  B. The incorrect Operating System was selected in the virtual machine options.

  C. The software prerequisites have not been installed.

  D. The prerequisite services have not been started.

  Correct Answer: AB

  Among the probable causes, one might be that the VMware tools installation media is corrupt or the

  incorrect OS was selected in the virtual machine options.

• Question 62:

  A Fault Tolerance (FT) virtual machine with four vCPUs is experiencing high latency when performing ICMP and Application tests.

  What are three potential causes that may be attributing to this latency? (Choose three.)

  A. The FT network has insufficient bandwidth and is running on a 1GB Link.

  B. The FT network is on a particularly high latency link.

  C. The FT network has been configured with Network I/O Control.

  D. The FT virtual machine is running an e1000 network adapter.

  E. The FT virtual machine is running on poor performing network-based storage.

  Correct Answer: ABC

  The latency can be caused by FT network having insufficient bandwidth and is running on a 1 GB link or the network is on a particularly high latency risk. The other reason might be that the FT network has been configured with network I/O control.

• Question 63:

  An administrator has unsuccessfully attempted several times to install an Operating System inside a virtual machine. The administrator finds that the installation fails at random intervals.

  Which two actions can be taken to resolve this issue? (Choose two.)

  A. Verify the md5sum and if invalid, download the installation files again.

  B. Attempt the installation an additional time.

  C. Attempt to use a different installation media or installation method.

  D. Create a new virtual machine and attempt the installation with the existing media.

  Correct Answer: AC

  First verify md5sum and if it is invalid, download installation files again. Secondly, attempt to use a different installation media because the one used might be corrupt.

• Question 64:

  Refer to the Exhibit.

  

  A 4 GB Memory virtual machine is experiencing extended memory issues, as shown in the Exhibit. What potential issues could be attributed to this memory pressure?

  A. A limit is imposed on the virtual memory of this virtual machine.

  B. The Balloon driver has been uninstalled.

  C. A limit has been imposed on the Virtual CPU of the virtual machine.

  D. Storage IO control has been enabled for the virtual machine causing the swapped memory.

  Correct Answer: AB

  One of the issue might be that the limit is imposed on the virtual memory of this VM. Secondly, the balloon driver has been uninstalled. That's why it is experiencing memory issues.

• Question 65:

  An administrator is attempting to power on a virtual machine, but is unable to do so.

  Which two reasons are probable causes of the failure? (Choose two.)

  A. Storage access to the virtual machine swap file has been lost.

  B. One of the virtual machine VMDK files is locked.

  C. Virtual machine is running CentOS 7.0 64-bit.

  D. Virtual machine has Hyper-Threading enabled.

  Correct Answer: AB

  One of the reasons it is doing so is because the storage access to the VM machine swap file has been lost

  or one of the VMDK files is locked.

• Question 66:

  Why are some virtual machines orphaned after rebooting a High Availability (HA) enabled host?

  A. The Orphaned virtual machines have HA restart disabled.

  B. The Orphaned virtual machines moved recently and the change did not persist.

  C. The host is attached to failed storage.

  D. The host just came out of maintenance mode.

  Correct Answer: A

  If the host is rebooted within an hour after the virtual machines are moved or powered on, the vmInventory.xml file does not persist and hostd does not report these virtual machines as registered on the host. In an HA-enabled cluster, this condition impacts only the virtual machines with HA restart disabled. Reference: https://kb.vmware.com/selfservice/microsites/search.do?

• Question 67:

  An administrator is troubleshooting basic network connectivity issues.

  Which two scenarios are potential issues that this administrator might face? (Choose two.)

  A. The vSwitch is not attached to the correct physical network.

  B. The portgroup is not configured to use correct VLAN.

  C. Traffic shaping is configured incorrectly.

  D. Jumbo frames is configured incorrectly.

  Correct Answer: AB

  Common network connectivity issues can happen anytime during the operation. The vSwitch is not attached to the correct physical network or the portgroup is not configured to use correct VLAN might be some of the causes that admin has to face during network connectivity.

• Question 68:

  What may be a cause for failure to unmount an NFS datastore?

  A. It has active snapshot files.

  B. It is being used for High Availability (HA) heartbeat.

  C. It is part of a Cluster.

  D. It is managed by Distributed Resource Scheduler (DRS).

  Correct Answer: B

  vSphere HA heartbeating does not prevent you from unmounting the datastore. If a datastore is used for heartbeating, unmounting it might cause the host to fail and restart any active virtual machine. If the heartbeating check fails, the vSphere Client displays a warning.

• Question 69:

  What are two possible causes of Storage Distributed Resource Scheduler (SDRS) being disabled on one or more virtual machine disks in a datastore cluster? (Choose two.)

  A. The virtual machine has vSphere Fault Tolerance disabled.

  B. The virtual machine is a template.

  C. The virtual machine swap file is on a shared datastore.

  D. The disk is a CD-ROM/ISO file.

  Correct Answer: BD

  Possible causes of SDRS being disabled might be related to the fact that the virtual machine is a template or the disk is a CD-ROM or an ISO file.

• Question 70:

  Which scenario shows a reason for VMware Tools failing to install?

  A. Virtual machine has a CD-ROM configured.

  B. Guest OS Antivirus is blocking the VMware Tools installation.

  C. Guest OS has 64-bit ldd (list dynamic dependencies) utility installed.

  D. Virtual machine is powered on.

  Correct Answer: B

  One of the reasons for VMware tools to fail during installation is that the Guest OS antivirus is blocking the installation thinking it is a malware.
