Module 7 Routing between network

Question 1

What information in the IP packet does the router use to determine which interface to forward the packet?

Answer 1

Destination IP address

Question 2

A default route is the interface through which the router forwards:

Answer 2

A Packet containing a destination IP network address that is not in the routing table of the router

Question 2

True or false? If Host-A has an IP packet to send to Host-B, and Host-A has determined that Host-B is on a different network. Host-A will encapsulate the IP packet in an Ethernet frame with the destination MAC address of the its default gateway.

Answer 2

True

Question 3

A host will send a packet to the default gateway when:

Answer 3

The destination IP address is on a different network

Question 4

Which information is used by routers to forward a data packet toward its destination?

Answer 4

Destination IP address

Question 5

A router receives a packet from the Gigabit 0/0 interface and determines that the packet needs to be forwarded out the Gigabit 0/1 interface. What will the router do next?

Answer 5

Create a new Layer 2 Ethernet frame to be sent to the destination

Question 6

During the process of forwarding traffic, what will the router do immediately after matching the destination IP address to a network on a directly connected routing table entry?

Answer 6

switch the packet to the directly connected interface

Question 7

What will a router do if it cannot determine where to forward an incoming packet?

Answer 7

The router will drop it

Question 8

In implementing a LAN in a corporation, what are three advantages of dividing hosts between multiple networks connected by a distribution layer? (Choose three.)

Answer 8

1- it provide increase security
2- it splits up broadcast domain and decreased traffic
3- It makes the host invincible to those on other local network segments

Question 9

What type of route is indicated by the code C in an IPv4 routing table on a Cisco router?

Answer 9

Directly connected route

Question 10

Which portion of the network layer address does a router use to forward packets?

Answer 10

Network portion

Question 11

What role does a router play on a network?

Answer 11

Selecting the path to destination networks

Question 12

A router receives an incoming packet and determines that the destination host is located on a LAN directly attached to one of the router interfaces. Which destination address will the router use to encapsulate the Ethernet frame when forwarding the packet?

Answer 12

MAC address of the destination host

Question 13

Which address should be configured as the default gateway address of a client device?

Answer 13

The IPV4 address of the router interface that is connected to the same LAN
