A company has numerous LPARs hosting database servers, and three versions of the DBMS
deployed in the environment. A critical APAR fixes data corruption for one version of the database,
but it requires a server reboot. The only inventory information available is a spreadsheet with
every LPAR’s hostname and root password.
Which sequence of tasks will determine which servers are missing the critical APAR, and only
apply it to the servers running the affected level of the database?

A.
Use the spreadsheet to populate the /etc/hosts file on the management node.
Configure a NIM server that has the APAR in an lpp_source.
Force-register all of the LPARs with the NIM server.
Use NIM group operations to install the APAR and boot at a scheduled time.

B.
Use the spreadsheet to create a dsh node list.
Use dsh with Islpp to create a node list for LPARs needing the APAR.
Use dcp and dsh to install the APAR and reboot.

C.
Configure a Systems Director server using the spreadsheet import function.
Use the inventory function to discover the database level and APAR status.
Use the Update Manager to apply the APAR to the affected LPARs and reboot.

D.
Use the spreadsheet to create a dsh node list.
Use dcp and dsh to install the APAR.
Use dsh to reboot the systems.
