多项选择题WhichthreestatementsbestdescribeHSRPconfigurationonCiscoNexusswitches？（）

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.

多项选择题WhichthreestatementsdescribeuserauthenticationinCiscoDCNM-LAN？（）

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.

多项选择题WhichthreestatementsabouttheDHCPsnoopingfeatureonCiscoNexusswitchesaretrue？（）

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.
