An administrator tries to run esxtop to troubleshoot CPU performance issues, but no output is displayed.
How can the issue be resolved?
esxtop is deprecated in vSphere 6.x, resxtop must be used to produce the desired output.
In esxtop, press f and place an asterisk next to each field that should be displayed.
sudo should be run in front of esxtop to give the administrator the proper permissions.
The esxtop command must be run from the /proc directory to produce output.
When you press f and place an asterisk next to each field that you want displayed, esxtop will definitely display performance issues, if any.
Question No: 133 – (Topic 7)
An administrator is attempting to enable Legacy Fault Tolerance (FT) on a virtual machine and observes the following in the vSphere Web Client:
Fault Tolerance has not been licensed on host lt;hostnamegt;.
What is the minimum licensed edition that supports this configuration?
Answer: A Explanation:
Fault Tolerance is not licensed in all editions of VMware vSphere. Check the edition you are running and upgrade to an edition that includes Fault Tolerance.
Question No: 134 – (Topic 7)
Which two reasons would prevent Storage Distributed Resource Scheduler (SDRS) from operating on a datastore? (Choose two.)
The datastore has Storage I/O Control disabled.
The datastore is connected to an unsupported host.
The datastore is hosted on an NFS server.
The datastore is hosted on an iSCSI server.
Question No: 135 – (Topic 7)
When a Content Library is deleted, what happens to the files contained on the backing storage?
The files will be unchanged.
The files will be deleted.
The files will remain and be marked as orphaned.
The containing folder will be marked as orphaned.
Answer: B Explanation:
When the content library is deleted, the files in backup storage will also be deleted.
Question No: 136 – (Topic 7)
An administrator is upgrading an ESXi 5.5 host to ESXi 6.x and gets the following error: MEMORY_SIZE
What does this indicate?
Insufficient memory on the ESXi host to complete the upgrade.
Insufficient memory for Auto Deploy to complete the upgrade.
Insufficient memory in vCenter Server to complete the upgrade.
Insufficient memory for Update Manager to complete the upgrade.
When you install less than 4GB of memory, Memory_Size error occurs because ESXi host requires at least 4 GB of memory.
Question No: 137 – (Topic 7)
An administrator is troubleshooting a CPU performance issue for a virtual machine. Which three esxtop counters may demonstrate CPU contention? (Choose three.)
Question No: 138 – (Topic 7)
What are two reasons why a local flash device would be unavailable for use with Virtual SAN? (Choose two.)
It has a VMFS datastore present.
It is in use by the vFlash Read Cache feature.
It is smaller than the minimum capacity required for Virtual SAN usage.
It does not have any partitions created.

Question No: 139 – (Topic 7)
Refer to the Exhibit.
An administrator is troubleshooting intermittent poor performance of virtual machines in a vSphere 6.x cluster. Investigating esxtop data shows that the only statistic that stands out is %CSTP as depicted in Exhibit 1:
The administrator proceeds to switch to the Power Management screen and observes the data depicted in Exhibit 2:
Based on the information in the exhibits, which two configurations are probable causes of the poor performance? (Choose two.)
The active power policy is set to Low Power.
The host has active Sleep States configured in the BIOS.
The active power policy is set to High Performance.
The host has active Power States configured in the BIOS.
Answer: A,B Explanation:
It seems that the active power policy has a low power setting and the host has active sleep states configured in the BIOS.
Question No: 140 – (Topic 7)
Refer to the Exhibit.
An administrator is troubleshooting a CPU performance related problem for the SlowVM
Which three actions should the administrator take to improve CPU performance for SlowVM? (Choose three.)
Increase the number of vCPUs assigned to SlowVM.
Decrease the number of vCPUs assigned to SlowVM.
Power off other VMs running on the same ESXi host.
Increase the CPU limit for SlowVM.
Move SlowVM to another ESXi host with more physical CPU resources available.
Answer: B,C,E Explanation:
SlowVM can have increased CPU performance if the number of vCPUs are decreased. Trim down the burden by powering off other VMs running on the same ESXi host or you can move the concerned VM to another ESXi host with more physical CPU resources.
