Question

A network engineer is bringing up a new Cisco Nexus 9000 switch. During initial setup, the engineer assigns the mgmt0 interface an IP address and later notices that all management traffic to the device's mgmt0 interface is fully isolated from the data-plane routing table, even though no explicit VRF configuration was entered. Which statement correctly explains this behavior?

Accepted Answer

The mgmt0 interface is automatically placed in the dedicated 'management' VRF, isolating out-of-band traffic from the default routing table.

Answer

The mgmt0 interface uses a separate VDC by default, which prevents any communication with data-plane interfaces.

Answer

NX-OS applies an implicit ACL to mgmt0 that drops all traffic destined for data-plane subnets.

Answer

The mgmt0 interface operates in the default VRF but is placed in a private VLAN to enforce isolation.
