Progression: Field Tech IV - V
Conventional
_____ is a simple file transfer protocol used to transport data packets over UDP. - ANS-Trivial
File Transfer Protocol (TFTP)
________ allows network administrators to break up a single network address into smaller
network addresses, creating router-connected network segments, all with their own unique
network address space. - ANS-Subnetting
________ is an application that manages Internet resources and transmits them in response to
requests from Web browsers. - ANS-HTTP server
21. Which tagging method supports thousands of VLANs? - ANS-802.1Q
A Class 5 office connects individual subscribers to the telephone network and is also referred to
as: - ANS-End Office
Central Office
Local Office
A dedicated CO circuit that links two points is referred to as a: - ANS-Tie Line
A frame relay network uses fewer lines to connect 10 locations than a T1 mesh, and is therefore
more cost effective. True or False? - ANS-True
A line that goes from a customer's site through a CO to a remote CO in another part of the
country is known as a: - ANS-FX line
A NIC is a device used for: - ANS-Signaling
A Ping command uses which ICMP message types? (Choose three.) - ANS-Echo Reply
Source quench
Echo Request
A sound card is what general type of computer component? - ANS-Input/output
According to 10BaseT wiring rules, what is the maximum segment length without a repeater? -
ANS-100m
According to the North American Numbering Plan (NANP), what does the "803" in
803-550-0000 represent? - ANS-Number Plan Area
Admission control protocols, authentication mechanisms, and _______ are three ways
communication networks provide admission control. - ANS-Access Control Lists (ACLs)
After entering "arp" into the MS-DOS command line, which of the following switches would
display the ARP cache? - ANS--a or -g
An Application Layer process needs to transmit data with as little overhead as possible. The
application protocol provides error detection and recovery if the data is lost. What Transport
Layer protocol should this process use? - ANS-User Datagram Protocol
An Application Layer utility transmits network administration and control messages between
nodes. It must not use any more of the network's bandwidth than absolutely necessary. If
, messages are corrupted or lost, the utility handles retransmission, so it doesn't need this service
from the lower layers. This application should use the services of: - ANS-UDP
An Ethernet LAN that uses UTP cabling and a hub as the physical medium is referred to as
which of the following? - ANS-Star
An MG consists of which two components? (Choose two.) - ANS-Connections
Endpoints
Analog signals on copper cable can be distorted by: - ANS-Magnetic fields
Alternating current fields
Radio waves
At what OSI model layer does DiffServ operate? - ANS-Layer 3
At what point does end-to-end delay in a voice conversation become unacceptable? -
ANS-When it approaches 500 ms
At which OSI layer do bridges operate? - ANS-Data Link Layer
At which OSI layer do routers operate? - ANS-Network Layer
At which OSI layer do switches reside? - ANS-Data Link Layer
At which points in a one-way, multiple hop, end-to-end IP communications session will a frame
have to be built? (Choose two.) - ANS-At the sending host's LAN port
At each hop's router outbound port
ATM requires fiber media to run. True or False? - ANS-False
Bridges and Layer 2 switches filter traffic in which way? - ANS-By evaluating the destination
MAC address in each frame and switching each frame to the port that leads to the destination
frame address
Bridges are needed in which of the following situations? - ANS-Too much traffic on the LAN
Remote connection of two LANs over a WAN link
Can switches switch two frames simultaneously? - ANS-yes
Carrier sense multiple access with collision detection (CSMA/CD) is most like which of the
following? - ANS-An informal conversation in which each person speaks when the opportunity
presents itself, but only one person speaks at any time
Central offices are connected to which of the following - ANS-Class 4 offices
Other central offices
Individual subscribers
Collisions are normal on CSMA/CD LANs and not usually the result of errors. True or False? -
ANS-True
Curiosity, malice, and toll fraud are a few types of security problems that this service is
vulnerable to? - ANS-Voice mail
Data security, data compression, and ________ are the three main services that the
Presentation Layer provides. - ANS-Data representation
Each wire of a local loop is sometimes referred to as: - ANS-Tip and Ring
Encapsulation and protocol headers, decapsulation, and reassembly are three of the four basic
techniques used whenever different layers of protocols work together. What is the fourth? -
ANS-Segmentation
Ethernet operates at all speeds except which of the following? - ANS-16 Kbps
Forwarding, Learning, and _______ are three important functions provided by a bridge. -
ANS-Filtering
