The Tricounty Bridge was supposed to relieve traffic in East Countway County. Although the bridge was opened last year, traffic in the county has gotten worse over the last year. To relieve the traffic situation in East Countway, therefore, the traffic commission should order the Tricounty Bridge closed. Which of the following, if true, gives the most support to the conclusion of the passage above?
A
The increased traffic seen in East Countway over the last year is largely attributable to a large casino and resort hotel that opened for business shortly after the opening of the Tricounty Bridge.
B
The Tricounty Bridge allows inhabitants of heavily populated West Countway County to reach East Countway in less than a half-hour, as opposed to the two hours the trip required before the opening of the bridge.
C
The bridge is only open for the periods 7-9 a. m. and 3-5 p.m. on weekdays.
D
Ship captains on the Countway River have complained that the bridge disrupts shipping on the river, thereby hurting the local economy.
E
The bridge is unlikely ever to pay for itself with the current low toll payment.

解析：
文段的结论为因为新建的大桥加大了东部的交通压力，所以应该关闭大桥，B项提供了东部地区交通压力增加的一个可能的解释，即大桥的开通使得西部的军民到东部更加容易，故本题选B项。

MS-SPRing traffic is rerouted from the first in the ring.B、 SNCP traffic is selected at the destination node in the ring. MS-SPRing is rerouted from the originating node in the ring.C、 SNCP traffic is rerouted from the originating node in the ring.

Which three QoS mechanisms can be configured to improve VoIP quality on a converged network？（）A、The use of a queuing method that will give VoIP traffic strict priority over other traffic B、The use of RTP header compression for the VoIP traffic.C、The proper classification and marking of the traffic as close to the source as possibleD、The use of 802.1QinQ trunking for VoIP trafficE、The use of WRED for the VoIP traffic
Which two statements about WRED are true？ （）A、WRED can selectively discard lower priority traffic when the interface becomes congested and can provide differentiated performance characteristics for different classes of service.B、Resource Reservation Protocol （RSVP） and WRED cannot be configured on the same interface.C、WRED will throttle back voice traffic only as a last resort.D、If the average queue length is greater than the minimum threshold but less than the maximum threshold， then based on the drop probability， WRED will either queue the packet or perform a random drop.E、WRED statistically drops more packets from low-bandwidth users than high-bandwidth users.

An expanding company is deploying leased lines between its main site and two remote sites. The bandwidth of the leased lines is 128kb/s each， terminated on different serial interfaces on the main router. These links are used for combined VOIP and data traffic.
