Which two additional steps are required when deleting a node from a cluster in this situation?

You plan to remove a node called RACNODE4 from a four-node cluster. The cluster is
running Oracle Grid Infrastructure 11g Release 2 and there is also a database home with
cluster databases running Oracle Database version 11g Release 1. This older home
supports different applications that have not been certified to run on the latest release. The
cluster databases for Oracle Database 11g Release 1 each had four Instances at one time,
but currently only the first two nodes, RACNODE1 and RACNODE2, are running instances
of those databases. Which two additional steps are required when deleting a node from a
cluster in this situation?

A.
Run olsnodes -t -n to list all cluster nodes that are pinned.

B.
Run crsctl nodelist -t -n to list all cluster nodes that are pinned.

C.
Run crsctl unpin css – RACNODE4 as the Grid Infrastructure owner if RACNODE4 is
pinned.

D.
Run crsctl pin css -n RACNODE1, RACNODE2 as root if the nodes are unpinned.

E.
Run crsctl pin css -n RACNODE4 as the Grid Infrastructure owner if RACNODE4 is
unpinned.

F.
Run crsctl unpin css – RACNODE4 as root if RACNODE 4 is pinned.
