A company wants to ensure their website, which allows customers to purchase products, is in a cluster at another geographical location. Which of the following solutions does this represent?

Differential backups are a type of backup strategy for data recovery, not for providing an immediately available website at another geographical location.

Data deduplication is a process of eliminating redundant data copies to reduce storage, which does not provide geographical redundancy or high availability for a website.

A cold site is a disaster recovery solution where a secondary, geographically separate location is prepared with basic infrastructure but typically lacks live data and active hardware, meant for recovery over a longer period after a disaster.

High availability (HA) is a general concept aiming for continuous uptime, often within a single location or closely linked regions, whereas a cold site specifically describes a disaster recovery solution involving a separate physical location.
