A request has been made to the SAN administrator to provision a new LUN. A LUN (LUN 6) is created, and the SAN administrator presents the LUN to an ESXi 5.x host, using the storage array SAN management software. The administrator looks at the Storage configuration for the ESXi host, and does not see the new LUN. Other LUNs from the same storage array are visible.
Which two conditions are most likely to cause the error described? (Choose two.)
A. The administrator has not performed a Rescan All on the ESXi host.
B. The multipathing policy has been set to Fixed for the LUN.
C. Zoning on the Fibre Channel switches is not configured correctly.
D. The LUN was not presented to the correct ESXi host.
The cause of the error is that the administrator didn’t perform a rescan all of ESXi host. Whenever a new LUN is provisioned, a manual rescan all has to be performed to enable ESXi to discover new LUNs. The second possibility is that the new LUN was not presented to the ESXi host that was intended by the administrator.
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?
A. The application problems are definitely due to a non-memory-related problem. CPU affinity settings
should be checked for this virtual machine.
B. The application problems are definitely due to a non-memory-related problem. CPU utilization should
be checked next, using Windows Task Manager.
C. The virtual machine might not have physical memory available. Compression and swap activity on the
ESXi host should be checked next.
D. The virtual machine might not have physical memory available. Ensure the memory limit on the VM is
set to 0 MB.
If the performance 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 would be a valid reason to enable traffic shaping?
A. Limiting the bandwidth of a FTP server
B. Restricting the load on a IDS server
C. Limiting the bandwidth used by an independent hardware iSCSI adapter
D. Improving the performance of a CPU-intensive application server
By limiting the bandwidth of a FTP server, you can enable traffic shaping.
Click the Exhibit button. Assuming that this is the only virtual machine and the only resource pool, what is the maximum amount of memory that can be configured for use by the virtual machine that is part of the finance resource pool?
A. 16,384 MB, less virtual machine overhead
B. 57 MB less virtual machine overhead
C. 3,009 MB, less virtual machine overhead
D. 1 3,375 MB, less virtual machine overhead
Users have reported performance issues with an application running on a Windows VM. Performance analysis shows high CPU activity on the ESXi host but low CPU activity on the Windows VM.
A high value in which overview graph and counter on the virtual machine’s Performance tab would confirm the results of the performance analysis?
A. CPU (%) / Wait
B. CPU Usage (Mhz) / Wait
C. CPU Usage (Mhz) / Ready
D. CPU (%) / Ready
The value in CPU (%)/Ready graph on the virtual machine performance tab would confirm the results of the performance analysis.
Which option could be used for vSphere HA heartbeats?
A. An iSCSI LUN used for booting the master ESXi host.
B. An iSCSI LUN backing an RDM connected over 10GB Ethernet
C. An NFS datastore shared with the all hosts, sync, no_root_squash and read only options
D. A Fibre Channel LUN on an 8GB active/active array backing a VMFS5 datastore
Fibre Channel LUN on an 8GB active/active array backing up a VMFS5 datastore will work with vSphere HA heartbeats.
An administrator has deployed a vSphere 5 implementation. Due to security reasons the system state of a virtual machine must be reverted on a regular basis what feature will meet this requirement?
A. Create the virtual machine using Independent-Persistent disks
B. Create a Scheduled Task using the Delete All Snapshots option according to security requirements
C. Create the virtual machine using Independent-Nonpersistent disks
D. Create a Scheduled Task using the Delete Snapshot option to delete the most recent snapshot according
to security requirements.
An administrator is using Update Manager 5.0 to update virtual appliances in a vSphere environment. The environment is using the vCenter Server appliance. The administrator is unable to remediate the vCenter Server appliance.
What would cause the remediation to fail?
A. Updating of the appliance can only be done if the vCenter Server Appliance has been
B. Remediation must be configured on the Appliance Administration page before use
C. Remediation of the vCenter Server Appliance with Update Manager is not supported
D. Remediation of the vCenter Server Appliance must be done from the PowerCLL
What is the size of a virtual machine .vswp file if defaults are accepted for the virtual machine reservations, limits, and shares?
A. The virtual machine. vswp file is equal to twice the amount of available memory configured for the
virtual machine when it was created.
B. The virtual machine. vswp file is equal to the amount of virtual memory (virtual machine available
memory, plus virtual machine overhead the virtual machine when it was created.
C. The virtual machine. vswp file is equal to zero length when the virtual machine is created and expands
D. The virtual machine. vswp file is equal to the amount of available memory configured for the virtual
machine when it was created.
An administrator receives a call indicating users reported extremely slow access to virtual machines the previous evening. Access to virtual machines performs as expected as checked by the administrator. Over the course of several days, the administrator continues to receive calls about the issue, which appears to occur at intermittent times each evening.
Which step can be taken to collect information about the issue?
A. Create a condition alarm to alert when Datastore Disk Usage (*) exceeds 70%
B. Collect esxtop performance data in batch mode and analyze total number of I/O operations (CMDS/s)
C. Create an event alarm to alert when a storage device is disconnected
D. Collect esxtop performance data in batch mode and analyze average device latency (DAVG/cm-d)
