What are the two benefits of graceful restart？（）A、Graceful restart allows session information recovery without disruption to the network.B、A node can perform a graceful restart to help a neighbor recover its state.

Consistency checks and compatibility checks are performed before a Virtual PortChannel （vPC） is created. During a compatibility check， one vPC peer conveys configuration information to the other vPC peer in order to verify that vPC member ports can actually form a PortChannel. Which statements about a "Virtual PortChannel graceful consistent check" are true？（）A、 Graceful consistency check is enabled by default.B、 When graceful consistency check is enabled， only the links on the secondary peer device are suspended.C、 Graceful consistency check is disabled by default， so to enable this feature， use graceful consistency-check command under VPC domain configuration mode.D、 When graceful consistency check is enabled， only the inconsistent VLANs on the secondary peer device are suspended.

In which two ways does the BGP graceful capability preserve prefix information during a restart？（）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.
