Answer:
Those who take a "layer-cake" view of federalism believe that strict, defined lines and boundaries should be established for the powers of both the federal and state governments. The "layer-cake" ideology, also known as dual federalism, establishes that federal and state governments should be separate, but equal, and operate within their own domain, not impeding on one another, such as in Marble Cake, or cooperative federalism, in which powers are skewed occasionally for the sake of cooperation and mutual benefit for state and national goals.
