What information does a router running a link-state protocol use to build and maintain its topological database？ （）

A . The peer router immediately removes the BGP routers that it learned from the restarting router from itsBGP routing tables. B . The router establishes BGP sessions with other routers and relearns the BGP routes from others that are also capable of graceful restart. The restarting router waits to receive updates from the neighboringrouters. When the neighboring routers send end-of-RIB messages to indicate that they are donesending updates，the restarting router starts sending its own updates. C . The peer router sends an end-of-RIB message to the restarting router. D . The restarting router removes any stale prefixes after the timer for stale entries expires. E . The restarting router does not remove any stale prefixes after the timer for stale entries expires.

A . LSAs from other routers B . Beacons received on point-to-point links C . hello packets D . Routing tables received from neighbors E . SAP packets sent by other routers F . TTL packets from exclusive router

A . Stores data on the network and connects the local-area network (LAN) to the wide-area network (WAN) B . Routes traffic down alternative paths and connects the local-area network (LAN) to the wide- area network (WAN) C . Broadcasts data to all devices that are connected to it across the local-area network (LAN) and wide-area network (WAN) D . Reads Media Access Control (MAC) addresses to forward messages to the correct location and connects the local-area network (LAN) to the wide-area network (WAN)

A .  It allows you to get inter partition reports， or cross partition performance activity. B .  It will allow IBM remote technical support to get performance information from the machine. C .  It is effective only on POWER6 and when Live Partition Mobility operations are planned. D .  It will start standard performance monitoring tools when an LPAR boots up， the output will be saved to the /etc/perf directory by default.

A . hello packets B . SAP messages sent by other routers C . LSAs from other routers D . beacons received on point-to-point links E . routing tables received from other link-state routers F . TTL packets from designated router

A . RSSI of the client at the access point B . WMM state C . current MOS value D . current RF channel E . current transmit data rate

A . An IBM BladeCenter H chassis for the JS22 Blade servers B . A concurrent KVM daughter card C . A pair of IBM BladeCenter Power Supplies D . A second Management Module

A . It will abort the transmission and set off an audible alarm that must be manually reset B . It will initiate the DSC distress alert but，as no information will be transmitted，rescue personnel will not be able to identify the vessel，its position or its situation C . It will initiate the DSC distress alert and default information will automatically be transmitted D . It will initiate the DSC distress alert，but any station receiving it will have to establish contact with the distressed vessel to determine its identity，position and situatio

A . The peer router sends an end-of RIB message to the restarting router B . The peer router immediately removes the BGP routes that it learned from the restarting router from its BGP routing table C . The restarting router does not remove any stale prefixes after the timer for stale entries expires D . The router establishes BGP sessions with other routers and relearns the BGP routes from other routers that are also capable of graceful restart. The restarting router waits to receive updates from the neighboring routers. When the neighboring routers send end-of-RIB messages to indicate that they are done sending updates， the restarting router starts sending its own updates E . The restarting router removes any stale prefixes after the timer for stale entries expire
