Exam 1

PC A is connected to switch S1, which in turn is connected to router R1. Router R1 is connected to a cloud, and the cloud is connected to Server B. At one side of the PC is a label with the following information: PC A MAC address: 00-0B-85-7F-47-00 IPv4 address: 192.168.10.10 At one side of the switch is a label with the following information: S1 MAC address: 00-0B-85-D0-BB-F7 IPv4 address: 192.168.11.1 At one side of the router is a label with the following information: R1 MAC address: 00-0B-85-7F-86-B0 IPv4 address: 192.168.10.1 At one side of the server is a label with the following information: SERVER B MAC address: 00-0B-85-7F-0A-0B IPv4 address: 192.168.12.16 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?

192.168.12.16

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

A router connects multiple IP networks. It determines the best path to send packets.

Administrative distance

When a router receives a packet, what information must be examined in order for the packet to be forwarded to a remote destination?

Destination IP address

10.3.0.0

Destination network

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

IP addresses Layer 1 statuses

Server B is connected to switch S1, which in turn is connected to router R1. Router R1 is connected to a cloud, and the cloud is connected to PC A. At one side of the server is a label with the following information: SERVER B MAC address: 00-0B-85-7F-0A-0B IPv4 address: 192.168.10.16 At one side of the switch is a label with the following information: S1 MAC address: 00-0B-85-D0-BB-F7 IPv4 address: 192.168.11.1 At one side of the router is a label with the following information: R1 MAC address: 00-0B-85-7F-86-B0 IPv4 address: 192.168.10.1 At one side of the PC is a label with the following information: PC A MAC address: 00-0B-85-7F-47-00 IPv4 address: 192.168.12.10 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.

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

It is a logical interface internal to the router.

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.

A network administrator enters the command copy running-config startup-config. Which type of memory will the startup configuration be placed into?

NVRAM

172.16.2.2

Next hop

4 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?

No Shutdown

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.

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

a default static route a static route to a specific network

What route would have the lowest administrative distance?

a directly connected network

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

bandwidth delay

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 subnet mask

21024000

metric

The exhibit shows PC1 assigned an address of 192.168.10.8/24 attached to a switch that is attached to the G0/0 port of R1. R1 has a serial connection to R2 through port S0/0/0 on both routers. Port G0/0 on router R2 connects to a switch that connects to a PC labeled PC2 with the IP address of 192.168.11.5/24. 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?

remove the Ethernet header and configure a new Layer 2 header before sending it out S0/0/0

Which packet-forwarding method does a router use to make switching decisions when it is using a forwarding information base and an adjacency table?

Cisco Express Forwarding

The exhibit contains CLI output that says: R1# show ipv6 route <output omitted> C 2001:DB8:ACAD:2::/64 [0/0] via ::, FastEthernet0/0 L 2001:DB8:ACAD:2::54/128 [0/0] via ::, FastEthernet0/0 C 2001:DB8:ACAD:A::/64 [0/0] via ::, FastEthernet0/1 L 2001:DB8:ACAD:A::12/128 [0/0] via ::, FastEthernet0/1 L FF00::/8 [0/0] via ::, Null0 R1# 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.

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.

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.)

subnet mask destination IP address

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

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

to enable the router as an IPv6 router

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
