Networking Essentials - Unti 7 Test

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

• source IP address

• source data-link address

• destination data-link address

• destination IP address

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?

• look into the routing table to determine if the destination network is in the routing table

• route the packet out the Gigabit 0/1 interface

• create a new Layer 2 Ethernet frame to be sent to the destination

• look into the ARP cache to determine the destination IP address

Refer to the image. The IP address of which device interface should be used as the default gateway setting of host H1?

• R1: S0/0/0

• R2: S0/0/1

• R1: G0/0

• R2: S0/0/0

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?

• switch the packet to the directly connected interface

• discard the traffic after consulting the route table

• analyze the destination IP address

• look up the next-hop address for the packet

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

• The router will send an incident message to the network administrator

• The router will forward it out all interfaces

• The router will save it in the sending queue and try to forward it again later

• The router will drop it

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

• It splits up broadcast domains and decreases traffic

• It makes the hosts invisible to those on other local network segments

• It reduces complexity and expense by using LAN switch devices

• It increases traffic bandwidth between segments through distribution layer devices

• It provides increased security

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

• default route

• static route

• dynamic route that is learned through EIGRP

• directly connected route

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

• host portion

• network portion

• broadcast address

• gateway address

What role does a router play on a network?

• connecting smaller networks into a single broadcast domain

• selecting the path to destination networks

• forwarding frames based on a MAC address

• forwarding Layer 2 broadcasts

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?

• MAC address of the destination host

• MAC address of the SVI on the switch

• MAC address of the interface of the connected router

• MAC address of the default gateway of the LAN
