Which three statements are true about Quality of Service Management (QoS)?

Question

Options

• AA server-pool can be managed by QoS even if it does have database instances running on nay
• BIt can manage database services only if they are defined as UNIFORM services.
• CIt requires Oracle Grid Infrastructure for a Cluster to be installed and Clusterware to be running.
• DIt supports multiple databases assigned to the same server pool.
• EDatabases managed by QoS can be administrator managed or policy managed.

• A
  15% (4)
• B
  74% (20)
• E
  11% (3)

Explanation

B: Database services should be created as UNIFORM services, meaning the service is offered by every available instance running in the specified server pool. If your application requires a SINGLETON service, then, to use Oracle Database QoS Management in management mode, the service must run in a server pool that has a maximum size of one. If you use a SINGLETON service in a server pool that has a maximum size greater than one, then Oracle Database QoS Management reports a configuration violation. C: Initial QoS configuration includes: Installing and Configuring Oracle Grid Infrastructure for a Cluster Creating and Configuring Server Pools Creating and Configuring an Oracle RAC Database Enabling Oracle Database QoS Management Incorrect Answers: E: It must be policy managed. When you use DBCA to create an Oracle RAC database, you select policy-managed for the database, and choose the server pools which the database instances should run in. https://docs.oracle.com/cd/E11882_01/server.112/e24611/install_config.htm#APQOS157 https://docs.oracle.com/database/121/APQOS/wlm_strats.htm#APQOS341
