The Bottom Line - Mastering VMware vSphere 5.5 - page 756

Master It You have multiple vCenter Server instances within your environment that
you wish to manage with the vCenter Web Client. Do you need to install a separate Web
Client service for each vCenter server?
Solution No. Each vCenter Server instance can be registered to a single Web Client.
When a user logs into the Web Client, only the vCenter objects they have rights to will be
visible.
Use vCenter Server's management features. vCenter Server provides a wide range of
management features for ESXi hosts and VMs. These features include scheduled tasks, host
proi les for consistent coni gurations, tags for metadata, and event logging.
Master It Your manager has asked you to show him all of the VMs and hosts that be-
long to the accounts department but is not interested in seeing the test servers. What tools
in vCenter Server will help you in this task?
Solution Provided you have vCenter Server coni gured with the appropriate tags and
categories, a simple search on his requirements should provide enough information for
your manager.
Chapter 4: vSphere Update Manager and the vCenter
Support Tools
Install VUM and integrate it with the vSphere Client. vSphere Update Manager (VUM)
is installed from the VMware vCenter installation media and requires that vCenter Server
has already been installed. Like vCenter Server, VUM requires the use of a backend database
server. Finally, you must install a plug-in into the vSphere Client in order to access, manage,
and coni gure VUM.
Master It You have VUM installed, and you've coni gured it from the vSphere Client on
your laptop. One of the other administrators on your team is saying that she can't access
or coni gure VUM and that there must be something wrong with the installation. What is
the most likely cause of the problem?
Solution The most likely cause is that the VUM plug-in hasn't been installed in the
other administrator's vSphere Client. The plug-in must be installed on each instance of
the vSphere Client in order to be able to manage VUM from that instance.
Determine which ESX/ESXi hosts or VMs need to be patched or upgraded. Baselines
are the “measuring sticks” whereby VUM knows whether an ESX/ESXi host or VM instance
is up-to-date. VUM compares the ESX/ESXi hosts or VMs to the baselines to determine
whether they need to be patched and, if so, what patches need to be applied. VUM also uses
baselines to determine which ESX/ESXi hosts need to be upgraded to the latest version or
which VMs need to have their VM hardware upgraded. VUM comes with some predei ned
baselines and allows administrators to create additional baselines specii c to their environ-
ments. Baselines can be i xed—the contents remain constant—or they can be dynamic, where
the contents of the baseline change over time. Baseline groups allow administrators to com-
bine baselines and apply them together.
Master It In addition to ensuring that all your ESX/ESXi hosts have the latest criti-
cal and security patches installed, you need to ensure that all your ESX/ESXi hosts
