    what is the meaning of this question and what's the possible best
    answer:
    ============================
    Q- Why is router on a stick a necessary solution?

    1-because Layer 2 LAN switches can also operate at Layer 3
    2-because routers cannot route packets between multiple VLANs
    3-because Layer 2 LAN switches can only support a single VLAN
    4-because Layer 2 LAN switches cannot switch frames between multiple
    VLANs

    google this group for "router on a stick"

    That's obviously wrong so you can eliminate that.

    > 2-because routers cannot route packets between multiple VLANs


    That's true on some routers but not all routers.

    > 3-because Layer 2 LAN switches can only support a single VLAN


    That's true on some layer 2 switches but not all layer 2 switches.

    > 4-because Layer 2 LAN switches cannot switch frames between multiple

    There are some unusual switches and unusual definitions of VLANs;
    that one would probably be good for some beer arguments with some
    old timers.

    What is the basic function that a router performs ?

    With the answer for that question you can divine the answer to your
    posted question

    Looks like one of the questions in the CCNA intro book.
