Answer options

• A. Single mode fiber-optic cable
• B. Multi-mode fiber-optic cable

Correct answer: A

Explanation

AWS Direct Connect requires a physical connection over single-mode fiber-optic cable using either 1000BASE-LX (1 Gbps), 10GBASE-LR (10 Gbps), or 100GBASE-LR4 (100 Gbps) ports. Other connections like multi-mode fiber-optic or copper-based cables (twisted pair or shielded copper) are not supported for the direct physical link.
