Question 37/82
A policy-managed RAC database that hosts the ACCOUNTS service has only three instances running rather than the usual four on a six-node cluster.
Five of the six cluster nodes are active and the sixth (RACNODE6) is down for maintenance.
You decide to check the state of the servers in the server pools to see if there are problems with the OLTP pool to which the ACCOUNTS service has been assigned.
You used the crsctl status server-f command and see that the RACNODE3 node has STATE=VISIBLE.
What is true about this situation?

What is true about this situation?
Correct Answer: A
Explanation/Reference:
Explanation:
Cluster Synchronization Service daemon (CSSD)
An Oracle Clusterware component that discovers and tracks the membership state of each node by providing a common view of membership across the cluster. CSS also monitors process health, specifically the health of the database instance. The Global Enqueue Service Monitor (LMON), a background process that monitors the health of the cluster database environment and registers and de- registers from CSS.
Cluster Ready Services Daemon (CRSD)
The primary Oracle Clusterware process that performs high availability recovery and management operations, such as maintaining OCR. Also manages application resources and runs as root user (or by a user in the admin group on Mac OS X-based systems) and restarts automatically upon failure STATE=VISIBLE Servers that have Oracle Clusterware running, but not the Cluster Ready Services daemon (crsd), are put into the VISIBLE state. This usually indicates an intermittent issue or failure and Oracle Clusterware trying to recover (restart) the daemon. Oracle Clusterware cannot manage resources on servers while the servers are in this state.
