• Question 12:

  An administrator is configuring the Maximum Transmission Unit value on a vSphere Distributed Switch.

  Which two options are typical values for ESXi networking? (Choose two.)

  A. 1492
  B. 1500

  To configure Jumbo Frames on a vDS using vSphere Client on vCenter Server 5.1 and earlier:

  1.

  From vCenter Server click, click Home > Inventory > Networking.

  2.

  Right-click the vDS and click Edit Settings.

  3.

  On the Properties tab, select the Advanced option.

  4.

  Change the Maximum MTU value from the default value of 1500 to 9000. This enables Jumbo Frames on all portgroups and ports. Reference: https://kb.vmware.com/selfservice/microsites/search.do?language=en_USandcmd=displayKCandexternalId=1038827

• Question 13:

  What is a benefit of using Enhanced vMotion Compatibility for an environment?

  A. EVC masks dissimilar CPU features.
  B. EVC allows for cross platform vMotion to occur.
  C. EVC enables Storage vMotion functionality.
  D. EVC enables Long Distance vMotion.
  A. EVC masks dissimilar CPU features.

• Question 14:

  Which three traffic types are available services options when configuring a vmkernel port? (Choose three.)

  A. Provisioning Traffic
  B. Virtual Volumes Traffic
  C. vSphere Replication NFC Traffic
  D. Virtual SAN Traffic
  E. FCoE Traffic
  A. Provisioning Traffic
  C. vSphere Replication NFC Traffic
  D. Virtual SAN Traffic

  ---

  You can enable services for the default TCP/IP stack on the host. Select from the available services:

  vMotion traffic. Enables the VMkernel adapter to advertise itself to another host as the network connection where vMotion traffic is sent. The migration with vMotion to the selected host is not possible if the vMotion service is not enabled for

  any VMkernel adapter on the default TCP/IP stack, or if no adapters are using the vMotion TCP/IP stack.

  Provisioning traffic. Handles the data transferred for virtual machine cold migration, cloning, and snapshot creation.

  Fault Tolerance traffic. Enables Fault Tolerance logging on the host. You can use only one VMkernel adapter for FT traffic per host.

  Management traffic. Enables the management traffic for the host and vCenter Server. Typically, hosts have such a VMkernel adapter created when the ESXi software was installed. You can create another VMkernel adapter for management

  traffic on the host to provide redundancy.

  vSphere Replication traffic.Handles the outgoing replication data that is sent from the sourceESXi host to the vSphere Replication server.

  vSphere Replication NFC traffic. Handles the incoming replication data on the target replication site.

  Virtual SAN. Enables the Virtual SAN traffic on the host. Every host that is part from a Virtual SAN cluster must have such a VMkernel adapter.

• Question 15:

  A virtual machine template is accidently removed from the vCenter Server Inventory. Which method would be used to recover the template back into the environment?

  A. Use the datastore browser to locate the template, then right click and add the .vmtx file to inventory.
  B. Use the datastore browser to locate the template, then right click and add the .vmx file to inventory.
  C. Using the Managed Object Browser and adding the template from the ManagedObjectReference:GuestFileManager object.
  D. Using the Managed Object Browser and adding the template from the ManagedObjectReference:VirtualDiskManager object.
  A. Use the datastore browser to locate the template, then right click and add the .vmtx file to inventory.

  ---

  Templates are associated with hosts, and the only way to regain or register templates after removing and adding a host is to use the datastore browser to locate the template. Then use the inventory wizard to name and register the .vmtx file as a template back into vCenter Server.

• Question 16:

  Refer to the Exhibit.

  

  A storage administrator is not seeing full utilization of all bandwidth from an ESXi host. The vSphere administrator observes the adapter details, as shown in the Exhibit.

  What is the probable cause of this issue?

  A. Another path needs to be used to allow full utilization of the bandwidth.
  B. The array is not setup to use the correct multipathing policy.
  C. There are no virtual machines on the host.
  D. No traffic is being sent across it because a path failed.
  D. No traffic is being sent across it because a path failed.

  ---

  It seems that no traffic is being sent across it due to the path that has failed.

• Question 17:

  Which two storage controller configurations can be used with Virtual SAN? (Choose two.)

  A. SAS controllers in Passthrough mode
  B. SAS controllers in RAID0 mode
  C. SAS controllers in RAID1 mode
  D. SAS controllers in RAID10 mode
  A. SAS controllers in Passthrough mode
  B. SAS controllers in RAID0 mode

  ---

  SAS controllers in passthrough mode and in RAID 0 mode can be used with virtual SAN.

• Question 18:

  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.
  A. The hosts in the cluster are disconnected.
  B. A host in the cluster is displaying an HA error.

  ---

  One of the causes is that the hosts in the cluster are disconnected. They might be displaying an HA error.

• Question 19:

  An administrator is creating a new Virtual SAN cluster on a Layer 2 network. There is an existing Virtual SAN cluster on the same Layer 2 network. Which two actions would allow the new Virtual SAN cluster to coexist with the previously created cluster? (Choose two.)

  A. Change the default Multicast Address on the new Virtual SAN cluster.
  B. Change the default Unicast Address on the new Virtual SAN Cluster.
  C. Create a separate VLAN for each cluster.
  D. Create an ARP Alias for the Virtual SAN VMkernel Network Adapter.
  A. Change the default Multicast Address on the new Virtual SAN cluster.
  B. Change the default Unicast Address on the new Virtual SAN Cluster.

  ---

  To configure virtual san cluster to coexist with older cluster, you need to change the default multicast address on the netw virtual san cluster and change the default unicast address on the new virtual san cluster.

• Question 20:

  Which three items should be validated prior to installing ESXi 6.x? (Choose three.)

  A. Remote Storage has been disconnected.
  B. Installation media is available.
  C. Server hardware clock is set to UTC.
  D. Storage has been partitioned with a VMFS volume.
  E. Network cards have been setup to use Jumbo Frames.
  A. Remote Storage has been disconnected.
  B. Installation media is available.
  C. Server hardware clock is set to UTC.

  ---

  Validate remote storage is disconnected. Install media is available and server hardware clock is set to UTC.
