  B. There is a storage I/O constraint.
  C. There is insufficient disk space assigned to the virtual machine.
  D. The application is not virtualization aware.
  A. There is a network I/O constraint.
  B. There is a storage I/O constraint.

• Question 63:

  An administrator is given a bash script that retrieves data for ESXi 6.x host configurations. This data needs to be collected right after the installation of a host and must be run directly on the host.

  Which two actions can be used to run this script on an ESXi host? (Choose two.)

  A. Connect to the host with Ruby vSphere Console and run the script from there.
  B. Enable SSH access from the Direct Console User Interface.
  C. Enable the ESXi Shell from the Direct Console User Interface.
  D. Run the script directly from the vSphere Web Client.
  B. Enable SSH access from the Direct Console User Interface.
  C. Enable the ESXi Shell from the Direct Console User Interface.

  ---

  The Direct Console User Interface (DCUI) allows you to interact with the host locally using text-based menus. You can use the Direct Console User Interface to enable local and remote access to the ESXi Shell.

• Question 64:

  Which load balancing policy, previously limited to vSphere Distributed Switches, is now available on vSphere Standard Switches with vSphere 6.x?

  A. Route based on physical NIC workload
  B. Route based on IP Hash
  C. Route based on the originating virtual port
  D. Route based on Source MAC Hash
  A. Route based on physical NIC workload

  ---

  Route based on physical NIC workload was limited to vSphere Distributed switches. Now its available on vSphere standard switches with vSphere 6.x

• Question 65:

  What must be enabled to ensure that VM Component Protection (VMCP) works in a High Availability cluster?

  A. VMware Tools Virtual Machine Communication Interface (VMCI)
  B. Fault Tolerance
  C. Atomic Test and Set (ATS)
  D. All Paths Down (APD) Timeout
  D. All Paths Down (APD) Timeout

  ---

  There are two types of datastore accessibility failure:

  PDL (Permanent Device Loss) is an unrecoverable loss of accessibility that occurs when a storage device reports the datastore is no longer accessible by the host. This condition cannot be reverted without powering off virtual machines.

  APD (All Paths Down) represents a transient or unknown accessibility loss or any other unidentified delay in I/O processing. This type of accessibility issue is recoverable.

• Question 66:

  Refer to the Exhibit.

  

  An administrator is migrating a powered-on virtual machine, as shown in the exhibit. Which option should be selected to perform a Storage vMotion of the VM?

  A. Change storage only
  B. Change VM compute resource only
  C. Change both compute resource and storage, changing the compute resource first.
  D. Change both compute resource and storage, changing the storage resource first.
  A. Change storage only

• Question 67:

  During a new vSphere Distributed Switch configuration, where does the Maximum Transmission Unit (MTU) value get modified?

  A. Uplink Settings
  B. Switch Settings
  C. Portgroup Settings
  D. NIC Teaming Settings
  B. Switch Settings

  ---

  You can modify MTU values in switch settings.

• Question 68:

  Which two components can be used when configuring Enhanced Linked Mode? (Choose two.)

  A. vCenter Server Appliance
  B. vRealize Operations Manager
  C. vSphere Management Appliance
  D. vCenter Server for Windows
  A. vCenter Server Appliance
  D. vCenter Server for Windows

  ---

  With Enhanced Linked Mode, you can connect not only vCenter Server systems running on Windows but also many vCenter Server Appliances. You can also have an environment where multiple vCenter Server systems and vCenter Server Appliances are linked together. Reference: https://pubs.vmware.com/vsphere-60/index.jsp?topic=%2Fcom.vmware.vsphere.install.doc%2FGUID-91EF7282-C45A-4E48-ADB0-5A4230A91FF2.html

• Question 69:

  When modifying a vApp, which two vSphere entities can be added? (Choose two.)

  A. A resource pool
  B. A network pool
  C. A vApp
  D. A folder
  A. A resource pool
  B. A network pool

  ---

  A resource pool and a network pool can be added when modifying a vApp.

• Question 70:

  An administrator is tasked with setting up an iSCSI solution on an ESXI 6.x host. To provide multiple paths to the iSCSI array, the administrator chooses to setup iSCSI Port Binding. Which three statements are true in regard to setting up iSCSI Port Binding? (Choose three.)

  A. Port binding works across multiple routers as long as the network mask is the same.
  B. iSCSI target array ports must reside in the same broadcast domain as the VMkernel adapters.
  C. iSCSI VMkernel adapters must be on different virtual switches.
  D. All VMkernel adapters used for iSCSI connectivity must reside in the same virtual switch.
  E. Port binding cannot be used in conjunction with network routing.
  B. iSCSI target array ports must reside in the same broadcast domain as the VMkernel adapters.
  D. All VMkernel adapters used for iSCSI connectivity must reside in the same virtual switch.
  E. Port binding cannot be used in conjunction with network routing.

  ---

  Port binding is used in iSCSI when multiple VMkernel ports for iSCSI reside in the same broadcast domain and IP subnet to allow multiple paths to an iSCSI array that broadcasts a single IP address. When using port binding, you must

  remember that:

  Array Target iSCSI ports must reside in the same broadcast domain and IP subnet as the VMkernel port.

  All VMkernel ports used for iSCSI connectivity must reside in the same broadcast domain and IP subnet.

  All VMkernel ports used for iSCSI connectivity must reside in the same vSwitch.

  Currently, port binding does not support network routing.
