    a) execute SELECT and JOIN before the implementation of binary actions
    b) execute SELECT and UNION before the executing of binary actions
    c) execute SELECT and PROJECT before the executing of binary actions
    d) alternative a and b
    e) none of the above

  2. DBA privileged commands also include:
    a) determining the end user requests
    b) specification development for registered transactions
    c) deletion of some privileges which were given before to some accounts
    d) all of the above
    e) alternative a and c
    f) none of the above

  3. which of the below can/may be the right index:
    a) secondary index
    b) cluster index
    c) primary index
    d) all of the above
    e) alternative b and c
    f) none of the above

Why do you have an exam in a topic you’ve never learned anything about?

This is a forum for people who are interested in learning or helping others learn, not to cheat on tests.

You might have better luck in the paid section (or other coder for hire sites)
