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

Q1. Refer to the exhibit.

The network shown in the diagram is experiencing connectivity problems. Which of the following will correct the problems? (Choose two.)

A. Configure the gateway on Host A as

B. Configure the gateway on Host B as

C. Configure the IP address of Host A as

D. Configure the IP address of Host B as

E. Configure the masks on both hosts to be

F. Configure the masks on both hosts to be

Answer: B,D


The switch 1 is configured with two VLANs: VLAN1 and VLAN2. The IP information of member Host A in VLAN1 is as follows: Address :

Mask :

Gateway :

The IP information of member Host B in VLAN2 is as follows: Address :

Mask :

Gateway :

The configuration of sub-interface on router 2 is as follows: Fa0/0.1 -- VLAN1

Fa0/0.2 -- VLAN2

It is obvious that the configurations of the gateways of members in VLAN2 and the associated network segments are wrong. The layer3 addressing information of Host B should be modified as follows:

Address : 10.1.2.X Mask :

Q2. Which IPv6 address is the all-router multicast group?

A. FF02::1

B. FF02::2

C. FF02::3

D. FF02::4

Answer: B


Well-known IPv6 multicast addresses:

Address Description ff02::1

All nodes on the local network segment


All routers on the local network segment

Q3. Refer to exhibit.

A network administrator cannot establish a Telnet session with the indicated router. What is the cause of this failure?

A. A Level 5 password is not set.

B. An ACL is blocking Telnet access.

C. The vty password is missing.

D. The console password is missing.

Answer: C


The login keyword has been set, but not password. This will result in the u201cpassword

required, but none setu201d message to users trying to telnet to this router.

Q4. Which IPv6 address is valid?

A. 2001:0db8:0000:130F:0000:0000:08GC:140B

B. 2001:0db8:0:130H::87C:140B

C. 2031::130F::9C0:876A:130B

D. 2031:0:130F::9C0:876A:130B

Answer: D


An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits (two octets). The groups are separated by colons (:). An example of an IPv6 address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. The leading 0u2019s in a group can be collapsed using ::, but this can only be done once in an IP address.

Q5. What are the benefits of using Netflow? (Choose three.)

A. Network,Application & User Monitoring

B. Network Planning

C. Security Analysis

D. Accounting/Billing

Answer: A,C,D


NetFlow traditionally enables several key customer applications including:

+ Network Monitoring u2013 NetFlow data enables extensive near real time network monitoring capabilities. Flow-based analysis techniques may be utilized to visualize traffic patterns associated with individual routers and switches as well as on a network-wide basis (providing aggregate traffic or application based views) to provide proactive problem detection, efficient troubleshooting, and rapid problem resolution.

+ Application Monitoring and Profiling u2013 NetFlow data enables network managers to gain a detailed, time-based, view of application usage over the network. This information is used to plan, understand new services, and allocate network and application resources (e.g. Web server sizing and VoIP deployment) to responsively meet customer demands.

+ User Monitoring and Profiling u2013 NetFlow data enables network engineers to gain detailed understanding of customer/user utilization of network and application resources. This information may then be utilized to efficiently plan and allocate access, backbone and

application resources as well as to detect and resolve potential security and policy violations.

+ Network Planning u2013 NetFlow can be used to capture data over a long period of time producing the opportunity to track and anticipate network growth and plan upgrades to increase the number of routing devices, ports, or higher- bandwidth interfaces. NetFlow services data optimizes network planning including peering, backbone upgrade planning, and routing policy planning. NetFlow helps to minimize the total cost of network operations while maximizing network performance, capacity, and reliability. NetFlow detects unwanted WAN traffic, validates bandwidth and Quality of Service (QOS) and allows the analysis of new network applications. NetFlow will give you valuable information to reduce the cost of operating your network.

+ Security Analysis u2013 NetFlow identifies and classifies DDOS attacks, viruses and worms in real-time. Changes in network behavior indicate anomalies that are clearly demonstrated in NetFlow data. The data is also a valuable forensic tool to understand and replay the history of security incidents.

+ Accounting/Billing u2013 NetFlow data provides fine-grained metering (e.g. flow data includes details such as IP addresses, packet and byte counts, timestamps, type-of-service and application ports, etc.) for highly flexible and detailed resource utilization accounting. Service providers may utilize the information for billing based on time-of-day, bandwidth usage, application usage, quality of service, etc. Enterprise customers may utilize the information for departmental charge-back or cost allocation for resource utilization.

