Questions and Answers
  • 1. 

    Which two Identity Sources are available to add for vCenter Single Sign-On authentication?(Choose two.)

    • A.

      LocalOS

    • B.

      OpenLDAP

    • C.

      NIS as an LDAP Server

    • D.

      VCMSDS

    Correct Answer(s)
    A. LocalOS
    B. OpenLDAP
    Explanation
    The correct answer is LocalOS and OpenLDAP. LocalOS refers to the local operating system, which means that users can authenticate using the credentials of the operating system where vCenter is installed. OpenLDAP is an open-source implementation of the Lightweight Directory Access Protocol (LDAP) and can be used as an identity source for authentication in vCenter. NIS as an LDAP Server and VCMSDS are not valid identity sources for vCenter Single Sign-On authentication.

    An administrator is configuring the Failover Order option on a vSphere Distributed Switch.Which two options should be used with IP-hash load balancing? (Choose two.)

    • A.

      Active Uplinks

    • B.

      Standby Uplinks

    • C.

      Unused Uplinks

    • D.

      Override Failover Order

    Correct Answer(s)
    A. Active Uplinks
    C. Unused Uplinks
    Explanation
    When using IP-hash load balancing on a vSphere Distributed Switch, the administrator should use the "Active Uplinks" option. This ensures that all active uplinks are utilized for load balancing. Additionally, the "Unused Uplinks" option should also be used to include any uplinks that are not currently being used. This allows for efficient load distribution across all available uplinks in the network. The "Standby Uplinks" option is not used with IP-hash load balancing, as it is only used for failover purposes. The "Override Failover Order" option is also not relevant in this scenario.

    Correct Answer(s)
    B. A datastore planned for the solution is configured as a Raw Device Mapping file.
    C. A datastore planned for the solution has three extents.
    E. The organization has an Enterprise license.
    Explanation
    The three conditions that would prevent Storage I/O Control from being enabled on a group of datastores are:
    1. A datastore planned for the solution is configured as a Raw Device Mapping file. Raw Device Mapping files do not support Storage I/O Control.
    2. A datastore planned for the solution has three extents. Storage I/O Control does not support datastores with multiple extents.
    3. The organization has an Enterprise license. Storage I/O Control is only available with Enterprise Plus licenses.

    A virtual machine is experiencing performance issues. The following performance metricsare observed:✑ CPU usage value for the virtual machine is above 90%✑ CPU ready value for the virtual machine is above 20%Which two activities will likely resolve the performance issues? (Choose two.)

    • A.

      Set a CPU reservation for the virtual machine.

    • B.

      Increase the CPU limit on the virtual machine.

    • C.

      Decrease CPU shares equally for all virtual machines on the host.

    • D.

      Increase CPU shares equally for all virtual machines on the host.

    Correct Answer(s)
    A. Set a CPU reservation for the virtual machine.
    B. Increase the CPU limit on the virtual machine.
    Explanation
    Setting a CPU reservation for the virtual machine ensures that a certain amount of CPU resources are always available for it, which can help improve its performance. Increasing the CPU limit on the virtual machine allows it to use more CPU resources when needed, which can also help resolve the performance issues. Both of these activities aim to allocate more CPU resources to the virtual machine, thereby addressing the high CPU usage and CPU ready values observed.

  • 5. 

    What is true regarding datastores on ESXi 6.x?

    • A.

      NFS 4.1 datastore does not support Fault Tolerance (FT)

    • B.

      VMFS3 and VMFS5 datastores can be newly created

    • C.

      NFS datastore can be concurrently mounted using NFS 4.1 on one host and NFS on another

    • D.

      NFS 3.0 datastore does not support Fault Tolerance (FT)

    Correct Answer
    A. NFS 4.1 datastore does not support Fault Tolerance (FT)
    Explanation
    NFS 4.1 datastore does not support Fault Tolerance (FT). This means that if an ESXi host using NFS 4.1 datastore fails, Fault Tolerance cannot be used to automatically switch to a secondary host without any downtime. FT is a feature that provides continuous availability for virtual machines by creating a secondary copy of the VM that runs on a different host. However, NFS 4.1 does not support this feature, so FT cannot be used with NFS 4.1 datastores.

  • 6. 

    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.

    Correct Answer(s)
    A. Remote Storage has been disconnected.
    B. Installation media is available.
    C. Server hardware clock is set to UTC.
    Explanation
    The three items that should be validated prior to installing ESXi 6.x are: Remote Storage has been disconnected, Installation media is available, and Server hardware clock is set to UTC. These validations ensure that the installation process can proceed smoothly. Disconnecting remote storage helps prevent any potential data loss during the installation. Having the installation media available is necessary to initiate the installation process. Setting the server hardware clock to UTC ensures that time synchronization will work correctly after the installation.
