For each of the cache modifications that we could perform, select whether it will increase,
decrease, have no effect, or have an unknown effect on the parameter.
• An unknown effect means that it could either decrease or increase the parameter in
question.
• No effect also includes marginal or very little effect
• When answering for multilevel caching, answer based on the caching system as a whole.
