Converges very quickly – from the point of recognizing a failure, it often can converge in less than 10seconds.? Supports VLSM.? Uses short Hello messages on a short regular interval, with the absence of hello messages indicating thata neighbor is no longer reachable.? Sends partial updates when link status changes, and floods full updates every 30 minutes. The flooding,however, does not happened all at once, so the overhead s minimal.? Uses cost for the metric.Reference:CCNA SelfStudy CCNA INTRO exam certification Guide (Ciscopress, ISBN 1587200945) Page 417QUESTION NO: 28As a network technician at TestKing you are configuring access lists on an interface of a Cisco router.You use multiple access lists.Which of the following statements are valid?
