                                  CompTIA Cybersecurity Analyst (CySA+) Certification Exam Sample Questions (Q184-Q189):

                                  NEW QUESTION # 184
                                  A security analyst analyzes the output of a web application access log for a company based in the United States. Given the following output:

                                  Which of the following users should be investigated first?

                                  Answer: D

                                  Explanation:
                                  tlindy has a successful login from a Russian IP address between successful U.S.-based logins, indicating a potentially compromised account or impossible-travel activity. The other Russian login attempts shown were unsuccessful.


                                  NEW QUESTION # 185
                                  A SOC analyst scans a group of servers to search for vulnerabilities. After analyzing the output, the analyst realizes that some OS versions were not detected properly. Which of the following is the best option to increase the accuracy of the scan?

                                  Answer: B

                                  Explanation:
                                  Credentialed scans authenticate to the target systems and can directly query the operating system for detailed configuration and version information. This provides much more accurate results than unauthenticated scanning and helps correctly identify OS versions, installed software, and vulnerabilities.


                                  NEW QUESTION # 186
                                  A security analyst discovers several vulnerabilities on a critical legacy system. The analyst must recommend a solution with the following limitations:
                                  - No downtime is permitted due to criticality.
                                  - Patches for the vulnerabilities do not exist.
                                  - No redundancy systems are in place.
                                  Which of the following is the best risk management strategy to implement?

                                  Answer: A

                                  Explanation:
                                  When vulnerabilities cannot be patched and the system must remain operational, implementing compensating controls reduces the likelihood or impact of exploitation. This approach lowers risk without requiring downtime or system replacement, aligning with mitigation as the appropriate strategy.


                                  NEW QUESTION # 187
                                  A security operations center (SOC) analyst investigates the results of a password spray test conducted by the vulnerability management team.
                                  The analyst must:

                                  Identify Linux systems that have successful and unsuccessful logins with username "User1".
                                  Create an output report named "linux-events" of all the events to a flat file.
                                  The analyst issues the following console command:
                                  ls /var/log/
                                  The shortened output of the command is below:
                                  Which of the following commands should the analyst use to meet the report output requirements?

                                  Answer: B

                                  Explanation:
                                  /var/log/auth.log is the appropriate source because it records authentication and authorization activity on Debian/Ubuntu-style Linux systems, including password-related events, SSH logins, PAM authentication, and other authorization events. Canonical's Ubuntu documentation specifically identifies /var/log/auth.log as the authorization log used for password prompts, sudo, and remote logins.
                                  The command performs three operations. cat /var/log/auth.log sends the log contents to standard output. The pipe forwards that data to grep "User1", which selects records containing the required username. Finally, > linux-events.txt redirects the resulting matching records into the requested flat-file report. Because auth.log can contain both accepted and rejected authentication activity, the command can capture successful and unsuccessful events associated with User1.
                                  sssd is not the general authentication log path shown in the scenario and may contain only SSSD-specific events. A faillog-oriented source emphasizes failed logins and therefore does not satisfy the requirement to collect both successful and failed activity. /var/log/syslog contains broad system messages but is less precise than the dedicated authentication log.

                                  NEW QUESTION # 188
                                  An analyst reviews a summarized vulnerability report through a governance, risk, and compliance (GRC) reporting tool. The following report correlates asset information from the configuration management database (CMDB) against detected vulnerabilities:

                                  Which of the following servers should the analyst prioritize based on the target value, the risk, and the likelihood of exploitation?

                                  Answer: B

                                  Explanation:
                                  PRODWEB-01 is a high-value, publicly exposed asset with a high-severity vulnerability, making exploitation more likely and its potential impact significant. A patch is also available for immediate remediation.
