Which two solutions would alleviate the QFull errors and performance problems?

A 4-node ONTAP FAS9000 cluster was used to serve I/O from six RedHat 7.3 servers. The servers were configured with maximum, queue depth.

For production purposes, an additional 60 similarly configured hosts were added to the environment. Later, the hosts started reporting random QFull errors, and the aggregated performance degraded.

Which two solutions would alleviate the QFull errors and performance problems? (Choose two.)
A . Remove Selective LUN Mapping (SIM) from the 4-node FAS9000 cluster.
B. Download the latest FC HBA driver, firmware, and BIOS, and deploy them on the hosts.
C. Configure and use additional FC target HBAs in the FAS9000 cluster.
D. Reduce FC HBA gueue depth on the hosts.
