Explanation:
All Oracle ACFS snapshot operations are serialized clusterwide in the kernel.
You chose to create a snapshot image on an existing snapshot group, select a snapshot group from
the existing snapshot group table (make sure you select a snapshot group that has not reached its
maximum limit of snapshot images).
Before you can access the files on a file system, you need to mount the file system.

Explanation:
Oracle Clusterware manages applications when they are registered as resources with
OracleClusterware. Oracle
Clusterware has access to application-specific primitives that have the ability to start, stop, and
monitor a specific resource. Oracle Clusterware runs all resource-specific commands through an
entity called an agent.
Note: When initializing the agent framework, if any of the mandatory entry points are not provided,
then the agent framework invokes a script pointed to by the ACTION_SCRIPT resource attribute.

NO.4 Which three statements are true regarding Flex ASM on a four-node cluster consisting of three-
hub nodes and a leaf node?
A. A database instance on a hub node canbe a client of an ASM instance running on any leaf node.
B. A database instance on a leaf node can be a client of an ASM instance running on any hub node.
C. A database instance on a hub node uses an ASM instance as an I/O server when requesting I/O to
diskgroups.
D. ASM Cluster File System (ASFS) can only be deployed on hub nodes.
E. An ASM instance and database instances can coexist on the same hub node.
F. A database instance on a hub node can be a client of an ASM instance running on any hub node.
Answer: D,E,F

1z1-068 日記   
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.
