The scheme above is somewhat unconventional. It is more common for programs and data to be moved only between adjacent levels of the hierarchy.Give several arguments against allowing transfers directly from the cache to any level other than primary memory.

What will be an ideal response?

The hardware would be simpler, because there would be fewer communications
paths to manage. More importantly, transfers from the cache to secondary or
tertiary memory would be so slow as to invalidate the advantage of having the
cache.
