Routers in Internet Group Management Protocol (IGMP) use the
Protocol Independent Multicast (PIM) protocol to build
distribution trees. What happens once these trees are built? -
ANSWER-Constantly updated.
As part of multicast network management, what can notify
Simple Network Management Protocol (SNMP) network
management stations (NMS) of multicast problems and errors?
- ANSWER-Multicast traps.
Ray has logged into the corporate routers and configured open
shortest path first (OSPF) on each. Which of the following
addresses does OSPF use to multicast changes in the routing
tables? - ANSWER-224.0.0.6
Internet group management protocol (IGMP) is carried by which
protocol throughout a network? - ANSWER-Internet protocol -
IP
Which network type does intermediate system to intermediate
system (IS-IS) protocol support? - ANSWER-Usually, only one
router may represent a LAN to the other network.
,What is the primary purpose of the border gateway protocol -
BGP? - ANSWER-To avoid routing loops between large
networks.
For Carrier Ethernet, why is tagging packets
insufficient for bandwidth management? - ANSWER-Common
carriers receive and process trillions of packets from millions
of customers.
Which network connection has a relatively high cost, is billed
on a per port charge, and a rate per mile for the length of the
circuit? - ANSWER-Leased Lines
Which communication technique uses microwave frequencies?
- ANSWER-Satellite.
What is the oldest packet switching technology still in use
worldwide? - ANSWER-X25
What device is required to attach a non-integrated services
digital networks (ISDN) device to an ISDN network? - ANSWER-
Terminal Adapter
For any digital subscriber line (DSL) version, connection speed
depends on the customer's distance from the providers -
ANSWER-DSLAM - Digital subscriber line access multiplexer
,Which technology uses fixed-sized cells for transporting data?
- ANSWER-Asynchronous transfer mode (ATM).
What is an international standard for a high-speed, connection-
oriented, cell-
Switching technology? - ANSWER-Asynchronous transfer
mode (ATM).
Asynchronous transfer mode (ATM) virtual circuits (VC) switch
cells across networks by using which two header components?
- ANSWER-Virtual path identifier (VPI) and virtual channel
identifier (VCI).
In synchronous optical networks (SONET) and synchronous
digital hierarchy (SDH), how much faster is the data rate of an
electrical level STS-192 compared to
an STS-1? - ANSWER-192 times.
Tagging packets for prioritization is insufficient for Carrier
Ethernet. What is used instead of tagging? - ANSWER-
Hierarchical quality of service (HQoS).
Multiprotocol label switching - MPLS, compatible network
routers utilize label tags instead of which other element of a
data packet? - ANSWER-Internet protocol - IP address.
What is the most common digital standard for fixed telephony
devices? - ANSWER-Integrated Services digital network - ISDN.
, Which telephone system allows one extension to ring in
multiple locations, either at the same time or in sequence? -
ANSWER-Hosted PBX
The mapping of labels in a Multiprotocol label switching (MPLS)
network domain are maintained by which of the following? -
ANSWER-Label Forwarding Information Base (LFIB).
Ethernet over multiprotocol label switching (EoMPLS) is a
tunneling service, which transports _________ Ethernet frames
over an MPLS network. - ANSWER-Layer 2
What is the mandatory label in the label stack of the header in
time-division multiplexing over Internet protocol (TDMoIP)? -
ANSWER-Pseudo wire.
In a multiprotocol label switching (MPLS) network, which
network component pushes an MPLS label onto the front of an
incoming Internet protocol (IP) packet? - ANSWER-Label edge
router - LER.
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
DE capsulate and reassemble, MPLS needs to only do this. -
ANSWER-Add an additional header.
