_______________________________________________________________
5.
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

_______________________________________________________________
6.

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
route that is learned through the EIGRP routing protocol
route that is learned through the OSPF routing protocol
static route
_______________________________________________________________
7.

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
routes that are learned through the OSPF routing protocol
a configured default route
a configured static route to the network 209.165.200.224
_______________________________________________________________
8.
What type of IPv6 address is required as a minimum on IPv6 enabled interfaces?
static
global unicast
link-local
loopback
unique local
_______________________________________________________________
9.
What address changes as a packet travels across multiple Layer 3 Ethernet hops to its final destination?
source Layer 2 address
source IP
destination port
destination IP

_______________________________________________________________
10.
Fill in the blank.

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.

11.
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.)
destination MAC address
source ARP table
destination IP address
source IP address
source MAC address
Layer 2 header

_______________________________________________________________
12.
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 MAC address
network number
subnet mask
destination IP address
source MAC address

_______________________________________________________________
13.
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.

_______________________________________________________________
14.
What are two functions of a router? (Choose two.)
It manages the VLAN database.
It increases the size of the broadcast domain.
It controls the flow of data via the use of Layer 2 addresses.
It determines the best path to send packets.
It connects multiple IP networks.

_______________________________________________________________
15.
What is one feature that distinguishes routers from Layer 2 switches?

Routers support a variety of interface types. Switches typically support Ethernet interfaces.
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 can be configured with IP addresses. Switches cannot.

_______________________________________________________________
16.
Which statement describes a route that has been learned dynamically?

It is automatically updated and maintained by routing protocols.
It is unaffected by changes in the topology of the network.
It has an administrative distance of 1.
It is identified by the prefix C in the routing table.

_______________________________________________________________
17.
Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)

The metric is always determined based on hop count.
Administrative distance refers to the trustworthiness of a particular route.
Routes with the smallest metric to a destination indicate the best path.
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.

_______________________________________________________________
18.

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.)

Packets that are destined for the network 2001:DB8:ACAD:2::/64 will be forwarded through Fa0/1.
R1 does not know a route to any remote networks.
The interface Fa0/1 is configured with IPv6 address 2001:DB8:ACAD:A::12.
Packets that are destined for the network 2001:DB8:ACAD:2::54/128 will be forwarded through Fa0/0.
The network FF00::/8 is installed through a static route command.

_______________________________________________________________
19.

Place the options in the following order:
next hop 
destination network 
metric
- not scored -
administrative distance 
route timestamp 
route source protocol 
- not scored -

_______________________________________________________________
20.
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)# ip forward-protocol ?
Router(config)# service ?
Router(config)# ip route ?
Router(config)# router ?
_______________________________________________________________
21.
In order for packets to be sent to a remote destination, what three
pieces of information must be configured on a host? (Choose three.)

IP address
default gateway
subnet mask
hostname
DNS server address
DHCP server address

_______________________________________________________________
22.

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 is a directly connected route.
It indicates that this route has been deleted from the routing table.
It indicates that this route was learned via EIGRP.
It indicates that this is a default route.

_______________________________________________________________
23.

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 File_server1
the MAC address of S2
the MAC address of the G0/0 interface on R2
the MAC address of S1
the MAC address of the G0/0 interface on R1

_______________________________________________________________
24.
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 link-local
ipv6 address ipv6-address/prefix-length
