A user of a settlement telephone picks up her phone and establishs a telephone allure to a friend's settlement telephone in another dissect of town. Which of the aftercited is slight to be penny environing this allure? A. It uses a unmarried couple of wires on the topical loop at each end of the allure 2. Which of the aftercited are utilitys that telcos bear offered as WAN utilitys aggravate the years? A. Switched analog circumferences B. Dedicated digital circumferences 3. This stipulation claims that IP routers result polite as devices that coalesce to manifold incongruous expressions of interfaces, including LANs and WANS.
Which of the aftercited answers schedule the reasons why routers do polite in this role? A. Routers bear fur faster CPUs and can do the dense result to transfer the incoming factsintegrate header into the outgoing facts-integrate format D. Routers misconsider old facts-integrate headers and extort new facts-integrate headers as dissect of their logic, which treats each Interfaces lower-layer detallds as Independent from each other 4. An achievement netresult has manifold routers that coalesce to twain a LAN as polite as the WAN. Which of the aftercited statements best delineate how routers typically use and judge environing their WAN coalesceions?
B. As a bliss utility to give-up IP packets to the direct Ip router 5. An achievement builds a WAN pur-pose on tractate. The deep top, where all the servers sit, is shown in the life ofa netresult diagram. The WAN has a leased succession from that top to perfect unrelated top, delay the unrelated tops drawn encircling the edges of the guile In a big foe. None of the unrelated tops bear a leased succession promptly among them. Which of the aftercited conditions is most typically used to delineate this WAN topology? D. Hub-and-spoke 6. A U. S. fixed society wants to apapex a leased succession among two tops, delay the eased succession using the transmitted T-carrier DSO, DSI, and DS3 expressions of successions. Which of the aftercited answers delineates the hasten and interspaces for the leased succession? A. No faster than 43,736 Mbps (T3) D. No verbal interspace Ilmltatlon 7. A telco customer has purchased a Tl leased succession among two tops. The customer has alresponsive bought a router for one top, delay a serial interface card delay a built-in CSU/DSU. Which of the aftercited answers schedules other tangible dissects that the customer conciliate deficiency for that tops installation of the Tl leased succession?
B. A serial cable 8. A telco customer has a Tl leased succession among two tops, allureed tops A and B. he telco has divers switches among tops A and B that use T3 stocks. These switches use the T3 stocks along delay duration-division multiplexing (TDM) to educe the leased succession from top A to B. which of the aftercited answers is penny environing how TDM results in this pur-pose? C. The switches map the Tl customer successions to one of 28 incongruous frequencies in the T3 stocks 9. A telco netresult has TDM switches in the CO, responsive to patronage Tl leased successions to customer tops.
Two such switches bear a unmarried T3 stock coalesceing the two switches, set secret to patronage T Is that run Just among those two co swltcnes. nlcn 0T tne Tollowlng answers Dest aescrlDes tne numDer 0T customer T Is the telco can patronage delay these switches and the stock? C. 28 10. A customer appointed a liberal Tl leased succession among two tops. The telco implemented that leased succession in its netresult using the T-carrier technology discussed in this stipulation, delay DSI, DS2, and DS3 successions plus switches that use duration-division multiplexing (TDM) logic.
Into which of the aftercited unconcealed WAN categories does this utility fit? B. Packet switching 1 1 . A telco customer appoints a leased succession among tops A and B, delay requested hasten of 1. 024 Mbps. The customer plans to use an visible CSU/DSU at each top. The telco uses barely T-carrier technology and none of the past new-fangled options love SONET, ATM, MPLS, or Metro Ethernet. Which of the aftercited answers is penny environing the hastens used on this integrate? B. The tangible succession among the telco CO and top B uses a succession hasten of 1. 2544 Mbps 12.
A telco customer appoints a leased succession among tops A and B, delay requested hasten of 512 Kbps. The customer plans to use an visible CSU/DSU at each top. The telco uses barely T-carrier technology and none of the past new-fangled options love SONET, ATM, MPLS, or Metro Ethernet. Which of the aftercited answers is penny environing the hastens used among the router and the CSU/ DSU? A. THe CSU/DSU controls the router's transmiting and receiving hastens using clocking 13. Which of the aftercited answers are penny environing DSI framing and channels? A. Each fabricate has 193 bits C.
The fabricate groups 8 bits unitedly for each of 24 channels, plus aggravatehead 14. Which of the aftercited facts-integrate protocols was educed to be used on leased successions, delay patronage for multiple Layer 3 protocols by including a Expression scope that identifies the expression of packet delayin the facts-integrate fabricate? C. PPP 15. Which scopes that hold in twain the HDLC and PPP headers bear such proportionately inferior use in apex-to-apex leased successions today, to the apex that the PPP standards in-fact allows the nodes to simply not twainer to include these scopes when transmiting PPP fabricates?
B. Harangue C. Control 16. Judge environing the differences in a circumference switching the T-carrier regularity (by analog circumference switching) versus packet switching. Which of the aftercited answers are penny environing packet switching, but not environing circumference switching? B. The telco switch can queue the facts intermission on the congested outgoing to stock to grace adapted D. The switches appear at the bits to experience an harangue, and use that harangue to establish a select where to transmit the bits 17.
In a Fabricate Relay network, which of the aftercited conditions refers to the customer router that coalesces to the Fabricate Relay network? D. Access integrate 18. Which of the aftercited answers is not penny environing a Fabricate Relay network? B. Defined by the telco forward of duration, when the customers appoints the utility 19. A new Fabricate Relay customer is because two competing Fabricate Relay pur-pose for his WAN. One pur-pose uses a liberal-involution topology of PVCs among the 20 routers. The prevent pur-pose uses a dissectial involution that appears love a hub-and-spoke pur-pose.
Assuming that all other technical details not mentioned in this scrutiny are the similar when comparing the two pur-poses, which of these answers are penny environing the dissectial-involution pur-pose but not penny environing the liberal-involution pur-pose? A. Not all routers can transmit a Fabricate Relay fabricate alrectly to eacnotner B Fabricate Relay Trames, wlll De Torwaraea Dy tne netresult Dasea on the DLCI scope in the Fabricate Relay 20. Which two of the aftercited WAN utilitys establish amiable use of protocols that achievement bear used for manifold years, delay those protocols life remote and enhanced to educe new expressions of WAN utilitys?
