QUESTION 16
Which of the following are prerequisites for installing vCenter Server (Choose Three)?
A.The system vCenter is installed on can be in a workgroup or a domain
B.The system vCenter is installed on must be a physical server
C.The system vCenter is installed on must have a Static IP address or be registered with DNS if using DHCP
D.The system vCenter is installed on can be a virtual machine or physical server
E.The system vCenter is installed on must belong to a domain
Answer: CDE
Explanation:
ESX and vCenter Server Installation Guide, ESX 4.0, vCenter Server 4.0 Page 16, 83-84.
The vCenter Server system is a physical machine or virtual machine with access to a supported database. [D above]
The system that you use for your vCenter Server installation must belong to a domain rather than a workgroup. If assigned to a workgroup, the vCenter Server system is not able to discover all domains and systems available on the network when using such features as vCenter Guided Consolidation Service. [E above]
This paragraph is highly confusing, as it contradicts itself. However, in fact vCenter Server can be installed to a system residing in a workgroup, as shown below.
vCenter Server, like any other network server, should be installed on a machine with a fixed IP address and well-known DNS name, so that clients can reliably access the service. If you use DHCP instead of a static IP address for vCenter Server, make sure that the vCenter Server computer name is updated in the domain name service (DNS). [C above]
QUESTION 17
An administrator is installing vCenter in a virtual machine. The selected database is Microsoft SQL Server 2005. Which of the following actions must be taken before vCenter is installed (Choose Two)?
A.The Microsoft SQL Native Client should be removed
B.If the guest OS is Windows XP, MDAC 2.8 SP1 must be applied
C.If the guest OS has MSXML Core Services 6.0 installed, it must be removed
D.The Microsoft SQL Server Client should be removed
Answer: BC
Explanation:
ESX and vCenter Server Installation Guide ESX 4.0 vCenter Server 4.0, page 72.
Table 10-1. Configuration and Patch Requirements
Database Type:
* Microsoft SQL Server 2005
Patch and Configuration Requirements:
* For Microsoft Windows XP, apply MDAC 2.8 SP1 to the client. Use the SQL Native Client driver (version 9.x) for the client.
* Ensure that the machine has a valid ODBC DSN entry.
* If Microsoft SQL Server 2005 is not already installed and the machine has MSXML Core Services 6.0 installed, remove MSXML Core Services 6.0 before installing Microsoft SQL Server 2005.
QUESTION 18
During the installation of vCenter Server, if you choose Join Group, which of the following actions is taken?
A.The vCenter Server is joined to a Linked Mode group
B.The vCenter Server is configured for VMware Fault Tolerance
C.The vCenter Server is clustered with an existing vCenter Server for high availability
D.The /etc/group file on ESX Hosts managed by vCenter Server are configured for vpxuser authentication
Answer: A
Explanation:
ESX and vCenter Server Installation Guide, ESX 4.0, vCenter Server 4.0, page 91.
Install vCenter Server 10. Select Create a standalone VMware vCenter Server instance or Join Group and click Next. Join a Linked Mode group to enable the vSphere Client to view, search, and manage data across multiple vCenter Server systems.
QUESTION 19
An administrator is installing a vCenter Server to manage 10 ESX hosts and 100 virtual machines. Approximately how much additional space is required to increase the statistic collection level to maximum for all collection periods compared to a standard installation?
A.4GB
B.6GB
C.1GB
D.2GB
Answer: B
QUESTION 20
Which of the following are valid reasons for deploying vCenter Server in a virtual machine (Choose Three)?
