171 Identify 3 characteristics
of a MAC address?
A.) Burned into the NIC
B.) 48 bits long
C.) Length is 32 bits
D.) Used to deliver the frame to the end device
E.) Contains a network portion and a host portion
Ans A B D
The MAC address is 48 bits long not 32. It does NOT contain a
network and host portion with the address. It is used to deliver
the frame to the destination device.
172 Identify 3 IP routing protocols?
A.) RIP
B.) AURP
C.) OSPF
D.) IGRP
E.) ARP
F.) ICMP
Ans A C D
AURP and ICMP are not routing protocols.
173 Identify the type of routing protocol that exchanges
entire routing tables at regular intervals?
A.) Link state
B.) Interior gateway protocols
C.) Appletalk routing
D.) Distance vector
Ans D
Distance Vector routing protocols exchange entire routing tables
with it's neighbors. Link State routing protocols exchange LSP's
to share information regarding the networks they know.
174 Identify the type of hardware required to connect a Token
ring network to an Ethernet network?
A.) Repeater
B.) TR-Enet
C.) Router
D.) Token Ring to Ethernet translation hub
Ans C
Routers are used to connect dissimilar networks with different
access-methods, like connecting Token Ring to Ethernet.
175 Identify 3 characteristics regarding CDP?
A.) On by default
B.) Shows only directly connected neighbors
C.) Requires IP or IPX
D.) 60 second update interval by default
E.) 30 second updates interval by default
Ans A B D
CDP stands for Cisco Discovery Protocol. It is used to discover
directly connected neighbors, it is on by default and has a 60
second update interval by default.
176 Identify 2 transport layer protocols?
A.) IP
B.) TCP
C.) CDP
D.) ARP
E.) UDP
Ans B E
TPC and UDP are 2 layer4 Transport protocols.
177 Identify 2 features of X.25?
A.) Supports only IP
B.) Utilizes switched and permanent virtual circuits
C.) Contains minimal flow control and error recovery
D.) Utilizes LAPB as it's data-link protocol
Ans B D
X.25 utilizes LAPB and uses switched and permanent VC's. It
supports multiple layer protocols and is heavy laden with error
detection and correction mechanisms.
180 Identify the purpose of the Trace command?
A.) Explorer packet transmitting routing information
B.) Test connectivity
C.) Determine the path a packet is taking through the network
D.) Transmits user data when buffers are full
Ans C
The trace command is used to determine the path a packet has
taken through the network.
190 Identify the purpose of the TCP 3 step handshake?
A.) Setup a un-reliable connection
B.) Initialize routing tables
C.) Synchronize sequence numbers between hosts
D.) Connection tear down process
Ans C
The 3 step handshake establishes the parameters required for a
TCP connection. During the handshake process sequence numbers
are synchronized allowing for the end points to properly
acknowledge and re-assemble the segments.
