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. The label bindings are kepton state information， which helps the failed node recover faster and does notaffect the current for wardtraffic. C . Graceful restart allows a node to recover state from its neighbor when there is no RP or before thedevice undergoes SSO. D . Graceful restart does not allow session information recovery. E . During a graceful restart， the router removes any stale prefixes after a timer for stale entries expire

A . NAT protects network security because private networks are not advertised. B . NAT accelerates the routing process because no modifications are made on the packets. C . Dynamic NAT facilitates connections from the outside of the network. D . NAT facilitates end-to-end communication when IPsec is enable. E . NAT eliminates the need to re-address all host that require extemal access. F . NAT conserves addresses through host MAC-level multiplexing.

A . creates a link between business and IT planning B . increases profitability C . increases customer loyalty D . lowers TCO
