access-list you used. Which command lets you see all access-lists on
Serial 0 for telnet?
A.) show access-list
B.) show ip int s0
C.) show access-list telnet
D.) show telnet access-list
E.) show access-list s0
F.) show int s0

The correct answer(s): B
To see which access-lists are bound to an interface, you must specifiy the
protocol.
Since these were for controlling telnet, and telnet uses IP, the correct
answer can only be 'show ip int s0'
show ip int s0
show ipx int s0
show appletalk int s0



114. Cisco routers can secure the enable password with a one-way hash
algorithm. What command would encrypt the enable password with the strong
encryption method?

C.) enable secret john
D.) enable password john
E.) secret john
F.) enable password 5 john

The correct answer(s): C
Sybex CCNA Study Guide: Chapter 5
On current Cisco routers, there are two 'enable' password methods. One is
to use the old 'enable' password method, which is very easy to crack. The
newer 'Secret' method uses Message Digest 5 (MD5) encryption, and is very
difficult to crack. If both 'Enable' and 'Secret' passwords exist, the
'Secret' will always be used and the 'Enable' will be ignored.

252. Ping uses which Internet layer protocol?
A.) RARP
B.) ICMP
C.) ARP
D.) FTP

The correct answer(s): B
Internet Control Message Protocol - ICMP is a management protocol and
messaging service provider for IP. Its messages are carried as IP
datagrams.

ICMP is used in the following events:

Destination Unreachable - If a router cannot send an IP packet any
further, it uses an ICMP echo to send a message back to the sender
notifying it that the remote node is unreachable.

Buffer Full - If a routers memory buffer is full ICMP will send out a
message to the originator.

Hops - Each IP datagram is assigned a path. This consists of hops. If it
goes through the maximum number of hops, the packet is discarded and the
discarding router sends an ICMP echo to the host.

Ping - Ping use ICMP echo message to check connectivity.


253. Which is true regarding store-and-forward switching method?
A.) Latency varies depending on frame-length
B.) Latency is constant
C.) It is default for all Cisco switches
D.) It only reads the destination hardware address before forwarding the
frame

The correct answer(s): A
Store-and-Forward switching copies the entire frame into its buffer and
computes the CRC. If a CRC error is detected, the frame is discarded, or
if the frame is a runt (less than 64 bytes including the CRC) or a giant
(more than 1518 bytes including the CRC). The LAN switch then looks up the
destination address in its switching table and determines the outgoing
interface. The frame is then forwarded to the outgoing interface. Cisco
Catalyst 5000 switches uses the Store-and-Forward method. The problem with
Store-and-Forward switching is latency is increased. Latency also varies
with the size of the frame. The larger the frame, the more latency
associated. This of course is due to the fact that the entire frame is
copied into its buffer before being forwarded.


254. Which three of the following are true statements about connection-oriented
sessions?
A.) The segments delivered are acknowledged back to the sender upon their
reception
B.) Any segments not acknowledged are retransmitted by the receiver
C.) A manageable data flow is maintained in order to avoid congestion,
overloading and loss of any data
D.) Segments are sequenced back into their proper order upon arrival at
their destination

The correct answer(s): A C D
Connection-oriented services are useful for transmitting data from
applications that are intolerant of delays and packet re-sequencing. FTP
and Telnet applications are based on connection-oriented services as well
as some voice and video programs. Any segment that is not acknowledged by
the recevied is retransmitted by the sender.


What does a metric of 16 hops represent when using RIP?
A.) Number of hops to the destination
B.) Destination unreachable
C.) Number of routers
D.) Bandwidth

The correct answer(s): B
Routing Information Protocol (RIP) is a distance vector routing protocol
