New Cisco 200-125 Exam Dumps Collection (Question 5 - Question 14)

Question No: 5

Refer to the exhibit.

Which two statements are true of the interfaces on Switch1? (Choose two.)

A. Multiple devices are connected directly to FastEthernet0/1.

B. A hub is connected directly to FastEthernet0/5.

C. FastEthernet0/1 is connected to a host with multiple network interface cards.

D. FastEthernet0/5 has statically assigned MAC addresses.

E. FastEthernet0/1 is configured as a trunk link.

F. Interface FastEthernet0/2 has been disabled.

Answer: B,E

Explanation:

Carefully observe the information given after command show. Fa0/1 is connected to Switch2, seven MAC addresses correspond to Fa0/1, and these MAC are in different VLAN. From this we know that Fa0/1 is the trunk interface.

From the information given by show cdp neighbors we find that there is no Fa0/5 in CDP neighbor. However, F0/5 corresponds to two MAC addresses in the same VLAN. Thus we know that Fa0/5 is connected to a Hub.

Based on the output shown, there are multiple MAC addresses from different VLANs attached to the FastEthernet 0/1 interface. Only trunks are able to pass information from devices in multiple VLANs.

Question No: 6

Refer to the exhibit.

Given the output shown from this Cisco Catalyst 2950, what is the reason that interface FastEthernet 0/10 is not the root port for VLAN 2?

A. This switch has more than one interface connected to the root network segment in VLAN 2.

B. This switch is running RSTP while the elected designated switch is running 802.1d Spanning Tree.

C. This switch interface has a higher path cost to the root bridge than another in the topology.

D. This switch has a lower bridge ID for VLAN 2 than the elected designated switch.

Answer: C

Explanation:

Since the port is in the blocked status, we must assume that there is a shorter path to the root bridge elsewhere.

Question No: 7

RouterA is unable to reach RouterB. Both routers are running IOS version 12.0.

After reviewing the command output and graphic, what is the most likely cause of the problem?

A. incorrect bandwidth configuration

B. incorrect LMI configuration

C. incorrect map statement

D. incorrect IP address

Answer: C

Explanation:

First we have to say this is an unclear question and it is wrong. The u201cframe-relay map ipu201d statement is correct thus none of the four answers above is correct. But we guess there is a typo in the output. Maybe the u201cip address 172.16.100.2 255.255.0.0 command should be u201cip address 172.16.100.1 255.255.0.0. That makes answer C correct.

Question No: 8

What is a valid HSRP virtual MAC address?

A. 0000.5E00.01A3

B. 0007.B400.AE01

C. 0000.0C07.AC15

D. 0007.5E00.B301

Answer: C

Explanation:

With HSRP, two or more devices support a virtual router with a fictitious MAC address and unique IP address. There are two version of HSRP.

+ With HSRP version 1, the virtual routeru2021s MAC address is 0000.0c07.ACxx , in which xx is the HSRP group.

+ With HSRP version 2, the virtual MAC address if 0000.0C9F.Fxxx, in which xxx is the HSRP group.

Note: Another case is HSRP for IPv6, in which the MAC address range from 0005.73A0.0000 through 0005.73A0.0FFF.

Question No: 9

Which commands are required to properly configure a router to run OSPF and to add network 192.168.16.0/24 to OSPF area 0? (Choose two.)

A. Router(config)# router ospf 0

B. Router(config)# router ospf 1

C. Router(config)# router ospf area 0

D. Router(config-router)# network 192.168.16.0 0.0.0.255 0

E. Router(config-router)# network 192.168.16.0 0.0.0.255 area 0

F. Router(config-router)# network 192.168.16.0 255.255.255.0 area 0

Answer: B,E

Explanation:

In the router ospf command, the ranges from 1 to 65535 so o is an invalid number -> but To configure OSPF, we need a wildcard in the u201cnetworku201d statement, not a subnet mask. We also need to assgin an area to this process ->.

Question No: 10

Which command would you use on a Cisco router to verify the Layer 3 path to a host?

A. tracert address

B. traceroute address

C. telnet address

D. ssh address

Answer: B

Explanation:

In computing, traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network. The history of the route is recorded as the round-trip times of the packets received from each successive host (remote node) in the route (path); the sum of the mean times in each hop indicates the total time spent to establish the connection. Traceroute proceeds unless all (three) sent packets are lost more than twice, then the connection is lost and the route cannot be evaluated. Ping, on the other hand, only computes the final round-trip times from the destination point.

Question No: 11

Which two tasks does the Dynamic Host Configuration Protocol perform? (Choose two.)

A. Set the IP gateway to be used by the network.

B. Perform host discovery used DHCPDISCOVER message.

C. Configure IP address parameters from DHCP server to a host.

D. Provide an easy management of layer 3 devices.

E. Monitor IP performance using the DHCP server.

F. Assign and renew IP address from the default pool.

Answer: C,F

Explanation:

The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to configure devices that are connected to a network (known as hosts) so they can communicate on that network using the Internet Protocol (IP). It involves clients and a server operating in a client-server model. DHCP servers assigns IP addresses from a pool of addresses and also assigns other parameters such as DNS and default gateways to hosts.

Question No: 12

Why will a switch never learn a broadcast address?

A. Broadcasts only use network layer addressing.

B. A broadcast frame is never forwarded by a switch.

C. A broadcast address will never be the source address of a frame.

D. Broadcast addresses use an incorrect format for the switching table.

E. Broadcast frames are never sent to switches.

Answer: C

Explanation:

Switches dynamically learn MAC addresses based on the source MAC addresses that it sees, and since a broadcast is never the source, it will never learn the broadcast address.

Question No: 13

A network interface port has collision detection and carrier sensing enabled on a shared twisted pair network. From this statement, what is known about the network interface port?

A. This is a 10 Mb/s switch port.

B. This is a 100 Mb/s switch port.

C. This is an Ethernet port operating at half duplex.

D. This is an Ethernet port operating at full duplex.

E. This is a port on a network interface card in a PC.

Answer: C

Explanation:

Modern Ethernet networks built with switches and full-duplex connections no longer utilize CSMA/CD. CSMA/CD is only used in obsolete shared media Ethernet (which uses repeater or hub).
