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

Which two statements are true about initialization parameters for Clustered ASM instances? (Choose two.)

• A.The maximum value of ASM_POWER_LIMIT is 1024.
• B.ASM_POWER_LIMIT controls the number of RDBMS instances that can access a disk group while it is being rebalanced.
• C.The ASM_DISKGOUPS parameter is optional.
• D.The default value of INSTANCE_TYPE is ASM.
• E.A change to ASM_DISKSTRING requires a restart of all ASM instances for the change to take effect.

Which two statements are true about server categorization in Oracle 19c Clusterware? (Choose two.)

• A.All server attributes that may be used to determine the server category are discovered automatically by Oracle Clusterware.
• B.Different nodes in a cluster may belong to separate administrator-defined categories.
• C.A server may be added to only one category using the crsctl utility.
• D.Server categories can only be used for nodes running an application server.
• E.All nodes in a cluster belong to the same Oracle-supplied category.
• F.All server attributes used for categorization are administrator modifiable.

Which method should be used to convert a single-instance Oracle 19c Database to a RAC Database?

• A.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
• B.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
• C.Using dbca to create a template from the single-instance database and then to create a RAC database on the cluster using that template
• D.Using dbca to migrate the database to shared storage and then to start one or more RAC database instances on the cluster
