Certified Data Centre Professional (CDCP) Practice Exam

Implementing security measures against unauthorized access is critical for maintaining data integrity in a data center because it protects the integrity and confidentiality of data from potential breaches and tampering. When unauthorized individuals gain access to a data center, they could manipulate, delete, or corrupt sensitive information which would compromise the reliability of that data.

To uphold data integrity, it's essential to have robust security protocols in place, including firewalls, intrusion detection systems, and access controls that regulate who can access data and under what circumstances. This ensures that only authorized personnel can interact with the data, helping to preserve its accuracy and trustworthiness.

In the context of data integrity, while using multiple software applications, documenting user access, and regularly updating hardware can contribute to overall data center management and security, they do not directly safeguard against unauthorized alterations to the data itself. Therefore, focusing on stringent security measures is the most effective way to ensure that data remains intact and trustworthy.
