Question

Which option is used as a top-of-rack device that is managed by its parent device, providing ease of management?

Options

ACisco Nexus 2000
BCisco Nexus 5000
CCisco Nexus 7000
DCisco Nexus 9000

Explanation

The Cisco Nexus 2000 Series is a Fabric Extender (FEX) designed specifically to be deployed as a top-of-rack (ToR) access layer device in data centers. It has no independent management plane; instead, it is fully managed by its parent switch (typically a Nexus 5000, 6000, or 7000), and appears as a virtual line card of that parent. This architecture simplifies management because administrators configure the parent switch rather than managing each Nexus 2000 independently. The Nexus 5000 (B), 7000 (C), and 9000 (D) are standalone, fully independent chassis-based switches that serve as aggregation or core devices.
