NO.1 Which four statements are true about ADVM interoperability?
A. Using fdisk or similar disk utilities to partition ADVM-managed volumes is not supported
B. On Linux platforms, the raw utility can be used to map ADVM volume block devices to raw volume
devices.
C. The creation of multipath devices over ADVM devices is not supported.
D. You may create ASMLIB devices over ADVM devices to simplify volume management.
E. ADVM does not support ASM storage contained in Exadata.
F. F. ADVM volumes cannot be used as a boot device or arootfile system.
Answer: A,C,E,F
NO.2 Which two types of files can be stored In an ASM clustered file system?
A. OCR and Voting Disk files
B. data files for external tables
C. Oracle database executable
D. Grid Infrastructure executables
E. data files for tablespaces F. archive log files
Answer: B,C
NO.3 Your production environment cluster is running Oracle Enterprise Linux and currently has four nodes.
You are asked to plan for extending the cluster to six nodes. Which three methods are available to add the
new nodes?
A. silent cloning usingcrsctlclone cluster and ssh
B. a GUI interface from Enterprise Manager
C. with the Oracle Universal Installer using runInstaller clone <nodename>
D. silent cloning usingperl clone.pl silent either with parameters in a file or in line
E. using addNode.sh
Answer: B,D,E
NO.4 Which three actions would be helpful in determining the cause of a node reboot?
A. determining the time of the node reboot by using the uptime command and subtracting the up time
from the current system time
B. looking for messages such as "Oracle CSSD failure. Rebooting for cluster integrity" in
/var/log/messages
C. using the crsctl command to view tracing information
D. inspecting the ocssd log for "Begin Dump" or "End Dump" messages
E. inspecting the database alert log for reboot messages
Answer: A,B,D
NO.5 You want to create an ACFS on an ADVM volume using a shell script and the appropriate command-line
utilities. These are the requirements:
- The dynamic volume file must use space in the VOLFILE disk group with a size of 500 M and be called
prodvol.
- The mount point called /acfs already exists.
Which four steps must be performed to achieve this?
A. As the Grid Infrastructure owner, run mount -t acfs /dev/asm/prodvol-417 /acfs to mount the file system.
B. As the Grid Infrastructure owner, run asmcmd volinfo -d volfile prodvol to determine the volume
information.
C. As the Grid Infrastructure owner, run asmcmd volcreate -d volfile -s 500M prodvol to create the volume
file.
D. As the Grid Infrastructure owner, run mkfs -t acfs /dev/asm/prodvol-417 to create the file system.
E. As root, run mount -t acfs /dev/asm/prodvol-417 /acfs to mount the file system.
F. As root, run mkfs -t acfs /dev/asm/prodvol-417 to create the file system.
Answer: B,C,D,E
NO.6 You enter the following command: crsctl status resource MyApp
You get this output: NAME=MyApp
TYPE=cluster_resource TARGET=ONLINE STATE=ONLINE on RACNODE4
MyApp is a policy-managed resource using a server pool with two nodes called RACNODE3 and
RACNODE4 and has a cardinality of 1.
What are the meanings of the target and state status values?
A. MyApp is currently active on RACNODE4 and is meant to be active only on RACNODE4.
B. MyApp is meant to be active, is currently active on RACNODE4, but the Grid Infrastructure may start
MyApp on RACNODE3 due to failovers.
C. MyApp is active on RACNODE4 and was manually started.
D. MyApp should also be online on RACNODE3 because it is a cluster_resources type that must be
active on at least two nodes in the cluster, thereby overriding the CARDINALITY attribute.
Answer: B
NO.7 Your cluster Is subject to a service-level agreement that allows for little scheduled down time You want
to use patching and maintenance methods that permit the Oracle Grid Infrastructure and Oracle RAT
Databases to be available as much as possible.
Which two techniques will work some or all of the time to provide you with minimum down time?
A. rolling upgradeable and in place patch sets
B. idling upgradeable and out of place patch bundles
C. rolling upgradeable and out of place patch sets
D. rolling upgradeable and in place patch bundles
E. rolling upgradeable and out of place one-off patches
Answer: C,D
NO.8 After Oracle Grid Infrastructure has been installed, you should take a few moments to verify the
installation.
Which two actions would be useful in verifying the installation.?
A. Run the crsctl status resource t command to confirm that all necessary cluster resources are online.
B. Use the operating system utilities to verify that your SCAN addresses are being properly resolved.
C. Start Oracle Enterprise Manager and check all monitored targets.
D. Run the cluvfy comp nodecon n all verbose command to verify the entire Grid Infrastructure
installation.
Answer: A,B
