• Question 101:

  An ESXi host has be

  en placed into Quarantine Mode by Proactive HA.

  What will happen?

  A. Virtual machines will be migrated off the quarantines host if doing so will not violate any DRS affinity and anti-affinity rules or cause increased resource contention.
  B. Newly powered-on virtual machines may be placed on the quarantined host to balance cluster resources. Already powered-on virtual machines will be migrated off of the quarantined host if doing so will not violate any DRS affinity and anti- affinity rules or cause resource contention.
  C. All virtual machines will be migrated off the quarantined host to other hosts in the cluster without regard to DRS rules.
  D. vSphere HA will conduct a failover on all VMs residing on the quarantined host.
  A. Virtual machines will be migrated off the quarantines host if doing so will not violate any DRS affinity and anti-affinity rules or cause increased resource contention.

  Proactive HA - Proactive HA integrates with select hardware partners to detect degraded components and evacuate VMs from affected hosts before an incident can cause an interruption of service. vCenter Server plug-ins from the hardware vendors provide the health status of hosts' system memory, local storage, power supplies, cooling fans, and network adapters. If components become degraded, Proactive HA determines which hosts are at risk and places them into a new-to

  6.5 state called "Quarantine Mode".

  While in Quarantine Mode, VMs are migrated off of the host onto healthy hosts (as long as affinity and anti- affinity rules are not violated, and the performance of the VM will not be negatively affected). New VMs will not be added to hosts that

  are in Quarantine Mode.

• Question 102:

  In a vSphere 6.5 cluster, the administrator notices that it is possible to set a percentage in the DRS option, "Control CPU over-commitment in the cluster." Which is the purpose of this setting?

  A. It sets and enforces a maximum percentage of virtual machine CPU usage in GHz in comparison to physical CPU availability in GHz.
  B. It sets and enforces a maximum ratio in percentage between powered on virtual machine CPUs and available physical CPUs on hosts.
  C. It prevents the creation of any additional virtual machines in the cluster.
  D. It calculates the total shares assigned to all virtual machines in comparison to GHz of available physical CPU.
  B. It sets and enforces a maximum ratio in percentage between powered on virtual machine CPUs and available physical CPUs on hosts.

• Question 103:

  A Telco customer is implementing NFV using vSphere as the virtualization platform. Which feature can help achieve a high packet rate with lower CPU consumption?

  A. SplitRX
  B. Network I/O Control
  C. ERSPAN
  D. LACP
  A. SplitRX

  SplitRx Mode SplitRx mode uses multiple physical CPUs to process network packets received in a single network queue. This feature can significantly improve network performance for certain workloads. These workloads include: Multiple virtual machines on one ESXi host all receiving multicast traffic from the same source. (SplitRx mode will typically improve throughput and CPU efficiency for these workloads.) Traffic via the vNetwork Appliance (DVFilter) API between two virtual machines on the same ESXi host. (SplitRx mode will typically improve throughput and maximum packet rates for these workloads.) In vSphere 5.1 and later this feature is automatically enabled for a VMXNET3 virtual network adapter (The only adapter type on which it is supported) when ESXi detects that a single network queue on a physical NIC is both (a) heavily utilized and (b) getting more that 10,000 broadcast/multicast packets per second.

• Question 104:

  What are three parameters for traffic filtering or marking? (Choose three.)

  A. Protocol
  B. DSCP value
  C. Traffic Direction
  D. virtual Port ID
  A. Protocol
  B. DSCP value
  C. Traffic Direction

• Question 105:

  A new virtual machine cannot reach its default gateway.

  - The vSphere administrator checks that the virtual machine's vmnic is connected to the correct portgroup, and that the portgroup is on the correct virtual switch

  -This is the only virtual machine on this portgroup

  - Other virtual machines that are on the host and connected to the same Distributed switch are running as normal

  -

  The Distributed Switch has only one uplink Which could be the cause of this issue?

  A. Block All Ports has been selected on the Distributed Switch.
  B. The wrong VLAN ID has been added to the portgroup.
  C. The VLAN has not been configured in virtual machine hardware settings.
  D. The physical adapter is down.
  B. The wrong VLAN ID has been added to the portgroup.

  ---

  The default gateway is an entry point and an exit point in a virtual machine sub-net, VLAN, or network.

  In general, a gateway is a routing device that knows how to pass traffic between different subnets and networks.

  Layer 2 and layer 3 switches with VLAN configuration allow IP assignment to each VLAN that will be used as default gateway as for that particular VLAN. A router contains routes for other subnets. Therefore, the problem occurs when wrong VLAN ID is added to the portgroup.

• Question 106:

  Which is true when assigning global permissions in a single vSphere Single Sign-On domain in a multi-site configuration?

  A. Users assigned global permissions will be able to access objects and solutions across all Single Sign-On domains in an organization.
  B. Users assigned global permissions will be able to access objects and solutions only in the same Single Sign-On site.
  C. Users assigned global permissions will have administrator access across all objects and solutions in a Single Sign-On domain.
  D. Users assigned global permissions will be able to access objects and solutions within that Single Sign-On domain.
  D. Users assigned global permissions will be able to access objects and solutions within that Single Sign-On domain.

  ---

  Global permissions are applied to a global root object that spans solutions, for example, both vCenter Server and vCenter Orchestrator. Use global permissions to give a user or group privileges for all objects in all object hierarchies. Each solution has a root object in its own object hierarchy. The global root object acts as a parent object to each solution object. You can assign global permissions to users or groups, and decide on the role for each user or group. The role determines the set of privileges. You can assign a predefined role or create custom roles.

• Question 107:

  Which three operations can cause VMFS metadata updates? (Choose three.)

  A. Restarting a VM using the guest OS.
  B. Launching a VM console.
  C. Migrating a VM with vMotion.
  D. Powering a VM on or off.
  E. Expanding a VMFS datastore.
  C. Migrating a VM with vMotion.
  D. Powering a VM on or off.
  E. Expanding a VMFS datastore.

  ---

  Metadata is updated each time you perform datastore or virtual machine management operations. Examples of operations requiring metadata updates include the following: Creating, growing, or locking a virtual machine file Changing a file's attributes Powering a virtual machine on or off Creating or deleting a VMFS datastore Expanding a VMFS datastore Creating a template Deploying a virtual machine from a template Migrating a virtual machine with vMotion Reference: https://pubs.vmware.com/vsphere-50/index.jsp?topic=%2Fcom.vmware.vsphere.storage.doc_50%2FGUID-7A385576-9434-432E-92C4- 51E26A4761AA.html

  B. faster Storage vMotion
  C. faster virtual disk provisioning

• Question 109:

  An administrator is trying to add a new virtual disk of 3TB to a virtual machine on a recently upgraded ESXi 6.x host, but receives this error: The disk capacity entered was not a properly formed number or was out of range. It has been replaced with the nearest acceptable value. How can the new virtual disk be added to the virtual machine?

  A. Upgrade the VMFS datastore.
  B. Change the VMFS datastore block size to 8MB.
