An administrator is using the Host Failures to Tolerate Admission Control Policy for a vSphere High Availability (HA) cluster. When configuring this setting on the cluster, the administrator sees this error message: Insufficient resources to satisfy HA failover level on cluster What are two likely causes for the error? (Choose two.)

A.The hosts in the cluster are disconnected. B.A host in the cluster is displaying an HA error. C.Distributed Resource Scheduler has not been configured on the cluster. D.Virtual Machine Component Protection has not been turned on. Answer: A,B Explanation: One of the causes is that the hosts in the cluster are disconnected. They might be …

An administrator is installing a new network card in an ESXi 6.x host that is part of a vSphere cluster. When the host is placed into maintenance mode, the vSphere Web Client displays the progress bar at 2% for over 30 minutes. Which two are likely reasons for this occurrence? (Choose two.)

A.Maintenance mode is unable to migrate all virtual machines from the host. B.There is a large number of virtual machines that must be migrated from the host. C.VMware High Availability is in the process of reconfiguring the cluster. D.Each virtual machine on the ESXi host must be reconfigured to recognize the new adapter. Answer: A,B …

An administrator is monitoring a High Availability (HA) and Distributed Resource Scheduler (DRS) enabled cluster and has noticed that virtual machines in the cluster are being migrated without user intervention. Why is this happening?

A.The DRS Automation level is set to Fully Automated. B.The Automation level is set to Automatic. C.The DPM Threshold is set to Aggressive. D.The Power Management feature is configured. Answer: A Explanation: When the DRS automation level is set to filly automated, virtual machines in the cluster might be migrated without user intervention.

When attempting to power on a Virtual Machine you observe the following error: Cannot open the disk ‘/vmfs/volumes/volume/vm/vm-000002.vmdk’ or one of the snapshot disks it depends on. Which three actions will be the best solutions to address this problem? (Choose three.)

A.Verify that the virtual machine’s diskfiles are present. B.Investigate the host and virtual machine log files. C.Verify the vmdk descriptor files and if required, recreate them. D.Delete the disk file preventing the power on operation. E.Migrate or register the virtual machine to adifferent host. Answer: A,B,C Explanation: First verify that the VM disk files are …

A physical Windows 2008 R2 Server is converted to a virtual machine using VMware vCenter Converter. Upon completion of the conversion and subsequent power on operation, the virtual machine fails to boot and the message below is observed in the Console of the virtual machine: STOP 0x0000007B INACCESSIBLE_BOOT_DEVICE Which two potential issues may be causing this boot failure? (Choose two.)

A.An incorrect SCSI controller was selected during conversion. B.Incompatible software drivers were migrated into the virtual machine from the source machine. C.The vmdk file backing the virtual machine was thick provisioned. D.A snapshot was taken immediately after the conversioncompleted. Answer: A,B Explanation: It might be the incorrect SCSI controller was selected during conversion or the …

When attempting to access a virtual machine, an administrator is unable to login using the vSphere credentials. What two options are probable causes of the authentication failure? (Choose two.)

A.The vSphere credentials have not been granted permissions. B.The vSphere credentials are granted read-only permissions. C.The vSphere credentials are granted no-access permissions. D.The vSphere credentials are not a member of the local administrator group. Answer: A,B Explanation: While the details of authentication and authorization differ between ESX/ESXi and vCenter Server, the model itself is the …

A user is trying to retrieve objects from a SharePoint server and finds the request is taking an excessive amount of time. An administrator tries to isolate the issue and notes the following: Application performance is poor when compared to virtual machines on other hosts. Performance improves when the virtual machine is moved to another host. Thevirtual machine encounters higher than expected CPU %Ready times. What conclusion can be reached regarding the performance issues for this virtual machine?

A.Host Power Management is directly impacting virtual machine performance. B.The virtual machine has a large number of snapshots. C.The Path Selection Policy for the storage device is set differently on the affected host D. Network I/O control is configured for the portgroup. Answer: A Explanation: Processor Power Management (Power Saving, PowerScaling) is impacting application performance …
