP, network

Question 27

ISIS, organizes routers into _______, meaning that the routers are organized into ______, and this is how ISIS primarily functions within these domains.

Answer 27

domains, groups

Question 28

(ISIS) Unlike OSPF, which uses IP to communicate, ISIS uses CLNS instead, which is a ____________ _______ _______.

Answer 28

Connectionless, network, service

Question 29

(Hybrid) In this case, we're talking about EIGRP (__________ ________ _______ _______ ________).

Answer 29

Enhanced, Interior, Gateway, Routing, Protocol

Question 30

(EIGRP) It is a combination of ________ ______ and ____ _____ protocols and only runs on Cisco routers.

Answer 30

distance, vector, link, state

Question 31

(EIGRP) It is ____, has less overhead, and can support many _______ _____ protocols.

Answer 31

fast, network, layer

Question 32

SIP stands for _______ ________ ________, and this protocol is used for establishing communication sessions over the internet.

Answer 32

Session, Initiation, Protocol

Question 33

(SIP) Voice over IP (VoIP), which is a term used for _____ _______________ over __ ________.

Answer 33

Voice, Communications, IP, networks

Question 34

(SIP) For example, VolP, also uses SIP. It is also used for services such as _______ _________ and ___________.

Answer 34

instant, messaging, conferencing

Question 35

(SIP) SIP operates at the __________ _____ in the OSI model.

Answer 35

application, layer
