A router connects multiple IP networks.*

It controls the flow of data via the use of Layer 2 addresses.

It determines the best path to send packets.*

It provides segmentation at Layer 2.

It builds a routing table based on ARP requests.

hostname

IP address*

subnet mask*

default gateway*

DNS server address

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. 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. Refer to the exhibit.

CCNA 2 v6.0 RSE Chapter 1 Exam Answers q14

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. 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 IP.

16. 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. 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. 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. 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. 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. 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. 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. 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. 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. Refer to the exhibit.
