An organization that provides a SaaS solution recently experienced an incident involving customer data loss. The system has a level of self-healing that includes monitoring performance and available resources. When the system detects an issue, the self-healing process is supposed to restart parts of the software.
During the incident, when the self-healing system attempted to restart the services, available disk space on the data drive to restart all the services was inadequate. The self-healing system did not detect that some services did not fully restart and declared the system as fully operational.
Which of the following BEST describes the reason why the silent failure occurred?

  1. The system logs rotated prematurely.
  2. The disk utilization alarms are higher than what the service restarts require.
  3. The number of nodes in the self-healing cluster was healthy.
  4. Conditional checks prior to the service restart succeeded.

A security compliance requirement states that specific environments that handle sensitive data must be protected by need-to-know restrictions and can only connect to authorized endpoints.

  1. NAC to control authorized endpoints
  2. FIM on the servers storing the data
  3. A jump box in the screened subnet
