Network test of doom

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

• source data-link address

• source IP address

• destination IP address

• destination data-link 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?

• route the packet out of the gigabit 0/1 interface

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

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

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

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

• R1: G0/0

• R1: S0/0/0

• R2: S0/0/0

• R2: S0/0/1

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?

• analyze the destination IP address

• look up the next-hop address for the packet

• switch the packet to the directly connected interface

• discard the traffic after consulting the route table

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 save it in the sending queue and try to forward it again later.

• The router will drop it

• The router will forward it out to all interfaces.

In implementing a LAN in a corporation, what is an advantage of dividing hosts between multiple networks connected by a distribution layer?

• It increases traffic bandwidth between segments through distribution layer devices.

• Only LAN switches are needed.

• It splits up broadcast domains and decreases traffic

• It reduces complexity and expense by using LAN switch devices.

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

• default route

• static route

• directly connected route

• dynamic route that is learned through EIGRP

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

• gateway address

• broadcast address

• host portion

• network portion

What role does a router play on a network?

• connecting smaller networks into a single broadcast domain

• forwarding frames based on a MAC address

• selecting the path to destination networks

• 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 SVI on the switch

• MAC address of the interface of the connected router

• MAC address of the default gateway of the LAN

• MAC address of the destination host
