Which command helps an incident handler retrieve active transaction log files for a database?

The Database Consistency Checker (DBCC) is specifically designed to assess the integrity and consistency of a database in SQL Server environments. When dealing with incidents that may involve compromised databases, an incident handler can utilize DBCC commands not only to check the health of the database but also to retrieve metadata about transaction logs and active transactions.

This utility can help identify issues within the database, ensure that all transactions are accounted for, and validate the structure of the database, which is essential during the incident response process. By using DBCC commands, an incident handler can gather crucial information about the state of the database and its transaction logs, assisting in recovery and forensic analysis.

In contrast, the other options, such as Uname, PsInfo, and Executed Console, serve different purposes. Uname provides information about the user and the system, PsInfo is a tool for retrieving information about processes running on a system, and Executed Console may pertain to commands executed in a specific context but does not directly deal with database logs. Thus, these options do not fulfill the requirement of retrieving active transaction log files like the Database Consistency Checker does.
