You work as a network administrator for Certkiller .com. During the first build of a new NIS map, the slave servers do not know of the map’s existence, so the push attempt fails. What can you do to recover from this problem?

A.
You transfer the source files from the NIS master to the NIS slave and execute a make on the NIS slave.

B.
You interrupt the build process with a CONTROL-C, and push all the mpas from the master server at once using the ypinit -s command.

C.
You put the build process into background processing mode, add an empty map to the slave server, and foreground the build process to continue the build.

D.
You interrupt the build process with a CONTROL-C when the push process hangs, and execute the ypxfr command on the map from one or more slave servers to complete the build process.
