Cisco 200-105 Online Questions & Answers

• Question 61:

  Which WAN topology has the highest degree of reliability?

  A. hub-and-spoke
  B. full mesh
  C. point-to-point
  D. router-on-a-stick
  B. full mesh

• Question 62:

  Which two components are used to identify a neighbor in a BGP configuration? (Choose two.)

  A. autonomous system number
  B. version number
  C. router ID
  D. subnet mask
  E. IP address
  A. autonomous system number
  E. IP address

  ---

  Use the show ip bgp neighbors (registered customers only) command to display information about the TCP and Border Gateway Protocol (BGP) connections and verify if the BGP peer is established. The output of the show ip bgp neighbors

  command below shows the BGP state as 'Established', which indicates that the BGP peer relationship has been established successfully.

  R1-AGS# show ip bgp neighbors | include BGP

  BGP neighbor is 10.10.10.2, remote AS 400, internal link BGP version 4, remote router ID 2.2.2.2 BGP state = Established, up for 00:04:20 BGP table version 1, neighbor version 1

  R1-AGS#

  The show ip bgp neighbors command has been used above with the modifier | include BGP. This makes the output more readable by filtering the the command output and displaying the relevant parts only.

  In addition, the show ip bgp summary (registered customers only) command can also be used to display the status of all BGP connections, as shown below.

  R1-AGS(9)# show ip bgp summary

  BGP router identifier 10.1.1.2, local AS number 400 BGP table version is 1, main routing table version 1

  Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd 10.10.10.2 4 400 3 3 1 0 0 00:00:26 0

• Question 63:

  Which two statements describe the process identifier that is used in the command to configure OSPF on a router? (Choose two.) Router(config)# router ospf 1

  A. All OSPF routers in an area must have the same process ID.
  B. Only one process number can be used on the same router.
  C. Different process identifiers can be used to run multiple OSPF processes
  D. The process number can be any number from 1 to 65,535.
  E. Hello packets are sent to each neighbor to determine the processor identifier.
  C. Different process identifiers can be used to run multiple OSPF processes
  D. The process number can be any number from 1 to 65,535.

  ---

  We all know that the areas can be any number from 0 to 4.2 billion and 1 to 65,535 for the Process ID. The process ID is the ID of the OSPF process to which the interface belongs. The process ID is local to the router, and two OSPF

  neighboring routers can have different OSPF process IDs.

  (This is not true of Enhanced Interior Gateway Routing Protocol [EIGRP], in which the routers need to be in the same autonomous system). Cisco IOS Software can run multiple OSPF processes on the same router, and the process ID merely

  distinguishes one process from the another. The process ID should be a positive integer.

• Question 64:

  Refer to the exhibit. What is the result of setting the no login command?

  

  A. Both SSH and Telnet access is denied.
  B. Both SSH and Telnet access requires a password.
  C. Both SSH and Telnet access requires a new password at first login.
  D. There is a virtually limitless supply of IP addresses.
  A. Both SSH and Telnet access is denied.

• Question 65:

  Refer to the exhibit.

  Given the output for this command, if the router ID has not been manually set, what router ID will OSPF use for this router?

  

  A. 10.1.1.2
  B. 10.154.154.1
  C. 172.16.5.1
  D. 192.168.5.3
  C. 172.16.5.1

  CCNA Tutorial: The OSPF Router ID (RID)

  When determining the Router ID (RID) of an OSPF-enabled router, OSPF will always use the numerically highest IP address on the router's loopback interfaces, regardless of whether that loopback is OSPF-enabled.

  What if there is no loopback?

  OSPF will then use the numerically highest IP address of the physical interfaces, regardless of whether that interface is OSPF-enabled.

• Question 66:

  While troubleshooting a connection problem on a computer, you determined that the computer can ping a specific web server but it cannot connect to TCP port 80 on that server. Which reason for the problem is most likely true?

  A. A VLAN number is incorrect
  B. An ARP table entry is missing
  C. A route is missing
  D. An ACL is blocking the TCP port
  D. An ACL is blocking the TCP port

• Question 67:

  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.

  Use appropriate show commands to troubleshoot the issues and answer all four questions.

  Instructions

  Enter Cisco IOS commands on the device to verify network operation and answer the multiple-choice questions.

  THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION.

  Click on the device to gain access to the console of the device. No console or enable passwords are required.

  To access the multiple-choice questions, click on the numbered boxes on the left of the top panel.

  There are four multiple-choice questions with this task. Be sure to answer all four questions before clicking the Next button.

  

  

  

  An OSPF neighbor adjacency is not formed between R3 in the main office and R5 in the Branch2 office. What is causing the problem?

  A. There is an area ID mismatch.
  B. There is a PPP authentication issue; a password mismatch.
  C. There is an OSPF hello and dead interval mismatch.
  D. There is a missing network command in the OSPF process on R5.
  C. There is an OSPF hello and dead interval mismatch.

  ---

  The "show ip ospf interface command on R3 and R5 shows that the hello and dead intervals do not match. They are 50 and 200 on R3 and 10 and 40 on R5.

  

• Question 68:

  Which two pieces of information are provided by the show controllers serial 0 command? (Choose two.)

  A. the type of cable that is connected to the interface
  B. the uptime of the interface
  C. the status of the physical layer of the interface
  D. the full configuration of the interface
  E. the interface's duplex settings
  A. the type of cable that is connected to the interface
  C. the status of the physical layer of the interface

• Question 69:

  Which three describe the reasons large OSPF networks use a hierarchical design? (Choose three.)

  A. to speed up convergence
  B. to reduce routing overhead
  C. to lower costs by replacing routers with distribution layer switches.
  D. to decrease latency by increasing bandwidth.
  E. to confine network instability to single areas of the network.
  F. to reduce the complexity of router configuration.
  A. to speed up convergence
  B. to reduce routing overhead
  E. to confine network instability to single areas of the network.

• Question 70:

  Which feature would prevent a workstation from receiving a DHCP address?

  A. STP
  B. 802.1Q
  C. VTP
  D. DTP
  A. STP
