Questions # 31:

A customer decides to use 2 large servers to load balance a mix of large and small virtual machines. Each server has 64GB of RAM and 8 quad-core CPUs. There are 14 virtual machines, 6 of which use 12GB of virtual memory and 16 vCPU each, and the remaining 8 use 2GB and 4 vCPUs each. What two issues will the customer likely discover when one of the servers fails?

Options:

Not all of the virtualmachines on the failed server will be able to restart on the remaining serverdue to lack of vCPUs.

Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of memory.

Live migration will be unavailable until the second server is restored.

Not all of the virtual machines on the failed server will be able to restart on the remaining serverdue to lack of vNICs.

Not all of the virtual machines on the failed server will be able to restart on theremaining serverdue to lack of shared storage.

Questions # 34:

When converting hardware virtualized machine to full PV, the guest falls to boot. What line in vm.cfq is likely leftover from the HVM configuration?

Options:

vnclisten = '0.0.0.0'

pae =1

builder=’hvm’

serial=’pty’

Answer

Explanation

My suggestion is to use builder=’hvm’ because it works fine for once I have failed to booting the server but when I made it builder=’hvm’ it booted fine. Another thing is if you use linux os as amother os then you can leftover this builder=’hvm’ but if you use windows2003 then you have to use builder=’hvm’.

Questions # 35:

Options:

The server where the template is deployed should have enough local disk to store the virtual disk images.

The server mustbe in the clustered server pool.

The server must have more memory then the host that was converted.

The P2V converted virtual machine must have a unique name.

The server in the server pool must have hardware virtualized support (have intel VT-X orAMD-v chip feature).

Answer

Questions # 36:

What two steps can be used to create a highly available storage repository?

Options:

Turn on HA in the storage pool to create a redundant backup of virtual machines hosted in thatstorage pool.

Use network bonding to create multiple redundant paths to an iSCSI LUN.

Use multipathing to create multiple storage network paths toa SAN LUN.

Use Oracle Clusterware to create multiple paths to a SAN LUN.

Use Oracle Clusterware to create each storage repository on a different storage network.

Answer

A, D

Questions # 37:

Which statements about Oracle VM agent architecture are accurate?

Options:

Oracle VM agent are daemon processes that automatically initiated when an Oracle VM server is booted.

Oracle VM manager always uses SSH command directly to dom0 on each Oracle VM server when the agent does not respond.

Oracle VM manageris capable of communicating with multiple server pools master server.

Multiple server pools master server should be running 1 active and 1 standby in each server pool to provide redundancy and fault tolerance.

All communication from one agent to other agent with in a server pool routed through the Oracle VM manager.

You can specify using Oracle VM manager which Oracle VM server assist this server pool as master server.
