Which maintenance processes should a database administrator prioritize to ensure data integrity in a mission-critical database?

• A. Regular backups
• B. Data corruption checks
• C. User access reviews
• D. Network security assessments

Answer: (B)

Prioritizing data corruption checks is essential for ensuring data integrity in a mission-critical database. This process involves continuously monitoring the database for any signs of corruption, which can occur due to various factors such as hardware failures, software bugs, or unexpected shutdowns. By implementing regular data corruption checks, the database administrator can quickly identify and address any issues before they lead to data loss or integrity violations.

Maintaining data integrity means ensuring that the data stored in the database is accurate, consistent, and reliable. By catching corruption early, the administrator can utilize measures such as repairs or restores to minimize potential damages and maintain the overall health of the database system.

While regular backups, user access reviews, and network security assessments are all important aspects of database administration, they contribute to different facets of database management. Backups are critical for data recovery, access reviews help with security and compliance, and security assessments focus on protecting the database from external threats. However, without integrity checks, even the most secure and well-backed-up databases can suffer from internal data issues that compromise their reliability.
