Which of the following is used by storage tiering to meet SLAs?

RBAC is essential for maintaining the integrity and security of storage tiering configurations, directly impacting the ability to meet SLAs. By restricting access to modify tiering policies to authorized roles, RBAC prevents unauthorized changes that could compromise performance, cost efficiency, or data compliance, thereby ensuring tiering operates as intended to fulfill service level agreements.

Rules sets define the logic for how data moves between storage tiers but are not themselves the underlying mechanism for enforcing who can manage these rules or for meeting broader security-related aspects of SLAs.

Policies dictate the specific criteria and actions for storage tiering, such as data movement based on access patterns or age, but RBAC controls who has the authority to define and implement these policies.

Cron jobs are schedulers for executing tasks at specific times, which could trigger tiering processes, but they do not define the logic or provide the authorization framework for tiering to meet SLAs.
