Given this line from the name service configuration file:
        hosts: nis NOTFOUND=return] files

Which two statements correctly describe the behavior of the name service switch?   (Choose two)

A. If NIS were unavailable, the attempt to locate a hosts IP address would be abandoned.

B. If NIS were available but a host IP address was not in the NIS tables, the attempt to locate the hosts address would be abandoned.

C. If NIS where unavailable, the attempt to locate the hosts address would be continued within the local file (/etc/hosts).

D. If NIS were available but a host IP address was not in the NIS tables, the attempt to locate the hosts address would be continued by searching for it in the local file (/etc/hosts).
