Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration Sample Questions:
Which two benefits are obtained by using Affinity to reduce global resource contention? (Choose two.)
- A. 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.
- B. 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.
- C. 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.
- D. 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.
- E. 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. High Redundancy ASM Disk Groups used for Clusterware files will contain two OCRs.

Which three statements are true about Quality of Service Management (QoS)? (Choose three.)
- A. A server pool can be managed by QoS even if it does have database instances running on any server in the pool.
- B. It can manage database services only if they are defined as UNIFORM services.
- C. It requires Oracle Grid Infrastructure for a Cluster to be installed and Clusterware to be running.
- D. Databases managed by QoS can be administrator managed or policy managed.
- E. It supports multiple databases assigned to the same server pool.
Correct Answer: C,D,E 🗳️
You want to create a tablespace, SALES, with these requirements:
1. Its data file has an alias name sales.dbf.
2. Its data file is stored in the directory CURRENT_YR in the disk group DATA.
Examine this command:
SQL> CREATE TABLESPACE sales;
Which two tasks must you perform to meet these requirements? (Choose two.)
- A. Create the current yr directory in the root directory (+).
- B. Add the autoextend on clause to the command.
- C. Add the DATAFILE '+DATA/CURRENT YR/sales.dbf clause to the command.
- D. Create the current yr directory in the +data disk group.
- E. lAdd the DATAFILE '/CURRENT YR/sales.dbf clause to the command.
Correct Answer: C,D 🗳️
You support a RAC database with these characteristics:
1. There are six instances.

5. Grid infrastructure is installed and running in its default configuration.
Which four benefits are provided by this configuration in Oracle 19c? (Choose four.)
- A. High availability for the ERP service
- B. Load balancing of connection requests across all six database instances
- C. Load balancing of client connection requests for CRM across four Single Client Access Name (SCAN) listeners
- D. Load balancing of client connection requests for ERP across three Single Client Access Name (SCAN) listeners
