QUESTION 34
A developer wishes to disable logging for a number of virtual machines used for testing purposes, in order to maximize available datastore space. The virtual machines reside on an ESX Host managed by vCenter Server. Which of the following methods can be used to disable virtual machine logging?
A.Manually edit each virtual machines .vmx file and set logging=false
B.From the Configuration tab for the ESX Host running the virtual machines, choose Advanced Settings. Set the Disable Logging parameter to Yes
C.Edit the settings for each virtual machine. Under Options > Advanced > General, uncheck Enable Logging
D.Connect a vSphere Client to vCenter Server. Under the Administration drop-down, check Disable Virtual Machine Logging
Answer: C
Explanation:
The screen shot below shows how to enable or disable logging.
QUESTION 35
When configuring the NTP server with MSCS clustered virtual machines, the best practice is ?
A.Synchronize domain controllers and cluster nodes with a common NTP server, and disable host based time synchronization in the guest.
B.NTP should not be used in conjunction with MSCS clustered virtual machines.
C.Synchronize domain controllers and cluster nodes with a common NTP server and enable host based time synchronization in the guest.
D.Enable host based time synchronization for domain controllers, cluster nodes and guest virtual machines.
Answer: A
Explanation:
Setup for Failover Clustering and Microsoft Cluster Service ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 10.
Synchronize domain controllers and cluster nodes with a common NTP server, and disable host based time synchronization when using clustering in the guest.
QUESTION 36
Establishing a Virtual Machine memory reservation guarantees (Choose Two)?
A.Minimum virtual memory guaranteed to the Virtual Machine while the VM is running
B.Physical memory for the VMkernel to start the Virtual Machine
C.Minimum physical memory guaranteed to the Virtual Machine while the VM is running
D.Virtual memory for the VMkernel to start the Virtual Machine
Answer: BC
Explanation:
vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 24.
Reservation is a guaranteed lower bound on the amount of physical memory that the host reserves for the virtual machine, even when memory is overcommitted. [C above]
QUESTION 37
What are two benefits of Virtual Compatibility Mode for RDMs? (Choose Two.)
A.passes native SCSI commands to underlying hardware
B.provides advanced file locking for data protection
C.provides snapshot capability
D.provides virtual-to-physical clustering capability
Answer: BC
Explanation:
vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0, page 121.
Virtual mode for an RDM specifies full virtualization of the mapped device. It appears to the guest operating system exactly the same as a virtual disk file in a VMFS volume. The real hardware characteristics are hidden. Virtual mode enables you to use VMFS features such as advanced file locking and snapshots.
QUESTION 38
Which two virtual machine (VM) elements are available from the VirtualCenter Web Access Console, but not the ESX Server Web Access Console? (Choose Two)
A.VM Console
B.VM Alarms
C.VM Tasks
D.VM Events
Answer: BC
QUESTION 39
Which statement is true about transparent page sharing?
A.It only works with Windows.
B.It is the process of collecting unused memory from the guest OS and returning it to the VMkernel.
C.It is the method of eliminating duplicate pages of memory allocated to multiple virtual machines.
D.It only works with supported guest OS.
Answer: C
Explanation:
vSphere Resource Management Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 74
For example, several virtual machines might be running instances of the same guest operating system, have the same applications or components loaded, or contain common data. In such cases, ESX/ESXi systems use a proprietary transparent page-sharing technique to securely eliminate redundant copies of memory pages.
QUESTION 40

B.create a virtual switch
C.add a virtual disk to a virtual machine
D.add a VMFSdatastore
Answer: C
