BIOS XE

CIOS XR

DNX-OS

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.

I thought IOS was the main OS for Cisco devices, but I guess NX-OS is more tailored for data centers?

Easy one - the Nexus series uses NX-OS, which is Cisco's data center-optimized operating system. I've worked with Nexus switches before, so I'm confident that's the right answer.

I'm a little confused on the differences between IOS, IOS XE, and IOS XR. I'll have to review those before the exam to make sure I understand which one is used for the Nexus series.

NX-OS is the answer. The question specifically mentions the Nexus series, and NX-OS is Cisco's operating system designed for their Nexus data center switches.

Hmm, I'm a bit unsure on this one. I know IOS is the standard Cisco operating system, but I'm not sure if that applies to the Nexus line. Let me think this through.

D. NX-OS. Easy peasy. Although I do wonder if the question is a trick, like 'Which OS powers the Nexus series of toasters?'
