Multiple Choice

In an 8500 Clustered NAS System there are several modules in the cluster communication architecture that work together to implement cluster communication such as resource agent, HAD, Gab, and LLT.  Describe the correct mechanism for these. (Multiple choice.)

A) Agent-Agent monitors the resources of each system and provides the status to each machine's HAD
B) HAD Cluster service that monitors and manages the cluster's NAS
C) Under the management of the master node of the cluster, Gab sends the communication information between the cluster members to the point communication
D) LLT (Low-Latency Transport) sends information to all nodes in the cluster through a low-latency delivery protocol
