131 Identify the hardware
component used to store buffers, tables, running-configuration
etc?
A.) NVRAM
B.) ROM
C.) RAM
D.) Flash
Ans C
RAM is the dynamic memory area. ROM contains the boot strap
code, NVRAM contains the startup-config and Flash contains the
IOS.
132 Identify 3 UDP characteristics?
A.) Reliable communication protocol
B.) Applications that use UDP must incorporate reliability
C.) Connection-less oriented
D.) Incorporates no handshaking
Ans B C D
UPD is a layer 4 Transport protocol. It is connection-less
because it does establish a connection therefore the 3 step
handshake is not needed, it does NOT implement any flow control
or acknowledgments. Any application that uses UDP must
incorporate any needed reliability.
133 Identify the IPX standard access-list number range?
A.) 600 - 699
B.) 1000 - 1099
C.) 1 - 99
D.) 100 - 199
E.) 800 - 899
Ans E
IPX standard access-list range is 800-899.
134 Which OSI layer provides best effort end to end packet
delivery?
A.) Data-Link
B.) Presentation
C.) Network
D.) Transport
E.) Physical
F.) Application
Ans C
Layer 3 the Network layer performs this function.
135 Identify the 2 methods to modify the routers boot
sequence?
A.) Setup program
B.) Boot system commands
C.) RXBoot
D.) Config-register
Ans B D
'Boot system' command the 'config-register' are used to
manipulate the boot sequence.
136 Identify the 3 pieces of hardware you would not install
to prevent broadcasts?
A.) Switch
B.) Repeater
C.) Bridge
D.) Router
Ans A B C
Router are implemented not only to break up networks into
smaller segments but they are used to block broadcasts.
137 Identify 2 features of PPP PAP authentication?
A.) Username and password is sent in clear text
B.) Authentication messages are sent periodically during the
connection
C.) More secure than CHAP
D.) Remote node is control of authentication process
Ans A D
PPP PAP authentication sends the username and passwords in clear
text and the remote node initiates the authentication process.
138 Identify the switching method that examines the
destination MAC address as the frame is being received then
begins forwarding the frame prior to receiving the entire frame?
A.) Fragment-free
B.) Store and Forward
C.) Cut-through
D.) Fast forward
Ans C
Cut through examines the destination MAC address and begins
forwarding the frame prior to receiving the entire frame.
139 Identify 1 characteristic of RARP?
A.) IP to MAC address translation
B.) Connectionless delivery of packets
C.) Can be used to initiate remote O/S load sequence
D.) Generates error and control messages
Ans C
Reverse Address Resolution Protocol is used to obtain a layer 3
address if the MAC address is known which then facilitates the
loading of the O/S.
140 Identify the protocol to test connectivity without
configuring any layer 3 protocols?
A.) TCP
B.) Ping
C.) IP
D.) CDP
E.) Telnet
Ans D
CDP can be used to verify connectivity prior to any layer 3
protocols being configured.
