문제3

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; Oracle Cluster Time Synchronization Service (CTSSD) will then start automatically in observer mode when the clusterware is started.

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, and then start the Oracle Cluster Time Synchronization Service (CTSSD) in active mode on all cluster nodes.

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.

정답: B,C
