Peach Correct answer- A. Hydra Which of the following situations would cause a penetration tester to communicate with a system owner/client during the course of a test? (Select Two) A. The tester discovers personally identifiable data on the system. B. The system shows evidence of prior unauthorized compromise C. The system shows a lack of hardening throughout D. The system becomes unavailable following an attempted exploit E. The tester discovers a finding on an out-of-scope system Correct answer- B. The system shows evidence of prior unauthorized compromise E. The tester discovers a finding on an out-of-scope system A penetration tester has performed a security assessment for a startup firm. The report lists a total of ten vulnerabilities, with five identified as critical. The client does not have the remediate to immediately remediate all vulnerabilities. Under such circumstances which of the following would be the BEST suggestion for the client? A. Apply easy compensating controls for critical vulnerabilities to minimize the risk, and then reprioritize remediation B. Identify the issues that can be remediated most quickly and address them first. C. Implement the least impactful of the critical vulnerabilities' remediations first, and then address other critical vulnerabilities D. Fix the most critical vulnerability first, even if it means fixing the other vulnerabilities may take a very long time. Correct answer- D. Fix the most critical vulnerability first, even if it means fixing the other vulnerabilities may take a very long time. Which of the following is the reason why a penetration tester would run the chkconfig --del servicename command at the end of an engagement? A. To remove the persistence B. To enable persistence C. To report persistence D. To check for persistence Correct answer- A. To remove the persistence A penetration tester wants to target NETBIOS name service.
