Exam SK0-005 topic 1 question 209 discussion

A. A cold site - does not typically have data until the cold site becomes activated. ***B. Data at rest. - the scenario states "Hosting data in different regional locations". Hosted data is AVAILABLE for use, even if it is not moved or accessed for long periods of time. By contrast, stored data is typically archival, or part of a retention requirement. C. on-site retention - data retention strategies are typically stored data, not hosted data. D. off-site storage - the scenario states "Hosting data", not "storing data".

Data at Rest refers to data that is in a storage. It could be a Hard Disk Drive or an SSD. I can be accessed all the time, or never. Where it is stored really doesn't matter. It could be on your home PC, a server, a remote location or anywhere else. The answer is D because the data is being stored at a remote location which is what the question is asking "different regional location".

The term that describes hosting data in different regional locations but not moving it for long periods of time is "data at rest". Data at rest refers to data that is not actively being used or transmitted, but is instead stored in a particular location or on a particular device. This can include data that is stored on hard drives, flash drives, or other storage media, as well as data that is stored in the cloud or on remote servers. Option A, a cold site, refers to a backup facility that is not operational until a disaster occurs and is typically used for disaster recovery purposes. Option C, on-site retention, refers to the practice of storing data on site, typically for regulatory or compliance purposes. Option D, off-site storage, refers to the practice of storing data in a location other than the primary data center, typically for backup or disaster recovery purposes.
