      B and C is correct.

      Questions is asking for “which two tasks must be completed to comply with upgrade requirements” which is the Prerequisites.

      * Verify that vSAN 6.6 supports the software and hardware components

      * Verify that you are using the latest version of vSAN

      * Verify that you have enough space available to complete the software version upgrade.

      * Verify that you have enough capacity available to upgrade the disk format.

      * Verify that you have placed the vSAN hosts in maintenance mode and selected the Ensure data accessibility or Evacuate all data option.

      * Verify that you have backed up your virtual machines.

    The vSAN cluster upgrade proceeds in the following sequence of tasks.

    1)Upgrade the vCenter Server. See the vSphere Upgrade documentation.

    2)Upgrade the ESXi hosts. See Upgrade the ESXi Hosts. For information about migrating and preparing your ESXi hosts for upgrade, see the vSphere Upgrade

    3)Upgrade the vSAN disk format. Upgrading the disk format is optional, but for best results, upgrade the objects to use the latest version. The on-disk format exposes your environment to the complete feature set of vSAN. See Upgrade vSAN Disk Format Using RVC.

    Best Answer here is B & C

    Question mentions about “two tasks must be completed to comply with
    upgrade requirements and VMware-recommended best practices? ”

    Under Upgrade requirements :
    https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID-0B331151-7CE4-4D18-9A36-638CEEDEF2CC.html

    Virtual Machines Verify that you have backed up your virtual machines.

    For VMware-recommended best practices:

    https://kb.vmware.com/s/article/2146381?other.KM_Utility.getArticleLanguage=1&r=1&other.KM_Utility.getArticleData=1&other.KM_Utility.getArticle=1&ui-comm-runtime-components-aura-components-siteforce-qb.Quarterback.validateRoute=1&other.KM_Utility.getGUser=1

    The vSphere environment is up to date.

    Option A – Could not be correct one as RVC is used to upgrade the vSAN disk format. But here in options it says “Use RVC to upgrade the hosts”

    https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID-874F305A-E794-43EC-AC6C-51EA3DCBBBD0.html

    Option D is not Correct .

    B: Yes, “This first task to perform during the vSAN upgrade is a general vSphere upgrade, which includes upgrading vCenter Server and ESXi hosts.”
    https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID-ABABC0DF-2519-4C8F-A5B1-2AECF86247AB.html

    C: Yes, “Verify that you have backed up your virtual machines.”
    https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID-0B331151-7CE4-4D18-9A36-638CEEDEF2CC.html

    D: No, there is no document about vSAN upgrade where they talk about “Full data migration”

    Answers are B & C

    A: While you would use RVC to upgrade the disk format.
    “The disk format upgrade is optional.”
    B: Upgrade the ESXi Hosts is a step
    “Verify that you are using the latest version of ESXi.”
    C: Of course this is obvious
    “Verify that you have backed up the virtual machines.”
    D: This one is wrong
    “Verify that your hosts are not in maintenance mode. When upgrading the on-
    disk format, do not place your hosts in maintenance mode. When any member
    host of a vSAN cluster enters maintenance mode, the available resource
    capacity in the cluster is reduced because the member host no longer
    contributes capacity to the cluster. The cluster upgrade might fail.”
