Section 1 – Plan, Install and Upgrade VMware ESX/ESXi
- Objective 1.1 — Install VMware ESX/ESXi on local storage
If you want to test VMware vSphere before purchasing, what is the length of the Evaluation period available?
ESXi Installable and vCenter Server Setup Guide, ESXi 4.0 Installable, vCenter Server 4.0, page 97.
After the 60-day evaluation period expires, you are no longer able to perform some operations in vCenter Server and ESX/ESXi.
Under which of the following conditions would an administrator consider using the Boot from SAN option for the ESX Host (Choose Two)?
A.When concern exists that contention might occur between the Service Console and the VMkernel
B.To easily replicate the Service Console to a remote site
C.When using Microsoft Cluster Service
D.In diskless hardware configurations
VMware ESX 3.0.0 SAN Booting Disaster Recovery – Boot images stored on disk arrays can be easily replicated to remote sites where standby servers of the same HW type can boot quickly, minimizing the
negative effect a disaster can have to the business iSCSI SAN Configuration Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 52.
Boot from a SAN:
1. If you do not want to handle maintenance of local storage.
2. When you need easy cloning of service consoles.
3. In diskless hardware configurations, such as on some blade systems.
What is the size of a Virtual Machine .vswp file if defaults are taken for the VM reservations, limits, and shares?
A.The VM .vswp file is equal to the amount of virtual memory (VM available memory plus VM overhead)
configured for the VM when it was created
B.The VM .vswp file is set to zero length when the VM is created and grows as necessary
C.The VM .vswp file is equal to twice the amount of available memory configured for the VM when it was created
D.The VM .vswp file is equal to the amount of available memory configured for the VM when it was created
The default VM reservations, limits, and shares are shown below. Determining the right size for your VMware VMFS data stores.
The .vswp fileis a virtual swap file that equals the size of the memory assigned to a VM, minus any memory reservations assigned to a VM, which by default is zero.
Installing additional software in the ESX Service Console is supported in which of the following instances?
A.for improved utilization of the ESX host resources
B.for hardware management support
C.for graphical desktop access for administrative purposes
D.for enhanced virus protection
VMware ESX Server Third-Party Software in the Service Console, page 4
The only circumstance in which you might have to resort to running the software within the ESX
Server service console is when you require direct access to hardware.
An ESX Administrator plans to install additional supported components on the ESX Server that would increase the memory requirements for the Service Console. Which ESX Server partition would also need to be increased during installation as a result?
Mastering VMware vSphere 4, page 25.
‘As a general rule, swap files are created with a size equal to at least two times the memory allocated to the operating system. The installation process allocates a default amount of 300MB of memory for the Service Console; therefore, the default swap partition size would be 600MB. ‘
‘It might be necessary to increase the amount of memory granted to the Service Console…If additional third party applications are needed to run in the Service Console…then more memory may be needed…’
VCPCERT.com decides to use a license server for a newly installed Virtual Infrastructure. The infrastructure consists of one vCenter server and two ESX Server hosts, each with two dual core CPUs. DRS, VMware HA and VMotion will be used on all hosts. How many license files need to be installed on the license server?
VMware: Combining .lic license files.
As you may know, the license server for VI3 (provided by FlexLM) can only use 1 license file. This file is called vmware.lic and is stored (latest version) in C:\Program Files\VMware\VMware License Server.
What is the maximum number of VMkernel swap files that an ESX Server can have on a single VMFS volume?
A.1 per virtual machine
B.VMkernel swap files must be stored locally on the ESX Server
C.1 per virtual disk
Configuration Maximums VMware vSphere 4.0 and vSphere 4.0 Update 1, page 5.
Memory Maximums Table 4. Memory Maximums Item Maximum Swap files 1 per virtual machine
What is a requirement for enabling NIC teaming?
A.A physical NIC is linked to multiple virtual switches
B.All physical NICs must be of the same type.
C.Multiple physical NICs are linked to a single virtual switch
D.All virtual NICs must be of the same type.
Vmware Knowledge Base KB 1004088
To utilize NIC teaming, two or more network adapters must be uplinked to a virtual switch.
The NIC team used for the virtual machine network provides extra capacity as well as failover and keeps the portgroup connected to the network if one of the network adapters fails. The VMotion uplink is ideally connected to its own subnet along with other ESX Server host’s VMotion ports to separate its traffic from the virtual machine and Service Console traffic and maximize performance.
An additional network adapter can be uplinked to virtual switch 1 to provide for failover on the Service Console (management) interface, or to a new virtual switch 4 to provide for iSCSI or NFS storage (ideally on its own subnet).
A company plans to implement an ESX 4.0 / vCenter infrastructure that includes the following:
-three ESX Server host machines with four physical dual-core processors
-the ability to migrate running virtual machines (VMs) between these hosts without taking them offline
-multiple processor support for certain applications
What licensing is necessary to support these requirements?
A.1 vCenter server license, a 24-processor VMotion license, and a 24-processor ESX Server license
B.1 vCenter server license, a 12-processor VMotion license, and a 12-processor ESX Server license
C.3 vCenter server licenses, 3 VMotion licenses, and 3 ESX Server licenses
D.1 vCenter server license, 1 VMotion license, and an ESX Server license for each virtual processor for each running VM

VMware Multi-Core Pricing & Licensing Policy
How does this policy affect my licensing costs on servers with less than 6 cores per processor?
When upgrading your hardware to multi-core technology, you do not need to pay additional licensing fees for a processor with up to 6-cores per processor. For example, if you purchase a two-socket server with each socket populated with a 6-core processor, you need to purchase only two processor licenses of VMware vSphere or related products for that server.
How does this policy affect my licensing costs on servers with 8-cores per processor?
When upgrading your hardware to a server with 8-cores per processor you may upgrade your license or purchase a new license for VMware vSphere Advanced or Enterprise Plus that allows you to deploy the applicable software on up to 12-cores per processor
1. Three ESX Server host machines with four physical dual-core processors will therefore require 3 x 4 = 12 licenses
2. The ability to migrate running virtual machines (VMs) between these hosts without taking them offline requires VMotion, which is licensed as above, sop would require 12 licenses of an appropriate version of vSphere.
3. Multi-processor support for applications is based on physical processor availability, and is not sperately licensed
4. Each vCenter installation is separately licensed. Since this is a very small site, and there is no indication that additional vCenter servers will be installed, a single license is required for vCenter server.
During installation you manually create a local VMFS volume. What is a possible purpose for this volume?
A.service console swap files for over commitment of service console RAM
B.decentralized storage for all VMkernel swap activity
C.VMkernel swap files for locally configured virtual machines
D.storage for service console log files
Best Practices for vSphere (ESX 4) Service Console Partitions
The swap partition is used to supplement RAM if the service console runs out of physical memory. Therefore A is incorrect.
In-depth ESX Server service console partitioning and provisioning Because ESX Server’s Service Console is based on Red Hat Enterprise Linux, it places its log files in /var/log. Therefore D is incorrect.
The Role of Memory in VMware ESX Server 3, page 3.
When you power on a virtual machine, a corresponding swap file is created and placed in the same location as the virtual machine configuration file (.vmx file). The virtual machine can power on only when the swap file is available. Therefore C is incorrect.
Mastering Vmware vSphere 4, page 219.
Local storage is still used by default in vSphere ESX 4 installations as the ESX userworld swap (think of this as the ESX host swap and temp use). Therefore B is correct.
Which partition is required to store core dumps for debugging and for VMware technical support?
