• Question 482:

  SystemA has a file system named /data/dbase that is being shared. systemB needs to mount that file system so that users on systemB can access the data remotely on systemA. The information in the /data/ dbase file system is confidential and access to that data must be restricted so that only user1 and user2 can access the data from systemB.

  Which answer describes a method to protect the data on systemA so that only specific users on system can access that data?

  A. Share the file system on systemA as follows: share -F nfs -o rw=systemB /data/dbase. On systemB, mount the file system as follows: mount -F nfs -o hard,rw=user1,user2 \systemA:/data/dbase /data
  B. Share the file system on systemA as follows: share -F nfs -o rw=systemB:user1,user2 /data/dbase
  C. On systemA, protect the /data/dbase directory using conventional UNIX permissions so that only user1 and user2 can access the data.
  D. On systemA, protect the /data/dbase directory using conventional UNIX permissions so that only user1 and user2 can access the data. Then, share the file system on systemA as follows:
  D. On systemA, protect the /data/dbase directory using conventional UNIX permissions so that only user1 and user2 can access the data. Then, share the file system on systemA as follows:

  Rather than unmount the file system and make it unavailable during the backup, you want to create a point in time snapshot of the file system and backup that snapshot. Which command is used to create a point in time snapshot of the dbase file system?

  A. zfs clone data/dbase data/sdbase/dbase_snapshot
  B. zfs snapshot files/data data_snapshot
  C. fssnap -F ufs -o bs=/var/tmp /data/dbase /dev/fssnap/0
