  • 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.



Question 2
Which three statements are true about ASM Cloud File System (ACFS) replication?

  • A: ACFS auditing information is replicated from the primary file system to the standby file system.
  • B: One site of an ACFS replication configuration can be host both primary and standby file systems.
  • C: Replication is automatically terminated if the primaries file system has less than 2GB free space.
  • D: Standby redo log files are required on the standby site for synchronous redo transport.
  • E: The privilege SYSREPL has been introduced for ACFS replication.



Question 3
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.



Question 4
Which two statements are true about vsam views in a 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 vfixed_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: gvasm_attribute can be used to display the ASM_POWER_LIMIT attribute of all ASM instances in the cluster.



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.

  • A: An ASM instance and database instances can coexist on the same hub node.
  • B: A database instance on a hub node can be 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.



Question 7
Which two statements are true about Flex ASM in a Flex Cluster?

  • A: Oracle databases from releases older than 12c cannot use Flex ASM.
  • B: ACFS 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 and ASM instance placement in a cluster.
  • E: Hub nodes with connections from multiple leaf nodes must run an ASM instance.



Question 8
