CompTIA Server+ SK0-005 Practice Question

During a data-center expansion, a systems administrator is installing a rack-mount server whose NIC exposes two QSFP+ ports. The server must connect to a top-of-rack 40 GbE switch located about 2 m away in the same cabinet. Management wants the lowest-cost, lowest-power cabling that still delivers full 40 Gbps throughput. Which cabling solution should the administrator deploy?

  • Single-mode duplex LC fiber with QSFP-40G-LR4 transceivers

  • Passive QSFP+ direct-attach twinax copper cable

  • OM4 multimode MPO fiber with QSFP-40G-SR4 transceivers

  • QSFP+ active optical cable (AOC) rated for up to 100 m
