A. IGMP is not synchronized between vPC peers
B. Cisco Fabric Service carries IGMP entries across the vPC peer link
C. IP ARP synchronization under the vPC domain configuration also synchronizes IGMP
D. IGMP is flooded to the L2 domain， and there is no need to synchronize it between vPC peers

A. The OTV control-plane protocol uses the IS-IS protocol to establish adjacencies and exchange MAC reachability across the overlay network. You must enable IS-IS with the feature isis command before OTV adjacencies can be established.
B. OTV uses an SSM group range for neighbor discovery and to exchange MAC reachability with other OTV edge peers.
C. The OTV join interface is a routed uplink interface on the edge device used to physically join the overlay network.
D. The OTV internal interface encapsulates the site Layer 2 frames in IP unicast or multicast packets that are then sent to the other sites.

D.Only show commands are supported via the XML management interface in NX-OS Software
E.The NX-OS implementation of the XML-based NETCONF requires SSH to be used for communication with the device

A. In a vPC topology， the primary HSRP router will respond to ARP requests， but both HSRP routers will forward data traffic. No additional configuration is required.
B. In a vPC topology， the primary HSRP router will respond to ARP requests， but both HSRP routers will forward data traffic if the peer-gateway feature is enabled.
C. You can configure two overlapping HSRP groups to load share traffic from the connected hosts while providing the default router redundancy.
D. You can use the show standby command to verify HSRP operation and configuration.
E. If you remove the feature hsrp command， all relevant HSRP configuration information isalso removed.

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. The user did not enter enable prior to going into configuration mode.
B. The software license installed on Nexus is Layer 2 only， which does not allow the creation of Layer 3 interfaces.
C. The user RBAC role is set to network-operator.
D. The user failed authentication and user access defaulted to read-only mode.
E. The AAA server is currently not responding.

A. Cisco DCNM-LAN server users are local to the Cisco DCNM-LAN server. Creating， changing， and removing Cisco DCNM-LAN server users has no effect on user accounts on managed devices.
B. A Cisco DCNM-LAN server user that has Administrator privileges can push out changes to managed devices even if the Cisco NX-OS role that is used on the discovered device has the network operator role.
C. Cisco DCNM-LAN user roles restrict the ability of users to make changes to Cisco DCNM-LAN server settings. Cisco NX-OS user roles enforce read/write privileges on the discovered devices.
D. Cisco DCNM-LAN allows you to configure unique credentials for each discovered device or use default credentials when you do not configure unique credentials for a device.
E. Cisco DCNM-LAN can use AAA servers to authenticate users. Only TACACS servers are supported.

A. DHCP snooping commands are not available until the feature is enabled with the feature dhcp- snooping command.
B. When you enable the DHCP snooping feature， the switch begins building and maintaining the DHCP snooping binding database.
C. The switch will not validate DHCP messages received or use the DHCP snooping binding database to validate subsequent requests from untrusted hosts until DHCP snooping is enabled globally and for each specific VLAN.
D. Globally disabling DHCP snooping removes all DHCP snooping configuration on the switch.
E. Globally disabling DHCP snooping does not remove any DHCP snooping configuration or the configuration of other features that are dependent upon the DHCP snooping feature.
