Chap 4 Routing

What are two functions of a router? (Choose two.)

It determines the best path to send packets.* It connects multiple IP networks.*

Refer to the exhibit. What is the purpose of the highlighted field in the line that is displayed from the show ip route command?

It indicates that this route was learned via EIGRP.*

Which statement describes a route that has been learned dynamically?

It is automatically updated and maintained by routing protocols.*

What two pieces of information are displayed in the output of the show ip interface brief command? (Choose two.)

Layer 1 statuses* IP addresses*

Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. What two conclusions can be drawn from the routing table? (Choose two.)

R1 does not know a route to any remote networks.* The interface Fa0/1 is configured with IPv6 address 2001:DB8:ACAD:A::12.*

A network administrator is implementing dynamic routing protocols for a company. Which command can the administrator issue on a router to display the supported routing protocols?

Router(config)# router ?*

What is one feature that distinguishes routers from Layer 2 switches?

Routers support a variety of interface types. Switches typically support Ethernet interfaces.*

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

Routes with the smallest metric to a destination indicate the best path.* Administrative distance refers to the trustworthiness of a particular route.*

Refer to the exhibit. What will the router do with a packet that has a destination IP address of 192.168.12.227?

Send the packet out the Serial0/0/0 interface.*

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.*

When a computer is pinging another computer for the first time, what type of message does it place on the network to determine the MAC address of the other device?

an ARP request*

In order for packets to be sent to a remote destination, what three pieces of information must be configured on a host? (Choose three.)

default gateway* IP address* subnet mask*

Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. Which two types of routes are displayed in the routing table? (Choose two.)

directly connected network* local host route*

Refer to the exhibit. A network administrator issues the show ip route command on R2. What two types of routes are installed in the routing table? (Choose two.)

directly connected networks* routes that are learned through the EIGRP routing protocol*

Which command is used to configure an IPv6 address on a router interface so that the router will combine a manually specified network prefix with an automatically generated interface identifier?

ipv6 address ipv6-address/prefix-length eui-64*

What type of IPv6 address is required as a minimum on IPv6 enabled interfaces?

link-local*

Refer to the exhibit. A network administrator has configured R1 as shown. When the administrator checks the status of the serial interface, the interface is shown as being administratively down. What additional command must be entered on the serial interface of R1 to bring the interface up?

no shutdown*

A packet moves from a host on one network to a device on a remote network within the same company. If NAT is not performed on the packet, which two items remain unchanged during the transfer of the packet from source to destination? (Choose two.)

source IP address* destination IP address*

What address changes as a packet travels across multiple Layer 3 Ethernet hops to its final destination?

source Layer 2 address*

Which two items are used by a host device when performing an ANDing operation to determine if a destination address is on the same local network? (Choose two.)

subnet mask* destination IP address*

Refer to the exhibit. PC1 attempts to connect to File_server1 and sends an ARP request to obtain a destination MAC address. Which MAC address will PC1 receive in the ARP reply?

the MAC address of the G0/0 interface on R1*

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?

to provide a route to forward packets for which there is no route in the routing table*
