A. Switch profiles allow configurations to be synchronized between switches and are supported with any Cisco NX-OS Software managed device.
B. DCNM LAN can archive configurations from devices even if they are not managed by the DCNM server， and the administrator can supply the device management IP address and credentials.
C. You can archive a maximum of 50 configuration versions per managed device.
D. Managed devices must be licensed in DCNM LAN before they can be used with configuration change management.
E. Device-running configuration will be archived only if it differs from the last archived version.

A. collecting the running configuration
B. raising the logging level to meet the minimum requirement
C. discovering all devices by default
D. discovering devices using multiple user accounts as long as they are administrator-level accounts
E. using LLDP to discover network adaptors

A. port security
B. fabric binding
C. IVR
D. port tracking
E. FICON

A.BPDUs that enter a blocking port are discarded.
B.BPDUs that enter a blocking port are processed.
C.Loopguard puts an interface into a loop-inconsistent state when BPDUs stop being received on a blocking port.
D.BPDUs are only processed on forwarding ports.

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.
