Question 6 of 149

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

An ASM instance and database instances can coexist on the same hub node.

A database instance on a hub node can be a client of an ASM instance running on any leaf node.

A database instance on a hub node can be a client of an ASM instance running on any hub node.

A database instance on a leaf node can be a client of an ASM instance running on any hub node.

A database instance on a hub node uses an ASM instance as an I/O server when requesting I/O to diskgroups.

ASM Cluster File System (ASFS) can only be deployed on hub nodes.

Correct Answer: A, C, F

Question 7 of 149

Which two statements are true about Flex ASM in a Flex Cluster?

Oracle databases from releases older than 12c cannot use Flex ASM.

ACFS may only be configured on a hub node running an ASM instance.

Instances of ASM-based databases on hosts that have no ASM instance running, require Flex ASM.

Flex ASM requires that I/Os requests be sent through an ASM Proxy Instance, regardless of database and ASM instance placement in a cluster.

Hub nodes with connections from multiple leaf nodes must run an ASM instance.

Correct Answer: A, C

Oracle databases from releases older than 12c cannot use Flex ASM due to its reliance on features introduced in Oracle Database 12c. Additionally, instances of ASM-based databases on hosts that have no ASM instance running require Flex ASM to manage storage without a local ASM instance. These statements are accurate within the scope of Flex ASM in a Flex Cluster.

Question 8 of 149

A directory +DATA/ORCL/DATAFILE/USERS exists in ASM.
USERS is a user created directory; ORCL and DATAFILE are system generated directories.
Which two statements are true about user-created directories?

You can create subdirectories under the USERS directory.

You cannot rename a user-created subdirectory.

You cannot drop a directory containing aliases unless you delete the aliases first.

You cannot create a user-defined directory at the root (+) level.

You cannot create a nested subdirectory /USERS/2014 under USERS with a single CREATE DIRETORY command even if directory USER1 doesn’t exist.

Correct Answer: A, C

User-created directories in ASM allow for the creation of subdirectories, which makes option A correct. Additionally, you cannot drop a directory containing aliases without deleting the aliases first, making option C correct. Restrictions such as not being able to create a user-defined directory at the root (+) level or limitations on nesting subdirectories with single commands are not among the general rules, thus options D and E are incorrect.

Question 9 of 149

Which three components are integral parts of High Availability NFS (HANFS)?

Application VIP

DHCP

ExportFS

HAVIP

NFS

HAIP

Correct Answer: C, D, E

Question 10 of 149

You just added an ASM disk to the DATA diskgroup.
Which two can be used to monitor the rebalancing?

ams_cmd lsop

v$asm_disk

v$asm_operation

v$asm_diskgroup

v$session_longops

amscmd lsdg

Correct Answer: C, E

To monitor the rebalancing of an ASM disk added to the DATA diskgroup, the appropriate views to consult are v$asm_operation, which shows information about ongoing ASM operations, and v$session_longops, which provides details on long-running operations including rebalancing activities. v$asm_operation directly provides the current status and details of rebalancing, while v$session_longops gives a broader perspective on long-running tasks involving the database.
