Question # 1 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 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.C. 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.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.

Question # 4 Which three statements are true about ASM Cloud File System (ACFS) replication? (Choose three.) A. Replication is automatically terminated if the primary file system has less than 2 GB free space.B. ACFS auditing information is replicated from the primary file system to the standby file system.C. Standby redo log files are required on the standby site for synchronous redo transport.D. The privilege sysrepl has been introduced for ACFS replication.E. One site of an ACFS replication configuration can host both primary and standby file systems.
