QUESTION 126
Which three statements are true about persistent lightweight jobs?

A.    A user cannot set privileges on them.
B.    They generate large amounts of metadata.
C.    They may be created as fully self-contained jobs.
D.    They must reference an existing Scheduler Program.
E.    The are useful when users need to create a large number of jobs quickly.

Answer: ADE
Explanation:
http://docs.oracle.com/database/121/ADMIN/schedover.htm#ADMIN12668
Unlike regular jobs, they are not schema objects.
Because lightweight jobs are not schema objects, you cannot grant privileges on them. A lightweight job inherits privileges from its specified program. Thus, any user who has a certain set of privileges on the program has corresponding privileges on the lightweight job.
Use lightweight jobs when you have many short-duration jobs that run frequently. Under certain circumstances, using lightweight jobs can deliver a small performance gain.
A lightweight job must reference a program object (program) to specify a job action. The program must be already enabled when the lightweight job is created, and the program type must be either ‘PLSQL_BLOCK’ or ‘STORED_PROCEDURE’.

QUESTION 127
You restore and recover your database to a new host by using an existing RMAN open database backup. Which step must you perform next?

C.    Set a new database identifier (DBID) for the newly restored database.
D.    Use the RMAN set newname and switch commands to switch to new files.

Answer: B

QUESTION 130
You plan to use the In-Database Archiving feature of Oracle Database 12c, and store rows that are inactive for over three months, in Hybrid Columnar Compressed (HCC) format. Which three storage options support the use of HCC?

A.    ASM disk groups with ASM disks consisting of Exadata Grid Disks
B.    ASM disk groups with ASM disks consisting of LUNS on any Storage Area Network array
C.    ASM disk groups with ASM disks consisting of any zero padded NFS-mounted files
D.    Database files stored in ZFS and accessed using conventional NFS mounts
E.    Database files stored in ZFS and accessed using the Oracle Direct NFS feature
F.    Database files stored in any file system and accessed using the Oracle Direct NFS feature
G.    ASM disk groups with ASM disks consisting of LUNs on Pillar Axiom Storage arrays

Answer: AEG
Explanation:
HCC requires the use of Oracle Storage ?Exadata (A), Pillar Axiom (G) or Sun ZFS Storage Appliance (ZFSSA).
Note:
* Hybrid Columnar Compression, initially only available on Exadata, has been extended to support Pillar Axiom and Sun ZFS Storage Appliance (ZFSSA) storage when used with Oracle Database Enterprise Edition 11.2.0.3 and above.
* Oracle offers the ability to manage NFS using a feature called Oracle Direct NFS (dNFS). Oracle Direct NFS implements NFS V3 protocol within the Oracle database kernel itself. Oracle Direct NFS client overcomes many of the challenges associated with using NFS with the Oracle Database with simple configuration, better performance than traditional NFS clients, and offers consistent configuration across platforms.

QUESTION 131
You notice a performance change in your production Oracle 12c database. You want to know which change caused this performance difference. Which method or feature should you use?

A.    Compare Period ADDM report
B.    AWR Compare Period report
C.    Active Session History (ASH) report
D.    taking a new snapshot and comparing it with a preserved snapshot

Answer: A
Explanation:
Comparing Current System Performance to a Baseline Period
You may have noticed a performance change on a production system and would like to know why, or you may have implemented a change to a production system and want to know the effect of the change, such as increased concurrency waits. The Compare Period ADDM compares the performance of the database server in two time periods, and returns a report describing the performance changes and the root origin of the changes. The Advisor can analyze any Oracle RDBMS version 10.2.0.4 or later monitored by Cloud Control. The following procedure explains how to initiate a report from the Compare Period ADDM.

QUESTION 132

SEED
SYSTEMDATAFILESSIZE125M AUTOEXTEND ON NEXT10M MAXSIZEUNLIMITED
SYSAUXDATAFILESSIZE100M;
Which three statements are true?

A.    It creates a multitenant container database with a root and a seed pluggable database (PDB) that are opened in read-write and read-only modes, respectively.
B.    The files created for both the root and seed databases use Oracle Managed Files (OMF).
C.    It creates a multitenant container database with the root and seed databases opened and one PDB mounted.
D.    It sets the users tablespace as the default for both the root and seed databases.
E.    undotbs1is used as the undo tablespace for both the root and seed databases.
F.    It creates a multitenant container database with the root database opened and the seed database mounted.

Answer: ABE
Explanation:
The seed actually doesn’t use anything since it’s read-only, but any PDB created from the seed will use the undotbs1 undo tablespace. Each PDB can have its own default tablespace, but cannot change the undo tablespace.
