• Question 143:

  VM1 requires console access to virtual machine VM1, as shown in the Exhibit: A user

  

  Based on the exhibit, what action would provide the minimum level of access needed to meet this requirement?

  A. Grant Virtual machine user access to the Datacenter with Propagation to children enabled.
  B. Modify the permission for user VM1 on the VMs folder to the Virtual machine user role.
  C. Remove the No Access permission for user VM1 from the VMs folder.
  D. Grant Virtual machine user access to the Test VMs folder.
  B. Modify the permission for user VM1 on the VMs folder to the Virtual machine user role.

• Question 144:

  How many Link Aggregation Groups (LAGs) can be configured on a vSphere 6.x Distributed Switch?

  A. 64
  B. 96
  C. 128
  D. 256
  A. 64

  ---

  You can create up to 64 LAGs on a distributed switch. A host can support up to 32 LAGs. However, the number of LAGs that you can actually use depends on the capabilities of the underlying physical environment and the topology of the virtual network. For example, if the physical switch supports up to four ports in an LACP port channel, you can connect up to four physical NICs per host to a LAG.

• Question 145:

  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.
  A. The Orphaned virtual machines have HA restart disabled.

  ---

  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.

• Question 146:

  A vApp template recently added to a Content Library is not displayed. Which two actions could correct this problem? (Choose two.)

  A. Manually synchronize the library
  B. Select the Download all library content immediately option
  C. Select the Sync subscribed library option
  D. Manually download the vApp template
  A. Manually synchronize the library
  B. Select the Download all library content immediately option

  ---

  If the vApp template is not displayed in the content library, select the download all library content immediately option and manually synchronize the library.

• Question 147:

  An administrator is editing the management network configuration of an ESXi 6.x host from the vSphere Web Client, but mistakenly puts the incorrect VLAN in place for the management network. What action do you need to take to correct this?

  A. No action is required. By default, ESXi rolls back configuration changes that disconnect the host.
  B. The ESXi host system configuration will need to be restored to the factory configuration to fix the issue.
  C. Manually edit the configuration on the host with command line utilities.
  D. The change can be reverted in the vSphere Web Client by simply editing the switch again.
  A. No action is required. By default, ESXi rolls back configuration changes that disconnect the host.

• Question 148:

  Refer to the Exhibit.

  

  An administrator logs into the vSphere Web Client and sees the warning shown in the Exhibit. During a change control window, the warning was addressed.

  What should be done to verify that the host is no longer showing the warning?

  A. Run a Remediate host operation.
  B. Recheck the compliance of the host.
  C. Restart the host to get rid of the warning.
  D. Install VMware tools to clear the warning.
  B. Recheck the compliance of the host.

  ---

  To make sure the host is no longer showing the warning, recheck the compliance of the host.

• Question 149:

  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.
  A. A limit is imposed on the virtual memory of this virtual machine.
  B. The Balloon driver has been uninstalled.

  ---

  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 150:

  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.
  A. Storage access to the virtual machine swap file has been lost.
  B. One of the virtual machine VMDK files is locked.

  ---

  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. Reference: https://kb.vmware.com/selfservice/microsites/search.do?language=en_USandcmd=displayKCandexternalId=10051
