Setting the number of ports to the maximum on a vSwitch will exhaust the total ports on a host.

    B is not possible since you can’t share same uplink to different vSwitch, but you can have multiple uplink connected to same vSwitch. So B is not correct.

    About option D:

    The answer can be found under maximum configurations documentation:
    http://www.vmware.com/pdf/vsphere5/r51/vsphere-51-configuration-maximums.pdf on page 2:

    Total virtual network switch ports per host (VDS and VSS ports) = 4096
    Virtual network switch creation ports per standard switch = 4088

    If I base on those two lines i understand option D is incorrect as there will be 4096 – 4088 = 8 ports available for the host.

    What do you think?

    Correct Answers: A C.

    A is correct – Beaconing requires at least 3 uplink ports to perform correctly.
    C is correct – A vSwitch needs to be connected to at least one physical uplink port – you cannot create a vSwitch without assigning an uplink port for it to use.

    B is incorrect as you cannot share uplink ports between different vSwitches.
    D is incorrect as the default number of ports assign to a vSwitch is 128. The number of vSwitch ports has nothing to do with the number of physical ports you have on your host..
