Explanation
A filter block with only one condition configured which states: artifact.*.cef .sourceAddress !- , would permit only non-null IP addresses to pass forward to the next block. The !- operator means "is not null". The other options are not valid because they either include null values or other fields than sourceAddress. See Filter block for more details.

Explanation
The correct answer is C because the Administration > System Health > Playbook Run History page allows viewing the debug log for any playbook execution by selecting the playbook execution entry and then selecting Log. The debug log contains information such as the start and end time, the status, the input parameters, the output results, and any errors or exceptions for each block in the playbook. The answer A is incorrect because the Investigation page does not have a Debug Log option in the playbook's action menu in the Recent Activity panel. The answer B is incorrect because the Expand Scope option in the debug window does not show the debug log for a playbook execution, but the details of the current container and its artifacts.
The answer D is incorrect because the Visual Playbook Editor does not have a Debug Logs option in Settings, but a Debug Mode option that allows testing the playbook with sample data. Reference: Splunk SOAR User Guide, page 100.

Explanation
The correct answer is C because the number of full time employees (FTEs) is one of the settings that can be configured in the Return on Investment (ROI) Settings page. This setting is used to calculate the ROI metrics based on the number of analysts in the organization. The answer A is incorrect because the analyst hours per month is not a configurable setting, but a calculated metric based on the FTEs and the average hours per month. The answer B is incorrect because the time lost is not a configurable setting, but a calculated metric based on the number of incidents and the average time lost per incident. The answer D is incorrect because the annual analyst salary is not a configurable setting, but a calculated metric based on the FTEs and the average salary per analyst.
