質問 2

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）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.

（D）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.

（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.

質問 3

Which statement describes the usage of Dynamic Service Fallback in Oracle RAC 19c?

（A）To enable Dynamic Service Fallback, you should specify the level of performance of a preferred instance for a service to be relocated to an available instance by setting the -fallback attribute of a service to "Low, Medium, or High".

（B）Dynamic Service Fallback allows a service to relocate to an available instance when the service is stopped on a preferred instance.

（C）Dynamic Service Fallback allows a service to fall back to a preferred instance when it becomes available after it was failed over to an available instance.

（D）Dynamic Service Fallback allows a service to fall back to a preferred instance when the available instance performance falls below a specified threshold after it was failed over to an available instance.

Your four-node cluster runs Oracle 19c Clusterware and supports a mix of RAC databases from Oracle 10g Release 2 to Oracle 19c.
All databases have one or more services defined.
The Oracle 10g Release 2 database clients connect to the database instances using the public VIP.
The Oracle 11g Release 2, 12c Release 1, and 19c clients connect to the database instances using the Single Client Access Name (SCAN).
You must change the public VIPs.
Which three actions must be performed to change the VIPs on host01, the first node in the cluster? (Choose three.)

（A）Use oifcfg setif to start the VIP on host01.

（B）Use srvctl modify nodeapps to change the VIP on host01.

（C）Use oifcfg setif to stop the VIP on host01.

（D）Use srvctl stop vip to stop the VIP on host01.

（E）Use srvctl start vip to start the VIP on host01.
