• A.The ASM compatible attributes can be changed to 12. l for this disk group.
• B.It can contain ASM Dynamic Volume Manager (ADVM) volumes.
• C.Files created in this disk group always have two copies for each allocation unit: one primary and one secondary.
• D.Each disk in each of the three fail groups is a mirror of the corresponding disk of the other two failure groups.
• E.Any database instance with the COMPATIBLE parameter set to 12.2 or later can access it.

Your four-node cluster runs Oracle 19c Clusterware and supports a mix of RAC databases from Oracle 10g Release 2 to Oracle 19c.
All databases have one or more services defined.
The Oracle 10g Release 2 database clients connect to the database instances using the public VIP.
The Oracle 11g Release 2, 12c Release 1, and 19c clients connect to the database instances using the Single Client Access Name (SCAN).
You must change the public VIPs.
Which three actions must be performed to change the VIPs on host01, the first node in the cluster? (Choose three.)

• A.Use oifcfg setif to start the VIP on host01.
• B.Use srvctl stop vip to stop the VIP on host01.
• C.Use srvctl start vip to start the VIP on host01.
• D.Use srvctl modify nodeapps to change the VIP on host01.
• E.Use oifcfg setif to stop the VIP on host01.

Which three statements are true concerning activation of a user-defined policy in Oracle 19c Clusterware? (Choose three.)

• A.When a policy is activated, resources can be automatically stopped to comply with the policy definition.
• B.When a policy is first created, it is initially inactive.
• C.When a policy is activated, resources cannot be automatically started to comply with the policy definition.
• D.When a policy is first created, it is initially active.
• E.When a policy is activated, nodes may be reassigned to server pools based on the policy definition.
• F.An administrator-defined policy may be activated using the srvctl utility.

You administer a RAC database that currently runs on a four-node cluster but which has three instances.
Which two statements are always true about redo logs for this RAC database? (Choose two.)

• A.All the instances must have the same number of redo log groups and each group must have the same number of redo log members.
• B.A thread of redo must contain at least two log groups before it can be enabled.
• C.A redo log group added using alter database add logfile without the instance clause is added to each instance.
• D.A thread of redo is automatically dropped when an instance is removed from a RAC database by using SRVCTL.
• E.A thread of redo must be created before starting a fourth instance if a thread is not already available.
