Click the Exhibit button.
Based on the exhibit, what is the reason that two of the paths are marked asstandby?
The other two paths were set to active.
That is a characteristic of the storage array used.
The active paths were set to preferred.
The storage adapters need to be rescanned before those paths will be set to active.
Answer: B Explanation:
These paths are in standby mode because this is the characteristic of the storage array in use.

Users are experiencing performance issues when updating their database hosted on a virtual machine. Theadministrator determines that disk I/O is high across one of the HBAs on the ESXi host containing the virtual machine.
What is the action will most likely correct the issue without significantly impacting other users or datastores?
Manually configurethe disk multipathing policy to Round Robin for the datastore
Migrate the virtual machine to an NFS datastore using Storage vMotion
Use Storage vMotion to migrate the virtual machine to a new VMFS5 datastore
Map additional LUNs to the ESXi host and extend the datastores

ACME Catering Services is using esxtop to troubleshoot a performance problem with one of their ESXi 5.x hosts. Host disconnections from vCenter Server as well as sluggish performance when performing tasks on the host have been observed. Based on the output in the exhibit, how many vCPU#39;s have been assigned to FileServer01?
Answer: D Explanation:
As we can see at the top we have 14vCPUs, 7VMs. So we have 14 vCPUs todistribute between the 7 VMs. I’ve broken down my thought process into several steps after looking for hints:
->Hint 1. Fileserver01 has a huge %RDY value (113.49). This means
overprovisioning of vCPUs, excessive usage of vSMP or a limit (check %MLMTD) has been set.
->Hint 2. %MLMTD is 0.00. That means that the VM is not throttled. %MLMTD
definition: the percentage of time the vCPU was ready to run but deliberately wasn’t scheduled because that would violate the “CPU limit” settings. If larger than 0 the worldis being throttled due to the limit on CPU.
->Hint 3. Check %CSTP. It is 9.28, when the others are zero. %CSTP definition:
Excessive usage of vSMP. Decrease amount of vCPUs for this particular VM. This should lead to increased scheduling opportunities.
Now, seeing how high RDY is we definately get a hint that FileSever01 is overprovisioned. Add a value of 9.28 of %CSTP to the equation and that is definitely the case. In fact, with such a huge %CSTP I would guess that it is overprovisioned 8:1, meaning thatit probably has a 8vcpus.
Both scenarios 1 and 2 have a total of 14 vCPUs. However, due to the fact of %CSTP of being 9.28 I’d probably go with scenario 01 and say 8 vCPUs instead of 4vCPUs.

Which of these factors indicates a high likelihood that the performance of a virtual machine disk is being constrained by disk I/O?
A large number of commands issued
A high device latency value
A high disk used value
A large number of kilobytes read and written
Answer: B Explanation:
Diskperformance bottlenecks are usually due to either Disk queue length or Disk Latency

It appears that a single vCPU virtual machine in a resource pool called Production is having performance problems because it does not have enough CPU resources available.
Which two methods can be used to improve performance and reduce CPU contention of this virtual machine while maintaining compatibility with DRS? (Choose two.)
Configure a CPU reservation for this virtual machine.
Increase the CPU shares for the resource pool.
Increase the CPU shares for the virtual machine.
Increase the share priority setting for the Production resource pool.
Answer: A,C Explanation:
To improve performance and reduce CPU contention of this virtual machine, you need to configure a CPU reservation and increase CPU shares for this virtual machine.

Virtual machine VM1 is unable to communicate with virtual machine VM2. Both virtual machines are connected to a portgroup named Production on vSwitch1on host ESXi01.
Which statement could explain why?
The only vmnic connected to vSwitch1 on ESXi01 is set to unused
The only vmnic connected to vSwitch1 on ESXi01 is set to standby
Load balancing settings on Production do not match vSwitch1
VM1 is configured for VGT, VM2 is configured for VST

An administrator is creating a new virtual machine using the New Virtual Machine wizard in custom mode on an ESXi 5.x host with two quad-core CPUs. What would limit the maximum number of virtual sockets for the virtual machine to8? (Choose three.)
Windows 2008 32-bit is configured as the guest operating system.
Virtual machine hardware version 8 is configured for the VM.
Hyperthreading is disabled on the ESXi host.
The ESXi host is configured with a Standard license.
The number of cores per virtual socket is set to 4.
Answer: C,D,E Explanation:
Disable hyperthreading on the ESXi host and configure the host with a standard license. Then set the number of cores per virtual socket to 4 and you will limit the virtual sockets for a virtual machine to 8.

What are two valid Resource settings that can be set at the vApp level? (Chose two.)
Answer: B,C Explanation:
CPU and Memory can be set at the vApp level. Reference:http://pubs.vmware.com/vsphere- 51/index.jsp?topic=/com.vmware.powercli.cmdletref.doc/Set-VApp.html
Question No: 150 – (Topic 4)
An administrator creates a new Role of quot;Virtual Machine Creatorquot; for members of the helpdesk and server teams. Privileges include.
Datastore – Allocate space Network – Assign network
Resource – Assign virtual machine to resource pool Virtual machine gt;Configuration – all
Virtual machine gt; Interaction – all
The new role is granted to the teams at the appropriate VMs and Templates folder, Cluster and Datastore objects.
After applying the role, users report they are unable to create new Virtual Machines. What should be changed to allow new virtual machines to be created?
Add a privilege to the role Virtual machine gt;Inventory – Create new
Grant the teams the role at the Datacenter level
Ensure Propagate to Child Objects is selected on the objects.
Grant the teams the role on the Production network object.
