An administrator wants to adjust how often the platform checks for security drift without modifying...

The wording “security drift” points to SCMA rather than AIDE. In Nutanix security hardening guidance, SCMA scheduling is the control that determines how often SCMA runs, with schedule options such as hourly, daily, weekly, and monthly. That makes the SCMA schedule the setting that changes the cadence of security drift checking without changing the underlying controls themselves. ( Nutanix Portal )

AIDE is a file-integrity mechanism and has its own role, but the question is specifically asking about how often the platform checks for drift in a broader security-configuration sense. Changing the list of entities inspected or baseline enforcement behavior would alter scope or enforcement semantics, not merely frequency. The most direct administrative answer is to change the schedule for SCMA. From an exam perspective, Nutanix often separates what runs, how it is enforced, and when it runs into different settings. Here the requirement is only about “how often,” so option B is the precise match. ( Nutanix Portal )
