Recovery Site Strategies for the technology environment depend on how much downtime an organization can tolerate before the recovery must be completed.
What would you call a strategy where the alternate site is internal, standby ready, with all the technology and equipment necessary to run the applications?

Internal Hot SiteThis site is standby ready with all the technology and equipment necessary to run the applications positioned there.
The planner will be able to effectively restart an application in a hot site recovery without having to perform any bare metal recovery of servers.
If this is an internal solution, then often the organization will run non-time sensitive processes there such as development or test environments, which will be pushed aside for recovery of production when needed.
When employing this strategy, it is important that the two environments be kept as close to identical as possible to avoid problems with O/S levels, hardware differences, capacity differences, etc., from preventing or delaying recovery.
Recovery Site Strategies Depending on how much downtime an organization has before the technology recovery must be complete, recovery strategies selected for the technology environment could be any one of the following: Dual Data CenterThis strategy is employed for applications, which cannot accept any downtime without negatively impacting the organization.
The applications are split between two geographically dispersed data centers and either load balanced between the two centers or hot swapped between the two centers.
The surviving data center must have enough head room to carry the full production load in either case.
External Hot SiteThis strategy has equipment on the floor waiting, but the environment must be rebuilt for the recovery.
These are services contracted through a recovery service provider.
Again, it is important that the two environments be kept as close to identical as possible to avoid problems with O/S levels, hardware differences, capacity differences, etc., from preventing or delaying recovery.
Hot site vendors tend to have the most commonly used hardware and software products to attract the largest number of customers to utilize the site.
Unique equipment or software would generally need to be provided by the organization either at time of disaster or stored there ahead of time.
Warm SiteA leased or rented facility that is usually partially configured with some equipment, but not the actual computers.
It will generally have all the cooling, cabling, and networks in place to accommodate the recovery but the actual servers, mainframe, etc., equipment are delivered to the site at time of disaster.
Cold SiteA cold site is a shell or empty data center space with no technology on the floor.
All technology must be purchased or acquired at the time of disaster.

The correct answer to the question is C. Internal Hot Site.
An Internal Hot Site is a disaster recovery strategy that involves having a standby site within the organization's own facilities, equipped with all the necessary technology and equipment required to run critical applications in the event of a disaster. In an Internal Hot Site, the alternate site is typically located within the same building or campus as the primary site, or in a nearby facility that is easily accessible to the organization.
The term "hot site" indicates that the alternate site is fully operational and ready to take over in the event of a disaster, without any delay or interruption in the services provided to customers or users. The equipment and systems at the hot site are kept in a state of readiness, with regular maintenance and testing to ensure that they are fully functional and can be brought online quickly if needed.
An Internal Hot Site provides the highest level of protection and the fastest recovery time in the event of a disaster. Since the site is located within the organization's own facilities, it is easily accessible and provides complete control over the recovery process. This strategy is most appropriate for organizations that require high availability and minimal downtime, and can afford the cost of maintaining a duplicate infrastructure.
In contrast, an External Hot Site is a disaster recovery strategy that involves having a standby site located off-site, usually in a different geographic location, which is fully equipped with the necessary technology and equipment to run critical applications in the event of a disaster. A Warm Site is a disaster recovery strategy that involves having a site equipped with some of the necessary technology and equipment, but not all, which requires some setup and configuration before it can be fully operational. A Dual Data Center is a disaster recovery strategy that involves having two fully operational data centers located in different geographic locations, which are synchronized to ensure that data is always available in the event of a disaster.