A.vCenter Server must be deployed as a virtual machine to be migrated using VMotion
B.vCenter Server must be deployed as a virtual machine to back it up using vCenter Data Recovery
C.vCenter Server must be deployed as a virtual machine to be protected by High Availability
D.vCenter Server must be deployed as virtual machines to join a Linked Mode group
E.vCenter Server must be deployed as a virtual machine to support failover using Site Recovery Manager
Answer: ABC
QUESTION 21

A.700MB
B.1GB
C.500MB
D.100MB
E.340 MB
Answer: E
QUESTION 22
Suppose you have 10000 Virtual Machines across 2 Datacenters, with approximately 5000 Virtual Machines in each Datacenter. What is the minimum number of vCenter installations and vNetwork Distributed Switches required to support this configuration (Choose Two)?
A.1 vCenter Server
B.2 vNetwork Distributed Switches per Datacenter
C.2 vCenter Servers
D.1 vNetwork Distributed Switch per Datacenter
Answer: BC
Explanation:
Configuration Maximums VMware® vSphere 4.0 and vSphere 4.0 Update 1, page 6, 7.
Table 5. Networking Maximums
Total virtual network switch ports per host (vDS and vSS ports) 4096
Distributed virtual network switch ports per vCenter 6000
Since there are approximately 5000 VMs per Datacenter, 2 vNetwork Distributed Switches per Datacenter are required, (and would need to be split amongst 2 or more hosts), hence B.
Table 7. vCenter Server Maximums
Powered on virtual machines (32?bit OS server) 2000
Registered virtual machines (32?bit OS server) 3000
Powered on virtual machines (64?bit OS server) 3000
Registered virtual machines (64?bit OS server) 4500
Since, there are 5000 VMs per Datacenter, either 2 vCenter 64?bit OS servers are required per datacenter, (regardless of whether the VMs are powered on simultaneously or not) or 2 or 3 vCenter 32?bit OS servers are required per datacenter (3 if more than 4000 machines are powered on simultaneously). Therefore C is required.
QUESTION 23
An administrator is installing vCenter. The selected database is Oracle 11g. Which of the following steps are required to configure the database for use with vCenter (Choose Two)?
A.Configure an Oracle Connection for Local or Remote Access
B.Configure an Oracle Database User
C.Use a Script to Create a Local or Remote Database
D.Use a Script to Create the Oracle Database Schema
Answer: BC
Explanation:
ESX and vCenter Server Installation Guide ESX 4.0, vCenter Server 4.0, page 78-79.
Configure Oracle Databases
If you use an Oracle database for your vCenter Server repository, you need to configure your database to work with vCenter Server.
Use a Script to Create a Local or Remote Oracle Database
1. When you use an Oracle database with vCenter Server, the database must have certain table spaces and privileges. To simplify the process of creating the database, you can run a script. If you do not use this script, you can create the database manually. [C above].
Configure an Oracle Database User If you plan to use an Oracle database when you install vCenter Server, you must configure the database user. [B above].
QUESTION 24
You have decided to install vCenter on an existing Windows Server running an application that is accessed through standard HTTP and HTTPS connections, ports 80 and 443.
What will you need to do in order to successfully deploy vCenter?
A.No additional action is required
B.You must specify alternate vCenter Web Service ports during installation and manually specify the alternate ports when connecting with the vSphere Client.
C.You must move the application to another server but keep IIS installed and running on ports 80 and 443 for use with SDK clients.
D.You must change the vCenter Web Service port to 905 if SDK clients will be used.
Answer: B
Explanation:
ESX and vCenter Server Installation Guide, ESX 4.0, vCenter Server 4.0, page 19 and 91.
Install vCenter Server – Procedure.
12. Enter the port numbers that you want to use or accept the default port numbers and click Next.
vCenter Server requires port 80 for direct HTTP connections. Port 80 redirects requests to HTTPS port 443.
This is useful if you accidentally use http://server instead of https://server.
The vCenter Server system also uses port 443 to listen for data transfer from the vSphere Web Access Client and other SDK clients.
If you use another port number for HTTPS, you must use <ip-address>:<port> when you log in to the vCenter Server system.
QUESTION 21 is missing reference. And Q22 is out of date because vcenter now support 10000 Powered on VMs and a dvSwitch support 20000 ports.
