Which action is required for the client currently mounting the rpool/expor/data file system to access the new data?

Your organization uses NFS to share data from Oracle Solaris servers to Oracle Solaris clients.
The server currently has an NFS share configured for the rpool/export/data file system. A client is
currently mounting this file system. As administrator, you add a new file system
rpool/export/data/yesterdays_data, and copy data into the new file system.

Explanation:

Note:
* In this Solaris release, you create a ZFS file system share and publish the share as follows:
Create the file system share and define the NFS or SMB share properties by using the zfs share
command.
* You can’t share a parent file system if a subdirectory or descendent file system is already
shared.
# share -F nfs /rpool/fs2/dir1
# share -F nfs /rpool/fs2/dir2
# share -F nfs /rpool/fs2
share: NFS: descendant of path is shared: /rpool/fs2/dir1 in rpool_fs2_dir2
