• A.Client-side connect-time load balancing can balance connection requests across SCAN listeners.
• B.Services support the balancing of client connections across RAC database instances.
• C.Load balancing can be done by the client or the listener, but not both, for any one connection request.
• D.In server-side load balancing, node listener redirects the client to another node listener for connection to an instance.
• E.Load balancing can be done by the client, the listener, or both, for any one connection request.

• A.A database instance on a node cannot be a client of an ASM instance running on other nodes.
• B.An ASM instance and database instances can coexist on the same node.
• C.A database instance on a node can be a client of an ASM instance running on any node.
• D.ASM Cluster File System (ACFS) can be deployed on any nodes.
• E.A database instance on a node uses an ASM instance as an I/O server when requesting I/O to diskgroups.
• F.A database instance on a node can only be a client of an ASM instance running on the same node.

Which three statements are true about the Global Resource Directory (GRD) in Oracle 19c RAC database and in Clustered ASM? (Choose three.)

• A.Clustered ASM has GRD resources distributed among all ASM instances.
• B.Shadow GRD resources may exist in more than one database instance for a resource.
• C.RAC databases have GRD cache resources distributed among all the database instances and stored in the large pool of each instance.
• D.RAC databases have GRD cache resources distributed among all the database instances and stored in the shared pool of each instance.
• E.All GRD Enqueue Resource master metadata is held in the large pool of the same database instance.
• F.Only one GRD shadow resource may exist for an Enqueue Resource.
• G.All GRD Enqueue Resource master metadata is held in the shared pool of the same database instance.

• B.acfsutil audit init must be run by a system administrator.
• C.Audit information gathered by each cluster node can be consolidated into the unified ACFS audit trail.
• D.acfsutil audit read marks audit files to indicate that it is safe to purge them.

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.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.
• B.Zero Downtime Patching can be fully automated by selecting the option to automatically run the root.sh script.
• C.When using Zero Downtime Patching, the root.sh script must be executed manually with -nodriver update option.
• D.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.
• E.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.
