Which of the following describes an effective disaster recovery strategy?

An effective disaster recovery strategy is best exemplified by employing a mix of hot, warm, and cold sites for flexibility. This approach allows an organization to tailor its disaster recovery capabilities based on the specific needs of the business and the criticality of its applications and data.

Hot sites are fully operational facilities that can be used immediately after a disaster, which is ideal for mission-critical systems that require minimal downtime. Warm sites, on the other hand, are partially equipped and require some configuration and data loading to become operational, making them a more cost-effective solution for less critical operations. Cold sites are essentially empty facilities with no active IT equipment but can be brought online as a long-term recovery option. This mixture provides the organization with a range of recovery time objectives (RTOs) and recovery point objectives (RPOs) that can be adjusted according to the situation, helping balance cost and downtime.

Using only hot sites limits flexibility and can lead to unnecessary financial strain, while having no predefined recovery locations significantly compromises recovery planning and can lead to confusion and delays during a disaster. Relying solely on cloud storage solutions may not address all recovery needs, as it may not provide infrastructure or environment for full operational recovery, particularly for organizations with stringent uptime requirements, complex
