CompTIA Network+ N10-009 Practice Question

Direct attach copper (DAC) cables are ideal for short-range, high-speed connections between network devices in scenarios like data centers. They are cost-effective compared to fiber optics and are specifically designed for distances typically up to 10 meters. On the other hand, Single-mode fiber, while capable of much longer distances, would be less cost-effective for this short-range requirement. Similarly, CAT6 cable supports up to 10 Gbps which might not meet high-speed requirements for inter-server connectivity in modern data centers. Coaxial cable, though it supports high frequencies, is generally not used for such connections in modern data centers.
