Examine this command: $ rhpctl move database `"sourcehome Oracle_home_path `"destinationhome Oracle_home_path For which two purposes can you use this command? (Choose two.)
A.
to switch an existing Oracle Database home to a newer release of Oracle software on the same server
B.
to switch to a read-only Oracle home
C.
to switch back to the previous Oracle home as part of a rollback operation
D.
to switch the Oracle Database home when using a centralized Rapid Home Provisioning server
Student Guide:
You can use rhpctl move gihome command with the same syntax to switch from the current Oracle Grid Infrastructure home to a patched home.
The rhpctl command enables you to switch from your current Oracle Grid Infrastructure or Oracle Database home to patched Oracle home so that you can provision the new Oracle home as gold image.
You can also use the rhpctl command to switch back to the old Oracle home, if you want to roll back the operation.
Correct Answer: CE
option A is incorrect and confusing..
Answer = C,E
True, A is incorrect.
student guide:
You can switch Oracle home and Oracle Grid infrastructure homes to later versions WITHOUT using a centralized Rapid Home Provisioning server.
E - Moves one or more databases from a source working copy or any Oracle Database home to a patched working copy.

C - think as backward of E
Answer is CE
A. False: if upgrading use "upgrade database"
B. True: "move database" checks for all patches present in current home are also present in new home, so the new home can be identical to the old home at patches level but can be read only.
C. False: to switch back use "-ignorewcpatches"
D. False: "move database" doesn't requiere a centralized Rapid Home Provisioning server
E. True: "move database" checks for all patches present in current home are also present in new home, but more patches can be present.
B seems correct. If both source and destination Oracle Home are read-only, I can't see any additional actions required.
C seems incorrect. You can switch the home but should not consider as "rollback" operation. You have to specify "-rollback" in the command, else some previous configuration files and parameters may not restored as part of "rollback" operation.
A. to switch an existing Oracle Database home to a newer release of Oracle software on the same server
Incorrect: Must be same database release level.
B. to switch to a read-only Oracle home
Incorrect
C. to switch back to the previous Oracle home as part of a rollback operation
May be correct for rhpctl but not with "rhpctl move database" May be with —revert parametr
D. to switch the Oracle Database home when using a centralized Rapid Home Provisioning server
Looks correct: This tool is Rapid Home Provisioning Control..so it's part of RHP Server..
E. to switch to a patched Oracle Database home
Absolutely correct from command base description.
DE
Use the rhpctl move database command to move one or more database homes to a working copy of the same database release level.
rhpctl is Rapid Home Provisioning Control..
So D is Correct
Why B is incorrect?
C is not completely correct since rolling back patches requires the -ignorewcpatches parameter which is not mentioned in the question
