QUESTION 34
Once vCenter 4.x has been installed, a License Server is required in which of the following instances?
A.To support ESX 3.5 Hosts
B.A License Server is no longer required
C.To support ESXi 4.x Hosts
D.A License Server is always required
Answer: A
Explanation:
vSphere uses a new centralized license reporting and management structure, which means that if all ESX hosts are upgraded to version 4, no license server or host license file is needed. ESX 3.5 hosts still require access to a license server, which can be used by the vSphere Virtual Center by configuring the License Server option under Administration-Server Settings.
QUESTION 35
Which ports does VMware Update Manager use? Select five.

J.9084
Answer: DEFIJ
Explanation:
The CORRECT Answer is: 80, 443, 902, 8084, 9084, possibly 1433 and 1521
Port 903 is not used… see list below.
80 = Obtain metadata for the updates

443 = Obtain metadata for the updates
Host to VUM Server
vCenter Server to VUM Server
902 = Push patches and updates from VUM
1433 = To Microsoft SQL Server
1521 = To Oracle connectivity
8084 = SOAP between components of VUM
9084 = VUM Web Server. Accessed
903 = VI/vSphere Client to VM Console
VM Remote VM Console
The Update Manager Web server listens on 9084 TCP if the default is not changed during the installation.
The Update Manager SOAP server listens on 8084 TCP if the default is not changed during the installation.

QUESTION 36
Which of the following are valid use cases for vCenter Server Linked Mode for a vCenter server installed on a 32-bit guest (Choose Two)?
A.An administrator wants to migrate virtual machines between vCenter Servers
B.An administrator wants to define permissions once and have them applied to all vCenter Servers
C.An administrator wants to view Service Status for all vCenter Server inventory objects from one Client
D.The environment has 400 ESX Hosts
Answer: BC
Explanation:
vSphere Basic System Administration : Getting Started : Using vCenter Server in Linked Mode : Monitor vCenter Server Services Monitor vCenter Server Services
When you are logged in to a vCenter Server system that is part of a connected group, you can monitor the health of services running on each server in the group.
The vCenter Service Status screen enables you to view the following information:
A list of all vCenter Server systems and their services, and vCenter Server plug-ins.
The status of all listed items.
The date and time when the last change in status occurred.
Any messages associated with the change in status.
Incorrect answer: The environment has 400 ESX Hosts 32-bit OS for vCenter will only support 200 Hosts and 2000 powered on VM’s ( 3000 registered ).
A single instance of vCenter Server 4.0 manages up to 300 hosts and 3000 virtual machines and with Linked Mode you can manage up to 1,000 hosts and 10,000 virtual machines across 10 vCenter Server instances.

Configure an Oracle Connection for Local Access
VMware recommends that the vCenter Server database be located on the same system as vCenter Server.
Procedure
2. Configure the TNS Service Name option in the ODBC DSN. The TNS Service Name is the net service name for the database to which you want to connect. You can find the net service name in the tnsnames.ora file located in the NETWORK\ADMIN folder in the Oracle database installation location.
Configure an Oracle Connection for Remote Access A vCenter Server system can access the database remotely.
6. Use a text editor or the Net8 Configuration Assistant to edit the tnsnames.ora file located in the directory C:\Oracle\Oraxx\NETWORK\ADMIN, where xx is either 10g or 11g.
Add the following entry, where HOST is the managed host to which the client must connect.
VPX =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL=TCP)(HOST=vpxd-Oracle)(PORT=1521))
