  2. B
    A database instance on a hub node can be a client of an ASM instance running on any leaf node.
  3. C
    A database instance on a hub node can be a client of an ASM instance running on any hub node.
  4. D
    A database instance on a leaf node can be a client of an ASM instance running on any hub node.
  5. E
    A database instance on a hub node uses an ASM instance as an I/O server when requesting I/O to diskgroups.
  6. F
    ASM Cluster File System (ASFS) can only be deployed on hub nodes.

Correct Answer:
ACF

Question #7

  2. B
    ACFS may only be configured on a hub node running an ASM instance.
  3. C
    Instances of ASM-based databases on hosts that have no ASM instance running, require Flex ASM.
  4. 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.
  5. E
    Hub nodes with connections from multiple leaf nodes must run an ASM instance.

Correct Answer:
AC

Question #8
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?

Question #9
Which three components are integral parts of High Availability NFS (HANFS)?
  1. A
    Application VIP
  2. B
    DHCP
  3. C
    ExportFS
  4. D
    HAVIP
  5. E
    NFS
  6. F
    HAIP

Correct Answer:
CDE
CD: In addition to ACFS/ADVM and ASM, HANFS also relies on new Oracle 12.1 Clusterware (CRS) resources, namely the HAVIP and the ExportFS.
DE: High Availability Network File Storage (NFS) for Oracle Grid Infrastructure provides uninterrupted service of NFS V2/V3/V4 exported paths by exposing NFS exports on Highly Available Virtual IPs (HAVIP) and using Oracle Clusterware agents to ensure that the HAVIPs and NFS exports are always online.
