CompTIA CASP+ (CAS-003) — Question 245

A network service on a production system keeps crashing at random times. The systems administrator suspects a bug in the listener is causing the service to crash, resulting in a DoS. When the service crashes, a core dump is left in the /tmp directory. Which of the following tools can the systems administrator use to reproduce these symptoms?

Answer options

• A. Fuzzer
• B. Vulnerability scanner
• C. Core dump analyzer
• D. Debugger

Correct answer: A

Explanation

The correct answer is A, as a fuzzer is designed to input random data into a program to identify bugs, which can help reproduce the symptoms of the crashing service. Options B and C do not focus on reproducing bugs in real-time, while D, although useful for debugging, does not inherently replicate the conditions leading to the crashes.
