Answer: B

Cisco's encapsulation for Frame relay is proprietary. To
communicate

with non-Cisco equipment when using frame-relay
encapsulation, the IETF

method must be used.

You must use IETF encapsulation when connecting to non-
cisco equipment

Answer: C

The 802.2 Frame Type is the default frame-type for Netware 3.12.

Answer: C

The Address Resolution Protocol (ARP) resolved IP addresses
to MAC

addresses.

C.) Address Resolution Protocol
·ARP was invented for this reason . It relates IP’s to MAC 
addresses only on media that supports broadcasts . 
·Each node maintains a cache called the ARP cache , which 
holds a table of IP’s against MAC addresses .

Answer: B

The syntax is: set type duplex slot/port

Answer: C

Static routes are typically used when there are very few
routes and you

want to conserve bandwidth. Since routing protocols are
constantly

sending their updates across the wire, it can cause a great
deal of

congestion.

Answer: A

Statically connected routes are those that an administrator
has manually

entered into the routing table.

The correct answer(s): B

TCP provides guaranteed connection oriented delivery of
packets, UDP

does not.

B.) TCP is connection-oriented; UDP is connectionless

Answer: C E

When determining which subnet mask to use, you must
determine how many

hosts and how many subnets are required.

Answer: B

Routing Information Protocol (RIP) is a distance vector
routing protocol

that used hop count as its metric. The maximum hop count is
15, 16 hops

is considered unreachable. RIP updates are broadcast every
30 seconds by

default. RIP has an administrative distance of 120.

B.) Destination unreachable

Answer: 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 received is retransmitted by the sender.

Answer: 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.

Answer: 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.

Answer: C

A repeater regenerates the signal it receives, a switch
makes decisions

based upon MAC addresses to determine whether a frame should be

forwarded. Repeaters forward all packets.

Answer: D

Cisco's implementation of HDLC is only compatible with Cisco
routers. It

is the default encapsulation type for serial interfaces.

Answer: C

15 is the maximum hop count, underscoring the size
limitation of RIP.
