Refer to the exhibit.

The correct answer is B because Cisco Nexus 9000 switches that support NX-OS with Linux Bash shell require a two-step process when a feature is delivered as an RPM package. First, the feature must be installed at the Linux level using the Bash shell and the yum package manager. This is done with the command:

sudo yum -y install bgp

This step installs the necessary binaries and dependencies for the BGP feature. After installation, the feature is not automatically active in NX-OS. The second step is to enable the feature within NX-OS CLI using:

feature bgp

This activates the control plane functionality and allows configuration of BGP on the switch.

Option A is incorrect because it attempts to enable the feature before installing it. Option C is invalid because feature bgp cannot be executed in Bash mode. Option D is incorrect because yum commands must be executed in the Bash shell, not in NX-OS configuration mode.

Thus, the correct workflow is install via Bash → enable via NX-OS CLI, which is exactly what option B describes.
