A field technician is installing a new Cisco Nexus switch in a data center. What type of physical connector is commonly used for high-speed, short-distance links (e.g., 10Gbps) between devices within the same rack, as an alternative to fiber optics?
Correct Answer: Twinax Direct Attach Cable (DAC) Explanation: Twinax (Twinaxial) Direct Attach Cables (DACs) are a cost-effective, low-latency, and low-power solution for short-reach, high-speed (e.g., 10GbE, 25GbE, 40GbE) interconnections within racks in data centers.
