When attempting to remove a host from a vSphere Distributed Switch (vDS), an administrator observes the error message:
The resource ’16’ is in use
What are two reasons why this error would be displayed? (Choose two.)
Vmkernel network adapters on the vDS are in use.
Virtual machine network adapters are connected to the vDS.
Network I/O Control has been configured on the vDS.
There is active network traffic on the vDS.

A user notifies an administrator that Content Libraries are not visible. What is a possible solution?
Assign the user the read-only role at the global permission level.
Assign the user the read-only role at the vCenter Server root level.
Assign the user the read-only role at the vCenter Server data center level.
Assign the user the read-only role at the vCenter Server cluster level.
Answer: A Explanation:
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.

A virtual machine is exhibiting these symptoms:
->Memory usage is constantly high (94% or greater) or constantly low (24% or less).
->Free memory is consistently 6% or less and swapping frequently occurs
Which three solutions could correct this problem? (Choose three.)
Verify that Vmware Tools is installed on each virtual machine.
Decrease the memory reservation setting, if higher than active memory.
Add physical memory to the host.
Disable the balloon driver in each virtual machine.
Create a memory limit for each virtual machine.
Answer: A,B,C Explanation:
Make sure Vmware tools are installed on each VM. To weed out the problem, decrease the memory reservation setting if it is higher than active memory or add physical memory to the host to increase its capacity.

An administrator has a virtual machine configured with the following settings:
->ESXi version: 5.1
->CPU: vCPUs 6
->Hardware version: 7
->VMware Tools: Installed
Which two actions must the administrator take in order to utilize vNUMA? (Choose two.)
Upgrade the ESXi host to vSphere 5.5 or later.
Upgrade to Virtual Hardware version 8.
Configure numa.vcpu.min to 5
Configure numa.vcpu.min to 6
Answer: B,C Explanation:
vNUMA can be used by upgrading to virtual hardware version 8. To enable vNUMA on 8 way or smaller VMs, modify the numa.vcpu.min setting.

An administrator wants to select a Host Power Management Policy for an ESXi 6.x host that will disable most hardware power management features.
Which Host Power Management Policy should be selected to meet this requirement?
Question No: 126 – (Topic 7)
An administrator is troubleshooting network communications between the vCenter Server and the ESXi 6.x host.
Which log shows the interaction events between these components?
Answer: C Explanation:
When an ESXi 5.1 / 5.5 host is managed by vCenter Server 5.1 and 5.5, two components are installed, each with its own logs:
->/var/log/vpxa.log: vCenter Server vpxa agent logs, including communication with vCenter Server and the Host Management hostd agent.
->/var/log/fdm.log: vSphere High Availability logs, produced by the fdm service.
Question No: 127 – (Topic 7)
An administrator is unable to upgrade a vCenter Server Appliance from version 5.1 Update 2 to version 6.0.
What is a likely reason for this?
vCenter Server Appliance 6.0 does not support upgrades from version 5.1 Update 2.
vCenter Server Appliance must be joined to an Active Directory domain before upgrading to version 6.0.
vCenter Server Appliance 5.1 Update 2 uses an incompatible database for upgrading to version 6.0.
vCenter Server Appliance 6.0 must be upgraded using the vSphere Web Client.

Question No: 128 – (Topic 7)
An administrator is troubleshooting a CPU issue for a virtual machine. The following is seen in esxtop:
->CPU0 is at 100% usage
->The remaining logical CPUs are close to 0%
->%RDY value is consistently above 10%
What is likely the cause of the CPU issue?
The virtual machine has a CPU limit configured.
The virtual machine’s guest operating system is configured for SMP.
The virtual machine has CPU affinity configured.
The virtual machine is configured with a CPU reservation.
Answer: C Explanation:
By setting a CPU affinity on the virtual machine you are limiting the available CPUs on which the virtual machine can run. It does not dedicate that CPU to that virtual machine and therefore does not restrict the CPU scheduler from using that CPU for other virtual machines.
Question No: 129 – (Topic 7)
An administrator is observing slow performance of the vCenter Inventory Service and observes the entries from the wrapper.log file:
Exception in thread “tomcat-exec-2” java.lang.OutOfMemoryError: Java heap spaceException in thread “http-bio-0.0.0.0-10443-Acceptor-0” java.lang.OutOfMemoryError: Java heap space
What should the administrator do to resolve the problem?
Increase the memory resources of the vCenter Server.
Increase the values using cloudvm-ram-size.
Increase the memory resouces of the Platform Services Controller.
Increase the wrapper.java.maxmemory value in wrapper.conf.

Question No: 130 – (Topic 7)
Attempting to update an ESXi 6.x host using the following command: esxcli software vib update -d update.zip
Generates the following error:
Could not download from depot at /tmp/index.xml, skipping ((‘/tmp/index.xml’, ”, “[Errno 4] IOError: lt;urlopen error [Error 2] No such file or directory: ‘/tmp/index.xml’gt;”)) url =
What action should be taken to correct the problem?
Add the full file path to the command.
Use the update option instead of install.
Use the switch -d instead of -v.
Replace esxcli with esxupdate.
Answer: A Explanation:
You have to add full file path to the command instead of mentioning the file name only.
