A. The hub node is evicted from the cluster
B. Leaf nodes connected to the failing hub node are reconnected to a surviving hub node without
servicedisruption.
C. Cluster resources running on leaf nodes connected to the failed hub node are relocated to one or
moresurviving hub nodes.
D. Cluster resources running on leaf nodes connected to the failed hub node are relocated to one or
moresurviving leaf nodes.
E. Cluster resources running on the failed hub node are relocated to one or more surviving hub
nodes.
F. Cluster resources running on the failed hub node are relocated to one or more surviving leaf
nodes.
G. Cluster resources running on the failed hub node are relocated to one or more surviving hub
nodes or leafnodes, or both.

Answer: DFG

Question: 2

A. Oracle databases from releases older than 12c cannot use Flex ASM.
B. ASFS may only be configured on a hub node running an ASM instance.
C. Instances of ASM-based databases on hosts that have no ASM instance running, require Flex
ASM.
D. Flex ASM requires that I/Os requests be sent through an ASM Proxy Instance, regardless of
database andASM instance placement in a cluster.
E. Hub nodes with connections from multiple leaf nodes must run an ASM instance.

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.
