GFS and NFS only
OCFS2 only
OCFS2 and GFS only
GFS, OCFS2 and NFS
NFS only

Correct answer: E

What is the role of second item (server: myserver1) in the scenario where a template is being imported into a storage repository?

Exhibit:

It identifies the storage server where the template exists.
It identifies the server pool master so that the template will be in the proper server pool.
It identifies the virtual machine server that will be used to clone the imported template.
It identifies thedefault virtual machine server for VM creation from the template.
It identifies a server with sufficient local disk to store the template content temporarily.
It identifies the Oracle VM server assign to target repository that extract the template content and transfer it to the designated storage repository.

Correct answer: F

In Oracle VM 2.2.x, what directory will the root repository be symbolically linked to on each Oracle VM Server attached to a storage pool?

/OVS3
/var/ovs/mount/root
/var/ovs/mount/OVSROOT
/OVSROOT
/var/OVS
/opt/ovs

Correct answer: E

Explanation:

The /OVS directory is the cluster root and is a symbolic link mounted to the/var/ovs/mount/uuid directory.For example, the mount command might display something similar to:# mountexample.com:/OVS on /var/ovs/mount/F4135C096045458195057412169071E5 type nfs (rw,addr=192.168.2.20)And the ls command might display something similar to:# ls -l /OVSlrwxrwxrwx 1root root 47 Sep 18 16:15 /OVS -> /var/ovs/mount/F4135C096045458195057412169071E5

The /OVS directory is the cluster root and is a symbolic link mounted to the/var/ovs/mount/uuid directory.For example, the mount command might display something similar to:

# mount

example.com:/OVS on /var/ovs/mount/F4135C096045458195057412169071E5 type nfs (rw,addr=192.168.2.20)

And the ls command might display something similar to:

# ls -l /OVS

lrwxrwxrwx 1root root 47 Sep 18 16:15 /OVS -> /var/ovs/mount/F4135C096045458195057412169071E5

Which statement is true regarding using a YUM repository from Oracle VM Manager?

Once a YUM is repository configured, Oracle VM manager automatically distribute the configuration file to all Oracle VM servers.
After configuring the YUM repository you must manually copy the configuration to all Oracle VM servers that will use it.
Prior to setting the YUM repository, you must ensure that all Oracle VM servers has the latest patch set.
A YUM repository once configured cannot be changed.

Correct answer: A

A number of high priority virtual machines require significant file system access and you are trying to decide what type of memory impact on dom0 they will have. Which two are best practices you should consider for memory use in dom0?

You should always run a find command on dom0 to fill the file system buffer cache for bestperformance.
You should not run a find command on dom0 as it will use up Dom0 memory and potentiallycause double buffering with virtual machines.
When increasing load with additional virtual machines, you should always add more memory todom0.
When increasing load with additional virtual machines, you generally wont add more memory todom0.

Correct answer: A, C

When crating a repository on an iSCSI LUN, how should the LUN be formatted?

The LUN should be formatted with ext3 from every participating node in the cluster.
The LUN should be formatted with ext3 from a single node in the cluster.
The LUN should be formatted with OCFS2 fromevery participating node in the cluster.
The LUN should be partitioned, and then formatted with OCFS2 from every participating node in the cluster.
The LUN should be formatted with OCFS2 from a single node in the cluster.

Correct answer: E

In hardware virtualized environment, which answer best describes the drivers that are used in dom0 and the guest to communicate block I/O requests?

QEMU emulation is used in dom0, and a blkfront driver is used in the guest.
A native device driver is used in dom0, and QEMU emulation is used in the guest.
A blkfront driver is used in dom0, and a blkback driver is usedin the guest
QEMU emulation is used in dom0, and a native device driver is used in the guest.
Native drivers are used in both dom0, and the guest.

Correct answer: A

What two configuration files are associated with an OCFS2 cluster?

/etc/ocfs2/cluster.conf
/etc/sysconfig/ocfs2
/etc/sysconfig/cluster.conf
/etc/sysconfig/o2cb
