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，如果是useto console而不是connect就选B

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.

***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.

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!

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!

A. Show protocols.
B. Show protocol brief.

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?

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!
