Which statement is true concerning the installation of an Oracle Grid Infrastructure 12c patchset and its status during the installation?
A.
Some grid infrastructure patchsets may not be installed in a rolling fashion.
B.
They can be applied in-place.
C.
When performing rolling patches, crsctl query crs softwareversion always displays the lowest version of the software running anywhere in the cluster
D.
When performing rolling patches, the VIPs for the node being patched are relocated to another node.
Explanation:
To check the software versions on a single node or if the software version is the latest version installed in on a cluster.
You would use this option when you do the rolling upgrade.
$ crsctl query crs softwareversion [hostname]

C CORRECT
When a rolling patch or upgrade is being performed, two versions of the software will
temporarily coexist in the cluster. The software version is the latest version that is installed on an individual node. You can check the software version registered in the OCR with the following command:
$ crsctl query crs softwareversion
Oracle Clusterware version on node [host01] is [11.1.0.7.0]
The active version is the lowest version anywhere in the cluster. It applies to the cluster and not an individual node. The active version is not updated until the last node has been updated to the newest version. You can check the active version with the following command:
$ crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [11.1.0.6.0]
C is defenetally wrong. “activeversion ” shows the lowest version.
I will go for D
A is wrong: For Oracle 12c All Patchset for GI are rolling fashion
B is wrong: Patchset for GI cannot be applied in-place
C is wrong: activeversion shows the lowest version on the cluster.
Yes, you are right, -> D
There is a trick here, activeversion x softwareversion in option C
