Question 64

Data mirroring is an important strategy of business continuity planning.

Data mirroring involves creating copies of data in real-time to ensure its availability in the event of a system failure or disaster. This strategy is crucial for maintaining operational continuity and minimizing data loss.

A) Service variety

Service variety refers to offering a range of services to meet diverse customer needs. While it can enhance business resilience, it is not a specific strategy for business continuity planning, which focuses on maintaining operations during disruptions.

B) Data mirroring

Data mirroring is a proactive strategy that involves duplicating data across multiple locations or systems. This ensures that if one system fails, the data remains accessible from another source, thereby supporting uninterrupted business operations and safeguarding against data loss.

C) Data encryption

Data encryption is essential for protecting sensitive information from unauthorized access. Although it is a critical security measure, it does not directly relate to the continuity of operations during a disaster, making it less relevant as a primary strategy for business continuity planning.

D) User authentication

User authentication is a security measure used to verify the identity of individuals accessing a system. While important for security and access control, it does not address the continuity of business operations in the face of disruptions, thus not qualifying as a key strategy in business continuity planning.

Conclusion

Data mirroring stands out as the correct answer because it directly addresses the need for maintaining data accessibility and operational continuity during unexpected events. Other options, while relevant to security and service diversity, do not fulfill the specific requirements of business continuity planning, which prioritizes data availability and resilience.
