Secure Cluster Communication protects the cluster interconnect from common security threats when used together with Single Network Support. Secure Cluster Communication includes message digest mechanisms, protection against fuzzing, and uses Transport Layer Security (TLS) to provide privacy and data integrity between the cluster members.
Which statement is true about securing cluster interconnect communication?

• A.Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c using an auto-generated encryption key that is stored locally on each node of the cluster in an Oracle Wallet and Database administrators or cluster administrators must provide a valid path for the Wallet file.
• B.Security for the cluster interconnect is invoked by auto-generated server certificates that will be assigned to each cluster node as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c.
• C.Database administrators or cluster administrators must provide a valid server certificate and an Oracle Wallet for each node during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.
• D.Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c and Database administrators or cluster administrators do not need to make any configuration changes for this feature.
• E.Database administrators or cluster administrators must provide an encryption key during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.

Examine the output of this command:

The ACFS disk group is a normal redundancy disk group with 5 GB of free space.
To increase the size of the ACFS file system, you execute this command as the root user:
$ /sbin/acfsutil size +200M /u01/app/grid/acfsmount
Which two statements are true regarding the outcome of this command? (Choose two.)

• A.It resizes voli.
• B.It resizes the filesystem mounted on /u01/app/grid/acfsmount.
• C.It fails to resize the filesystem because it must be unmounted before resizing.
• D.It succeeds but leaves the file system unmounted.
• E.It fails to resize voli because it must be executed as a user belonging to the sysasm group.

Which two steps must always be performed to delete node host04 from an Oracle 19c Clusterware cluster that does not use Grid Naming Service (GNS)? (Choose two.)

• A.Run the crsctl unpin css - host04 command as root on host01, or on either host02 or host03.
• B.Run the crsctl delete node -n host04 command as root on host01, or on either host02 or host03.
• C.Run the rootcrs.pl -deconfig -force command as root on host04.
• D.Run the rootcrs.pl -deconfig -force command as root on host01, or on either host02 or host03.
• E.Run the crsct1 unpin css - host04 command as root on host04.
• F.Run the crsctl delete node -n host04 command as root on host04.

Which task must be performed before running the OPatch utility to patch Oracle Grid Infrastructure 19c?

• A.Update the path environment variable on the node where you will run the OPatch utility to point to the SORacle HOME/OPacch directory.
• B.Stage the patch on the cluster node where the OPacch utility will be executed.
• C.Update the path environment variable on each cluster node to point to the 50RACLE HOME/OPacch directory
• D.Stage the patch on all cluster nodes.

Which statement is true concerning the installation of an Oracle Grid Infrastructure 19c patchset and its status during the installation?

• A.When performing rolling patches, crsctl query crs softwareversion always displays the earliest version of the software running anywhere in the cluster.
• B.They can be applied in-place.
• C.Some Grid Infrastructure patchsets may not be intalled in a rolling fashion.
• D.When performing rolling patches, the vips for the node being patched are relocated to another node.
