（A）It runs automatically in Instance ADDM mode after each AWR snapshot is created.

（B）It can analyze performance over any given time period.

（C）It can analyze performance using data captured on all instances.

（D）It can diagnose skew in response time.

（E）It can only analyze performance on the instance running the ADDM job.

（F）It can diagnose latency problems in the Cluster Interconnect.

（A）When performing rolling patches, the vips for the node being patched are relocated to another node.

（B）When performing rolling patches, crsctl query crs softwareversion always displays the earliest version of the software running anywhere in the cluster.

（C）Some Grid Infrastructure patchsets may not be intalled in a rolling fashion.

（D）They can be applied in-place.

（A）It succeeds and 19c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST01.

（B）It succeeds and starts an ASM instance on HOST02 and shuts down the ASM instance on HOST03.

（C）It fails because the ASM instance has not been shut down first on HOST03.

（D）It succeeds and 19c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST02.

（E）It fails because an ASM instance is not configured to run on HOST02.

（F）It succeeds and starts an ASM instance on HOST02 but the ASM instance on HOST03 is not shut down until all connected clients disconnect.

（A）If network time protocol (NTP) time servers are unreachable on any cluster node, then Oracle Cluster Time Synchronization Service (CTSSD) will start automatically in active mode when the clusterware is started.

（B）Configure network time protocol (NTP) on all cluster nodes, and then start the Oracle Cluster Time Synchronization Service (CTSSD) in active mode on all cluster nodes.

（C）Configure network time protocol (NTP) on all cluster nodes; Oracle Cluster Time Synchronization Service (CTSSD) will then start automatically in observer mode when the clusterware is started.

（D）If network time protocol (NJP) is not configured properly on all cluster nodes, then Oracle Cluster Time Synchronization Service (CTSSD) will start automatically in active mode when the clusterware is started.

（E）Deactivate network time protocol (NTP) on all cluster nodes; Oracle Cluster Time Synchronization Service (CTSSD) will then start automatically in active mode when the clusterware is started.

（A）A server pool can be managed by QoS even if it does have database instances running on any server in the pool.

（B）Databases managed by QoS can be administrator managed or policy managed.

（C）It requires Oracle Grid Infrastructure for a Cluster to be installed and Clusterware to be running.

（D）It supports multiple databases assigned to the same server pool.

（E）It can manage database services only if they are defined as UNIFORM services.

（A）Using the rconfig utility to migrate the database to shared storage and then using dbca to start one or more RAC database instances on the cluster

（B）Using the rconfig utility to create a template from the single-instance database and then using dbca to create a RAC database on the cluster using that template

（C）Using dbca to migrate the database to shared storage and then to start one or more RAC database instances on the cluster

（D）Using dbca to create a template from the single-instance database and then to create a RAC database on the cluster using that template

（A）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.

（B）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.

（C）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.

（D）Zero Downtime Patching can be fully automated by selecting the option to automatically run the root.sh script.
