An administrator is updating a program running on a virtual machine. The update file has been downloaded as an .iso file and placed on a shared NFS datastore. An attempt to mount the .iso file to the virtual machine fails,but subsequent testing shows that the .iso file can be mounted to a virtual machine running on another ESXi 5.x host.
Which step can be taken to enable access to the .iso file for the affected virtual machine?
Reboot all ESXi hosts in the cluster where the affected virtual machine is running.
Refresh all datastores on the ESXi host running the affected VM.
Rescan all datastores on the ESXi host running the affected VM.
Unmount the volume from the ESXi host running the affected VM, and then addas a new datastore.
Answer: B Explanation:
The first step is to refresh all datastores on the ESXi host running the affected Virtual Machine. This way, the .iso file can be get access from the affected VM. Refreshing datastores, reinitiate the connections and make sure they are working fine.

During peak operating hours, an administrator finds that a business-critical application running in a virtual machine is not performing as well as during normal hours.
Which memory management methodcan be used to guarantee that the application performs well at all times?
Set a reservation equal to the average memory utilization of the virtual machine running the application.
Set the share level to high for the virtual machine running the application and set the share level for all other virtual machines to low.
Check the Reserve all guest memory checkbox.
Set a reservation equal to the installed memory of the ESXi host running the application.

A database administrator has reported periodic poor performance on a particular virtual machine. The virtual machine administrator has noticed a significant drop in performance when utilized memory exceeds 1GB.
What does this indicate and what could be checked next?
The application problems are definitely due to a non-memory-related problem. CPU affinity settings should be checked for this virtual machine.
The application problems are definitely due to a non-memory-related problem. CPU utilization should be checked next, using Windows Task Manager.
The virtual machine might not have physical memory available. Compression and swap activity on the ESXi host should be checked next.
The virtual machine might not have physical memory available. Ensure the memory limit on the VM is set to 0 MB.
Answer: C Explanation:
If theperformance degrades when the memory exceeds the allocated value, the virtual machine might not have physical memory available. Check compression and swap activity on ESXi host to see where the additional memory is going.

What arepossible valid uses for the default No Access role in vCenter? (Choose two.)
Restrict usage on a object for a member of a group assigned full permissions to the object
Restrict access to sensitive VMs for helpdesk staff
Restrict ESX Admins from managing specific hosts directly
Restrict administrators from managing hosts via vCenter

Memory Balloon Driver
Transparent Page Sharing
Redundant Memory Driver

Click the Exhibit button.
Which statement is true about the network performance of the virtual machine in the exhibit?
The virtual machine can send at the maximum of 10Mbps.
The virtual machine can send traffic as fast as the underlying virtual switch allows.
Virtual switch autonegotiation settings must to be adjusted to improve performance.
The underlying physical NIC is configured for 10Mbps.
The virtual machine sends traffic as fast as the underlying virtual switch allows.

An administrator is deploying several ESXi 5.x hosts. Centralized logging with accurate timestamps is a requirement for the deployment. Which two operationsensure these requirements are met? (Choose two.)
Ensure TCP port 123 is not blocked
Configure a syslog server on each host
Configure ensure the hosts have the proper timezone configured
Configure a syslog server on the vSphere Management Appliance
Answer: A,D Explanation:
For centralized logging with accurate timestamps, you need to make sure TCP port 123 is not blocked. You also need to configure a syslog server on the VSA.

An administrator attempts to increase the numberof vCPUs in a virtual machine to 8. The configuration cannot be successfully completed.
What are two likely causes of this issue? (Choose two.)
MS-DOS was selected as guest OS.
The host has 4 processor threads.
Virtual machine hardware version7 was chosen.
The vSphere 5.x implementation is using a Standard license.
Answer: A,B Explanation:
The reasons that can cause the configuration of vCPUs in a VM to not get successfully completed can be several. First, if you have selected MS DOS as aguest OS, then it would not support 8 vCPUs. Check the processor threads. If it has 4 ot less than 4 threads, you cannot increase the number of vCPUs in a VM.
Question No: 170 – (Topic 4)
An administrator is creating a virtual machine that will be running Windows 2008 Enterprise (64-bit). The application to be installed in the virtual machine requires eight vCPUs to run effectively. During installation, the only available options are one, two, three, or four vCPUs.
What condition explains the available vCPU selections?
The virtual machine hardware version is 8.
The guest operating system for the virtual machine is 64-bit.
The ESXi host has two non hyperthreaded dual-core CPUs.
The ESXi host has two hyperthreaded dual-core CPUs.
