Examine this sequence of commands:

The cluster consists of nodes HOST01, HOST02, HOST03 and HOST04, and the clusterware is running on all four nodes.
Which three statements are true about the result of the root user running these commands on HOST01? (Choose three.)

• A. The Oracle Clusterware stack is prevented from being automatically started on all nodes.
• B. The Oracle Clusterware stack is stopped on all nodes except host01.
• C. The Oracle Clusterware stack is started on all nodes.
• D. The Oracle Clusterware stack is prevented from being automatically started on host01.
• E. The Oracle Clusterware stack is started on all nodes except host01.
• F. The Oracle Clusterware stack is stopped on all nodes.

Which three statements are true regarding ASM on a four-node cluster? (Choose three.)

• A. A database instance on a node can only be a client of an ASM instance running on the same node.
• B. ASM Cluster File System (ACFS) can be deployed on any nodes.
• C. A database instance on a node cannot be a client of an ASM instance running on other nodes.
• D. A database instance on a node can be a client of an ASM instance running on any node.
• E. An ASM instance and database instances can coexist on the same node.
• F. A database instance on a node uses an ASM instance as an I/O server when requesting I/O to diskgroups.

Which three statements are true about the services created when the DBCA is used to create a RAC database? (Choose three.)

• A. A server pool must be created with srvct1 before creating a policy-managed RAC database that uses that server pool for a service.
• B. They can be policy managed for a multitenant database.
• C. Policy-managed services specified for a database allow the creation of a new server pool using dbca.
• D. They can be administrator managed for a multitenant database.
• E. Singleton services are not permitted for multitenant databases.

Examine this command:
SQL> CREATE PLUGGABLE DATABASE pdb3 FROM pdb1;
Which three conditions must be true for successful execution of this command on a RAC database? (Choose three.)

• A. It can be executed only by a common user with the create pluggable database system privilege connected to the root container.
• B. The source PD3 must be closed on the CDS instance from where the command is executed.
• C. Oracle Managed Files must be enabled or PD3 file name convert must be set.
• D. All running CDB instances must be open in restricted mode.
• E. The source pdb must use a global temporary
• F. The source PD3 must be in read only mode on all CD3 instances if the CDB is in No Archive mode.

Which two benefits are obtained by using Affinity to reduce global resource contention? (Choose two.)

• A. Oracle RAC affinity for partitioned tables routes all database requests for a partition tables to a single Oracle RAC instance leading to higher Oracle RAC performance and scalability because of improved cache locality and reduced internode synchronization and block pings of the partition tables.
• B. Oracle RAC affinity for partitioned tables routes database requests to all available Oracle RAC instances evenly to create a global affinity in such a way that each instance always gets an even number of requests leading to higher Oracle RAC performance by using a higher levels of available global cache to reduce global resource contention.
• C. Oracle RAC affinity for partitioned tables routes database requests to Oracle RAC instances in such a way that each instance always gets requests for a disjoint subset of rows in the database, this affinity leads to higher Oracle RAC performance and scalability because of improved cache locality and reduced internode synchronization and block pings.
• D. To enhance the performance of distributed transactions with applications server that provides XA affinity, you can automatically spawn new dedicated database RAC instances to isolate distributed transaction.
• E. To enhance the performance of distributed transactions with applications server that provides XA affinity, you can direct all branches of a distributed transaction to a single instance in the cluster to improve cache locality and reduce internode synchronization and block pings.
