B: You can enable tracing for Oracle Clusterware resources by running the crsctl set trace command, using the following syntax: crsctl set trace module_name "component_name=tracing_level,..." C: The crsctl syntax to enable debugging for resources is: crsctl debug log res "resname:1" Incorrect Answers: A: Cluster Verification Utility (CVU) performs system checks in preparation for installation, patch updates, or other system changes. Using CVU ensures that you have completed the required system configuration and preinstallation steps so that your Oracle Grid Infrastructure or Oracle Real Application Clusters (Oracle RAC) installation, update, or patch operation, completes successfully. D: There is no USA_ORA_DEBUG environment variable. References: https://docs.oracle.com/cd/E11882_01/rac.112/e41959/crsref.htm#CWADD526
