The correct answer is C.
OBJ-2.2: If the cybersecurity analyst were to reduce the scans’ sensitivity, it still would not decrease the time spent scanning the network and could alter the effectiveness of the results received. In this scenario, the scans, as currently scoped, are taking more than 24 hours to complete with the current resources. The analyst could reduce the scans’ scope, thereby scanning fewer systems or vulnerabilities signatures and taking less time to complete. Alternatively, the analyst could reduce the scans’ frequency by moving to a less frequent schedule, such as one scan every 48 hours or one scan per week. The final option would be to add additional vulnerability scanners to the process. This would allow the two scanners to work together to divide the workload and complete the task within the 24-hour scan frequency currently provided.
