Progression: Field Tech V -VI
Conventional
3-way calling - ANS-Allows parties to converse at the same time during session user can place
one of the parties on hold to speak to the other privately
A wire map field cable tester can include a time domain reflectometer (TDR) to determine the
distance to any breaks, shorts, or missed wires. In what situations can the tester be used? -
ANS-It is used to certify structured wiring in commercial buildings and can be used to verify
inside wire (IW) in residential settings.
According to Telecommunication Standardization Sector (ITU-T), what is a next-generation
network (NGN)? - ANS-A packet-based network.
According to Telecommunications Industry Association/Electronic Industries Alliance (TIA/EIA)
standards, which type of unshielded twisted-pair (UTP) cabling is recommended for data-grade
applications? - ANS-Category 5e.
ADSL - ANS-Operates over existing POTS lines, and is a digital switched non-packet-based
connection.
As part of multicast network management, what can notify Simple Network Management
Protocol (SNMP) network management stations (NMS) of multicast problems and errors? -
ANS-Multicast traps.
Asynchronous transfer mode (ATM) can be transported over multiprotocol label switching
(MPLS) networks and the reverse is also true. Looking at their individual attributes, where ATM
must segment and encapsulate data packets into cells and then decapsulate and reassemble,
MPLS needs to only do this. - ANS-Add an additional header.
Asynchronous transfer mode (ATM) virtual circuits (VC) switch cells across networks by using
which two header components? - ANS-Virtual path identifier (VPI) and virtual channel identifier
(VCI).
At work, Emily's laptop is assigned the Internet protocol (IP) address 192.10.10.10. When Emily
takes the computer home, the laptop is assigned the IP address of 192.168.100.25. Whether at
work or at home, what is the classful netmask assigned to her network interface card? -
ANS-255.255.255.0
Automated attendant - ANS-A virtual switchboard operator that directs incoming callers to
appropriate extension
Automatic call distribution - ANS-A process of distributing numerous incoming calls to a specific
group of terminals callers are greeted by an automated message that notifies them they will be
placed on hold until someone is available
Because a cable operator will support as many lines as technically possible for a business
customer, what does the installer have to do prior to connecting the embedded multimedia
terminal adapter (EMTA)? - ANS-Check the RF signal levels on the cable entering the building.
, Before a business telephone installation is performed in an office building, who must first
approve it? - ANS-The building owner or management company.
Before starting a final review with a customer at the end of an installation, what should an
installer try to do? - ANS-Talk to the same person that he or she spoke to at the beginning of the
installation.
Bruce purchased a replacement router/firewall combination machine to replace the old one he
inherited from the previous network administrator. The old router used decimal notation for
masks. The new router uses Classless Inter-Domain Routing (CIDR) notation for masks. Which
of the following decimal to CIDR notations are not valid? - ANS-255.255.255.0 to /32
Call block - ANS-Provides the ability to block select the types of incoming calls
Call forward - ANS-Allows customer to forward the phone to another phone number
Call return - ANS-Supplies the number of the last caller an option of automatically calling the
party back
Call screening - ANS-Automatically routes selected incoming numbers to a message that states
calls are not being accepted at this time
Call Transfer - ANS-Allows incoming calls to be transferred to either an external or internal
number
Call waiting - ANS-Notifies a telephone user another incoming calls waiting to be answered this
is typically provided by a short tone on the phone or by use of a caller ID feature
Caller ID - ANS-Notifies the telephone in use of the name or phone number of an incoming
caller
Challenge handshake protocol (CHAP) - ANS-The two endpoints use a challenge/response
authentication system.
Conference call - ANS-Links multiple parties into a single conversation
Ethernet over multiprotocol label switching (EoMPLS) is a tunneling service, which transports
_________ Ethernet frames over an MPLS network. - ANS-Layer 2.
For a business telephone installation, which of the following is the preferred location for the
embedded multimedia terminal adapter (EMTA)? - ANS-The main closet.
For any digital subscriber line (DSL) version, connection speed depends on the customer's
distance from the providers - ANS-Digital subscriber line access multiplexer (DSLAM).
For Carrier Ethernet, why is tagging packets insufficient for bandwidth management? -
ANS-Common carriers receive and process trillions of packets from millions of customers.
Frances connects her computer to the company's internal network, but she needs to access a
public search engine. What Application Layer (Layer 7) protocol can allow her private Internet
protocol (IP) address to connect to a public server? - ANS-Network address translation (NAT).
Full-duplex - ANS-Communication allows information to flow in both directions simultaneously
Grounding and protection are required in two places. One is in the equipment room or
telecommunications closet. Where is the other? - ANS-Building entrance.
Half-duplex - ANS-Communication takes place in both directions, but only in one direction at a
time.
Host identity protocol (HIP) - ANS-Allows for the separation of Internet protocol (IP) addresses
from the location function of the IP address when communicating on a virtual private network
(VPN) with a mobile device.
