 Understanding the Requirements:

The customer needs stackable switches that support Layer 2 functionality and Power over Ethernet (PoE).

 Switch Options:

A. CX 6400: High-end modular switch series, offering Layer 3 functionality but might be overkill for just Layer 2 and PoE requirements.

B. CX 6100: Entry-level switch series, may not offer the full stackable capabilities and PoE required.

C. CX 6200F: This specific model is not typically associated with PoE and stackable capabilities needed.

D. CX 6300: Stackable, Layer 2 switch with PoE support, making it a suitable choice.

 Why CX 6300 (D) is the Best Fit:

Stackability: The CX 6300 series supports stacking, allowing for scalable network deployments.

PoE Support: Provides Power over Ethernet, essential for powering devices like IP cameras and phones.

Layer 2 Functionality: Meets the requirement for Layer 2 network capabilities, making it a well-rounded choice.
