   A company is deploying Dell PowerEdge R750 servers in a data center with a raised floor. The servers will connect to a top-of-rack switch using 100GbE QSFP28 ports. The distance from the server to the switch is 3 meters. The company wants to minimize cost and power consumption. What is the best cabling choice?

   • AA 100G QSFP28 optical transceiver with OM4 multimode fiber
   • BA 100G QSFP28 active optical cable (AOC)
   • CA 100G QSFP28 to 4x25G SFP28 breakout cable
   • DA 100G QSFP28 passive direct-attach copper (DAC) cable

   A technician is cabling a new Dell PowerEdge R650 server in a rack with existing production servers. The server has two 10GbE SFP+ ports and two 1GbE RJ45 ports. The technician needs to connect the server to the top-of-rack switch for both management and data traffic. Which cabling approach best follows recommended best practices?

   • AConnect both 10GbE SFP+ ports to the switch and leave the 1GbE ports unconnected
   • BConnect both 1GbE RJ45 ports to the switch and use one 10GbE SFP+ port for a future uplink
   • CConnect one 10GbE SFP+ port for data and one 1GbE RJ45 port for management, labeling each cable at both ends
   • DConnect all four ports to the switch without labeling to save time
