Question: 1

Which three statements are true concerning policy-based cluster management in Oracle 12c Clusterware?

A. Server Pools must be managed with the crsctl utility for servers hosting an application or other administrator-defined high-availabilityresource.
B. All servers in a new cluster installation belong to the generic server pool.
C. The server pool contains servers that host administrator-defined high availability resources.
D. Server pools must be managed with the srvctl utility for servershosting a database.
E. All servers in a new cluster installation belong to the free server pool.

Answer: C,D,E

Explanation:
C: Server pools divide the cluster into logical groups of servers hosting both singleton and uniform applications. The application can be a database service or a non-database application.
D: You manage server pools that contain Oracle RAC databases with the Server Control (SRVCTL) utility.
E: When Oracle Clusterware is installed, two internal server pools are created automatically:Generic and Free. All servers in a new installation are assigned to the Free server pool, initially

Question: 2

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 instance.
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: C,D,E

Examine this command to create a volume in the DATA disk group:
SQL>ALTER DISKGROUP DATA ADD VOLUME vo11 SIZE 10g HIGH
STRIPE_WIDTH 1M;
STRIPE_COLUMNS 1;
The DATA disk group has 50GB free space.
Which two are prerequisites for successful execution of this command?

A. COMAPTIBLE.ASM and COMPATIBLE.ADVM must be set to 11.2 or higher for the DATA disk group.
B. The DATA disk group must not be created with external redundancy.
C. The DATA disk group must not contain any other volume.
D. The DATA disk group must have at least three failure groups.
E. The DATA disk group must have an AU size of 1MB.

Answer: A,D

Explanation:
The compatibility parameters COMPATIBLE.ASM and COMPATIBLE.ADVM must be set to 11.2 or higher for the disk group. A high redundancy disk group must contain at least three failure groups.

Question: 4

Which two statements are true about v$asm – views in clustered environment?

A. They exist both in ASM and RDBMS instances, and display the same output.
B. Their names can be seen in dict when connected to an ASM instance.
C. Their names can be seen in v$fixed_table when connected to an instance of any type that is started.
D. They exist in both in ASM and RDBSM instances, but they can display different outputs depending on the instance type.
E. gv$asm_attribute can be used to display the ASM_POWER_LIMIT attribute of all ASM instances in the cluster.

Answer: B,D

Explanation:
You can use the views to obtain information about Oracle Automatic Storage Management Cluster File System (OracleACFS). These views are accessible from the Oracle ASM instance.

Question: 5

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 diskgroup type. The default template for data files for a normal redundancy.

Question: 6

Which three statements are true regarding Flex ASM on a four-node cluster consisting of three-hub nodes and a leaf node?

A. An ASM instance and database instances can coexist on the same hub node.
B. A database instance on a hub node canbe a client of an ASM instance running on any leaf node.
C. A database instance on a hub node can be a client of an ASM instance running on any hub node.
D. A database instance on a leaf node can be a client of an ASM instance running on any hub node.
E. A database instance on a hub node uses an ASM instance as an I/O server when requesting I/O to diskgroups.
F. ASM Cluster File System (ASFS) can only be deployed on hub nodes.

Answer: A,C,F

Explanation:
Architecturally Oracle Flex Cluster comprises of a Hub and Leafarchitecture where in only the Hub nodes will only have direct access to Oracle Cluster Registry (OCR) and Voting Disk (VD). However application can access the database via Leaf nodes without ASM instance NOT running on Leaf nodes. The connection to the database is through Hub making it transparent for the application.
Note:
Hub Nodes are connected among them via private network and have direct access to the shared storage just like previous versions. These nodes are the ones that access the Oracle Cluster Registry (OCR) and Voting Disk (VD) directly.
Leaf Nodes are lighter and are not connected among them, neither accesses the shared storage like the Hub Nodes. Each Leaf Node communicates with the Hub Node that is attached to, and it is connected to the cluster via the Hub Node that is linked to.
