New Cisco 200-125 Exam Dumps Collection (Question 1 - Question 10)
New Questions 1
A network administrator creates a layer 3 EtherChannel, bundling four interfaces into channel group 1. On what interface is the IP address configured?
A. the port-channel 1 interface
B. the highest number member interface
C. all member interfaces
D. the lowest number member interface
Answer: A
Explanation:
To create an EtherChannel interface and assign its IP address and subnet mask, use the following steps beginning in global configuration mode:
Command Purpose Step 1
Router(config)#interface port-channelchannel-number
Router(config-if)#
Creates the EtherChannel interface. You can configure up to 16 FECs and 1 GEC on the Catalyst 2948G-L3 and up to 4 GECs on the Catalyst 4908G-L3.
Step 2
Router(config-if)#ip addressip-address subnet-mask
Assigns an IP address and subnet mask to the EtherChannel interface.
Step 3 Router(config-if)#exit Router(config)#
Exits this mode. Optionally, you can remain in interface configuration mode and enable other supported interface commands to meet
The IP address is assigned to the port channel interface, not the underlying physical member interfaces.

New Questions 2
Which command allows you to verify the encapsulation type (CISCO or IETF) for a Frame Relay link?
A. show frame-relay lmi
B. show frame-relay map
C. show frame-relay pvc
D. show interfaces serial
Answer: B
Explanation:
When connecting Cisco devices with non-Cisco devices, you must use IETF4 encapsulation on both devices. Check the encapsulation type on the Cisco device with the show frame-relay mapexec command.
New Questions 3
The network administrator cannot connect to Switch1 over a Telnet session, although the hosts attached to Switch1 can ping the interface Fa0/0 of the router.
Given the information in the graphic and assuming that the router and Switch2 are configured properly, which of the following commands should be issued on Switch1 to correct this problem?
A. Switch1(config)# line con0 Switch1(config-line)# password cisco Switch1(config-line)#login
B. Switch1(config)# interface fa0/1
Switch1(config-if)# ip address 192.168.24.3 255.255.255.0
C. Switch1(config)# ip default-gateway 192.168.24.1
D. Switch1(config)# interface fa0/1 Switch1(config-if)# duplex full
Switch1(config-if)# speed 100
E. Switch1(config)# interface fa0/1 Switch1(config-if)# switchport mode trunk
Answer: C
Explanation:
Since we know hosts can reach the router through the switch, we know that connectivity, duplex. Speed, etc. are good. However, for the switch itself to reach networks outside the local one, the ip default-gateway command must be used.
New Questions 4
Users have been complaining that their Frame Relay connection to the corporate site is very slow. The network administrator suspects that the link is overloaded.
Based on the partial output of the Router# show frame relay pvc command shown in the graphic, which output value indicates to the local router that traffic sent to the corporate site is experiencing congestion?
A. DLCI = 100
B. last time PVC status changed 00:25:40
C. in BECN packets 192
D. in FECN packets 147
E. in DE packets 0
Answer: C
Explanation:
If device A is sending data to device B across a Frame Relay infrastructure and one of the intermediate Frame Relay switches encounters congestion, congestion being full buffers, over-subscribed port, overloaded resources, etc, it will set the BECN bit on packets being returned to the sending device and the FECN bit on the packets being sent to the receiving device.
New Questions 5
Refer to the exhibit.
All of the routers in the network are configured with the ip subnet-zero command. Which network addresses should be used for Link A and Network A? (Choose two.)
A. Network A - 172.16.3.48/26
B. Network A - 172.16.3.128/25
C. Network A - 172.16.3.192/26
D. Link A - 172.16.3.0/30
E. Link A - 172.16.3.40/30
F. Link A - 172.16.3.112/30
Answer: B,D
Explanation:
Only a /30 is needed for the point to point link and sine the use of the ip subnet-zero was used, 172.16.3.0/30 is valid. Also, a /25 is required for 120 hosts and again
172.16.3.128/25 is the best, valid option.
New Questions 6
The network administrator needs to address seven LANs. RIP version 1 is the only routing protocol in use on the network and subnet 0 is not being used. What is the maximum number of usable IP addresses that can be supported on each LAN if the organization is using one class C address block?
A. 8
B. 6
C. 30
D. 32
E. 14
F. 16
Answer: C
Explanation:
Since there is one class C network that means 256 total IP addresses. Since we need 7
LAN blocks and we cannot use the first one (subnet 0) we take 256/8=32 hosts. However, since we need to reserve the network and broadcast addresses for each of these subnets, only 30 total IP addresses are usable.
New Questions 7
What command is used to verify the DLCI destination address in a Frame Relay static configuration?
A. show frame-relay pvc
B. show frame-relay lmi
C. show frame-relay map
D. show frame relay end-to-end
Answer: C
Explanation:
Sample u201cshow frame-relay mapu201d output: R1#sh frame map
Serial0/0 (up): ip 10.4.4.1dlci 401(0x191,0x6410), dynamic, broadcast,, status defined, active
Serial0/0 (up): ip 10.4.4.3dlci 403(0x193,0x6430), dynamic, broadcast,, status defined, active
Serial0/0 (up): ip 10.4.4.4dlci 401(0x191,0x6410), static, CISCO, status defined, active
New Questions 8
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 ->.
New Questions 9
Which statement describes the process ID that is used to run OSPF on a router?
A. It is globally significant and is used to represent the AS number.
B. It is locally significant and is used to identify an instance of the OSPF database.
C. It is globally significant and is used to identify OSPF stub areas.
D. It is locally significant and must be the same throughout an area.
Answer: B
Explanation:
The Process ID for OSPF on a router is only locally significant and you can use the same number on each router, or each router can have a different number-it just doesn't matter. The numbers you can use are from 1 to 65,535. Don't get this confused with area numbers, which can be from 0 to 4.2 billion.
New Questions 10
Which two statements about using the CHAP authentication mechanism in a PPP link are true? (Choose two.)
A. CHAP uses a two-way handshake.
B. CHAP uses a three-way handshake.
C. CHAP authentication periodically occurs after link establishment.
D. CHAP authentication passwords are sent in plaintext.
E. CHAP authentication is performed only upon link establishment.
F. CHAP has no protection from playback attacks.
Answer: B,C
Explanation:
CHAP is an authentication scheme used by Point to Point Protocol (PPP) servers to validate the identity of remote clients. CHAP periodically verifies the identity of the client by using a three-way handshake. This happens at the time of establishing the initial link (LCP), and may happen again at any time afterwards. The verification is based on a shared secret (such as the client user's password).
