Refer to the exhibit. Which two VRFs does Cisco NX-OS create by default? (Choose two.)
The correct answer is A. default B. management. Cisco NX-OS automatically creates two VRFs by default: the 'default' VRF for regular data plane routing and the 'management' VRF for isolated out-of-band management traffic.

Why each option
Cisco NX-OS automatically creates two VRFs by default: the 'default' VRF for regular data plane routing and the 'management' VRF for isolated out-of-band management traffic.
The 'default' VRF is the primary and global routing table in Cisco NX-OS, where all interfaces are placed by default if not explicitly assigned to another VRF.
The 'management' VRF is a dedicated, separate routing instance created by default in Cisco NX-OS to isolate management traffic from regular data plane traffic, enhancing security and operational stability.
'PKA' is not a standard VRF created by default in Cisco NX-OS; it does not correspond to a known default routing instance.
'admin' is not a standard VRF created by default in Cisco NX-OS; while 'admin' is sometimes used for roles or specific contexts, it is not a default VRF name.
'global' is not a VRF name used by default in Cisco NX-OS; the equivalent concept for the main routing table is the 'default' VRF.
