NS0-157 · Question #141
Identify two synchronous Fpolicy applications (choose two) (from netapp site)
The correct answer is B. file-access and audit logging C. storage resource management. FPolicy in ONTAP supports both synchronous and asynchronous operation modes; only certain application types use the synchronous path where the operation waits for a policy engine response before completing.

Why each option
FPolicy in ONTAP supports both synchronous and asynchronous operation modes; only certain application types use the synchronous path where the operation waits for a policy engine response before completing.
Quota management in ONTAP is handled by the native qtree and volume quota subsystem, not by FPolicy, so it is not an FPolicy application at all.
File-access operations such as open, read, write, and rename are the primary synchronous FPolicy use case because the client request must be held until the external engine responds, enabling real-time access control and audit logging.
Storage resource management applications use synchronous FPolicy to enforce policies such as storage quotas tied to file operations, requiring immediate engine confirmation before the I/O proceeds.
Compression and decompression are data efficiency operations managed by ONTAP's storage efficiency engine and are completely independent of the FPolicy framework.
