Which of the following is widely used as an exploit database/resource for security testing?

• A. The Wall Street Transcript
• B. EDGAR Database
• C. Metasploit
• D. LexisNexis

Answer: (C)

The main idea is recognizing a tool that serves as a comprehensive exploit resource used in security testing. Metasploit is a widely used framework that houses a large collection of exploit modules, payloads, and auxiliary tools, letting testers simulate real-world attacks in a controlled environment to validate vulnerabilities and assess defenses. The other options are not exploit databases: The Wall Street Transcript is a financial news publication, the EDGAR Database stores SEC filings for corporate research, and LexisNexis is a legal and public-records research service. Metasploit’s extensive module library and testing workflow make it the go-to resource for exploit testing.
