Question 1

You are administering a database stored in Automatic Storage Management (ASM). You use RMAN to back up the database and the MD_BACKUP command to back up the ASM metadata regularly. You lost an ASM disk group DG1 due to hardware failure.
In which three ways can you re-create the lost disk group and restore the data? (Choose three.)

Use the MD_RESTORE command to restore metadata for an existing disk group by passing the existing disk group name as an input parameter and use RMAN to restore the data.

Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group and data on the disk group.

Use the MD_RESTORE command to restore the disk group with the changed disk group specification, failure group specification, name, and other attributes and use RMAN to restore the data.

Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group name and same set of disks and failure group configuration, and use RMAN to restore the data.

Use the MD_RESTORE command to restore both the metadata and data for the failed disk group.

Use the MKDG command to add a new disk group DG1 with the same or different specifications for failure group and other attributes and use RMAN to restore the data.

Question 6

Oracle Grid Infrastructure for a stand-alone server is installed on your production host before installing the Oracle Database server. The database and listener are configured by using Oracle Restart.
Examine the following command and its output:
$ crsctl config has CRS-4622: Oracle High Availability Services auto start is enabled. What does this imply?

When you start an instance on a high with SQL *Plus dependent listeners and ASM disk groups are automatically started.

Question 11

Which two statements are true when row archival management is enabled? (Choose two.)

The ORA_ARCHIVE_STATE column visibility is controlled by the ROW ARCHIVAL VISIBILITY session parameter.

The ROW ARCHIVAL VISIBILITY session parameter defaults to active rows only.

The ORA_ARCHIVE_STATE column is visible if referenced in the select list of a query.

The ORA_ARCHIVE_STATE column is updated automatically by the Oracle Server based on activity tracking columns, to Indicate that a row is no longer considered active.
