Zero Downtime Patching uses Fleet Patching and Provisioning to patch Oracle Grid Infrastructure without bringing down Oracle RAC database instances.
Which three statements are true about Zero-Downtime Oracle Grid Infrastructure Patching? (Choose three.)

• A.Zero Downtime Patching can be fully automated by selecting the option to automatically run the root.sh script.
• B.Zero Downtime Patching requires out-of-place patching of Oracle Grid Infrastructure 19c with Oracle RAC or Oracle RAC One Node databases of 19c or later releases and only the binaries in the Oracle Grid Infrastructure user space are patched.
• C.When using Zero Downtime Patching, the root.sh script must be executed manually with -nodriver update option.
• D.Zero Downtime Patching requires in-place patching of Oracle Grid Infrastructure 19c with Oracle RAC or Oracle RAC One Node databases of 19c or later releases and only the binaries in the Oracle Grid Infrastructure user space are patched.
• E.When using Zero Downtime Patching, Oracle Grid Infrastructure OS system software, kernel modules and system commands including ACFS, AFD, OLFS, and OKA are not updated.

Which two statements are true concerning Oracle 19c Clusterware-managed application VIPs? (Choose two.)

• A.An application VIP is created on the default network by the appvipcfg utility.
• B.If an application sends messages to be displayed and sets the display variable, then an application VIP is required.
• C.An application VIP can be created with the crsccl utility.
• D.Application VIPs do not fail over to surviving cluster nodes when the node hosting the VIP fails.
• E.An application VIP is created on the interconnect network by the crsccl utility.

Examine the output of the asmcmd and srvctl commands:

Then you execute this command:
$ srvctl relocate asm -currentnode host03 -targetnode host02
Which three statements are true regarding the execution of this command based on the output shown? (Choose three.)

• A.It succeeds and starts an ASM instance on HOST02 but the ASM instance on HOST03 is not shut down until all connected clients disconnect.
• B.It succeeds and starts an ASM instance on HOST02 and shuts down the ASM instance on HOST03.
• C.It succeeds and 19c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST01.
• D.It fails because the ASM instance has not been shut down first on HOST03.
• E.It fails because an ASM instance is not configured to run on HOST02.
• F.It succeeds and 19c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST02.

A Java application using thick JDBC connections will soon be deployed, and you must configure a RAC database to support highly available connections.
Broken connections must be re-established as quickly as possible.
Which feature will support this requirement?

• A.Transparent Application Failover (TAF) using Fast Application Notification (FAN)
• B.Fast Connection Failover (FCF)
• C.Fast Connection Failover (FCF) with Transparent Application Failover (TAF)
• D.Transparent Application Failover (TAF)

Which two statements are true about v$asm- views in a clustered environment? (Choose two.)

• A.Their names can be seen in v$fixed_table when connected to an instance of any type that is started.
• B.They exist in both ASM and RDBMS instances, and display the same output.
• C.gv$asm_attribute can be used to display the ASM_POWER_LIMIT attribute of all ASM instances in the cluster.
• D.Their names can be seen in dice when connected to an ASM instance.
• E.They exist in both ASM and RDBMS instances, but they can display different outputs depending on the instance type.
