What is the reason why this user is not able to enter configuration commands？（）
A. The user did not enter enable prior to going into configuration mode.

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.

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.
