Which type of backup subscription service will allow a business to
recover quickest?

A.
A mobile or rolling backup service

B.
A warm site

C.
A cold site

D.
A hot site

Explanation:
The correct answer is “A hot sit”. Warm and cold sites require more work
after the event occurs to get them to full operating functionality. A
mobile backup site might be useful for specific types of minor outages,
but a hot site is still the main choice of backup processing site.
