Chap 4

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

Ip Address, Subnet mask, Default gateway

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? D

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

Consider the following routing table entry for R1: D 10.1.1.0/24 [90/2170112] via 209.165.200.226, 00:00:05, Serial0/0/0 30. What is the significance of the Serial0/0/0?

It is the interface on R1 used to send data that is destined for 10.1.1.0/24.*

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

Layer 1 statuses* IP addresses*

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

Link Local

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.*

What are two common types of static routes in routing tables

a default static route a static route to a specific network

What route would have the lowest administrative distance

a directly connected network

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

Which two network parameters are used by EIGRP as metrics to select the best path to reach a network? (Choose Two.)

bandwidth* Delay

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.)

destination 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

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 is a characteristic of an IPv4 interface on a Cisco IOS router

it is a logical int internal to the router

When a router receives a packet, it examines the destination address of the packet and looks in the "_________"table to determine the best path to use to forward the packet.

routing

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 software is used for a network administrator to make the initial router configuration securely?

terminal emulation client software

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* the connected router

What command will enable a router to begin sending messages that allow it to configure a link-local address without using an IPv6 DHCP server?

the ipv6 unicast-routing command

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*
