Q14. Which method can be used to convert a single-instance Oracle 12c Database to a RAC Database?
A. using DBCA to migrate the database to shared storage and then start one or more RAC databaseinstances on the cluster
B. using DBCA to create a template from the single-instance database and then to create a RAC database onthe cluster using that template
C. using the rconfig utility to create a template from the single-instance database and then using DBCA tocreate a RAC database on the cluster using that template

Answer: C
Q15. Which two statements are true regarding ASM Dynamic Volume manager (ADVM)?
A. To create an ADVM volume, disk group attributes COMAPTIBLE.ASM and COMPATIBLE.ADVM must beminimally set to 12.1.
B. An ADVM volume is individually named and can contain only one file system.
C. Only one ADVM volume can be created in an ASM disk group.
D. ADVM extends ASM by providing a device driver interface to storage backed by an ASM disk group.
E. File systems contained in ADVM volumes may only contain database files.
Answer: B,D
Explanation:
Each volume is individually named and may be configured for a single file system. Reference: https://docs.oracle.com/database/121/OSTMG/GUID-B7A61F3B-C22A-4021-A846F5EA749E79FF.htm#OSTMG32000 (See Note and the third para from the top.)
Q16. You administer a six-instance, policy-managed, multitenant RAC database CDB1 with three PDBs: PDB_1, PDB_2 and PDB_3.
Server pool prod_pool has a cardinality of three and all six hosts of the cluster app.
Examine these commands executed on HOST01:
$ srvctl add service –db CDB1 –pdb PDB_1 service AR –serverpool prod_pool –cardinality singleton $ srvctl start service –db CDB1 –service AR
Which two statements are true regarding the AR service?
A. AR runs as a singleton service in the server pool prod_pool and the AR service is available in each of theCDB1 instances.
B. AR is available on any one available CDB1 instance in prod_pool at any one time.
C. AR can fail over to any one of the available CDB1 instances.
D. AR is available only on the CDB1 instance on HOST01.
E. AR can fail over to any other available CDB1 instance in prod_pool.
Answer: C,D
Q17. Which two statements are true about ASM default templates?
A. Default data file templates are only created by ASM when a normal redundancy disk group is created.
B. Default template settings for redundancy depends on the disk group redundancy.
C. Default templates for a disk group can be modified.
D. Default template setting for striping depends on disk group redundancy.
E. Templates may be shared across disk groups.
Answer: A,B
Explanation:
Default template settings depend on the disk group type. The default template for data files for a normal redundancy.

C. All hub nodes in a flex cluster belong to the same Oracle-supplied category.
D. A server may be added to only one category using the crsctl utility.
E. All leaf nodes in a flex cluster belong to the same Oracle-supplied category.
F. All server attributes used for categorization are administrator modifiable.
Answer: C,E,F
Q19. You administer a three-instance, policy-managed, multitenant RAC database CDB1 with two PDBs: PDB_1 and PDB_2.
Examine these commands executed on host01:
$ srvctl add service –db CDB1 –pdb PDB_1 –serverpool prod_pool –cardinality singleton
$ srvctl start service –db CDB1 –service CRM $ srvctl stop service –db CDB1 –service CRM
Which three statements are true?
A. CRM is only available for new logins on the CDB1 instance on host01.
B. CRM is available for new logins on one CDB1 isntance.
C. The srvctl start service command automatically opens PDB_1 if not already opened.
D. The srvctl stop service command does not close PDB_1 on any instance of CDB1.
E. The CRM service is not available for new logins on any instance of CDB1.
Answer: B,D,E
Q20. The DGRP1 diskgroup has these attributes:
1.Normal redundancy
2.Two failgroups with four asmdisks in each failgroup
3.compatible.asm set to 12.1
The ASM_POWER_LIMIT is currently set to 1 in the ASM instances.
There are three databases whose instances are up and which access data in the DGRP1 diskgroup.
No other clients use this diskgroup.
You want to add two asmdisks to each failgroup, complete the rebalance as quickly as possible, by avoiding checks for access to allocation units, and then restore database availability.
Examine the list of actions:
1.Shut down all database instances using DGRP1.
2.Shut down all ASM instances.
3.Add the disks to DGRP1 specifying a large value for the REBALANCE POWER clause.
4.Start one ASM instances in restricted mode.
5.Wait for the rebalance to finish.
6.Mount DGRP1 in restricted mode.
7.Start all database instances whose files are stored in DGRP1.
8.Dismount DGRP1.
9.Mount DGRP1.
10.Start all ASM instances.
Identify the correct sequence of required steps:
A. 1, 2, 3, 4, 5, 2 ,10, 7
B. 1, 3, 5, 7
C. 1, 8, 6, 3, 5, 8, 9, 7
