  QUESTION NO: 18
  What can you use to connect a user’s pc directly to a router?
  A. Connect the PC's COM port to the router's console port using a
  straight-through cable.
  B. Connect the PC's COM port to the router's console port using a
  crossover cable.
  C. Connect the PC's COM port to the router's Ethernet port using a
  straight-through cable.
  D. Connect the PC's Ethernet port to the router's Ethernet port
  using a crossover cable.
  E. Connect the PC's Ethernet port to the router's Ethernet port
  using a rollover cable.
  F. Connect the PC's Ethernet port to the router's Ethernet port
  using a straight-through cable.
  Answer: D.
  ***the answer D is correct,but lots of people confuse about the
  cable***
  straight-through calbe and crossover cable are used to connect LAN
  interfaces!
  when we connect pc-to-pc router-to-router pc-to-router
  switch-to-switch ... use crossover cable
  when we connect pc-to-switch router-to-switch ...use
  straight-through cable
  the rollover calbe can be used to connect console port and the PC's
  COM port.
  这道题主要看题干,假如是useto console而不是connect就选B
  QUESTION NO: 75
  Consider Frame Relay multipoint subinterfaces. Which is a valid
  statement?
  A. An IP address is required on the physical interface of the
  central router.
  B. All routers are required to be fully meshed.
  C. All routers must be in the same subnet to forward routing updates
  and broadcasts.
  D. Multipoint is the default configuration for Frame Relay
  subinterfaces.
  Answer: D
  ***the correct answer should be C***
  Sybex study guide CCNA 3.0 page 522:
  Multipoint Used when the router is the center of a star of virtual
  circuits. Uses a single
  subnet for all routers’ serial interfaces connected to the frame
  switch.
  IntrodUCtion to Cisco Rouer Configuration page 413:
  You must specify either multipoint or point-to-point; there is no
  default.
  这道题TK确实是错了

  ***We need not add other three networks***
  CiscoPRess CCNA Exam 640-607 Certification Guide page 431:
  The network command “matches” one or more interfaces on a router.
  For each interface,
  the network command causes the router to do three things:
  1 The router broadcasts or multicasts routing updates out an
  interface.
  2 The router listens for incoming updates on that same interface.
  3 The router, when sending an update, includes the subnet of that
  interface in the
  routing update.
  QUESTION NO: 109
  Julia telnets to a pc on a remote subnet, which MAC address will be
  present in the ARP table when you
  issue the show arp command?
  A. MAC address of the destination host Ethernet port.
  B. MAC address of the local router Ethernet port.
  C. MAC address of the destination router Serial port.
  D. MAC address of the local router Serial Port.
  Answer: A
  ***the correct answer should be B***
  the pc transfort the packets to local router, and the router find
  the best way to remote network, so we
  choose the answer B!
  QUESTION NO: 133
  You have a direct serial link to an adjacent router. You do not have
  connectivity, and when you run the
  show running-config the output says that the serial interface is
  shutdown.
  You issue the command: show interface s0
  What will the output include?
  A. Serial 0 is up, line protocol is down.
  B. Serial 0 is down, line protocol is down.
  C. Serial 0 is down, line protocol is up.
  D. Serial is administratively down, line protocol is down.
  E. Serial 0 is administratively down, line protocol is up.
  F. Serial 0 is administratively up, line protocol is down.
  Answer: B
  ***the correct answer should be D***
  I had tried it on boson router sim. Only you issued the command
  "shutdown" on an interface the running-config
  would say that the interface was "shutdown". Remember that the
  running-config just display our setting not the real status
  of the router! Because we had made the interface shutdown, the show
  interface s0 command would say that the interface was
  administratively
  down!
  QUESTION NO: 145
  You need to find out the IPX address on a Cisco 2500 series router.
  Which command displays all routed
  protocols and the interfaces on which the protocol is enabled?
  A. Show protocols.
  B. Show protocol brief.
  C. Show interfaces protocol.
  D. Show interfaces.
  E. Show routed.
  F. Show routed interfaces.
  Answer: D
  ***the correct answer should be A***
  the "show interfaces" command outputs ip protocol only!
  QUESTION NO: 202
  You are configuring R3 so that it can communicate with R2 on
  Ethernet port e1. What encapsulation
  should you use on s0 to setup this IPX network?
  A. SAP
  B. HDLC
  C. ARPA
  D. Novell-Ether
  Answer: D
  EXPlanation: In order for both routers to communicate they must be
  using the same type of encapsulation.
  Therefore e1 of router R3 must have novell-ether encapsulation.
  ***the answer is correct but the question should be:
  You are configuring R3 so that it can communicate with R2 on
  Ethernet port e1. What encapsulation
  should you use on e1 to setup this IPX network?
  QUESTION NO: 274
  What are two commands that you can use to view your access lists?
  (Choose two)
  A. Show filters.
  B. Show access-lists.
  C. Show IP access-list.
  D. Show running-Config.
  Answer: B, C
  ***the correct answer should be B,D***
  The command "show running-config" do output the contents of all
  access-lists, on the other hand the "show ip access-list" command
  can not output the ipx access-list!
  It is too bad I could not issue the "show ip access-list" command on
  boson sim software!
  QUESTION NO: 291
  Which of the following are true about layer 3 of the OSI model?

  G. It provides path selection for Internet work communication.
  Answer: A, B, C, G
  ***the better answer should be A,B,D,G***
  I am not sure about the answer, I choose the answer D.
  最后注重Flash题的密码输入问题。
