正解:A
Option A is the correct configuration to use the DNS server with IP address 192.168.1.1 on a Cisco UCS Fabric Interconnect. The engineer needs to scope the system settings, create a DNS entry with the IP address, and commit the buffer. The other options have incorrect commands or syntax errors. For example, option B uses the wrong command to set the name of the fabric interconnect, option C uses the wrong command to create the DNS entry, and option D uses the wrong command to scope the system settings.
