Question 5:
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 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.
Correct Answer: ACF
Section: (none)
Architecturally Oracle Flex Cluster comprises of a Hub and Leaf architecture 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.

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.
Correct Answer: AC
Section: (none)
Question 7:

B. You cannot rename a user-created subdirectory.
C. You cannot drop a directory containing aliases unless you delete the aliases first.
D. You cannot create a user-defined directory at the root (+) level.
E. 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: AC
Section: (none)
Question 8:
Which three components are integral parts of High Availability NFS (HANFS)?
A. Application VIP
B. DHCP
C. ExportFS
D. HAVIP
E. NFS
F. HAIP
Correct Answer: CDE
Section: (none)
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.

Question 9:
You just added an ASM disk to the DATA diskgroup.
Which two can be used to monitor the rebalancing?
A. ams_cmd lsop
B. v$asm_disk
C. v$asm_operation
D. v$asm_diskgroup
E. v$session_longops
F. amscmd lsdg
Correct Answer: CD
Section: (none)
C: Oracle ASM automatically rebalances when the configuration of a disk group changes. By default, the ALTER DISKGROUP statement does not wait until the operation is complete before returning. Query the V$ASM_OPERATION view to
monitor the status of this operation.
D: Verify that the rebalance is waiting:
SQL> select * from v$asm_operation
where group_number = (select GROUP_NUMBER from v$asm_diskgroup where NAME=\’BDT\’);

D: Only an audit manager can run the acfsutil audit purge command.
E: acfsutil audit read marks the audit trail to indicate to the audit manager that the log archive file for the current node has been reviewed, backed up as necessary, and is safe to purge.
Incorrect Answers:
B: acfsutil audit archive does not address file size.

Question 12:
Which three statements are true regarding ACFS snapshots in Oracle 12c ASM?
A. They are contained in a directory on the same volume as their parent file system.
B. All ACFS snapshot operations for all filesystem are serialized clusterwide.
C. You can create a snapshot from an existing snapshot.
D. They can be administered using ASMCMD.
E. They can only be accessed when the file system is mounted.
F. They are always point-in-time copies of the parent file system.

Question 13:
Which two statements are true about initialization parameters for Clustered ASM instances?
A. A change to ASM_DISKSTRING requires a restart of all ASM instances for the change to take effect.
B. ASM_POWER_LIMIT controls the number of RDBMS instances that can access a disk group while it is being rebalanced.
C. The ASM_DISKGROUP parameter is optional.
D. The default value of INSTANT_TYPE is ASM.
E. The maximum value of ASM_POWER_LIMIT is 1024.
Correct Answer: CE
Section: (none)
C: The default value of the ASM_DISKGROUPS parameter is a NULL string. If the parameter value is NULL or is not specified, then ASM does not mount any disk groups.
E: The ASM_POWER_LIMIT initialization parameter specifies the default power for disk rebalancing in a disk group. The range of values is 0 to 1024.
Incorrect Answers:
B: The ASM_POWER_LIMIT initialization parameter specifies the default power for disk rebalancing in a disk group. The range of values is 0 to 1024.
D: The default value of INSTANT_TYPE is RDBMS.

`compatible.rdbms\’ = \’11.12\’,
`compatible.advm\’ = \’11.12\’,
`content_type\’ = `recovery\’;
Which two statements a true about this disk group, created using Grid Infrastructure 12.1?
A. Each disk in each of the three fail groups is a mirror of the corresponding disk of the other two failure groups.
B. File created in this disk group always has two copies for each allocation unit: one primary and one secondary.
C. It can contain ASM Dynamic Volume Manager (ADVM) volumes.
D. Any database instance with the COMPATIBLE parameter set to 11.2 or higher can access it.
E. The ASM compatible attributes can be changed to 11.1 for this disk group.
Correct Answer: BC
Section: (none)
B: NORMAL REDUNDANCY requires the existence of at least two failure groups (see the FAILGROUP clause that follows). Automatic Storage Management provides redundancy for all files in the disk group according to the attributes specified in the disk group templates. NORMAL REDUNDANCY disk groups can tolerate the loss of one group.
C: The COMPATIBLE.ADVM attribute determines whether the disk group can contain Oracle ADVM volumes.
Incorrect Answers:
E: The COMPATIBLE.ADVM attribute value must be set to 11.2 or higher.
