Answer options

• D. multi-Layer refers specifically to using chassis switches with several line cards over stack port switches

Correct answer: C

Explanation

The correct answer, C, is accurate because a Multi-Layer Switch combines the functionalities of both Layer 2 and Layer 3 devices, enabling it to perform switching and routing. Option A is incorrect as Multi-Layer Switches do have Layer 1 features; option B focuses on specific features that do not define a Multi-Layer Switch; and D incorrectly describes the architecture of Multi-Layer Switches.
