• A.Sessions connected to the failed node could be relocated to one or more surviving nodes.
• B.The node is evicted from the cluster
• C.Cluster Resources running on the failed node are relocated to one or more surviving hub nodes.
• D.Cluster Resources running on the failed node are suspended until the node is restarted.
• E.Cluster resources running on the failed node must be recovered when the node is restarted.

Which three statements are true about diagnostic reporting for the OCR and OLR files? (Choose three.)

• A.The OCRCONFIG utilty can be used to repair a corrupt OCR file in an online fashion with the clusterware running on all nodes.
• B.The OCRCHECK utility can check the OLR in an online fashion with the clusterware running on all nodes.
• C.The OCRDUMP utility can dump specific keys from the OCR in an online fashion with the clusterware running on all nodes.
• D.The CLUVFY utility can check the integrity of the OCR but not the OLR.
• E.The OCRDUMP utility can dump specific keys from the OLR in an online fashion with the clusterware running on all nodes.

You administer a six-instance, policy-managed, multitenant RAC database CDB1 with three PDBs: PDB_1,PDB_2, and PDB_3.
Server pool prod_pool has a cardinality of three and all six hosts of the cluster are up.
Examine these commands executed on HOST01:

Which two statements are true regarding the AR service? (Choose two.)

• A.AR is available on any one available CDBl instance in prod pool at any one time.
• B.AR can fail over to any other available CDBl instance in prod pool.
• C.AR is available only on the CDBl instance on host01.
• D.AR runs as a singleton service in the server pool prod pool and the AR service is available in each of the CDBl instances.
• E.AR can fail over to any one of the available CD31 instances.

A Java application using thick JDBC connections will soon be deployed, and you must configure a RAC database to support highly available connections.
Broken connections must be re-established as quickly as possible.
Which feature will support this requirement?

• A.Fast Connection Failover (FCF)
• B.Transparent Application Failover (TAF)
• C.Fast Connection Failover (FCF) with Transparent Application Failover (TAF)
• D.Transparent Application Failover (TAF) using Fast Application Notification (FAN)

Which two statements are true about load balancing using a database service in a RAC environment? (Choose two.)

• A.In client-side load balancing, the SCAN listener uses the Load Balancing Advisory to direct a connection request to the least loaded instance hosting the service.
• B.Server-side connect time load balancing is done at the time of the initial connection attempt to the database service.
• C.Server-side load balancing connections are always distributed across instances based on the fastest response time for the service.
• D.Client-side connect time load balancing is done at the time of the initial connection attempt to the database service.
• E.Client-side connect time load balancing works only if it uses a tnsnames entry specifying load BALANCE=yes.
