Question 7

Which method can be used to convert a single-instance Oracle 12c Database to a RAC Database?

Select an option, then click Submit answer.

  • ○

    using DBCA to migrate the database to shared storage and then start one or more RAC database instances on the cluster
  • ○

    using DBCA to create a template from the single-instance database and then to create a RAC database on the cluster using that template
  • ○

    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
  • ○

    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.
Question 8

Examine this command and output:

[root@host01 ~]# / sbin/acfsutil snap create snap001 /u0l/app/grid/acfsmount/

acfsutil snap create: Snapshot operation is complete.

Examine this command:

[root@host01 ~]# / sbin/acfsutil snap create –p snap001

Snap002 /u01/app/grid/ acfsmount/

Which statement must be true for the successful execution of the second command?

Select an option, then click Submit answer.

  • ○

  • ○

    The underlying ADVM volume must be configured with high redundancy.
  • ○

    The parent snapshot must be read/write.
Question 9

Examine the output of the asmcmd and srvct1 commands:

You execute this command:

$ srvctl modify asm –count 2

All databases on the cluster are running from Oracle 12c homes.

Which statement is true about the outcome of this command?

Select an option, then click Submit answer.

  • ○

    One ASM instance is shut down and the instance count is reduced by one.
  • ○

    ASM instances continue running on all three nodes until all database instances connected to one of the ASM instances shut down.
  • ○

    The command fails because one ASM instance must be shut down manually before executing the command.
  • ○

    The command fails because the instance count cannot be reduced to less than the minimum value of 3.
