      The question on the link you posted is not exactly the same question :
      “pages that are considered least valuable” VS “pages that are redundant”

  1. Micide says:

    Answer is B.
    It is requested to reclaim “least valuable” memory pages, that’s exactly what the ballooning will do.

    Transparent page sharing is made to track redundant memory pages.

  2. Gary says:

    Yes there is a difference here. Least valuable and redundant copies. If claiming least valuable pages then it’s balloon driver.

    The memory balloon driver (vmmemctl) collaborates with the server to reclaim pages that are considered “least valuable” by the guest operating system.

    Host uses a proprietary transparent page sharing technique to securely eliminate “redundant copies” of memory pages
