Which two tasks does the Dynamic Host Configuration Protocol perform?（）

A . When loading selected rows into each table. B . When loading data from an export dump file. C . When loading data from disk， tape， or named pipes. D . When your data is NOT being inserted from a flat file. E . When using a record management system to access data files.

A . It provides dynamic neighbor discovery. B . It detects unreachable neighbors in 90 second intervals. C . It maintains neighbor relationships. D . It negotiates correctness parameters between neighboring interfaces. E . It uses timers to elect the router with the fastest links as the designated router. F . It broadcasts hello packets throughout the internetwork to discover all routers that are running OSPF

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.
