Which four statements are true concerning the upgrading of Oracle Grid Infrastructure 12c?
A.
The ORACLE_HOME environment variable must be set to the Grid Infrastructure home directory in the installation owner’s environment.
B.
The upgrade must be done in-place.
C.
The upgrade must be done out of place.
D.
Upgrade validation may be done using the Oracle Universal Installer which in turn invokes the built-in cluster verification utility.
E.
The cluster verification utility cluvfy.sh can verify that the cluster is ready for an upgrade.
F.
The ORACLE_SID environment variable must be set to the SID of the ASM instance in the installation owner’s environment.
G.
The cluster verification utility cluvfy.sh can generate fixup scripts to run on all nodes of the cluster.

for me it is c,d,e and g
I think a is wrong
Only out-of-place upgrades are supported because Oracle
Clusterware 12c must have its own, new Grid home.
———————
For each node, use Cluster Verification Utility to ensure that you have completed
preinstallation steps. It can generate fixup scripts to help you to prepare servers. In
addition, the installer will help you to ensure all required prerequisites are met.
———————
You can run upgrade validations in one of two ways:
– Run OUI, and allow the CVU validation built into OUI to perform system checks and generate fixup scripts.
– Run the CVU manual script cluvfy.sh to perform system
checks and generate fixup scripts.
I think also C,D,E,G,
I think that is “C”, “D”, “E” and “G”
“A” and “F” is wrong:

…
2. For the installation owner running the installation, if you have environment variables set for the existing installation, then unset the environment variables $ORACLE_HOME and $ORACLE_SID, as these environment variables are used during upgrade. For example:
$ unset ORACLE_BASE
$ unset ORACLE_HOME
$ unset ORACLE_SID
“B” is wrong too:
“All upgrades are out-of-place upgrades, meaning that the software binaries are placed in a different Grid home from the Grid home used for the prior release.”
Agree with C,D,E,G
