8. Question

8
Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)

The metric varies depending which Layer 3 protocol is being routed, such as IP.
A router first installs routes with higher administrative distances.
The value of the administrative distance can not be altered by the network administrator.
Routes with the smallest metric to a destination indicate the best path.
Administrative distance refers to the trustworthiness of a particular route.
The metric is always determined based on hop count.

12. Question

12
A network administrator configures the interface fa0/0 on the router R1 with the command ip address 172.16.1.254 255.255.255.0. However, when the administrator issues the command show ip route, the routing table does not show the directly connected network. What is the possible cause of the problem?

The interface fa0/0 has not been activated.
No packets with a destination network of 172.16.1.0 have been sent to R1.
The subnet mask is incorrect for the IPv4 address.
The configuration needs to be saved first.

ipv6 address ipv6-address/prefix-length link-local
ipv6 address ipv6-address/prefix-length

Fill in the blank.

When a router receives a packet, it examines the destination address of the packet and looks in the (routing, ROUTING) table to determine the best path to use to forward the packet.

15. Question

15
A network administrator configures a router by the command ip route 0.0.0.0 0.0.0.0 209.165.200.226. What is the purpose of this command?

If PC1 is sending a packet to PC2 and routing has been configured between the two routers, what will R1 do with the Ethernet frame header attached by PC1?

nothing, because the router has a route to the destination network
remove the Ethernet header and configure a new Layer 2 header before sending it out S0/0/0
open the header and replace the destination MAC address with a new one
