Cisco 200-125 Online Questions & Answers

• Question 741:

  Routing has been configured on the local router with these commands: Local(config)# ip route 0.0.0.0 0.0.0.0 192.168.1.1 Local(config)# ip route 10.1.0.0 255.255.255.0 192.168.2.2 Local(config)# ip route 10.1.0.0 255.255.0.0 192.168.3.3 Drag each destination IP address on the left to its correct next hop address on the right.

  Select and Place:

  

  

  ---

  If we have many entries matching for next hop ip address then the router will choose the one with most specific path to send the packet. This is called the “longest match” rule, the route with the most bits in the mask set to “1 will be chosen to route packet.

• Question 742:

  What Netflow component can be applied to an interface to track IPv4 traffic?

  A. flow monitor
  B. flow record
  C. flow sampler
  D. flow exporter
  A. flow monitor

  ---

  Flow monitors are the Flexible NetFlow component that is applied to interfaces to perform network traffic monitoring. Flow monitors consist of a record and a cache. You add the record to the flow monitor after you create the flow monitor. The

  flow monitor cache is automatically created at the time the flow monitor is applied to the first interface. Flow data is collected from the network traffic during the monitoring process based on the key and nonkey fields in the record, which is

  configured for the flow monitor and stored in the flow monitor cache.

  For example, the following example creates a flow monitor named FLOW-MONITOR-1 and enters Flexible NetFlow flow monitor configuration mode:

  Router(config)# flow monitor FLOW-MONITOR-1

  Router(config-flow-monitor)#

• Question 743:

  Scenario

  Refer to the topology. Your company has connected the routers R1, R2, and R3 with serial links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also connected to the routers R4 and R5.

  The EIGRP routing protocol is configured.

  You are required to troubleshoot and resolve the EIGRP issues between the various routers.

  Use the appropriate show commands to troubleshoot the issues.

  

  Study the following output taken on R1:

  R1# Ping 10.5.5.55 source 10.1.1.1

  Type escape sequence to abort.

  Sending 5, 100-byte ICMP Echos to 10.5.5.55, timeout is 2 seconds:

  Packet sent with a source address of 10.1.1.1

  .......

  Success rate is 0 percent (0/5)

  Why are the pings failing?

  A. The network statement is missing on R5.
  B. The loopback interface is shut down on R5.
  C. The network statement is missing on R1.
  D. The IP address that is configured on the Lo1 interface on R5 is incorrect.
  A. The network statement is missing on R5.

• Question 744:

  What can be done to secure the virtual terminal interfaces on a router? (Choose two.)

  A. Administratively shut down the interface.
  B. Physically secure the interface.
  C. Create an access list and apply it to the virtual terminal interfaces with the access-group command.
  D. Configure a virtual terminal password and login process.
  E. Enter an access list and apply it to the virtual terminal interfaces using the access-class command.
  D. Configure a virtual terminal password and login process.
  E. Enter an access list and apply it to the virtual terminal interfaces using the access-class command.

  ---

  It is a waste to administratively shut down the interface. Moreover, someone can still access the virtual terminal interfaces via other interfaces -> We cannot physically secure a virtual interface because it is "virtual" ->. To apply an access list to a virtual terminal interface we must use the "access-class" command. The "access-group" command is only used to apply an access list to a physical interface -> C is not correct. The most simple way to secure the virtual terminal interface is to configure a username and password to prevent unauthorized login.

• Question 745:

  Which command can you enter to assign an interface to the default VLAN?

  A. Switch(config-if)# switchport access vlan 1
  B. Switch(config-if)# switchport trunk native vlan 1
  C. Switch(config-if)# vlan 1
  D. Switch(config)# int vlan 1
  A. Switch(config-if)# switchport access vlan 1

• Question 746:

  A router has learned three possible routes that could be used to reach a destination network. One route is from EIGRP and has a composite metric of 20514560. Another route is from OSPF with a metric of 782. The last is from RIPv2 and has a metric of 4. Which route or routes will the router install in the routing table?

  A. the OSPF route
  B. the EIGRP route
  C. the RIPv2 route
  D. all three routes
  E. the OSPF and RIPv2 routes
  B. the EIGRP route

  ---

  When one route is advertised by more than one routing protocol, the router will choose to use the routing protocol which has lowest Administrative Distance. The Administrative Distances of popular routing protocols are listed below:

  

• Question 747:

  How many bits represent network id in a IPv6 address?

  A. 32
  B. 48
  C. 64
  D. 128
  C. 64

  ---

  Explanation: http://networkengineering.stackexchange.com/questions/30836/calculate-networking-bits- for-ipv6 64 bits for Network ID and 64 bits for Interface ID 64+64=128

• Question 748:

  Describe the best way to troubleshoot and isolate a network problem?

  A. Create an action plan
  B. Implement an action plan
  C. Gather facts
  D. Change on variable at a time
  C. Gather facts

• Question 749:

  What are two advantages of dynamic routing? (Choose two)

  A. It produces minimal CPU load.
  B. It can load-balance traffic over multiple link without manual intervention
  C. It allows the network administrator to choose the best route.
  D. it can be implemented easily even in large environments.
  E. it can operate without a Layer 3 device
  C. It allows the network administrator to choose the best route.
  D. it can be implemented easily even in large environments.

• Question 750:

  Examine the DHCP configuration between R2 and R3,R2 is configured as the DHCP server and R3 as the client.

  

  What is the reason R3 is not receiving the IP address via DHCP?

  A. On R3,DHCP is not enabled on the interface that is connected to R2.
  B. On R3,the interface that is connected to R2 is in shutdown condition.
  C. On R2, the interface that is connected to R3 is in shutdown condition
  D. On R2, the network statement in the DHCP pool configuration is incorrectly configured
  A. On R3,DHCP is not enabled on the interface that is connected to R2.
