Which option provides software modularity in Cisco NX-OS software in the data center design?

Question

Options

• AThe ip routing command enables all of the features in the Cisco NX-OS.
• BAll of the features are enabled by default in the Cisco NX-OS.
• CIndividual features must be manually enabled to start the process.
• DThe Cisco NX-OS has a management VRF that is enabled by default.

• D

Explanation

Cisco NX-OS is built on a modular architecture where features run as separate processes. By default, most feature processes are not started, which reduces memory consumption, minimizes attack surface, and prevents unnecessary CPU usage. Administrators must explicitly enable each feature using the 'feature <name>' command (e.g., 'feature ospf', 'feature bgp') before it can be configured or used. This is fundamentally different from IOS, where most features are always available. Option A is incorrect-'ip routing' enables IP routing, not all features. Option B is wrong because NX-OS features are off by default. Option D is true (NX-OS does have a management VRF) but is unrelated to software modularity.
