Which three statements are true about the administration and use of policy sets in Oracle 12c Clusterware?

Question

Options

• AAll server pools in a cluster are controlled by the policy set, when user-defined policy
• BServers in a server pool outside the control of policy set are never affected by policy changes,
• CClusterware administrators cannot directly modify the policy set when Quality of Service
• DA server pool can have the same attributes defined for different policies in the policy set, when
• EA server pool can have different attributes defined for different policies in the policy set, when

• A
  80% (55)
• B
  14% (10)
• D
  6% (4)

Explanation

A: A cluster configuration policy set is a document that defines the names of all server pools configured for the cluster and definitions for all policies. C: If you create policies with Oracle Database Quality of Service Management (Oracle Database QoS Management), then you categorize servers by setting server pool directive overrides, and CRSCTL commands using the policy and policyset nouns are disabled. Note: Oracle Database 12c has introduced the policy sets, a feature that allows preparing in advance all the different workload scenarios and activating them with a single command. The easiest way to create policy sets is dumping the current configuration into a file, edit it, and reload it into the cluster. https://docs.oracle.com/database/121/CWADD/pbmgmt.htm#CWADD92635
