QUESTION 5
An administrator is assigning a user the Content Library administrator role. The user will only be creating the library for a
single vCenter Server. What is the lowest level of the permission heirarchy that this role can be granted to the user and
still allow them to create a Content Library?
A. Global
B. Datacenter Folder
C. Virtual Center
D. Datacenter
Correct Answer: A
To let a user manage a content library and its items, an Administrator can assign the Content Library Administrator role
to that user as a global permission. The Content Library Administrator role is a sample role in the vSphere Web Client.
Users who are Administrators can also manage libraries and their contents. If a user is an Administrator at a vCenter
Server level, they have sufficient privileges to manage the libraries that belong to this vCenter Server instance, but
cannot see the libraries unless they have a Read-Only role as a global permission.

QUESTION 12
An administrator notices that 8 out of 10 virtual machines have memory ballooning and swapping. However, virtual
machine 9 is not ballooning or swapping and virtual machine 10 is not ballooning but is swapping. Which two statements
explain the behavior of virtual machine 9 and virtual machine 10? (Choose two.)
A. Virtual machine 9 has a 100% memory reservation.
B. Virtual machine 10 has a memory limit configured.
C. Virtual machine 9 has memory shares set to HIGH.
D. Virtual machine 10 does not have Vmware Tools enabled or installed.
Correct Answer: AD
It seems that VM 9 has 100% memory reservation and VM 10 has a memory limit configured.
QUESTION 13
A user notifies an administrator that Content Libraries are not visible. What is a possible solution?
A. Assign the user the read-only role at the global permission level.
B. Assign the user the read-only role at the vCenter Server root level.
C. Assign the user the read-only role at the vCenter Server data center level.
D. Assign the user the read-only role at the vCenter Server cluster level.
Correct Answer: A
The direct parent for content libraries is the global root. This means that if you set a permission at a vCenter Server level
and propagate it to the children objects, the permission applies to data centers, folders, clusters, hosts, virtual
machines, and so on, but does not apply to the content libraries that you see and operate with in this vCenter Server
instance. To assign a permission on a content library, an Administrator must grant the permission to the user as a global
permission. Global permissions support assigning privileges across solutions from a global root object.

QUESTION 14
Which minor badge items make up the Efficiency badge score for an ESXi host in vCenter Operations Manager?
A. Workload, Anomalies, Faults
B. Workload, Stress, Density
C. Time Remaining, Capacity Remaining
D. Reclaimable Waste, Density
Correct Answer: D
The third major badge that vC Ops reports is Efficiency. We all moved to virtualization in hopes of achieving greater
efficiencies but there are varying degrees of efficiency so vC Ops is here to help ensure that you maximize the efficiency
of your virtual infrastructure. The efficiency badge score is a weighted combination of Reclaimable Waste and Density.

QUESTION 15

VMware certificate authority; you can make the VMCA an intermediate certificate authority. Likewise, you can provision
your own certificates.
QUESTION 16
An administrator is performing a silent automatic update of VMware Tools on a Windows virtual machine. What syntax
needs to be entered into the Advanced Options box?

B. –prefix=/usr/local,/usr/lib,/usr/doc –silent
C. –prefix=c:\Windows,c:\VMtools –silent
D. /fs /v “/qn+” /l “c:\Windows\filename.log”

One way to determine the component values to use is to run the interactive VMware Tools installer with full logging
turned on, select the components that you want installed, and then search the log files for the ADDLOCAL and
REMOVE properties. The log files show the names used by the program.

Correct Answer: BC
Of course, ESXi host upgrades preserve existing SSL certificate and it also have assigned SSL certificates from VMCA
during the installation process.
