D. You have used crossover cables for the cluster interconnect
Which three statements best describe how Oracle ACFS takes advantage of Oracle ASM?
A. File systems can be dynamically resized.
B. Performance can be maximized through direct access to Oracle ASM disk groups.
C. Oracle ACFS maximizes availability through a dedicated path on the Cluster Interconnect.

Which three statements accurately describe the components of the Cluster Ready Services Technology Stack?
A. Cluster Ready Services (CRS): A specialized oraagent process that helps CRSD manage resources owned by root such as the network, and the Grid virtual IP address
B. Cluster Synchronization Services (CSS):Manages the cluster configuration by controlling which nodes are members of the cluster and by notifying members when a node joins or leaves the cluster
C. Cluster Time Synchronization Service (CTSS): A background process that publishes events that Oracle Clusterware creates.
D. Event Management (EVM). Provides time management in a cluster for Orade Clusterware
E. Grid Naming Service (GNS): Handles requests sent by external DNS servers, performing name resolution for names defined by the cluster.
F. Oracle Agent (oraagent): This process was known as RACG in Oracle Clusterware 11gR1 (11.1).
