Click on the arrows to vote for the correct answer
A. B. C. D.B.
A hot site has the equipment, software and communications capabilities to facilitate a recovery within a few minutes or hours following the notification of a disaster to the organization's primary site.
With the exception of providing your own hot site, commercial hot sites provide the greatest protection.
Most will allow you up to six weeks to restore your sites if you declare a disaster.
They also permit an annual amount of time to test the Disaster Plan.
The following answers are incorrect: Cold sites.Cold sites are empty computer rooms consisting only of environmental systems, such as air conditioning and raised floors, etc.
They do not meet the requirements of most regulators and boards of directors that the disaster plan be tested at least annually.
Reciprocal Agreement.Reciprocal agreements are not contracts and cannot be enforced.
You cannot force someone you have such an agreement with to provide processing to you.
Government regulators do not accept reciprocal agreements as valid disaster recovery backup sites.
Time Brokers.
Time Brokers promise to deliver processing time on other systems.
They charge a fee, but cannot guaranty that processing will always be available, especially in areas that experienced multiple disasters.

The most effective backup site for disaster recovery depends on the specific needs and resources of an organization. Here's an explanation of each option:
A. Time brokers: Time brokers are not a type of backup site. Time brokers are a service that helps organizations find and reserve resources such as computing power or network bandwidth on a temporary basis. This can be useful for organizations that need additional resources during a disaster recovery event, but time brokers alone cannot provide a backup site.
B. Hot sites: Hot sites are fully equipped backup sites that are ready to take over operations in the event of a disaster. They usually have all the necessary hardware, software, and data to continue business operations, and they can be activated quickly. Hot sites are the most effective backup site for disaster recovery because they provide near-immediate recovery of business operations.
C. Cold sites: Cold sites are backup sites that have the necessary infrastructure to restore operations but lack the necessary hardware, software, and data. In the event of a disaster, the organization would need to bring its own equipment and restore its data to the cold site. Cold sites can take longer to activate than hot sites, but they can be less expensive and are still a viable option for disaster recovery.
D. Reciprocal Agreement: A reciprocal agreement is not a type of backup site. A reciprocal agreement is an agreement between two organizations to provide backup support to each other in the event of a disaster. This can involve sharing resources or providing access to backup sites. Reciprocal agreements can be an effective way to ensure disaster recovery, but they do not provide a backup site on their own.
In conclusion, hot sites are generally the most effective backup site for disaster recovery, as they are fully equipped and ready to take over operations quickly. However, cold sites and reciprocal agreements can also be effective backup options depending on an organization's specific needs and resources.
