問題 #1
Which two actions guarantee that time is synchronized properly on all nodes in a cluster after installing Oracle Grid Infrastructure 19c? (Choose two.)
A. If network time protocol (NTP) time servers are unreachable on any cluster node, then Oracle Cluster Time Synchronization Service (CTSSD) will start automatically in active mode when the clusterware is started.
B. Configure network time protocol (NTP) on all cluster nodes, and then start the Oracle Cluster Time Synchronization Service (CTSSD) in active mode on all cluster nodes.
C. If network time protocol (NJP) is not configured properly on all cluster nodes, then Oracle Cluster Time Synchronization Service (CTSSD) will start automatically in active mode when the clusterware is started.
D. Configure network time protocol (NTP) on all cluster nodes; Oracle Cluster Time Synchronization Service (CTSSD) will then start automatically in observer mode when the clusterware is started.
E. Deactivate network time protocol (NTP) on all cluster nodes; Oracle Cluster Time Synchronization Service (CTSSD) will then start automatically in active mode when the clusterware is started.
問題 #2
Which method should be used to convert a single-instance Oracle 19c Database to a RAC Database?
A. Using dbca to create a template from the single-instance database and then to create a RAC database on the cluster using that template
B. Using the rconfig utility to create a template from the single-instance database and then using dbca to create a RAC database on the cluster using that template
C. Using the rconfig utility to migrate the database to shared storage and then using dbca to start one or more RAC database instances on the cluster
D. Using dbca to migrate the database to shared storage and then to start one or more RAC database instances on the cluster
問題 #3

B. The OCRCONFIG utilty can be used to repair a corrupt OCR file in an online fashion with the clusterware running on all nodes.
C. The OCRDUMP utility can dump specific keys from the OLR in an online fashion with the clusterware running on all nodes.
D. The OCRDUMP utility can dump specific keys from the OCR in an online fashion with the clusterware running on all nodes.
E. The OCRCHECK utility can check the OLR in an online fashion with the clusterware running on all nodes.

D. When using Zero Downtime Patching, the root.sh script must be executed manually with -nodriver update option.
E. Zero Downtime Patching requires in-place patching of Oracle Grid Infrastructure 19c with Oracle RAC or Oracle RAC One Node databases of 19c or later releases and only the binaries in the Oracle Grid Infrastructure user space are patched.
問題 #5
