Cisco 200-105 Online Questions & Answers

• Question 81:

  Which statement about link-state and distance-vector routing protocols is true?

  A. Unlike distance-vector routing protocols, link-state routing protocols can cause routing loops.
  B. Distance-vector routing protocols converge more quickly than link-state routing protocols.
  C. Distance-vector routing protocols use more memory than link-state routing protocols.
  D. Unlike distance-vector routing protocols, link-state routing protocols send routing-table updates to neighbors only after adjacency is established.
  D. Unlike distance-vector routing protocols, link-state routing protocols send routing-table updates to neighbors only after adjacency is established.

• Question 82:

  Which command do you enter to determine the root priority?

  A. Show spanning-tree mapping
  B. Show spanning-tree summary
  C. Show spanning-tree bpdu-filter 1
  D. Show spanning-tree backbonefast
  B. Show spanning-tree summary

• Question 83:

  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 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.
  D. The R3 router ID is configured on R6.

  ---

  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.

  

• Question 84:

  How can you manually configure a switch so that it is selected as the root Switch?

  A. increase the priority number
  B. lower the port priority number
  C. lower the priority number
  D. increase the port priority number
  C. lower the priority number

• Question 85:

  Which two authentication methods are compatible with MLPPP on a serial interface? (Choose two.)

  A. LEAP
  B. PEAP
  C. CHAP
  D. TACACS+
  E. PAP
  C. CHAP
  E. PAP

  PPP Authentication Methods

  In this part we will learn more about two authentication methods used in Authentication Phase of PPP.

  PPP has two built-in security mechanisms which are Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP).

• Question 86:

  Which feature can you implement to reserve bandwidth for voip calls across the call path?

  A. PQ
  B. Round Robin
  C. CBWFQ
  D. RSPV
  D. RSPV

• Question 87:

  What's DTP's default in a switch?

  A. ON
  B. OFF
  C. Dynamic Desirable
  D. Dynamic Auto
  D. Dynamic Auto

• Question 88:

  What can be done to Frame Relay to resolve split-horizon issues? (Choose two.)

  A. Disable Inverse ARP.
  B. Create a full-mesh topology.
  C. Develop multipoint subinterfaces.
  D. Configure point-to-point subinterfaces.
  E. Remove the broadcast keyword from the frame-relay map command.
  B. Create a full-mesh topology.
  D. Configure point-to-point subinterfaces.

  ---

  IP split horizon checking is disabled by default for Frame Relay encapsulation to allow routing updates to go in and out of the same interface. An exception is the Enhanced Interior Gateway Routing Protocol (EIGRP) for which split horizon must be explicitly disabled. Certain protocols such as AppleTalk, transparent bridging, and Internetwork Packet Exchange (IPX) cannot be supported on partially meshed networks because they require split horizon to be enabled (a packet received on an interface cannot be transmitted over the same interface, even if the packet is received and transmitted on different virtual circuits). Configuring Frame Relay subinterfaces ensures that a single physical interface is treated as multiple virtual interfaces. This capability allows you to overcome split horizon rules so packets received on one virtual interface can be forwarded to another virtual interface, even if they are configured on the same physical interface.

• Question 89:

  Which two characteristics of eBGP peers are true? (Choose two.)

  A. They must be directly connected
  B. They must reside in different IP subnets
  C. They must reside in the same autonomous system
  D. They must reside in the same IP subnet
  E. They must reside in two different autonomous systems
  A. They must be directly connected
  E. They must reside in two different autonomous systems

• Question 90:

  What do SNMPv1 and SNMPv2 have in common?

  A. They use the same authentication techniques.
  B. They both use the local database to permit username access.
  C. They both protect against message tampering in transit.
  D. They both encrypt packets.
  A. They use the same authentication techniques.
