141 LMI operates between the
Frame Switch and what other device?
A.) CPE device
B.) Another Frame Switch
C.) X.25 switch
D.) Novell File Server
Ans A
LMI stands for local management interface. It operates between
the Frame Relay switch and the customer equipment.
142 Identify IPX SAP and it's purpose?
A.) Sonet Access Pipe - interface to Sonet ring
B.) Service Advertising Protocol - advertise services
C.) Server Appletalk Protocol - appletalk directory services
D.) Service Access Point - identify upper layer protocols
Ans B
SAP is an Novell protocol to advertise services.
143 Identify the default values that make up IGRP's composite
metric?
A.) Bandwidth
B.) Load
C.) Reliability
D.) MTU
E.) Delay
Ans A E
IGRP can be configured to use all 5 within it's metric. By
default it uses bandwidth and delay.
144 Identify the default serial encapsulation?
A.) ISDN
B.) HDLC
C.) SDLC
D.) Frame Relay
E.) PPP
Ans B
The default serial encapsulation is HDLC.
145 Identify the purpose of ARP?
A.) Avoiding routing loops
B.) Determining a workstation's IP address
C.) Sending a directed broadcast
D.) Determining a workstation's MAC address
Ans D
ARP is used to find a devices MAC address given an IP address.
146 What is the purpose of the DLCI?
A.) Identifies the remote routers
B.) Contained with a 802.2 frame for routing purposes
C.) Used with PPP during authentication
D.) Identifies the PVC in a Frame Relay network
Ans D
DLCI stands for Data Link Connection Identifier. It identifies
the local PVC.
147 Identify 3 characteristics of the Network layer (OSI
layer 3)?
A.) Connection oriented
B.) Path determination
C.) Supports multiplexing
D.) Manages sessions
E.) Packet forwarding
Ans B C E
The network layer is responsible for routing which entails
learning the paths, selecting the best path and forwarding the
packet. Because it services multiple layer 4 protocols it
multiplexes.
148 Identify 3 characteristics of switches?
A.) Increase available bandwidth
B.) Decrease broadcast traffic
C.) Support full duplex in a multipoint topology
D.) Make forwarding decision using MAC address
E.) Create collision domains
Ans A D E
Switches operate at layer 2. They increase bandwidth by reducing
the number of devices sharing the media. They isolate
collisions. Like a bridge they forward traffic based upon layer
2 address/ MAC address.
149 Which OSI layer handles physical address, network
topology?
A.) Presentation
B.) Physical
C.) Transport
D.) Application
E.) Data-Link
F.) Network
Ans E
Layer 2 the Data-Link layer performs this function.
150 Identify 2 reasons for disabling CDP?
A.) If the router is not configured for RIP
B.) Save bandwidth by eliminating overhead
C.) If the router is configured for Appletalk
D.) When connected to a non-Cisco router
Ans B D
CDP can be disabled here are a couple of reasons. Connecting a
Cisco router to a non-Cisco router. Don't want to exchange CDP
information to save bandwidth.
