QUESTION 22
What are two benefits that result from creating new virtual machines (VMs) using templates instead of creating blank VMs? (Choose Two.)
A.easier to upgrade and manage multiple VMs
B.faster deployment
C.less disk space used in the resulting VM
D.standardized base images
Answer: BD
Explanation:
VirtualCenter 2 Templates Usage and Best Practices, page 2 and 3.
The first and simplest reason for using virtual machine templates is efficiency. With templates, many repetitive installation and configuration tasks can be avoided. The result is a fully installed, ready to operate (virtual) server in less time than manual installation.
Templates are also used to help enforce consistency and standards. Deploying from templates, helps to enforce corporate standards such as including Antivirus and management software in any machine connected to the network.
QUESTION 23
VMware Converter Enterprise supports the following types of cloning (Choose Two):
A.Remote
B.Staged
C.Imaged
D.Local
Answer: AD
Explanation:
vCenter Converter Administration Guide vCenter Converter for vCenter Server 4.0, page 11.
When you clone remotely, you can access the source machine remotely, as long as it is running and accessible to the network. With local cloning, vCenter Converter runs on the source machine to perform the migration.
QUESTION 24
Which of the following ESX Server memory conservation techniques will always have the LEAST negative effect on the performance of a running VM?
A.use of the .vswp file
B.vmmemctl
C.Transparent Page Sharing
D.lowering the Reservation variable
Answer: C
QUESTION 25
Which of the following files are part of a typical virtual machine?
A.BIOS File (.nvram)
B.VMotion Transfer File (.vmt)
C.Configuration File (.vmx)
D.Virtual Disk File (.vmdk)
E.Hardware File (.svr)
Answer: ACD
Explanation:
VMware File Extensions
.VMDK — These files are the actual hard disk of the virtual machine itself, and tend to be the largest file within the folder. You can consider the size of this file to be roughly equivalent to the size of either the disk itself (if you’ve chosen to use preallocated disks) or the size of the data currently stored on that disk (if you use growable disks). [D above]
.NVRAM — Consider this file the BIOS of the virtual machine. [A above]
.VMX — With typically one VMX file per folder, this file holds the configuration information for the virtual machine in a text format. [C above]
.VMXF — This file, in XML format, includes additional information about the virtual machine if it has been added to a team. If a machine has been added to a team and then later removed, this file remains resident. This file can also be opened and read in a text editor.
.VMTM — For virtual machines actively participating in a team, this file stores information about that team membership.
.VMEM — These files, which contain a backup of the VMs paging file, are typically very small or non-existent when the virtual machine is powered off, but grow immediately to the size of configured RAM when the machine is powered on.
.VMSN and .VMSD — When snapshots are created for a virtual machine, these files are created to host the state of the virtual machine.
.VMSS — If you’ve suspended the state of your machine, this file contains the suspended state of that machine. These files typically only appear when virtual machines have been suspended.
.HLOG — If you have vMotioned the Virtual Machine, this file is created and can be safely deleted.
QUESTION 26
Guided consolidation allows you to perform the following tasks (Choose Three):
A.Analyze physical systems to determine performance characteristics
B.Gain an inventory of all model types of physical systems in your datacenter
C.Discover physical systems in your datacenter
D.Import performance information from a 3rd party tool for analysis
E.Consolidate physical systems by converting them to Virtual Machines
Answer: ACE
Explanation:
vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0, page 89.
VMware vCenter Guided Consolidation, … involves the following process
Find – You search for and select the physical systems in your datacenter that you want analyzed.
Analyze – Selected physical systems are analyzed and performance data on each selected system is collected. Generally, the longer the duration of the analysis phase, the higher the confidence in the vCenter Server’s recommendations.
Consolidate Performance data is compared to the resources available on the virtual machine host systems. The selected physical systems are converted to virtual machines and imported into vCenter Server on the recommended hosts where they are managed along with other components of your virtual environment
QUESTION 27
Guided consolidation shows you the following information after a successful analysis (Choose Three):
A.CPU Type
B.System Model
C.Machine Name
D.CPU Usage
E.Memory info and usage
Answer: CDE
Explanation:
vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0, page 95.
When analysis is complete, the following information appears:
Physical Computer – Displays the host name of the physical system being analyzed or imported. [C above]
CPU Info – Displays the number of CPUs and their clock speed.
Memory Info – Displays the amount of RAM on the system. [E above]
Status – Displays the progress of the analysis.
Confidence – Indicates the degree to which vCenter Server is able to gather performance data about the system and how good a candidate the system is based on the available data.
CPU Usage – Displays the system’s average CPU usage over time. [D above]
Memory Usage – Displays the system’s average memory usage over time. [E above]
QUESTION 28
Which of the following indicates how suitable an analyzed system is for Guided Consolidation?
A.Consolidation Factor
B.Suitability Metric
C.Performance Factor
D.Confidence Metric
Answer: D
Explanation:
vSphere Basic System Administration vCenter Server 4.0 ESX 4.0 ESXi 4.0, page 95.
After 24 hours of analysis, vCenter Server indicates a high level of confidence in its recommendations
QUESTION 29
What must be done to allow customization of Windows virtual machines that are deployed from templates?
A.The location of the sysprep.exe must be specified in config.ini.
B.Sysprep must be downloaded from Microsoft and installed on the vCenter server.
C.Nothing needs to be done as the vCenter installer automatically locates and installs Sysprep components.
D.A sysprep.inf file must be created in a text editor and imported using the customization wizard.
Answer: B
Explanation:
VMware VirtualCenter 1.0 Support Documentation
Install the required components on the Windows machine where the VirtualCenter management server is installed.
If you plan to customize a Windows guest operating system, you must first install the Microsoft Sysprep tools, (B).
