When using Oracle 12 Clusterware, which two actions are required to repair the ocr.loc file on host01 in a
cluster having three other nodes called host02, host03, and host04?

A.
Run ocr.config –repair on another node in the cluster to repair the ocr.loc file on host01

B.
Stop the clusterware stack on host01 only.

C.
Stop the clusterware stack on all cluster nodes.

D.
Run ocrconfig –repair on host01.

E.
Stop the clusterware stack on host01 and on the node used to issue the ocrconfig –repair command.

Explanation:
B: You cannot repair the OCR configuration on a node on which the Oracle Cluster Ready Services daemon is
running.
D: When you repair OCR on a stopped node using ocrconfig -repair, you must provide the same OCR file name
(which should be case-sensitive) as the OCR file names on other nodes.
