Oracle VM 2 for x86 Essentials

Question No: 31

When vitalizing a cluster of Windows 2003 servers on Oracle VM, which virtualization technique should be used?

  1. Use PV with Microsoft#39;s Windows 2003 64-bit with a paravirtualized kernel

  2. Use HVM with a standard distribution of Windows 2003 and PV drivers.

  3. Use emulation with the IOEMU drivers for better I/O performance.

  4. Oracle VM does not support Windows 2003 Server. Use VirtualBox instead.

  5. Oracle VM does not support Windows 2003 Server. Use Containers instead.

Answer: B Explanation:

I told you before about the HVM for Windows 2003

Question No: 32

A customer is running an existing server farm of open source Xen servers running the same version of Xen as Oracle VM 2.2. The customer would like to manage these servers with Oracle VM.

What is the best reason that this will not be possible?

  1. Oracle VM#39;s Xen implementation uses a different disk format for virtual machines than open source Xen, so live migration of virtual machines will not work between the existing Xen implementation and Oracle VM.

  2. Oracle VM employs a layer of technology on top of Xen that enables remote management through Oracle VM Manager or Oracle Enterprise Manager. The existing Xen servers are incapable of communicating in this manner.

  3. Oracle VM uses a forked Xen distribution, so although the version numbers are the same, the behavior of the virtual machines at run time will be different.

  4. Oracle VM uses a highly proprietary protocol format for Live Migration that enables strongencryption. Standard Xen servers will not be able to live migrate to the Oracle VM servers, or vice versa.

Answer: B

Question No: 33

What two attributes of a virtual machine are not available on the Oracle VM Manager Home screen when the virtual machine is currently powered down?

  1. Memory Size

  2. Server Name

  3. VNC Port

  4. Server Pool Name

  5. Owner

  6. Number of Virtual CPUs

Answer: B,C Explanation:

If you properly shutdown the virtual machine then you will not get the Server Name surely . So that one correct answer is Server Name. Let’s find another correct answer.

Ensurepass 2018 PDF and VCE

Follow the picture and you will find that the virtual machines which are shutdowed and there is available of Owner and Server Pool Name. But if the machine is not up there so how will you get the vnc port for that machine :D?

Correct answer is B and C.

Which two statements describe Oracle Validated Configurations?

  1. Oracle Validated Configurations provide testing of a quot;complete component stackquot; andrecommendations on versions, settings, and fixes for the particular stack (software, hardware, and storage) based on running workloads in Oracle#39;s or a partner#39;s test lab.

  2. Oracle Validated Configurations are a mandatory step in Oracle#39;s certification process.

  3. Oracle Validated Configurations are working samples of hardware and software configurations in an Oracle VM environment.

  4. All validated configurations must be run in Oracle#39;s lab.

  5. Oracle Validated Configurations are potential examples of hardware and software configurations whose specifications are validated by Oracle.

Answer: E

Question No: 35

Which three attributes of an existing virtual disk can be changed using Oracle VM Manager?

  1. Virtual Disk N

  2. Virtual Disk Size

  3. Hard Drive Type

  4. QoS Enabled

  5. Priority Class

Answer: B,D,E Explanation:

For an existing virtual disk you can change the size vmware-vdiskmanager -x 80GB mydisk.vmdk

From the Virtuladisk Manager scrren you can change the QoS enable and disable and the Priority class you can change.

Question No: 36

What command(s) will create a new 10 GB virtual disk named Apps, and attach it to a virtual machine named Test?

  1. sd new -d 10240 -n Apps vm sd attach -n Test -d Apps

  2. sd new -d 10240 -n Apps sd reg -n Apps vm

    sd attach -n Test -d Apps

  3. vm disk add -n Test -d Apps -S 10240

  4. vm sd attach -n Test -d Apps -S 10240

  5. vm disk add -n Test -d Apps -S 10240 vm sd attach -n Test -d Apps

Answer: E

Question No: 37

When a domain is live migrated, what resources are migrated between the source and target servers?

  1. First the VM files are migrated between the servers, then the memory, then the CPU registers.

  2. First the VM files are migrated between the servers, then the memory.

  3. First the memory is migrated between the servers, and then the CPU registers.

  4. Only memory is migrated.

Answer: A Explanation:

live migration – is similar to warm migration, except that the guest is not suspended during transmission. Instead, the LDoms manager keeps track of memory changed while state is being transmitted, and then makes followup passes to retransmit data changed state information. A brief pause is used at the end to transmit residual changed state. This

method is typical for virtual machine systems that provide live guest migration.

Question No: 38

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?

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

  2. Run xm dmesg to see hardware errors in the guest.

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

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

Answer: A,B

Question No: 39

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?

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

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

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

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

Answer: B

Question No: 40
