Q1. Examine the output of this command: ASMCMD> volinfo –G ACFS -a Diskgroup Name: ACFS Volume Name: VOL1 Volume Device: /dev/asm/vol1-280 State: ENABLED Size (MB): 248 Resize Unit (MB): 32 Redundancy: MIRROR Stripe Columns: 4 Stripe Width (K): 128 Usage: ACFS Mountpath: /u01/app/grid/acfsmount The ACFS disk group is a normal redundancy disk group with 5 GB of free space. To increase the size of the ACFS file system, you execute this command as the root user: $ /sbin/acfsutil size +200M /u01/app/grid/acfsmount
Which two statements are true regarding the outcome of this command?
A. It resizes VOL1.
B. It fails to resize the filesystem because it must be unmounted before resizing.
C. It fails to resize VOL1 because it must be executed as a user belonging to the SYSASM group.
D. It succeeds but leaves the filesystem unmounted.
E. It resizes the filesystem mounted on /u01/app/grid/acfsmount.
Answer: A,D

Q3. Examine the output of the asmcmd and srvctl commands:
$ asmcmd showclustermode
ASM cluster : Flex mode enabled $ srvctl status asm –detail ASM is running on host01,
host03 ASM is enabled.
$ srvctl config asm
ASM home: /u01/app/12.1.0/grid
Password file: +DATA/orapwASM
ASM listener: LISTENER
ASM instance count: 2
Cluster ASM listener: ASMNET1LSNR_ASM Then you execute this command:
$ srvctl relocate asm – currentnode host03 –targetnode host02
Which three statements are true regarding the execution of this command based on the
output shown?
A. It fails because an ASM instance is not configured to run on HOST02.
B. It succeeds and starts an ASM instance on HOST02 and shuts down the ASM instance on HOST03.
C. It succeeds and 12c database instances connected to the ASM instance on HOST03 can be reconnectedto the ASM instance on HOST02.
D. It fails because the ASM instance has not been shut down first on HOST03.
E. It succeeds and starts an ASM instance on HOST02 but the ASM instance on HOST03 is not shut downuntil all connected clients disconnected.
F. It succeeds and 12c database instances connected to the ASM instance on HOST03 can be reconnectedto the ASM instance on HOST01.
Answer: C,E,F

Which statement is true about the srvctl start service command?
A. It opens the PRDPDB1 PDB if not already opened.
B. It can open the PRDPDB1 PDB only if it is policy managed.
C. It can open the PRDPDB1 PDB automatically.
D. It can open the PRDPDB1 PDB only if it is manually managed.
Answer: B
Q6. Which three statements are true about the administration and use of policy sets in Oracle 12c Clusterware?
A. All server pools in a cluster are controlled by the policy set, when user-defined policy management is used.
B. Servers in a server pool outside the control of policy set are never affected by policy changes, when user-defined policy management is used.
C. Clusterware administrators cannot directly modify the policy set when Quality of Service (QoS)Management is used.
D. A server pool can have the same attributes defined for different policies in the policy set, when user-definedpolicy management is used.
E. A server pool can have different attributes defined for different policies in the policy set, when user-definedpolicy management is used.
Answer: A,C,E
Q7. Which two statements are true about database service administration in a RAC environment?
A. When services are created with srvctl, tnsnames.ora is automatically updated.
B. When services are created with srvctl, the service is not started automatically.
C. Service attributes can be modified, unless an instance hosting the service is in restricted mode.
D. When the DBMS_SERVICE package is used to modify a service, the CRS resource is automaticallysynchronized with the changes.
E. When the DBMS_SERVICE package is used to delete a service, it is automatically removed from the OCR.
F. When services are started with srvctl, they are automatically added to the data dictionary of the hostingdatabase if not already defined.
Answer: A,E