Q6. You have been asked to come up with a subnet mask that will allow all three web servers to be on the same network while providing the maximum number of subnets. Which network address and subnet mask meet this requirement?






Answer: B


A subnet mask of will allow for up to 6 hosts to reside in this network. A subnet mask of will allow for only 2 usable IP addresses, since we cannot use the network or broadcast address.

Q7. Which two statements describe characteristics of IPv6 unicast addressing? (Choose two.)

A. Global addresses start with 2000::/3.

B. Link-local addresses start with FE00:/12.

C. Link-local addresses start with FF00::/10.

D. There is only one loopback address and it is ::1.

E. If a global address is assigned to an interface, then that is the only allowable address for the interface.

Answer: A,D


Below is the list of common kinds of IPv6 addresses:

Q8. Scenario

Refer to the topology. Your company has decided to connect the main office with three other remote branch offices using point-to-point serial links.

You are required to troubleshoot and resolve OSPF neighbor adjacency issues between the main office and the routers located in the remote branch offices.

An OSPF neighbor adjacency is not formed between R3 in the main office and R6 in the Branch3 office. What is causing the problem?

A. There is an area ID mismatch.

B. There is a PPP authentication issue; the username is not configured on R3 and R6.

C. There is an OSPF hello and dead interval mismatch.

D. The R3 router ID is configured on R6.

Answer: D


Using the show running-config command we see that R6 has been incorrectly configured with the same router ID as R3 under the router OSPF process.

Q9. Refer to the exhibit.

What statement is true of the configuration for this network?

A. The configuration that is shown provides inadequate outside address space for translation of the number of inside addresses that are supported.

B. Because of the addressing on interface FastEthernet0/1, the Serial0/0 interface address will not support the NAT configuration as shown.

C. The number 1 referred to in the ip nat inside source command references access-list number 1.

D. ExternalRouter must be configured with static routes to networks and

Answer: C


The u201clist 1 refers to the access-list number 1.

Q10. CORRECT TEXTA network associate is adding security to the configuration of the Corp1 router. The user on host C should be able to use a web browser to access financial information from the Finance Web Server. No other hosts from the LAN nor the Core should be able to use a web browser to access this server. Since there are multiple resources for the corporation at this location including other resources on the Finance Web Server, all other traffic should be allowed.

The task is to create and apply an access-list with no more than three statements that will allow ONLY host C web access to the Finance Web Server. No other hosts will have web access to the Finance Web Server. All other traffic is permitted.

Access to the router CLI can be gained by clicking on the appropriate host. All passwords have been temporarily set to "cisco".

The Core connection uses an IP address of

The computers in the Hosts LAN have been assigned addresses of -

u2711 host A

u2711 host B

u2711 host C

u2711 host D

The servers in the Server LAN have been assigned addresses of -

The Finance Web Server is assigned an IP address of


Select the console on Corp1 router Configuring ACL

Corp1>enable Corp1#configure terminal

comment: To permit only Host C ({source addr} to access finance server address ( {destination addr} on port number 80 (web) Corp1(config)#access-list 100 permit tcp host host eq 80 comment: To deny any source to access finance server address (

{destination addr} on port number 80 (web)

Corp1(config)#access-list 100 deny tcp any host eq 80

comment: To permit ip protocol from any source to access any destination because of the implicit deny any any statement at the end of ACL.

Corp1(config)#access-list 100 permit ip any any Applying the ACL on the Interface

comment: Check show ip interface brief command to identify the interface type and number by checking the IP address configured.

Corp1(config)#interface fa 0/1

If the ip address configured already is incorrect as well as the subnet mask. This should be corrected in order ACL to work

type this commands at interface mode :

no ip address 192.x.x.x 255.x.x.x (removes incorrect configured ipaddress and subnet mask)

Configure Correct IP Address and subnet mask:

ip address ( range of address specified going to server is given as - )

Comment: Place the ACL to check for packets going outside the interface towards the

finance web server.

Corp1(config-if)#ip access-group 100 out Corp1(config-if)#end

Important: To save your running config to startup before exit. Corp1#copy running-config startup-config

Verifying the Configuration:

Step1: show ip interface brief command identifies the interface on which to apply access list.

Step2: Click on each host A, B, C, & D. Host opens a web browser page, Select address box of the web browser and type the ip address of finance web server ( to test whether it permits /deny access to the finance web Server.

Step 3: Only Host C ( has access to the server. If the other host can also access then maybe something went wrong in your configuration. Check whether you configured correctly and in order.

Step 4: If only Host C ( can access the Finance Web Server you can click on NEXT button to successfully submit the ACL SIM.
