T or F: WANs affix nodes, such together workstations, servers, printers, and also other devices, in a small geographical area on a solitary network.

You are watching: Multiplexing enables a single t1 circuit to carry how many channels?


T or F: DSL services require many subscribers to share the same local line, leading to potential security concerns.


T or F: back MPLS have the right to operate end Ethernet frames, that is much more often supplied with various other Layer 2 protocols, prefer those designed because that WANs.


T or F: CDMA (Code division Multiple Access) is an open up standard that is accepted and used worldwide.


T or F: the word "synchronous" as provided in the name of Synchronous Optical Network way that data being transmitted and received through nodes should conform come a time scheme.


In an ISDN connection, what lot of throughput go a solitary B channel provide? 32 Kbps 48 Kbps 96 Kbps 64 Kbps


Which that the complying with is an benefit of leasing a frame relay circuit end leasing a committed circuit? You space guaranteed to receive the maximum amount of bandwidth stated in the circuit contract frame relay is a newly created network modern technology with more features than other technology. The courses that her data will certainly take are always known. Girlfriend pay just for the bandwidth girlfriend require.


The DTE or endpoint an equipment for a leased line is recognized as which machine below? DSL modem CSU/DSU ISDN modem cable modem


What OC level is generally used as a regional ISP backbone, and occasionally by very large hospitals, universities, or other major enterprises? OC-48 OC-12 OC-3 OC-96


The C-Band used by satellites is composed of what frequency range? 3.4 - 6.7 GHz 12 - 18 GHz 2.7 - 3.5 GHz 1.5 - 2.7 GHz


In subway settings, end-to-end, carrier-grade Ethernet networks can be created via what protocol? Intra-city Ethernet Ethernet SONET subway Carrier move Carrier Ethernet Transport


Which statement about the use of cable modems is not accurate? Cable modems just operate in ~ the physics layer the the OSI model. DOCSIS 3.1 enables for complete duplex increases to 10 Gbps. Cable broadband provides a specialized and consistent connection. Modems that utilize the DOCSIS 3.0 or 3.1 standard space backward compatible through older DOCSIS networks.


The T-carrier standards, likewise called T-CXR standards, utilize what form of multiplexing over 2 wire bag to develop multiple channels? wavelength division multiplexing (WDM) time division multiplexing (TDM) orthogonal frequency division multiplexing (OFDM) frequency department multiplexing (FDM)


On an ATM network, exactly how is the course that data will certainly take determined? Switches identify the optimal path in between sender and also receiver, and then establish the path before transmission. A frame relay path table creates each hop that will certainly be taken to a solitary destination. Data istransfer , and then the path taken will certainly vary depending on the load encountered at every ATM participant node. As soon as data is ready to be transmitted, an ATM participating router will call the destination ATM router, establish a tunnel, then happen the data.


Switches identify the optimal path between sender and receiver, and then establish the path before transmission.


What type of virtual circuit permits connections come be developed when parties need to transmit, climate terminated after ~ the infection is complete? permanent virtual circuit (PVC) looping virtual circuit (LVC) dynamic digital circuit (DVC) switched online circuit (SVC)


Which of the following Layer 1 WAN technologies is not normally used together last mile service, however rather traverses multiple ISP networks, connecting these networks to the internet backbone? T-carrier (T1s, spring T1s, and also T3s) SONET (Synchronous Optical Network) digital subscriber heat (DSL) Carrier-Ethernet move (CET)


Where are MPLS labels put within a frame? between the data payload and also the layer 2 trailer in ~ the finish of the layer 2 trailer in between the class 3 header and the data payload in between the layer 2 header and the great 3 header


What is a data-link connection identifier (DLCI) utilized for? it is provided by routers to create a packet-switched path to the destination. That is used by routers to identify which circuit to front a framework to in a framework relay network. It is offered by ATM switches to determine exactly how to develop a switched online circuit. The is a locally significant ID used to send connectionless information.


Which statement regarding the Asynchronous Transfer setting (ATM) an innovation is accurate? In ATM, a message is called a framework and always consists the 1500 bytes that data. ATM can carry out 4 level of QoS, from finest effort shipment to guaranteed, real-time transmission. ATM is a point-to-multipoint WAN access an innovation that provides packet switching. ATM is highly dependent on predetermined schemes that specify the timing of data transmissions.
