20+ practice questions focused on Database and Application Forensics — one of the most tested topics on the Computer Hacking Forensic Investigator CHFI exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Database and Application Forensics PracticeDuring a database forensic investigation, an analyst discovers that multiple rows in a MySQL table have been deleted. The binary logs are enabled. Which approach should the analyst use to recover the deleted data?
Explanation: MySQL binary logs record all changes to the database, including DELETE statements. The mysqlbinlog utility can parse these logs to reconstruct the exact DELETE operations, allowing the analyst to reverse-engineer the deleted rows by extracting the row data from the log events. This is the standard forensic method for recovering deleted data when binary logging is enabled.
A forensic analyst is investigating a compromised web application that uses an Oracle database. The analyst suspects that SQL injection was used to extract sensitive data. Which Oracle log source would provide evidence of the injected SQL statements?
Explanation: The listener.log is the correct source because Oracle's listener records all client connections and SQL*Net traffic, including the raw SQL statements sent to the database. When SQL injection is performed, the injected payload is transmitted as part of the SQL query over the network, and the listener log captures these exact statements, providing direct evidence of the attack.
A forensic analyst is examining a PostgreSQL database server that was compromised. The attacker gained superuser access and deleted several rows from a critical table. The database is configured with WAL (Write-Ahead Log) archiving. Which method would allow the analyst to identify the exact time the deletions occurred?
Explanation: D is correct because `pg_waldump` is the PostgreSQL utility specifically designed to parse Write-Ahead Log (WAL) files and display their contents in a human-readable format, including the exact timestamps and operation types (e.g., DELETE). Since the database uses WAL archiving, the archived WAL segments will contain a record of every data modification, allowing the analyst to pinpoint when the deletions occurred.
Which TWO of the following are valid methods for collecting volatile data from a live database server during an incident response?
Explanation: `netstat -an` lists all active network connections and listening ports without performing DNS resolution, which is critical for identifying unauthorized connections or ongoing data exfiltration from the live database server. This command retrieves data from the kernel's network stack, which is volatile and would be lost if the system were powered down.
Which THREE of the following are essential steps in the forensic analysis of a compromised web application that uses a MySQL backend?
Explanation: Stored procedures, triggers, and user-defined functions (UDFs) in MySQL can be maliciously created or modified by an attacker to execute arbitrary code, escalate privileges, or maintain persistence. Forensic analysis must inspect these objects for unauthorized changes, as they are often overlooked but can contain backdoor logic that survives database restarts and backups.

Practice all Database and Application Forensics questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Database and Application Forensics. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Database and Application Forensics questions on the CHFI frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Database and Application Forensics is tested as part of the Computer Hacking Forensic Investigator CHFI blueprint. Practicing with targeted Database and Application Forensics questions ensures you can handle any format or difficulty that appears.
