ある企業は、メインのデータセンターで災害が発生した場合にすぐに使用できる機器を備えたディザスタ リカバリ サイトを必要としています。この会社には、すべてのライブ データをディザスタ リカバリ サイトにミラーリングするための予算がありません。次のコンセプトのうち、会社が選択すべきものはどれですか?
正解:C
A warm site is a type of disaster recovery site that has equipment ready to go in the event of a disaster at the main datacenter, but does not have live data or applications. A warm site requires some time and effort to restore the data and services from backups, but it is less expensive than a hot site that has live data and applications. A cold site is a disaster recovery site that has no equipment or data, and requires a lot of time and money to set up after a disaster. A cloud site is a disaster recovery site that uses cloud computing resources to provide data and services, but it may have issues with bandwidth, latency, security, and cost.
