Oracle Database Administration 2019 Certified Professional — Question 49

Which two steps must always be performed to delete node host04 from an Oracle 19c Clusterware cluster that does not use Grid Naming Service (GNS)? (Choose two.)

Answer options

• A. Run the crsctl unpin css - host04 command as root on host01, or on either host02 or host03.
• B. Run the crsctl delete node -n host04 command as root on host04.
• C. Run the crsctl delete node -n host04 command as root on host01, or on either host02 or host03.
• D. Run the crsct1 unpin css - host04 command as root on host04.
• E. Run the rootcrs.pl -deconfig -force command as root on host04.
• F. Run the rootcrs.pl -deconfig -force command as root on host01, or on either host02 or host03.

Correct answer: C, E

Explanation

The correct answer includes option C which involves executing the delete node command from a different host in the cluster, as you cannot delete a node from itself. Option E is also correct because deconfiguring the cluster must be done from a node other than the one being deleted, ensuring that the cluster remains operational during the process. The other options either attempt to delete the node from itself or use incorrect commands.
