Show Suggested Answer

Suggested Answer: D

Cisco NX-OS is the operating system specifically developed for Cisco Nexus series switches, which are widely used in modern data centers. NX-OS is optimized for scalability, high availability, and virtualization features.

It differs from IOS and IOS XE (used in traditional routers and switches) and IOS XR (used in carrier-grade platforms). NX-OS includes advanced features such as Virtual Port Channels (vPC), FabricPath, and integrated Layer 2/3 capabilities tailored for data center networks.

Hmm, I think it's B. IOS XE. Doesn't that cover the Nexus line too? Or am I getting my Cisco operating systems mixed up?

I'm pretty sure it's D. NX-OS. I mean, what else would power the Nexus series? IOS is for routers, not switches.

Definitely NX-OS. Cisco's Nexus line is built for the modern data center, and that's the operating system that powers it.
