Restoration after a ransomware attack is typically led by the data administrator because backup and recovery of data are core responsibilities of that role.

1) Relevant knowledge points and concepts
- Roles: Data administrator (or database administrator/DBA) is responsible for data integrity, backup/restore procedures, disaster recovery planning and execution. Database programmers develop application code but don’t typically manage recovery operations. Database security officers focus on policy, access control and prevention, not hands‑on restoration. Systems analysts design system requirements and processes but do not usually lead operational restores. 
- Backup concepts: full, differential, and incremental backups; restore sequences; Recovery Time Objective (RTO) and Recovery Point Objective (RPO); integrity verification and consistency checks.
- Incident response: isolation, assessment, recovery, validation, and post-incident hardening.

2) Step-by-step reasoning process
- Immediately after the attack, the team must identify affected databases and isolate compromised systems to prevent spread.
- The team leader must locate the most recent valid backups (understanding whether full, differential, incremental are needed), determine applicable restore sequence, and coordinate hardware/VM provisioning.
- The data administrator directs the restore order (e.g., system catalog first, then user databases), executes restores, applies transaction logs if needed, and runs consistency checks.
- They validate data integrity, coordinate application reconnection, reset credentials, and confirm systems meet RTO/RPO goals before returning to production.

3) Intermediate steps (restore sequence example)
- Identify latest full backup (t0).
- Apply subsequent differential backups (if any) or apply incremental backups in chronological order.
- Replay transaction logs up to the desired recovery point.
- Run DBCC/consistency checks and user acceptance tests.

4) Why the correct answer is correct
- The data administrator has the procedures, authority and technical responsibility to restore databases, manage backup sets, and ensure data consistency — exactly what is needed after ransomware destroys database servers.

5) Why other options are incorrect
- Database programmer: writes and maintains code, not responsible for backup/recovery leadership.
- Database security officer: focuses on security policy and investigation, not operational restoration.
- Systems analyst: analyzes and designs systems but does not usually coordinate urgent data restores.

6) Conclusion
The correct leader for restoring data from backups and returning systems to normal operation is the Data administrator, matching the provided answer.

After a ransomware attack destroys several critical database servers, the team responsible for restoring data from backups and returning systems to normal operation would most likely be led by the _____. 单项选择题
