Question 1
Which three statements are true about ASM Cloud File System (ACFS) replication?
- ACFS auditing information is replicated from the primary file system to the standby file system.
- One site of an ACFS replication configuration can be host both primary and standby file systems.
- Replication is automatically terminated if the primary file system has less than 2GB free space.
- Standby redo log files are required on the standby site for synchronous redo transport.
- The privilege SYSREPL has been introduced for ACFS replication.
Correct answer: BCD
Explanation:
B: A site can host both primary and standby file systems. C: If the primary file system has less than 2 GB available free disk space, Oracle ACFS attempts to automatically terminate replication on the primary file system.D: On the standby system, the remote file server (RFS) receives redo data over the network from the LGWR process and writes the redo data to the standby redo log files.Reference: https://docs.oracle.com/database/121/OSTMG/GUID-8522E0B6-BE6E-4BE3-B7C7-5EA2ED4A602C.htm#OSTMG34600https://docs.oracle.com/cd/B19306_01/server.102/b14239/log_transport.htm#i1280979 B: A site can host both primary and standby file systems.

Question 2
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?
- COMAPTIBLE.ASM and COMPATIBLE.ADVM must be set to 11.2 or higher for the DATA disk group.
- The DATA disk group must not be created with external redundancy.
- The DATA disk group must not contain any other volume.
- The DATA disk group must have at least three failure groups.
- The DATA disk group must have an AU size of 1MB.
Correct answer: AD
Explanation:
The compatibility parameters COMPATIBLE.ASM and COMPATIBLE.ADVM must be set to 11.2 or higher for the disk group. A high redundancy disk group must contain at least three failure groups. Reference: https://docs.oracle.com/cd/E11882_01/server.112/e18951/asmdiskgrps.htm#OSTMG10072https://docs.oracle.com/cd/E18283_01/server.112/e16102/asmdiskgrps.htm The compatibility parameters COMPATIBLE.ASM and COMPATIBLE.ADVM must be set to 11.2 or higher for the disk group. A high redundancy disk group must contain at least three failure groups.

Question 3
Which two statements are true about vsam views in a clustered environment?
- They exist both in ASM and RDBMS instances, and display the same output.
- Their names can be seen in dict when connected to an ASM instance.
- Their names can be seen in vfixed_table when connected to an instance of any type that is started.
- They exist in both in ASM and RDBSM instances, but they can display different outputs depending on the instance type.
- gvasm_attribute can be used to display the ASM_POWER_LIMIT attribute of all ASM instances in the cluster.
Correct answer: BD
Explanation:
You can use the views to obtain information about Oracle Automatic Storage Management Cluster File System (Oracle ACFS). These views are accessible from the Oracle ASM instance. References: https://docs.oracle.com/cd/E11882_01/server.112/e18951/asmviews.htm#OSTMG94187 You can use the views to obtain information about Oracle Automatic Storage Management Cluster File System (Oracle ACFS). These views are accessible from the Oracle ASM instance.
