ECS enforces multiple policy rules to ensure compliance with SEC 17a-4(f) regulations. Which two policy rules are valid after enabling compliance? (Select 2)

The correct answer is B. Retained objects cannot be erased until their retention period expires. C. Retention periods for stored objects can be increased but not decreased. SEC 17a-4(f) is an SEC regulation mandating that electronic records be stored in a non-rewriteable, non-erasable (WORM) format for a defined retention period. Options B and C directly reflect these core WORM requirements: objects are immutable until their retention period…

Explanation

SEC 17a-4(f) is an SEC regulation mandating that electronic records be stored in a non-rewriteable, non-erasable (WORM) format for a defined retention period. Options B and C directly reflect these core WORM requirements: objects are immutable until their retention period expires (B), and while retention periods can be extended to ensure longer preservation, they can never be shortened - preventing circumvention of regulatory minimums (C).

A is wrong because a compliant bucket containing objects still under retention cannot be deleted; doing so would violate the non-erasable mandate of 17a-4(f). The bucket is locked as long as retained objects exist within it.

D is wrong because ECS software-only solutions do not support policy-based compliance under SEC 17a-4(f) - only the ECS Appliance (hardware) solution provides the necessary certified immutability guarantees required by the regulation.

Memory tip: Think WORM + Extend-Only. Like a worm that only moves forward - retention time can only go forward (increase), never backward (decrease), and nothing gets deleted until the clock runs out.
