Q26. Which two descriptions best describe Oracle's support policy for Oracle products hosted on other vendors' x86 server virtualization products?
A. Oracle must have a vendor response agreement with the virtualization vendor before Oracle will respond to support calls for products running on their virtualization products.
B. Oracle will provide support for issues that are known to occur on the native OS.
C. Oracle may request that the problem be reproduced on the native hardware.
D. Both Oracle and the virtualization vendor must have a joint support process plan in place before Oracle will respond to support calls for products running on the vendor's virtualization products.
E. Oracle does not support any of its products on any non-Oracle virtualization platform.
Q27. When crating a repository on an iSCSI LUN, how should the LUN be formatted?
A. The LUN should be formatted with ext3 from every participating node in the cluster.
B. The LUN should be formatted with ext3 from a single node in the cluster.
C. The LUN should be formatted with OCFS2 from every participating node in the cluster.
D. The LUN should be partitioned, and then formatted with OCFS2 from every participating node in the cluster.
E. The LUN should be formatted with OCFS2 from a single node in the cluster.
Q28. Which disk protocol is the default disk type for disks in a paravirtualized guest?
A. HD (IDE)
B. SD (SCSI)
Q29. Which two are true of an NFS repository when used with Oracle VM?
A. NFS repositories are excellent for storing guests' root file systems.
B. NFS is a more expensive option than iSCSI or SAN fabrics.
C. OCFS2 must be used as the filesystem format for volumes exposed through NFS.
D. NFS shares mounted directly in a guest require the DM-NFS driver to be installed on the guest.
E. NFS is supported for use in RAC only when mounted from the guest (not domO).
First of all here you have to select two options but answer shows one. A is ok.
A performance comparison of NFS and iSCSI for IP-Networked Storage showed that iSCSI
is faster than NFS because iSCSI caches and updates meta-data asynchronously and
transfers blocks rather than files. So the options B is right.
Q30. What two steps would best harden an Oracle VM Server installation?
A. Avoid installing additional software in dom0.
B. Enable firewalling in dom0.
C. Install virus checking software in dom0.
D. Use Trusted Computing Modules for Xen0.
E. Do not share physical network cards between hosts that are on a different subnet.
