A company runs several instances of multi-threaded application that requires virtual machines to be configured
with multiple vCPUs.
Which metric is checked to determine if CPU contention exists on an ESXi 5.x host?
The percentage of time the world spent in wait state.
This %WAIT is the total wait time. I.e., the world is waiting for some VMKernel resource. This wait time includes
I/O wait time, idle time and among other resources. Idle time is presented as %IDLE.
The percentage of time the world was ready to run.
A world in a run queue is waiting for CPU scheduler to let it run on a PCPU. %RDY accounts the percentage of
this time. So, it is always smaller than 100%.
+Q: How do I know CPU resource is under contention?+
+A: %RDY is a main indicator. But, it is not sufficient by itself.+
Which vSwitch port group policy setting allows packets to be created by a virtual machine with different source
MAC addresses to MAC address?

B. Traffic shaping
C. Forged transmits
D. MAC address changes

An administrator is using Update Manager 5.0 to update virtual appliances in a vSphere environment. The
environment is using the vCenter Server appliance. The administrator is unable to remediate the vCenter
What would cause the remediation to fail?
A. Updating of the appliance can only be done if the vCenter Server Appliance has been
B. Remediation must be configured on the Appliance Administration page before use
C. Remediation of the vCenter Server Appliance with Update Manager is not supported
D. Remediation of the vCenter Server Appliance must be done from the PowerCLL
Which three configuration settings will be migrated when upgrading a host from ESX 4.x Classic to ESXi 5.x?
A. The NTP configuration in /etc/ntp.conf
B. The syslog configuration in /etc/syslog.conf
C. The hostname information in /etc/hosts
D. The time zone configuration in /etc/localtime
E. The name resolution Configruation in /etc/resolv.conf
11-28 – Question was modded to reflect the actual questions on the test.
What is the size of a virtual machine .vswp file if defaults are accepted for the virtual machine reservations,
limits, and shares?
A. The virtual machine. vswp file is equal to twice the amount of available memory configured for the virtual
machine when it was created.
B. The virtual machine. vswp file is equal to the amount of virtual memory (virtual machine available memory,
plus virtual machine overhead the virtual machine when it was created.
C. The virtual machine. vswp file is equal to zero length when the virtual machine is created and expands as
D. The virtual machine. vswp file is equal to the amount of available memory configured for the virtual machine
when it was created.
Which three features are only available when using a vNetwork Distributed Virtual Switch? (Choose three)
A. NetFlow Monitoring
B. 802.3ad Link Aggregation
C. Network I/O Control
D. Egress Traffic Shaping
E. IEEE 802.1p Qos tagging
Explanation: Removed Egress traffic shaping and added option E.

An iSCSI array is being added to a vSphere5 implementation. An administrator wants to verify that all IP
storage VMkernel interfaces are configured for jumbo frames.
What are two methods to verify the configuration? (Choose two)
A. Run the esxcli network IP interface list command
B. Run the esxcfg-vswitch -l command
C. View the VMKernel interface properties in the vSphere Client
D. View the Network Adapter properties in the vSphere Client

ESXCFG-VSWITCH is used in ESX Linux based, now using ESXCLI
Click the exhibit button.
An administrator has deployed a new virtual machine on an ESXi host. Users are complaining of poor
performance on the virtual machine performance tool display the result shown in the exhibit.
Which two might improve the user experience? (Choose two)
A. Add a vCPU to the virtual machine
B. Remove CPU affinity on the advanced CPU setting of the virtual machine
C. Migrate the virtual machine to another ESXi host
D. Remove the limit on the CPU settings of the virtual machine
Challeneged by Kre-den
48: A D
The picture shows CPU at 100% in VM, not CPU shortage on ESX server.
A,D – these 2 options both increase the amount of CPU allocated to VM
B,C – these 2 options change the physical CPU allocated to VM, but this was not the problem shown
Which two statements are about Unplanned Device Loss in a vSphere 5 environment?
A. It is condition where an ESXi host determines a device loss has occurred that was not planned.
B. Performing a storage rescan restores access to determine why device loss occurred.
C. It is a condition where an ESXi host is unable to determine why device loss occurred.
D. Performing a storage rescan removes the persistent information related to the device.

An administrator is creating a virtual machine that will be running “Windows 2008 Enterprise (64-bit). The
application to installed in the virtual machine requires eight vCPUs to run effectively. During installation, the
only available options are one, two, three, or four vCPUs.
What condition explains the available vCPU selections?
A. The virtual machine hardware version is 8.
B. The guest operating system for the virtual machine is 64-bit
C. The ESXi host has two AMD dual-core CPUs
D. The ESXi host has two Intel dual-core CPUs
