Answer: B,D 


Q43. A 64-bit Windows XP Installation CD has been ripped to an ISO file named WinXP.iso, and has been put in the /OVS/iso_pool/ directory with user and group-readable permissions. When navigating to the Import ISO screen in the Oracle VM Manager, no ISOs are available for import. 

What has gone wrong? 

A. 64-bit Windows XP is not a supported guest operating system, and the Oracle VM Manager will not show unsupported guest ISO files. 

B. The user has not selected the appropriate ISO Group on the Import form. 

C. The ISO file should be located under a subdirectory of /OVS/iso_pool, not the /OVS/iso_pool directory itself. 

D. The ISO file should be located under/OVS/seed_pool, not/OVS/iso_pool. 

E. The ISO file must have world-readable permission to be read by Oracle VM.

B. Suspend the virtual machine when not in use, then resume it when needed. 

C. Live migrate the virtual machine to a spare server when not in use, then live migrate it back when needed. 

D. Power off the virtual machine when not in use, then power it back up when needed. 

Answer:


Q45. A server with 16GB of RAM is only showing 8GB available after boot, but before running any virtual machines. What method will best find the issue? 

A. Look in /var/log/xen/xend.log for hardware-related messages. 

B. Use xm dmesg to see messages logged during the booting of the Xen hypervisor. 

C. Use dmesg to see messages logged during the booting of dom0. 

D. Look in /var/log/xen/xend-debug.log for hardware-related messages. 

Answer:

36. As you are grouping workloads into server pools, you decide you want to use network traffic as one of your criteria. Which answer describes how Network QoS (Quality of Service) might apply? 

A. throttles (restricts) the inbound and outbound network traffic for a virtual machine vif 

B. throttles (restricts) the inbound and outbound network traffic for a physical network interface 

C. throttles (unrestricts) the inbound and outbound network traffic for a virtual machine vif 

D. throttles (unrestricts) the inbound and outbound network traffic for a physical network interface

A. The ISO images should each be placed in their own subdirectory under/OVS/iso_pool. 

B. The ISO images should be joined into one larger ISO image using the M75cat command, then placed under a subdirectory of/OVS/iso_pool. 

C. The ISO images should all be placed under/OVS/iso_pool, using distinct names to differentiate them. 

D. The ISO images should be placed in one subdirectory under/OVS/seed_pool, named according to the vendor and distribution name. 

E. The ISO images should be placed in one subdirectory under/OVS/iso_pool, named according to the vendor and distribution name.

Answer:


Q48. What two steps are required to create a root repository in an Oracle VM server pool? 

A. Use the repos.py command with the --new option, along with either a device path or an nfs path. 

B. Use the repos.py command with the --new option, along with the UUID assigned to the repository. 

C. Use the repos.py command with the--new option, along with the UUID assigned to the repository and a device path. 

D. Use the repos.py command with the path. —root option, along with either a device path or an nfs path. 

E. Use the repos.py command with the--root option, along with the UUID assigned to the repository. 

Answer: A,E 


Q49. What requirements apply to shared storage on an HA Server Pool? 

A. Each server in the pool must have a connection to the shared storage, using NFS, ISCSI or a SAN Either ext3 or OCFS2 should be used to format the shared file system. 

B. Each server in the pool must have a connection to the shared storage, using NFS, (SCSI or a SAN. Either gfs or OCFS2 should be used to format the shared file system. 

C. t least one server in the pool must have a connection to the shared storage, using iSCSI or a SAN. Either ext3 or OCFS2 should be used to format the shared file system. 

D. Each server in the pool must have a connection to the shared storage, using iSCSI or a SAN. Only OCFS2 should be used to format the shared file system when using iSCSI or a SAN. 

E. Each server in the pool must have a connection to the shared storage, using NFS, iSCSI or a SAN. Only OCFS2 should be used to format the shared file system when using iSCSI or a SAN. 

Answer:


Q50. 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). 

Answer: A,B 

Explanation: 

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.
