Which three steps can be performed to determine the health of the OCR files and voting disks?

The Oracle Grid Infrastructure administrator wants to perform daily checks on the integrity of the
Clusterware files. Which three steps can be performed to determine the health of the OCR files
and voting disks?

A.
Run ocrcheck to verify the health of the OCR file only from the master node, which performs all
input/output (I/O) operations on the OCR.

B.
Run grep voting <grid_home>/log/<hostname>/cssd/ocssd.log from any cluster node.

C.
Run cluvfy comp ocr -n all from any cluster node.

D.
Run ocrcheck to verify the health of the OCR file from any cluster node.

E.
Run votecheck to verify the health of the voting disk from any cluster node.

Explanation:
Checking the Integrity of Oracle Clusterware
Configuration Files
The following techniques are used to validate the integrity of Oracle Cluster configuration files.
Check the ocssd.log for voting disks issues.
$ grep voting <grid_home>/log/<hostname>/cssd/ocssd.log
Use the cluvfy utility or the ocrcheck command to check the integrity of the OCR.
$ cluvfy comp ocr n all -verbose
$ ocrcheck
