Questions # 1:

In a para-virtualized environment which network drivers are used in dom0 and guest VM to communicate between one another?

Options:

The guest uses netfront and dom0 uses netbk.

The guest uses netbk and dom0 uses netfront.

The guest uses netfront and dom0 uses native drivers.

Both the guest and dom0 uses native frivers.

Both the guest and dom0 uses emulated drivers.

Expert Solution

Questions # 2:

Which two are characteristics of block I/O in a fully hardware virtualized configuration?

Options:

The virtual machine I/O path only uses the block device driver from dom0.

The virtual machine relies onemulation of the hardware in dom0 for block I/O.

The virtual machine I/O path includes the native block device drivers from the guest operatingsystem.

The virtual machine does not need a block device driver.

The virtual machine must provide emulation of the hardware through its own IOEMU drivers.

Expert Solution

Questions # 3:

Which three statements concerning Oracle virtual assembly builder are correct?

Options:

All components of Oracle virtual assembly builder are accessible from a tab in OracleVM manager.

Oracle virtual assembly builder manage the full life cycle of assemblies including introspection, configuration, preparation and development.

Standard resources (such as mail, printer, identity management etc.) all servers must be manually configured of the e-submit development is complete.

Assembles are comprised of interrelated software appliances along with metadata catalog that describes their relationship.

Assemblies promote rapid development, lower operation cost and simple implementation of the best practices.

Options:

VLAN

Port authentication

Spanning Tree

Link Aggregation

Dedicated link

Expert Solution

Questions # 5:

What is the purpose of virtual machine network types?

Options:

Provide a separate network segment use for the secure live migration of VM.

Provide anetwork capable of managing all virtual machines through Oracle VM manager.

Provide a separate network for all users and application traffic to/from virtual machines.

Allow virtual machines to access all virtual disks images without interfering withthe cluster heartbeat.

Allow Oracle VM manager to monitor the status of all virtual machines.

Expert Solution

Questions # 6:

A virtual machine is copied onto portable media and transferred to another machine In a different server pool. The virtual machine is then run on the new host, but it falls to boot. What are two potential problems?

Options:

The virtual machine was not exported properly using the Oracle VM Manager.

The virtual machine configuration file needs to be changed to update the new pathsto its virtualdisks.

The virtual machine configuration file lists bridges that do not exist on the new host.

The virtual machine has not been registered with Oracle VM yet.

Expert Solution

Questions # 7:

There is an issue booting into a virtual machine. The log files show that there is an issue during the Linux boot process of the guest. What two methods will best help determine the problem?

Options:

Use xm console to attach to the guest while it is booting and look for the specific error.

Run xm dmesg to see hardware errors in the guest.

Run xm info to see the list of devices being attachedto the virtual machine.

xm block-attach the disk to another virtual machine to inspect the file system and check module loading issues.

Expert Solution

Questions # 8:

When setting up an iSCSI repository, what three steps must be completed before running the repos.py commands?

Options:

The iSCSI LUN must be formatted with the OCFS2 file system.

Theiscsi-adm service must be installed and running.

The iSCSI daemon must be installed and running.

Multipathing must be configured and the multipath daemon must be running.

The iSCSI LUNs must be mapped to local devices.

Expert Solution

Options:

brctl addif xenbr0 eth0

brctl addbr xenbr0 eth0

ifconfig add xenbr0 eth0

netstat -a xenbr0 eth0

if up xenbr0 -a eth0

Questions # 10:

You are installing the Solaris 11 OVM template downloaded from Oracle edelivery site. You have previously imported and installed these templates with success on another server. However, when you attempt to start the newly imported virtual machine it through an error indicating that HVM is required for this operation and virtual machine fails to start. There are currently two Para-virtualized VM are already running on the Oracle VM server where the failure is occurring. Which two explanations and situations might remedy this problem?

Options:

Download might be corrupt. Download the template again and attempt the import or use a copy of the template that was previously imported.

Virtual machine is configured improperly. Navigate to edit the virtual machine setting. In the Oracle VM manager on the first pagechange the domain type from XEN PVM to XEN HVM using the pull down menu and then start the machine.

Hardware virtualized CPU extension VT-X or AMD-V are not enabled is the machine BIOS setting. Enable the feature in the BIOS for virtualization support and to enable the virtual machine to start.

The imported template is not compatible with the OVM server. Locate the vm.conf file for the Solaris VM edit the file and add the line “builder=HVM” save the file and start the VM.

Server does not support the hardware virtualization. Build the Solaris VM on the server that support hardware virtualization.
