7. Question

1 points

The exhibit consists of a network diagram that shows R1 with three network connections: two Ethernet segments and a WAN link. The WAN link connects R1 to a second router R2. R2 is the DCE on the WAN link. The configuration shown is as follows:

R1(config)# interface serial 0/0/0
R1(config-if)# description Link to R2
R1(config-if)# ip address 209.165.200.225 255.255.255.252
R1(config-if)# exit
R1(config)#

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 enable
clockrate 128000
end
no shutdown

8. Question

1 points

What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?

The no shutdown command is required to place this interface in an UP state
It is a logical interface internal to the router
Only one loopback interface can be enabled on a router
It is assigned to a physical port and can be connected to other devices

9. Question

1 points

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

IP addresses
MAC addresses
Layer 1 statuses
next-hop addresses
interface descriptions

10. Question

1 points

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
destination MAC address
source MAC address
subnet mask
network number

11. Question

1 points

Refer to the exhibit. PC A sends a request to Server B. What IPv4 address is used in the destination field in the packet as the packet leaves PC A?

192.168.10.10
192.168.11.1
192.168.10.1
192.168.12.16

12. Question

1 points

Refer to the exhibit. What does R1 use as the MAC address of the destination when constructing the frame that will go from R1 to Server B?

If the destination MAC address that corresponds to the IPv4 address is not in the ARP cache, R1 sends an ARP request
The packet is encapsulated into a PPP frame, and R1 adds the PPP destination address to the frame
R1 uses the destination MAC address of S1
R1 leaves the field blank and forwards the data to the PC

13. Question

1 points

Refer to the exhibit. 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
open the header and use it to determine whether the data is to be sent out S0/0/0

14. Question

1 points

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 GigabitEthernet0/0 interface
Send the packet out the GigabitEthernet0/1 interface

15. Question

1 points

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

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

16. Question

1 points

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

hop count
bandwidth
jitter
resiliency
delay
confidentiality

17. Question

1 points

What route would have the lowest administrative distance?

a directly connected network
a static route
a route received through the EIGRP routing protocol
a route received through the OSPF routing protocol

18. Question

1 points

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

Administrative distance refers to the trustworthiness of a particular route
A router first installs routes with higher administrative distances
The value of the administrative distance cannot 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
The metric varies depending on which Layer 3 protocol is being routed

19. Question

1 points

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 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
It is the R1 interface through which the EIGRP update was learned.
It is the interface on the final destination router that is directly connected to the 10.1.1.0/24 network.
It is the interface on the next-hop router when the destination IP address is on the 10.1.1.0/24 network.

20. Question

1 points

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 network FF00::/8 is installed through a static route command
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::/64 will be forwarded through Fa0/1
Packets that are destined for the network 2001:DB8:ACAD:2::54/128 will be forwarded through Fa0/0

21. Question

1 points

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
The configuration needs to be saved first.
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.

22. Question

1 points

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 forward all packets 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 packets destined for the network 0.0.0.0 to the device with IP address 209.165.200.226
to provide a route to forward packets for which there is no route in the routing table

23. Question

1 points

What are two common types of static routes in routing tables? (Choose two)

a default static route
a built-in static route by IOS
a static route to a specific network
a static route shared between two neighboring routers
a static route converted from a route that is learned through a dynamic routing protocol

24. Question

1 points

What is the effect of configuring the ipv6 unicast-routing command on a router?

to assign the router to the all-nodes multicast group
to enable the router as an IPv6 router
to permit only unicast packets on the router
to prevent the router from joining the all-routers multicast group

25. Question
