CCNA 2 v5 Routing Protocols Chapter  1

1

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

destination port
destination IP
source IP
source Layer 2 address*

2
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*
static route
route that is learned through the EIGRP routing protocol

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

routes that are learned through the OSPF routing protocol
a configured static route to the network 209.165.200.224
directly connected networks*
routes that are learned through the EIGRP routing protocol
a configured default route

4
Which two statements correctly describe the concepts of administrative distance and metric?

A router first installs 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
The metric is always determined based on hop count.
Administrative distance refers to the trustworthiness of a particular route.*
The metric varies depending which Layer 3 protocol is being routed, such as IP.

5
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 subnet mask is incorrect for the IPv4 address
No packets with a destination network of 172.16.1.0 have been sent to R1.
The configuration needs to be saved first.
The interface fa0/0 has not been activated.*

6
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 ?*
Router(config)# ip route ?
Router(config)# service ?
Router(config)# ip forward-protocol ?

7
What are the two functions of a router? (Choose two.)

It manages the VLAN database.
It increases the size of the broadcast domain.
It determines the best path to send packets.*
It controls the flow of data via the use of Layer 2 addresses.
It connects multiple IP networks*

8
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*
It indicates that this is a default route.
It indicates that this is a directly connected route.
It indicates that the route has been deleted from the routing table

9
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*
to forward packets destined for the network 0.0.0.0 to the device with IP address 209.165.200.226
to add a dynamic route for the destination network 0.0.0.0 to the routing table
to forward all packets to the device with IP address 209.165.200.226

10
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 identified?

ipv6 address ipv6-address/prefix-length link-local
ipv6 enable
ipv6 address ipv6-address/prefix-length eui-64*
ipv6 address ipv6-address/prefix-length

11
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.)

source MAC address
destination MAC address
subnet mask*
destination IP address*
network number

12
Refer to the exhibit. Match the description with the routing table entries. (Not all options are used.)

route source protocol = D(which is EIGRP)
destination network = 10.3.0.0
metric=21024000
administrative distance = 1
next hop = 172.16.2.2
route timestamp 00:22:15

13
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 R2
the MAC address on File_server1
the MAC address of the G0/0 interface on R1*

14
What type of IPv6 address is required as a minimum on IPv6 enabled interfaces?

global unicast
loopback
link-local*
static
unique local

15
What two pieces of information are displayed in the output of the show ip interface brief command? (Choose two.)

interface descriptions
next-hop address
IP addresses*
Layer 1 statuses*
MAC addresses
speed and duplex settings

16
Which statement describes a route that has been learned dynamically?
It is identified by the prefix C in the routing table.
It is unaffected by changes in the topology of the network.
It has an administrative distance of 1.
It is automatically updated and maintained by routing protocols.*

17
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?

IPv6 enabled
end
clockrate 128000
no shutdown*

18
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 MAC address
destination IP address*
source IP address*
source ARP table
destination MAC address
Layer 2 header

19
Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. What two conclusion can be drawn from the routing table? (Choose two.)

The interface Fa0/1 is configured with IPv6 address 2001:DB8:ACAD:A:12*
The network FF:00::/8 is installed through a static route command.
R1 does not show a route to any remote netowrks.
Packets that are destined for the network 2001:DB8:ACAD:2::54/128 will be forwarded through Fa0/0

20
Refer to the exhibit. What will the router do with a packet that has a destination IP address of 192.168.12.227?

Drop the packet
Send the packet out the Serial0/0/0 interface*
Send the packet out the GigabitEthernet0/1 interface
Send the packet out the GigabitEthernet0/0 interface

21
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 ICMP ping
an ARP request*
a multicast to any Layer 3 devices that are connected to the local network
an RFI (Request for Information) message

22
What is one feature that distinguishes routers from Layer 2 switches?

Switches use tables of information to determine how to process data traffic. Routers do not.
Switches move packets from one physical interface to another. Routers do not.
Routers support a variety of interface types. Switches typically support Ethernet interfaces.*
Routers can be configured with IP addresses. Switches cannot.

23

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*
DNS server address
hostname
subnet mask*
DHCP server address

24

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